      "text": "A society is a group of people who live together in an organized community, share a territory and culture, and are bound by common institutions, rules, and patterns of interaction. Societies range from small hunter-gatherer bands to nation-states of hundreds of millions, and the term is used both for whole populations and for the abstract system of relationships that holds them together. The concept is central to sociology, anthropology, and economics, and it underlies much of political philosophy and legal thought.\n\nUnderstanding society matters because nearly every human activity, from raising children and earning a living to governing, worshipping, and learning, takes place within social structures. Those structures shape how resources are distributed, how conflicts are resolved, how knowledge is passed on, and how individuals form their identities. Social scientists therefore treat society both as a product of human action and as a force that constrains and enables that action, a tension that recurs across every major theoretical tradition.\n\nThis entry first defines society and its basic components, including social relations, social norms, and culture. It then examines the main institutions (family, economy, state, law, religion, and education), the processes of socialization and stratification, and the ways power and inequality are organized. Later sections cover typologies of societies and their historical evolution, the principal theoretical perspectives, social change and globalization, research methods, and the relations between societies and their natural environment, health, and international order."

      "heading": "Definition and Scope of the Concept",
      "text": "In sociology, a society is usually understood as a bounded human group that shares a territory, a culture, and a set of organized relationships that persist over time. The definition has two parts. The first is the population: a set of people who live in a common space and reproduce themselves across generations. The second is the set of patterned relations among them, which includes kinship, economic exchange, political authority, and shared obligations. Early sociologists stressed the second part. L. T. Hobhouse described society as a tissue of relationships, and R. M. MacIver and Charles Page called it a web of social relations that is always changing. Talcott Parsons later described society as the most general term for the whole complex of relations among people. In these formulations, the defining feature is not the number of people but the bonds linking them.\n\nPopulation and System of Relations\n\nThe distinction between society as a population and society as a system is central to the concept. A population can be counted by a census and analyzed by demographers, but a count of people does not by itself make a society. Two villages of equal size may differ entirely in sociological terms if one is held together by trade, intermarriage, and shared rituals while the other is an accidental gathering of strangers. F. H. Giddings defined society as a number of like-minded individuals who know their like-mindedness and can therefore cooperate toward common ends. This definition implies reciprocal awareness, meaning that people orient their actions toward one another. Relations of this kind are often invisible and cannot be observed directly. They are inferred from recurring patterns of behavior, expectations, and sanctions. For this reason, many textbooks describe society as abstract in one sense and concrete in another: the people are concrete, while the system of relations that organizes them is not.\n\nRelationship to Related Terms\n\nSeveral neighboring terms are often used interchangeably in everyday speech, but they pick out different features. A community usually denotes a smaller group defined by close personal ties, shared place, or common interests, and it may exist within a larger society. A nation is defined by a shared sense of collective identity and belonging, which may or may not coincide with the boundaries of a political unit. A state is an organization that claims authority within a territory and is recognized as sovereign, as discussed in sovereignty. States and societies overlap but are not identical: a state can govern several societies, and a society can span several states. A civilization is a much broader cultural configuration, typically spanning many societies that share religious traditions, written languages, and urban forms. Anthropology and sociology often differ in how they apply these terms, with anthropologists historically focusing on small-scale cultural units and sociologists on more complex, interdependent populations.\n\nWhy the Concept Is Contested\n\nThe concept of society is contested for at least three reasons. The first is scale. A society may refer to a village, a nation-state, a regional cultural zone, or the entire global population, and the analytical tools that work at one scale may not transfer to another. The second is boundaries. Territory, language, citizenship, religion, and economic ties rarely coincide, so any line drawn around a society involves choices about which criteria matter. Migration, diaspora communities, and transnational trade make these boundaries more porous, and some scholars argue that the idea of a discrete society has become less adequate as a result. The third and most fundamental debate concerns ontology. Émile Durkheim argued that social facts such as norms and collective representations exist external to any individual and constrain behavior, which implies that society is a real entity with its own properties. Other thinkers, particularly those influenced by methodological individualism, have treated society as a convenient abstraction that is ultimately constituted by the actions and understandings of individuals. Most contemporary researchers adopt a middle position, treating society as a real pattern of relations that is reproduced through interaction, while acknowledging that its boundaries and units of analysis are partly a matter of research design."

      "heading": "Social Relations, Statuses, and Roles",
      "text": "Statuses, Status Sets, and Master Statuses\n\nA status is a recognized position within a social structure, and every person occupies several at once. The full collection of statuses a person holds at a given time is usually called a status set. Sociologists commonly divide statuses into two broad kinds. An ascribed status is one a person receives at birth or without choosing it, such as sex, race, parental social class, and biological relationships such as child or sibling. An achieved status is one that a person acquires through effort, ability, or choice, such as occupation, educational credential, or marriage. The distinction was systematized by the anthropologist Ralph Linton, who also noted that the boundary is not always clear. Religion is usually ascribed in childhood, but it becomes an achieved status for someone who converts as an adult.\n\nThe two kinds of status interact. Ascribed characteristics often shape how easily a person can reach achieved positions. Sex, race, ethnicity, and class, for example, affect the chances of finishing college or entering a profession. Achieved statuses can also carry negative as well as positive evaluations, since a society may honor a physician or professor while condemning certain criminal roles.\n\nA master status is a status that dominates the others in most or all social settings. The term was coined by the American sociologist Everett Hughes in the 1940s, with particular reference to race. A master status may be ascribed or achieved, and it can be positive or negative depending on context. Achieved statuses that become master statuses are often marked by a rite of passage, a formal or informal event that changes how a person is classified, as marriage does when a person becomes a spouse. Because a master status is a social label rather than a personal choice, an individual often has limited control over how it is applied in a given interaction.\n\nRoles and the Role-Set\n\nA role is the set of behaviors, rights, and obligations that society expects from a person who occupies a particular status. A professor, for instance, is expected to teach, answer questions, and treat students impartially. Roles are therefore the dynamic side of statuses: a status is a position, and a role is what the position requires in practice.\n\nRobert K. Merton extended this idea by showing that a single status does not carry one role but a cluster of relationships, which he called the role-set. A teacher faces students, parents, colleagues, and administrators, and each of these role partners holds somewhat different expectations about how the teacher should behave. Merton's framework, developed in the 1950s, remains the basis for most later work on role relations.\n\nSocial Networks, Groups, and Organizations\n\nStatuses and roles are the elementary components of social structure, and they combine into larger patterns. A social network is a set of ties linking individuals, and it can be mapped as a web of relationships without any formal boundary. A social group, in the sociological sense, is any collection of people who are, have recently been, or expect to be in some form of interaction with one another. Groups can range from a pair of friends to a large nation-state. Formal organizations, such as firms, schools, and government agencies, are groups with explicit goals, defined membership, and written rules. Networks, groups, and organizations together form the intermediate level between individual roles and the broader institutions discussed elsewhere in this entry.\n\nPrimary and Secondary Groups\n\nCharles Horton Cooley, an American sociologist, distinguished between primary and secondary groups in works from 1902 and 1909. Primary groups are small, and their members interact face to face over long periods in intimate, emotionally significant ways. Families, close friendship circles, play groups of children, and neighborhood groups are the standard examples. Their relationships serve expressive functions, meeting emotional and psychological needs rather than practical goals. Cooley argued that primary groups are fundamental in forming an individual's social nature, values, and sense of self, even though they are not necessarily the first groups in time.\n\nSecondary groups are typically larger, more impersonal, and oriented toward tasks or goals. Work teams, classrooms, trade unions, and political parties are common examples, and their relationships are often more formal and time-limited. Cooley linked the rise of secondary groups to growing scale and complexity, though later scholars have treated this historical claim as a useful generalization rather than a strict law. The two categories are not rigid. Primary groups often form inside secondary ones, as when coworkers become close friends, and in-groups can emerge within a workplace. Face-to-face contact remains the defining feature of the primary group, and sociologists have continued to debate how far mediated communication can reproduce its intimacy.\n\nRole Expectations, Role Strain, and Role Conflict\n\nBecause each status brings expectations from several role partners, individuals regularly face demands that pull in different directions. The sociological literature distinguishes two patterns. Role conflict arises between two or more statuses held by the same person, as when a student who is also an employee is asked to work during class hours. Role strain arises within a single status, when incompatible demands are built into one position. The sociologist William J. Goode defined role strain in 1960 as the stress or friction produced when a single status carries incompatible requirements. Merton's concept of sociological ambivalence, which he described as incompatible normative expectations attached to a status or set of statuses, covers both cases. Sieber (1974) later identified role overload, caused by limited time, as another source of strain.\n\nThese pressures help explain the regularity of everyday behavior. Because role partners expect predictable performance, people tend to develop recurring strategies for managing competing demands, such as setting priorities, delegating tasks, separating contexts, or deferring to the role with the stronger sanctions. Over time these strategies become familiar patterns that others can anticipate. The same structural tensions that create conflict also produce the routines by which individuals and institutions keep social life running, which is why role theory is central to explaining both stability and friction in everyday interaction."

      "heading": "Social Institutions",
      "text": "Sociologists use \"institution\" for the more durable patterns through which a society organizes recurring activity. Jonathan Turner's widely cited definition ties positions, roles, norms and values to particular social structures, and says these arrangements order fairly stable activity around three basic tasks: producing the resources needed for life, reproducing individuals, and keeping the wider social structure viable in its environment Turner's definition (1997) describes an institution as a complex of positions, roles, norms and values lodged in particular types of social structures. Giddens condenses the idea further and treats durability as the trait that distinguishes institutions from other social phenomena Giddens states that institutions by definition are the more enduring features of social life. Geoffrey Hodgson argues that divergent institutional theories converge on a basic view of institutions as established, prevalent social rules that structure interaction Hodgson concludes that divergent institutional theories share a basic definition of institutions as systems of established and prevalent social rules that structure social interactions.\n\nMajor institutions and their functions\n\nTurner's comparative study of institutions covers economy, kinship, religion, polity, law and education The Institutional Order examines economy, kinship, religion, polity, law, and education in evolutionary and comparative perspective. Many other treatments add medicine, which is the institutional form of health care and public health. Each domain addresses a distinct problem:\n\n- Economy organizes the production, distribution and exchange of goods and services (see markets).\n- Family and kinship reproduce members biologically and socially and assign rights and duties between generations (see family and kinship).\n- Polity makes collective decisions and allocates authority, typically through government and the state.\n- Law sets enforceable rules and provides procedures for resolving disputes (see law).\n- Religion supplies shared meaning, ritual and moral sanction (see religion).\n- Education transmits skills, values and knowledge across generations (see education).\n- Medicine maintains health and organizes the treatment of illness (see public health).\n\nThese domains overlap in practice. A school system, for example, depends on public finance, legal recognition of credentials, and family support, which is why institutional analysis tends to examine them as connected systems rather than in isolation.\n\nFormal organizations and informal patterns\n\nHodgson treats organizations as a special type of institution with additional features. Organizations are a special type of institution with additional characteristics; they are bounded institutions with a relatively high degree of cohesion, and their membership, sovereignty and responsibility features strengthen that cohesion. A court, a ministry or a corporation therefore has written charters, recognized members and identifiable decision-makers. Informal institutions, such as queuing conventions, gift-giving etiquette or norms of dialect, lack such charters but still regulate conduct reliably. The distinction is not always sharp, because many formal rules depend on informal foundations. Institutional economists in the Veblenian tradition and pragmatist philosophers argue that institutions work only because the rules involved are embedded in shared habits of thought and behavior. A statute that people routinely ignore therefore has limited institutional force: for new laws to become rules, they have to be enforced to the point that the avoidance or performance of the behavior in question becomes customary and acquires a normative status. Institutions also consist of more than conventions. They consist in part in rules, including but not restricted to laws and regulations.\n\nPersistence and change over time\n\nThe persistence of institutions has been explained through habit. Thorstein Veblen, whose work launched the institutional economics tradition, described institutions as prevalent habits of thought regarding particular relations and functions in a community For Veblen, institutions are in substance prevalent habits of thought with respect to particular relations and particular functions of the individual and of the community. Hodgson builds on this by describing habits as the materials of which institutions are made, which lend them durability and normative legitimacy Habits can be thought of as the materials that make up institutions, providing them with durability and normative legitimacy.. The influence runs in both directions: structures already in place press on the dispositions of the people who live under them Institutions are social structures that involve a downward causation, acting upon individual habits of thought.\n\nAnthony Giddens offers a complementary account centred on practice. He understands institutions as practices that have become routinized across time and space, and a social institution only exists because several individuals constantly make it over and over again. Within his structuration theory, the duality of structure means structure enables and constrains action, while action reproduces or transforms structure. Critics argue that this approach blurs levels of analysis. Nicos Mouzelis contends that Giddens does not adequately distinguish micro-level interaction from large-scale institutional structures Mouzelis argues that Giddens does not adequately distinguish micro interaction from large-scale institutional structures. Treating all structure through duality can blur important levels of analysis.\n\nChange arises from the same mechanisms that sustain institutions. In the Veblenian account, institutional change involves the simultaneous coevolution of both shared prevalent habits of thought and the habits of individuals. Turner's historical work approaches the problem comparatively, examining institutions from their inception and then compares one to another. Institutions also enable as well as restrict. The rules of language allow us to communicate, traffic rules help traffic to flow more easily and safely, and the rule of law can increase personal safety."

      "heading": "Norms, Values, and Culture",
      "text": "Social life rests on shared expectations about conduct. Sociologists have long sorted these expectations by how strongly they are held and enforced. William Graham Sumner's Folkways (1906) gave the distinction its classic vocabulary. Folkways are customary ways of acting that carry little moral weight, such as table manners or appropriate dress for an occasion, and violating them usually brings mild disapproval. Mores are norms seen as essential to a group's welfare, and breaking them provokes condemnation, shame, or exclusion. Taboos sit at the far end of the scale. They are prohibitions so strongly held that transgression is regarded as polluting or sacrilegious. The prohibition on incest is the most frequently cited example and appears in some form in nearly every documented society. Laws are the formal counterpart of this gradient, backed by specialized enforcers rather than by informal sanctions such as gossip, ridicule, or ostracism. The grading is not fixed. A folkway can harden into a more, and a more can be codified as law, while codified rules can also fade into customs that people no longer defend.\n\nValues are broader and more abstract than norms. They are conceptions of what is desirable, from which specific norms derive. Robin M. Williams's 1951 inventory of American values included achievement and success, efficiency and practicality, material comfort, and individualism, and it became a model for later comparative work. Researchers have since tried to measure values across many countries. Geert Hofstede's dimensions, derived from survey data collected from employees of a multinational firm in the late 1960s and early 1970s, contrast power distance, individualism and collectivism, uncertainty avoidance, and masculinity and femininity, with later additions for long-term orientation and indulgence. Shalom Schwartz's theory identifies ten basic values, including self-direction, security, conformity, tradition, benevolence, and universalism, that are said to recur across cultures in different priorities. Both frameworks have been criticized for their samples and for the assumption that national culture can be reduced to a few scores. Still, they show that the ranking of values, rather than the presence of particular values, varies systematically between societies.\n\nCulture, the term anthropologists use to describe learned and shared systems of meaning, is commonly divided into material and nonmaterial components. Material culture includes tools, buildings, clothing, machines, and infrastructure. Nonmaterial culture includes language, symbols, beliefs, rituals, knowledge, and the norms and values described above. Symbols such as national flags, names, and currencies carry meanings that exist only through shared agreement. Language is both a symbolic system and a vehicle for the transmission of other cultural elements. The sociologist William F. Ogburn argued in 1922 that material innovations often outpace the nonmaterial adjustments needed to accommodate them, a gap he called cultural lag. Debates over regulating new technologies, such as automobiles, digital platforms, and artificial intelligence, repeatedly illustrate this pattern, with legal and moral frameworks adapting after the technology has already spread.\n\nCultural variation is the central empirical fact that the study of culture must explain. Early evolutionary accounts ranked societies on a single ladder of progress. Franz Boas and his students rejected this approach in the early twentieth century and insisted that each culture be understood in its own historical context, a position Ruth Benedict popularized in Patterns of Culture (1934). Yet the same research tradition also documented underlying regularities. George Murdock's 1945 list of cultural universals, which included kinship, marriage, language, and the incest taboo, showed that variation takes place within a shared range of human problems. The methodological principle that a culture should be interpreted on its own terms is usually called cultural relativism. As a moral claim, that all values are relative to their culture, it is much more contested. Its critics argue that it cannot easily condemn practices such as slavery or the persecution of minorities, which is why it sits at the centre of debates over universal human rights.\n\nThe opposite error is ethnocentrism, a term Sumner coined in 1906 to describe judging other groups by the standards of one's own. Ethnocentrism distorts both description and comparison, because the observer mistakes local expectations for universal ones. Ethnographic fieldwork, which involves prolonged participant observation, was developed partly to counter this tendency. Recognizing ethnocentrism does not require abandoning moral judgment, however. Most contemporary researchers distinguish between understanding a practice in context and deciding whether it is acceptable, and treat the tension between these two tasks as an open problem rather than a settled answer."

      "heading": "Socialization and the Formation of Identity",
      "text": "Primary and secondary socialization\n\nSocialization is the process by which people acquire the language, norms, values, and roles of the groups they live in. Sociologists usually divide it into two broad phases. Primary socialization begins at birth and usually occurs in intimate, long-term contact with parents or caregivers. In this phase children learn bodily skills, language, and emotional attachment, along with a first sense of what is acceptable. Through the family, children learn how to bond, form relationships, and grasp notions such as trust and belonging.\n\nSecondary socialization takes place later and outside the home, in schools, peer circles, workplaces, and religious bodies, where individuals learn the more specialized rules of wider social domains. It is the socialization that occurs outside of the home. The distinction was popularized in sociology by Peter Berger and Thomas Luckmann in The Social Construction of Reality (1966), who treated secondary socialization as building on a base already laid in childhood. Socialization does not end in adolescence; adults continue to take on new roles, such as occupational or marital roles, though the changes involved are typically smaller than those of early childhood.\n\nAgents of socialization\n\nSeveral agents shape this process. The family is usually regarded as the most influential in early life. Talcott Parsons argued that the family's influence on a child's personality was especially durable, and his functionalist account gave it a central place. It provides the initial social environment where children learn language, emotional regulation, and fundamental moral boundaries.\n\nSchools combine formal instruction with what is often called the hidden curriculum. Alongside academic subjects they teach unstated lessons in discipline, teamwork, and hierarchy. Peer groups offer children a space somewhat independent of adult authority, yet they also exert strong pressure to conform. Mass media, including the internet and social media, can supply large amounts of information about other cultures and social groups, which makes them increasingly important sources of norms and expectations. Workplaces and religious institutions act mainly on adults and young adults, reinforcing occupational norms, professional identities, and moral commitments.\n\nThe effect of these agents is not uniform. Class, ethnicity, and region shape child-rearing practices, and these differences in turn affect children's expectations of schools and institutions. Annette Lareau's Unequal Childhoods (2003) documented how middle-class and working-class families in the United States organized daily life differently, which is one reason socialization can reproduce social stratification as well as transmit shared culture.\n\nTransmission across generations and personal identity\n\nSocialization is the main mechanism by which norms and institutions persist from one generation to the next. Parents, teachers, and peers pass on expectations that are often internalized long before individuals reflect on them, so that social order is maintained largely through routine conformity rather than constant coercion.\n\nPersonal identity is also formed through this process. George Herbert Mead's account in Mind, Self, and Society (1934) held that the self arises through taking the attitudes of others toward oneself. Mead contrasted role-play in early childhood, where one role simply gives way to another without continuity, with an organised game, in which the child must take on the attitudes of all the others involved. Through games, the individual forms what Mead called the generalized other, an organized sense of the expectations shared by the community. On this view, a mature self is one that can view itself from this standpoint, which links individual identity to the moral order of the group. This insight is central to symbolic interactionism.\n\nResocialization and total institutions\n\nResocialization refers to deliberate or forced replacement of a person's existing norms and self-conception with new ones. Erving Goffman studied the most extreme cases in Asylums (1961), based on fieldwork at St. Elizabeths Hospital in Washington, D.C., a federal mental hospital with more than 7,000 patients. He defined total institutions as settings where bureaucratic regimentation and social isolation characterize daily life. Goffman's examples included psychiatric hospitals, internment camps, concentration camps, military boot camps, convents and monasteries, and many scholars also include prisons.\n\nGoffman described several stages through which these institutions reshape identity. Entrants lose the social supports that sustained their former self-image, which is the start of what he called a radical change in their \"moral career\". The process often begins with a degradation ceremony, after which the institution pursues a \"mortification of the self\", stripping away prior identities. Uniforms, shaved heads, and assigned numbers reduce individual distinctiveness, and a system of rewards and punishments encourages conformity to the institution's rules.\n\nGoffman's model has been criticized. Later researchers have argued that his use of the total institution concept seriously challenges his use of the total institution model, and that it places very different settings, such as mental hospitals and prisons, into one category. Resocialization is also not inherently harmful: as the same sources note, total institutions can be used for good or bad purposes, and so can resocialization. Voluntary forms, such as religious conversion, military training, or addiction treatment, illustrate that the same mechanisms can operate through consent rather than coercion."

      "heading": "Social Stratification and Inequality",
      "text": "Dimensions of stratification\n\nSocial stratification is the ranking of people into layers that have unequal access to valued resources. Max Weber separated three dimensions that do not always move together: economic class (position in markets), status (social honour, often expressed through lifestyle and recognition), and party (the capacity to shape collective decisions). Within the economic dimension, wealth and income need to be kept apart. Wealth is a stock, the net value of a person's assets, such as savings, investments or property, after subtracting debts. Income is a flow over a period, and the two can diverge sharply, because a household with large assets may report modest earnings while a household with high pay may hold little net worth.\n\nSystems of stratification and their reproduction\n\nStratification systems differ in how open they are and in what enforces the boundaries.\n\n- Caste assigns people to hereditary, endogamous groups with ritual rankings and fixed occupational associations. The best-documented case is South Asia, historically linked with Hinduism. Its persistence depends on rules of marriage within the group, on restrictions around food and contact, and on the transmission of occupation from parents to children.\n- Estates were legally defined orders, each with its own rights and duties. Medieval and early modern Europe, with its clergy, nobility and commoners, is the standard example. Membership was usually inherited, and the law, not the market, fixed the boundaries.\n- Class is more open-ended. It is defined by economic position and by relations to property and labour. Karl Marx located class in the relation to the means of production, which underpins much of conflict theory. In class societies, advantage is reproduced less by law than by inheritance of property, unequal schooling, family networks and the transmission of cultural resources, including what is sometimes called human capital.\n\nSocial mobility\n\nMobility research asks how far individuals move from the position they started in. Intergenerational mobility compares a person's adult status with that of their parents, while occupational mobility tracks movement between jobs or occupational categories over a career. Analysts distinguish absolute mobility, which is the share of people who end up in a different category, from relative mobility, which is the strength of the link between origin and destination. Absolute mobility can be high even when relative mobility is low, for example when the economy adds many white-collar posts and children move up without changing their rank relative to peers. Rankings are often summarised by the correlation between parental and child earnings or status: a high correlation indicates persistence and low mobility.\n\nMeasuring inequality\n\nCommon measures include the income or wealth shares held by the top 10% or top 1%, quintile ratios, the Palma ratio (the share of the top 10% divided by the share of the bottom 40%), and the Gini coefficient. The Gini is usually computed from the Lorenz curve, which plots cumulative income against cumulative population:\n\n\\[G = \\frac{\\sum_{i=1}^{n}\\sum_{j=1}^{n}|x_i - x_j|}{2n^2\\bar{x}}\\]\n\nHere \\(x_i\\) is the income of unit \\(i\\), \\(n\\) is the number of units, and \\(\\bar{x}\\) is the mean. The value runs from 0 (perfect equality) to 1 (one unit holds everything). Results depend on choices that are easy to overlook: whether incomes are measured before or after taxes and transfers, whether the unit is the individual or the household, which equivalence scale adjusts for household size, and how well surveys capture the very top. Wealth data are especially sparse, so top shares often rely on tax records or national accounts.\n\nRecent evidence\n\nThe 2026 World Inequality Report, produced by the World Inequality Lab, gives some of the most-cited current figures. By 2025, the richest 10% owned about 75% of global personal wealth, the middle 40% held 23%, and the bottom 50% controlled only 2%. On income, the richest 10% received 53% of global income, the middle 40% took 38%, and the bottom 50% earned only 8%. Some secondary reports give the bottom half's income share as below 10%, which is consistent with the figure above. At the top of the wealth distribution, the top 0.001%, fewer than 60,000 multimillionaires, possess three times more wealth than the poorest half of humanity, with their share rising from roughly 4% in 1995 to over 6% today.\n\nWithin countries, the pattern is also stark. For India, the report's figures indicate that the top 10% of earners capture 58% of national income, and the bottom 50% receive only 15%. Wealth is more concentrated still, with the top 1% holding roughly 40% of national wealth. Comparisons of this kind depend on the income definitions used, and figures from different publications may not be strictly comparable."

      "heading": "Power, Authority, and the State",
      "text": "Sociologists usually separate power, the ability to carry out one's will despite resistance, from authority, power that those subject to it consider rightful. Max Weber built his political sociology on this distinction. He argued that durable rule depends on a belief in legitimacy, not on coercion alone, and that most stable orders rest on one of three sources of legitimacy.\n\nThree types of legitimate authority\n\nWeber's typology uses ideal types, which are analytical tools rather than descriptions of any particular government. Traditional authority rests on the sanctity of long-established custom and inherited position. A hereditary monarch who rules because his predecessors did is the classic case. Charismatic authority rests on the extraordinary personal qualities that followers attribute to a leader. Because it depends on a single person, it is unstable and hard to transfer after that person dies. Legal-rational authority rests on belief in impersonal rules and in the right of office-holders to command under those rules. A police officer is obeyed because of the position he occupies, not because of his personality or family history.\n\nWeber also described how charisma becomes routine. When a leader's authority passes to his bloodline, it hardens into a traditional form. When a charismatic movement develops written rules and administrative staff, it becomes legal-rational. Modern democracies rely mainly on legal-rational authority, yet their leaders also draw on tradition and personal appeal, so real systems blend all three.\n\nThe state defined by its means\n\nIn his 1919 lecture \"Politics as a Vocation,\" Weber argued that the state cannot be defined by its goals, because political communities have pursued almost every aim, from empire-building to welfare provision to the enforcement of religious law. He defined it instead by its distinctive means: a human community that successfully claims the monopoly of the legitimate use of physical force within a given territory. Each element matters. Monopoly means that the state seeks an exclusive claim, not merely the largest arsenal. Legitimacy separates state coercion from crime and private violence, which are regarded as unjustified. Territory fixes the area within which the claim applies.\n\nWeber acknowledged that the link between states and force was historically looser. Feudal polities allowed private warfare under certain conditions, and church courts held exclusive jurisdiction over offences such as heresy. The idea itself has older roots in Jean Bodin's Six Livres de la République (1576) and Thomas Hobbes's Leviathan (1651). Critics argue that the definition, by stressing legitimacy, can reinforce existing state authority, so the concept remains contested.\n\nComponents of the modern state\n\nA modern state combines several institutions. A bureaucracy of salaried officials applies rules and carries out policy under a hierarchy of offices. Courts interpret and apply law and settle disputes. Police exercise routine, domestic coercion under legal limits. Armed forces handle external defence and stand behind the state's claim to ultimate force. Tax collection links these institutions to the fiscal base that finances them.\n\nFrom chiefdoms to territorial states\n\nAnthropologists such as Elman Service, Morton Fried and Kent Flannery, writing in the 1960s and 1970s, proposed a sequence of egalitarian societies, ranked societies or chiefdoms, and states. Chiefs often gained power from charisma, warrior prowess or control of key resources, and they commanded labour and redistributed goods. Primary state formation, in which a state emerged without contact with existing states, is rare. Archaeologists usually count only six cases: Mesoamerica, Peru, Egypt, Mesopotamia, the Indus Valley and China.\n\nEarly states took several forms. Southern Mesopotamian city-states such as Ur, Uruk and Lagash appeared around 3500 BCE, while Egypt was unified around 3100 BCE as a large territorial kingdom. Greek poleis such as Athens and Sparta developed different political arrangements. In medieval Italy, city-states such as Venice expanded by absorbing neighbours. Scholars disagree about why large territorial states eventually dominated. Some stress changes in warfare, while others argue that economic resources mattered at least as much; a study of European states from 1100 to 1790 found that small units persisted well into the age of territorial states.\n\nThe modern territorial nation-state developed in early modern Europe. The Peace of Augsburg (1555) tied religious allegiance to territorial rulers, and the Peace of Westphalia (1648) is conventionally cited as the foundation of a system of sovereign territorial states. The nation-state is usually characterized by a defined boundary, a centralized government and a shared national identity. The model later spread worldwide, especially through decolonization in the twentieth century. The transition was gradual rather than abrupt, and historians often describe the same polity as \"territorial\" in one period and \"national\" in another."

      "heading": "Law and Legal Order",
      "text": "Law as a subset of social norms\n\nEvery society regulates conduct through social norms, from informal expectations about greetings to rules about property. Law is distinguished from these norms mainly by how it is enforced. Max Weber held that a convention becomes law when a group with the recognized capacity and duty to impose sanctions takes on the task of punishing violations, as a clan, a priesthood, or a body of elders might. Anthropologist E. Adamson Hoebel offered a parallel definition: a norm is legal when its breach is regularly met, in threat or in fact, by force applied by someone socially authorized to apply it. Weber also noted that informal sanctions such as social boycott can be more damaging than formal ones, so the difference lies less in severity than in the organization and predictability of the response.\n\nContemporary legal theory describes a legal order as a set of primary rules, which impose duties, and secondary rules, which govern how those duties are created, changed, adjudicated, and enforced. Legal systems are administered by specialized officials acting through institutions such as legislatures and courts, whereas informal norms are sustained mainly through reputation, gossip, and disapproval. Like social norms, however, law depends on continued social practice: a rule that officials and the population no longer accept ceases to function as law.\n\nMajor legal traditions\n\nComparative law has traditionally sorted the world's legal systems into families. The two most widely used categories are the common law and civil law traditions. Common law developed in England during the Middle Ages and spread through the British colonies. Its courts relied heavily on precedent, so that judicial decisions shaped later cases. Its position was not secure at first: canon courts applied church law, local courts applied custom, and some courts applied Roman-derived rules. Common law prevailed in the seventeenth century, when Parliament established a lasting check on the English crown and asserted authority to define the common law.\n\nCivil law grew from the revival of Roman law in continental Europe, especially the Corpus Juris Civilis of Justinian, and from the codification movement of the nineteenth century. Examples include the French Civil Code of 1804 and the German Civil Code (BGB) of 1900. In civil law systems, legislation is the primary source of law, and judges interpret and apply codes; precedent is persuasive but historically less binding. Scholars often describe common law reasoning as inductive, moving from cases to general principles, and civil law reasoning as deductive, moving from codified rules to cases.\n\nReligious law forms a third major category. Islamic law, Jewish halakhic law, and classical Hindu legal literature derive their authority from sacred texts and from the interpretive work of religious scholars. Many states combine several traditions. Scotland blends Roman, canon, customary, and English elements, and Louisiana retains civil law rules inherited from its French and Spanish past. Customary law also remains important in much of Africa and Asia, often alongside statutory and religious law. Because these categories overlap and the boundary between common and civil law has narrowed, many scholars now treat legal traditions as patterns that systems combine rather than fixed boxes.\n\nEnforcement, dispute resolution, and judicial review\n\nModern legal orders enforce rules through police, prosecutors, courts, and administrative agencies. Disputes are typically divided into criminal cases, brought by the state against offenders; civil cases, such as contract and tort disputes, brought by private parties; and administrative matters. Many disputes are resolved outside courts through negotiation, mediation, or arbitration, and the threat of litigation shapes most settlements.\n\nA central mechanism for controlling the state itself is judicial review, the power of courts to declare laws or executive acts invalid. The United States Constitution does not expressly grant this power. The Supreme Court established it in Marbury v. Madison (1803), where Chief Justice John Marshall held that a federal statute conflicting with the Constitution could not be applied, making it the first time the Court invalidated an act of Congress. Later, state courts adopted the doctrine, and by 1850 judicial review under state constitutions existed in all states. Constitutional courts in many other countries, and the constitutional authority of courts generally, rest on similar ideas about limiting legislative and executive power.\n\nLaw as stabilizer and instrument of change\n\nLaw stabilizes social order by making expectations predictable. Rules of property and contract allow strangers to trade and invest with confidence, which is a precondition for the large-scale cooperation discussed in the market and money literature. Criminal sanctions and dispute procedures channel conflict into recognized forms rather than private violence. Stability, however, is not neutral. Conflict theorists argue that law often protects the interests of those who hold economic and political power, while functionalists emphasize its role in integrating social institutions.\n\nLaw is also a principal tool of deliberate social change. Legislation abolished slavery, extended voting rights, prohibited racial discrimination in many countries, and reshaped family and property relations, often after long political struggle. Its effects depend on enforcement. A large gap can separate the law on the books from the law in practice, and the outcome of legal reform often depends on the willingness of officials, courts, and communities to apply new rules. For this reason, sociologists study law not only as a set of texts but as a social process in which norms, sanctions, and power interact."

      "heading": "Economy and Exchange",
      "text": "Forms of integration\n\nKarl Polanyi argued that economies are \"embedded\" in social institutions, and he proposed a set of principles for comparing how goods and labour move through a society. In his 1957 essay \"The Economy as Instituted Process,\" he distinguished reciprocity, redistribution, householding, and market exchange as forms of integration. Later anthropologists, notably Marshall Sahlins, refined and extended the scheme. These forms are not stages in a linear development. Several usually coexist in a single society, and each depends on a particular institutional support.\n\nReciprocity is a symmetrical exchange between individuals or groups, often sustained by kinship, obligation, or gift customs. Bronisław Malinowski's study of the Trobriand Islands is a classic reference point. Sahlins distinguished generalized reciprocity, in which no immediate return is expected, from balanced reciprocity, in which a return is due within a set period, and negative reciprocity, in which one party tries to gain at the other's expense.\n\nRedistribution operates through a centre to which goods are collected and from which they are allocated. Temple and palace storehouses in early Mesopotamia, state taxation and tribute in imperial systems, and modern fiscal transfers are all examples. Polanyi's view was that redistribution depends on a recognised centre with the authority to collect and allocate.\n\nMarket exchange is organised around price-forming markets in which parties exchange goods at fixed or bargained prices. Polanyi regarded this as historically the newest form in its dominant position. He argued that when labour, land, and money (which he called \"fictive commodities\") are fully subjected to market pricing, the economy becomes \"disembedded\" from society. In his analysis, this produces a social \"double movement\": societies press back through protective legislation and, in extreme cases, authoritarian politics.\n\nDivision of labour and solidarity\n\nÉmile Durkheim's The Division of Labour in Society (1893) addressed a related question: what binds people together once they depend on one another for production. He distinguished mechanical solidarity, typical of small societies in which individuals share similar beliefs and occupations, from organic solidarity, which arises when specialised roles make people interdependent. For Durkheim, organic solidarity rests on contracts and regulation. When the rules governing specialised exchange break down, the result is anomie, a condition of normlessness. Durkheim's account links the economic form of work directly to the moral integration of a society.\n\nEconomic institutions and inequality\n\nEconomic arrangements shape the distribution of wealth, income, and power. Market exchange rewards bargaining position, which depends on ownership of property and skills, a point Karl Marx developed in his analysis of capital and labour. Redistribution can reduce these gaps through taxes and transfers, and the scale of the state's fiscal role largely determines how far it does so. Polanyi's framework allows a comparison of these combinations. A 2024 study of Hungary, for example, describes how a market-based system combined with low personal taxation and political interventions, while postsocialist reforms moved away from the redistributive planning of the socialist era.\n\nMarkets, money, and property as social constructs\n\nMarkets, money, and property rights are not natural facts; they are institutions that must be defined, enforced, and trusted. Money allows exchange between strangers without personal ties, and its value depends on collective confidence and on central banking and fiscal institutions. Property rights specify who may use, transfer, or exclude others from resources, and they are enforced through courts and police. Contract law makes promises between unrelated parties binding. Anthony Giddens, in a related vein, treated money as a mechanism of \"disembedding\" that allows activities to be coordinated across distance and time. These institutions make large-scale cooperation possible, but they also create the conditions in which inequality and conflict over the rules of exchange arise."

      "heading": "Religion, Belief, and Moral Order",
      "text": "Religion matters to sociology less as a set of doctrines than as a system that produces shared meaning, binds people into moral communities, and gives authority to social arrangements. Émile Durkheim offered the classic definition: a unified system of beliefs and practices about sacred things that unites adherents into a single moral community. On this view, the supernatural content of a faith matters less than the collective commitments it creates.\n\nSacred Classification, Ritual, and Moral Authority\n\nDurkheim's The Elementary Forms of Religious Life (1912) rests on the division between the sacred and the profane. Every religious system, in his account, sets apart certain things, surrounded by prohibitions, from the ordinary world of everyday life. In the emotional intensity of collective rituals, individuals experience 'collective effervescence,' generating moral obligation and the authority of the sacred. The force people feel in a gathering appears to come from outside them, and they attach it to totems, symbols, or deities. The moral weight of religious rules therefore comes from the group that performs the ritual, not from the individual believer alone. Durkheim drew this argument from his reading of Aboriginal Australian clans, where the totem served as a collective representation of society itself.\n\nLater work on ritual has tested and refined this claim, but the basic insight remains: repeated, shared action makes moral expectations feel binding.\n\nCohesion, Identity, and Legitimacy\n\nFunctionalist analyses, associated with structural functionalism, treat religion as a source of social integration. Shared calendars, festivals, and rites synchronize collective life, and religious affiliation marks who belongs to a group and who does not. Religion also legitimates institutions. Monarchies have claimed divine sanction, and in imperial China the idea of Heaven's mandate justified dynastic rule, a link that connects to Confucianism and the state examination system.\n\nConflict theorists stress the opposite side of the same process. Religious doctrine can sanctify existing inequalities, and dominant groups may use religious authority to defend their position. Karl Marx described religion as a response to suffering that also helped to reconcile people to it. Max Weber took a more comparative view, arguing that religious ethics could either support or undermine particular economic and political orders, depending on their content.\n\nMajor World Religions and Their Social Organization\n\nReligious traditions differ sharply in how they organize authority. Pew Research Center's estimates for 2020, based on more than 2,700 censuses and surveys, put Christians as the world's largest group at 2.3 billion representing 28.8%, 2 billion Muslims at 25.6%, 1.9 billion Religiously unaffiliated at 24.2%, 1.2 billion Hindus at 14.9%, 300 million Buddhists at 4.1%, 200 million Other religions at 2.2%, and 10 million Jews at 0.2%. Between 2010 and 2020, Muslims were the fastest-growing religious group over the decade. The number of Muslims increased by 347 million – more than all other religions combined. Buddhists were the only major religious group that had fewer people in 2020 than a decade earlier.\n\nOrganizational forms vary widely. Christianity includes hierarchical churches and decentralized Protestant denominations; the Catholic Church, for example, has 1.3 billion baptized members, with authority running through bishops to the papacy. Islam has no single clerical hierarchy in the Sunni world, where law and community life rest on jurists and mosque institutions, while Twelver Shi'a Islam has developed a more formal clergy. Judaism is organized around rabbinic authority and legal interpretation rather than a central church. Hinduism has no single founder or governing body, and its social life has long been tied to caste-based ritual purity. Buddhism is organized around monastic communities that depend on lay donations, creating exchange relationships between clergy and households.\n\nSecularization and Changing Roles\n\nNineteenth-century thinkers expected religion to fade with industrial society, and mid-twentieth-century social science largely accepted this view. Pippa Norris and Ronald Inglehart have argued that the classic thesis needs revision rather than abandonment. Secularization is a tendency, not an iron law. Their data show that the publics of virtually all advanced industrial societies have been moving toward more secular orientations during the past half century, but also that the world as a whole now has more people with traditional religious views than ever before. Their existential security thesis holds that religiosity persists most strongly among vulnerable populations, especially in poorer nations and in failed states.\n\nSecularization is therefore uneven. It is strongest in wealthy, welfare-providing societies, and weaker where insecurity remains high or where religion is tied to national or ethnic identity. Secularization also does not mean that religion disappears from public life. Religious communities may shift from official authority to voluntary associations, and religious identity may be politicized in new ways. In a global context, the decline of institutional religion in Europe coexists with growing religious populations elsewhere, and the global religious population has grown significantly over the last ten years, showing that secularization is a regional pattern rather than a worldwide trend."

      "heading": "Kinship, Family, and Demography",
      "text": "Kinship systems and descent\n\nKinship consists of the socially recognized relations created by birth and marriage, and anthropologists classify societies by the rules that assign people to descent groups. In unilineal systems, membership passes through one parental line. In patrilineal systems, common among many pastoral and agrarian peoples, descent runs through the father. In matrilineal systems, such as the Trobriand Islands studied by Bronisław Malinowski or the Minangkabau of West Sumatra, it runs through the mother. Bilateral (cognatic) systems trace descent through both parents, which lets individuals claim relatives on either side; this pattern is widespread in contemporary industrial societies. Ambilineal systems, in which individuals choose their group, are rarer. Descent rules shape inheritance, post-marital residence (patrilocal, matrilocal, or neolocal), political authority, and the obligations relatives owe one another.\n\nKinship terminology gives a second way of comparing systems. Lewis Henry Morgan's 1871 study sorted terminologies into types, including Hawaiian, Eskimo, Iroquois, Crow, Omaha, and Sudanese, according to whether cousins are called by sibling terms or by parent terms. Claude Lévi-Strauss's Elementary Structures of Kinship (1949) argued that marriage rules organize the exchange of people between groups and so link kinship to alliance and the incest prohibition. David Schneider later challenged the assumption that \"biological\" kinship is a universal category, and his work pushed the field toward treating kinship as culturally constructed.\n\nForms of family and marriage\n\nA family is commonly defined as a unit of reproduction, child-rearing, and mutual support, and it is distinct from the household, which is a unit of shared residence and may include unrelated members. The nuclear family (parents and dependent children) is one form. Extended families, in which several generations or siblings share a household or economic enterprise, are another. Industrialization, rural-to-urban migration, and rising female employment have shifted many societies toward smaller households, though extended arrangements remain common in much of the world.\n\nMarriage takes several forms: monogamy, polygyny (one man with several wives), and polyandry (one woman with several husbands). George Peter Murdock's cross-cultural survey of ethnographic societies found polygyny permitted in most of the societies in his sample, while polyandry was very rare. Such estimates rest on mid-twentieth-century ethnography and are therefore approximate. Marriage performs economic functions, including the transfer of goods such as bride-wealth, which is common in much of sub-Saharan Africa, or dowry, which is prominent in South Asia and was historically important in parts of Europe. It also performs legal functions: establishing the legitimacy of children, allocating property and inheritance rights, and in modern states defining citizenship and entitlements. Family law and marriage registration are therefore central concerns of the law and of the state.\n\nDemographic structure\n\nDemography describes the composition and dynamics of populations. Age structure is often displayed as a population pyramid, and the dependency ratio compares the number of children and older people with the working-age population. Fertility is measured by the total fertility rate, the average number of children a woman would bear under current age-specific rates. Replacement level in low-mortality countries is about 2.1 children per woman. Mortality is captured by the crude death rate, infant mortality, and life expectancy at birth. Migration is the third component of population change.\n\nMost societies pass through a sequence described by the demographic transition: mortality falls first, usually because of improved nutrition, sanitation, and medicine, and fertility declines later as families adjust. The sequence is not uniform. South Korea's total fertility rate fell to about 0.72 in 2023, among the lowest recorded anywhere, while Japan's population aged 65 and over exceeded 28 percent of the total. Periods in which a falling dependency ratio temporarily raises the share of working-age people are sometimes described as a demographic dividend, a pattern cited in discussions of East Asian growth.\n\nPopulation change and social organization\n\nPopulation size and composition feed back into social organization. Thomas Malthus's Essay on the Principle of Population (1798) argued that population tends to outgrow food supply, a claim later qualified by evidence of technological change. Ester Boserup's The Conditions of Agricultural Growth (1965) reversed the direction of causation, arguing that population pressure stimulated agricultural intensification, and that the shift to intensive farming altered the gender division of labour. Shifts in age structure reshape labour markets, schooling demand, pension systems, and marriage markets. Where sex-selective practices have skewed sex ratios at birth, as in China and India, a shortage of potential spouses has emerged for men, with consequences for household formation. Lower fertility also shrinks kin networks, producing families with fewer siblings and more living grandparents, sometimes called \"beanpole\" families, while urban migration loosens the ties that once depended on proximity to relatives."

      "heading": "Education, Knowledge, and Language",
      "text": "Education is the institution through which a society deliberately passes skills, values, and knowledge to members who lack them. Its forms range from apprenticeship and oral instruction within kin groups to state-run schools with fixed curricula and examinations. Imperial China offers an early case of education tied to state recruitment. The imperial-examination system, which developed in stages from the Sui dynasty onward, selected officials according to mastery of classical texts, and it was not abolished until 1905. In much of nineteenth-century Europe and in Meiji Japan, compulsory mass schooling spread alongside efforts to build national loyalty and a standard language. Schooling therefore does more than transmit competence. As Pierre Bourdieu argued through the concept of cultural capital, it also allocates people to positions, so that educational success often reflects family background and reproduces the stratification described elsewhere in this article.\n\nWriting emerged from practical record-keeping rather than from literature. The development from tokens to script reveals that writing emerged from counting and accounting. Cuneiform, which developed in Sumer in southern Mesopotamia around 3200 BCE, grew out of this accounting tradition, and by the city of Uruk its signs had begun to stand for sounds as well as objects. These early pictographs came to be replaced by phonograms (symbols representing sounds) in the city of Uruk by circa 3200 BCE. The script was adapted to many languages over more than three millennia. Spoken Sumerian was replaced by Akkadian around 2000 BCE, yet continued to be used in writing for religious, artistic and scholarly purposes until about the 1st century AD. For most of this history, reading and writing were specialist skills held by scribes, which made literacy a source of administrative and religious power. The printing press, developed in Europe around 1450, later widened access to texts, though literacy remained unevenly distributed by sex, class, and region.\n\nGlobal literacy has risen sharply in recent decades, but gaps persist. In 2024 the adult literacy rate (ages 15 and over) was 88% and the youth rate (ages 15 to 24) was 93%. In 2024, 739 million adults still lacked basic literacy skills. Nearly 77% lived in sub-Saharan Africa (225 million) and Central and Southern Asia (347 million). Women account for about two-thirds of this population. Measurement itself involves choices: UNESCO's Institute for Statistics computes rates as the number of literate people divided by those whose literacy status is known, so people with unknown status are excluded from the denominator.\n\nLanguage is the medium through which norms, law, kinship terms, and religious practice are expressed, and it also marks group boundaries. Ethnologue's 29th edition puts the figure at 7,170 living languages. Counts differ because the precise number of world languages varies between institutions due to fundamental disagreements about what constitutes a separate language versus a dialect. Many of these languages are under pressure: 3,078 of the world's 7,168 living languages (Ethnologue, 27th Edition) are now classified as Endangered. The field of sociolinguistics studies how language choice relates to power, identity, and social class, while language policy, such as the standardization of national languages in nineteenth-century Europe, has often marginalized regional and minority speech.\n\nKnowledge production is itself socially organized. Medieval universities such as Bologna and Paris were corporate communities of masters and students that controlled teaching licences. The scientific-revolution of the seventeenth century shifted authority toward academies such as the Royal Society, founded in London in 1660, and later toward peer review, professional journals, and competitive research funding. Access to these institutions has long been unequal. emmy-noether, whose theorem linking symmetries to conservation laws remains foundational in physics, lectured at Göttingen for years without a regular salary, because the university did not readily grant a paid academic position to a woman.\n\nContemporary science and scholarship depend on universities, funding agencies, and publishing systems, and these arrangements shape who can take part. Debates over higher-education costs, the digital-divide in access to online learning, and the governance of research data show that the organization of knowledge remains a question of social power as well as of method."

      "heading": "Types of Societies and Social Evolution",
      "text": "Anthropologists and sociologists often classify societies by how they obtain food and by the technologies they use, since these conditions shape population size, mobility, property, and social hierarchy. The standard sequence runs from foraging (hunting and gathering) to horticultural, pastoral, agrarian, and industrial societies. Foraging groups are usually small and mobile. Marshall Sahlins argued in 1966 that such groups, despite material simplicity, could meet their needs with relatively little labor. Horticultural societies grow crops with hand tools such as digging sticks and hoes, which supports permanent villages but rarely large surpluses. Pastoral societies depend on herd animals and tend to be mobile, with wealth held in livestock and social status linked to herd size. Agrarian societies rely on plough agriculture, irrigation, and intensive cultivation. They produce surpluses that support cities, specialist elites, writing, and states, and they are typically marked by pronounced stratification. Industrial societies draw their energy largely from fossil fuels and mechanized production, a pattern that spread from Britain after the industrial-revolution. These categories are analytical ideal types rather than fixed stages. Many societies combined subsistence strategies, and a single category can contain very different political and social arrangements.\n\nTönnies's distinction between Gemeinschaft and Gesellschaft\n\nFerdinand Tönnies published Gemeinschaft und Gesellschaft in 1887, usually rendered in English as Community and Society. He contrasted two ideal types of social bond. Gemeinschaft rests on kinship, locality, custom, and shared belief, and its members act from what Tönnies called natural will, a disposition formed by habit and tradition. Gesellschaft rests on contract, calculation, and exchange among people who remain largely detached from one another, and it reflects what he called rational or artificial will. Tönnies did not claim that any real society was purely one type, and he argued that the growth of markets and cities was moving modern life toward Gesellschaft. His sympathies, however, clearly favored the older communal bonds, which later critics read as a nostalgic judgment on modernity.\n\nThe distinction was taken up in several later traditions. Émile Durkheim's contrast between mechanical solidarity, based on similarity, and organic solidarity, based on the interdependence created by the division-of-labor, follows a similar logic. Robert Redfield's folk–urban continuum, developed in the 1940s, used the same contrast to describe a spectrum from small, homogeneous village life to heterogeneous cities. Critics have argued that these models oversimplify the past, idealize rural solidarity, and treat a process of change as a single, one-directional movement.\n\nUrbanization and changing social life\n\nCities appeared independently in several regions, including Mesopotamia, the Nile valley, the Indus valley, and Mesoamerica, and the emergence of cities is often treated as a turning point in social organization. In a classic formulation published in 1950, V. Gordon Childe listed features that distinguished early cities, among them large dense populations, specialized craft production, concentrated surpluses, monumental public building, writing, and a ruling elite supported by taxation or tribute. Uruk in southern Mesopotamia is often cited as one of the earliest large urban centers, with a population in the tens of thousands by the late fourth millennium BCE.\n\nLouis Wirth's 1938 essay \"Urbanism as a Way of Life\" argued that city life could be explained by three variables: size, density, and heterogeneity. Large, dense, and diverse populations, he suggested, weaken kinship and neighborhood ties, encourage impersonal and segmented relationships, and make anonymity and formal institutions more important. Subsequent research has questioned whether urban life necessarily erodes community, since urban neighborhoods, migrant networks, and voluntary associations often sustain strong personal ties. The debate continues in relation to modern urbanization in the developing world.\n\nUnilinear and multilinear models of social evolution\n\nNineteenth-century theorists proposed that all societies pass through the same ordered stages. Edward Tylor and Lewis Henry Morgan described a progression from savagery through barbarism to civilization, and Friedrich Engels drew on Morgan's scheme. Elman Service's later sequence of band, tribe, chiefdom, and state presented a similar line of political development. These unilinear models were criticized from the late nineteenth century onward, partly because they placed Western societies at the top of a single ladder. Franz Boas's cultural particularism insisted that each culture must be understood in its own historical context.\n\nFrom the 1940s, Julian Steward argued that societies follow several distinct paths of development. His 1955 framework of multilinear evolution emphasized cultural ecology, the way environment and subsistence shape social patterns that recur in similar settings. Marshall Sahlins and Elman Service, in Evolution and Culture (1960), distinguished specific evolution, the adaptive divergence of particular cultural lineages, from general evolution, the broad progression toward greater energy capture and complexity. Chiefdoms illustrate the variation: Polynesian chiefdoms and Cherokee chiefdoms differed widely in size and organization, and not every chiefdom developed into a state. Multilinear accounts remain the dominant framework in contemporary anthropology, though some scholars continue to defend broad evolutionary trends in technology and energy use while rejecting universal stages."

      "heading": "Theoretical Perspectives",
      "text": "Structural functionalism\n\nStructural functionalism treats society as a system of interdependent parts, each explained by the contribution it makes to the stability of the whole. Its roots lie in the organic analogies of Herbert Spencer and Émile Durkheim, but its most systematic mid-twentieth-century form came from Talcott Parsons. In The Social System (1951), Parsons argued that every social system must meet four functional prerequisites, often summarized as AGIL: adaptation, goal attainment, integration, and latency (pattern maintenance). Economy, polity, kinship, and religion could then be read as specialized answers to these needs. Robert Merton refined the approach by distinguishing manifest functions, which are intended and recognized, from latent functions, which are unintended. He also held that one institution may be functional for some groups and dysfunctional for others. In 1945, Kingsley Davis and Wilbert Moore applied the logic to stratification, arguing that unequal rewards motivate talented people to fill the most important positions.\n\nCritics have raised several objections. The approach tends to assume that arrangements persist because they are useful, which risks explaining an institution's existence by its effects and neglecting how it arose through conflict or accident. Its emphasis on equilibrium made it poorly suited to rapid change, and many of its concepts were considered too abstract to test. Functionalism lost its dominance in American sociology by the 1960s, yet its questions about integration and system needs persist in systems analysis and comparative research.\n\nConflict theory\n\nConflict theory holds that social life is organized around struggles over scarce resources, and that the most consequential of these struggles occur between groups defined by their relation to the means of production. In The Communist Manifesto (1848), Karl Marx and Friedrich Engels declared that the history of all hitherto existing society is the history of class struggles. In his 1859 Preface to A Contribution to the Critique of Political Economy, Marx described a base of productive forces and class relations on which a legal and political superstructure and forms of consciousness rest. He argued that the ruling ideas of each age are those of its ruling class, and that law and the state tend to protect the interests of owners. Under capitalism, he held, workers sell their labour power and are alienated from its products, and the tension between developing productive forces and existing property relations generates revolutionary pressure.\n\nLater theorists extended these ideas in several directions. Max Weber offered a multidimensional model of stratification (class, status, and party) that complicated purely economic accounts. Ralf Dahrendorf (1959) moved attention from ownership to authority, locating conflict in relations of command and obedience within industrial organizations. Randall Collins emphasized status competition and credential inflation as sources of conflict over education. Conflict perspectives have also been central to feminist and postcolonial scholarship on gender, race, and empire. Critics contend that the approach overstates class as an explanatory axis, underplays shared values and cooperation, and has at times been bound up with political projects whose outcomes were disputed.\n\nSymbolic interactionism\n\nSymbolic interactionism focuses on how people create shared meanings through everyday interaction. Its origins lie in the lectures of George Herbert Mead at the University of Chicago, published posthumously as Mind, Self, and Society (1934). Mead argued that the self emerges by taking the perspective of others, and that communication through significant symbols, especially language, makes this possible. Herbert Blumer coined the term \"symbolic interactionism\" in 1937 and set out its premises in 1969: people act toward things according to the meanings those things have for them, meanings arise from social interaction, and they are modified through an interpretive process. Erving Goffman's The Presentation of Self in Everyday Life (1956) used theatrical metaphors to analyze impression management. Howard Becker's Outsiders (1963) showed how deviance is produced when rules are applied to particular people. W. I. Thomas's observation (1928) that situations defined as real are real in their consequences captures the approach's core claim about the power of definitions.\n\nCritics, including many conflict theorists, argue that a focus on face-to-face meaning-making can underweight the constraints of large-scale structures, inequality, and power. These forces shape which meanings are available and whose definitions prevail.\n\nPoints of overlap and disagreement\n\nThe three traditions share the view that society is an emergent order that cannot be reduced to isolated individuals, and that shared symbols and norms are essential to social life. Parsons and Marx both analyze large structures such as economies and institutions, and both assume that these structures shape individual lives. Conflict theorists have drawn on interactionist insights when explaining how domination is sustained through everyday acceptance rather than force alone.\n\nThe disagreements are more fundamental. Functionalism and conflict theory give opposite answers to whether order rests on consensus or coercion. Parsons assumed that shared values integrate society, whereas Marx saw stability as the product of class domination. Functionalists often treat inequality as serving some role in the system, while conflict theorists treat it as the central phenomenon to be explained and changed. The traditions also differ in scale: functionalism and conflict theory operate mainly at the macro level, while interactionism works at the micro level. Their epistemological commitments differ as well, since the first two seek explanatory accounts of structure, while the third stresses that social reality is constituted through interpretation. Later work, including Anthony Giddens's structuration theory and Pierre Bourdieu's concept of habitus, has tried to bridge the divide between structure and agency."

      "text": "Social change has several recurring sources. Technological invention, shifts in how production is organized, armed conflict, and environmental pressure can each reshape institutions, and they often reinforce one another. This section looks at how these forces worked during industrialization and how they now move across borders.\n\nIndustrialization and its social effects\n\nHistorians generally date the start of industrialization to Britain in the middle of the eighteenth century. Most historians place the origin of the Industrial Revolution in Great Britain in the middle decades of the 18th century. Its demographic effects were quick. Britain's population grew from about 6 million in 1750 to 21 million in 1851. The 1851 census in Britain revealed that, for the first time, more people were living in towns and cities than in the countryside. In 1800, about 20 percent of the British population lived in urban areas. By the middle of the nineteenth century, that proportion had risen to 50 percent.\n\nUrban life also altered the household. Dense towns brought young people together, and marriages happened earlier, and the birth rate went up compared to societies in rural areas. Work moved out of the home. Before factories, a decentralized form of employment was called the \"putting-out\" or domestic system. Factory production later meant a separation of the home from the workplace for most male workers. Many workplaces became dangerous, and the workforce became much less skilled than previously. Overcrowding, weak sanitation, and air pollution made industrial towns unhealthy, particularly for the youngest members of society.\n\nClass structure shifted as well. Competing with large mills required machinery that was far beyond the capabilities of the working class. The route from wage worker to employer narrowed, and an urban middle class grew up, but the gulf between those at the bottom and the top, if anything, widened. Mass-produced goods also reached working-class households, which gave rise to a new consumer culture.\n\nGlobalization of trade, communication, and migration\n\nThe same kind of transformation has operated across national boundaries in recent decades. Technological change has compressed both time and space and brought geographically distant cultures into closer contact than has previously been possible. Migration has grown with it. The UN estimates that in 2024 the number of international migrants worldwide stood at 304 million, a figure that has nearly doubled since 1990. Migrants made up 3.7 percent of the world's population in 2024, and 48 percent (146 million) of all international migrants were women or girls. Such flows put local labor markets, household arrangements, and public services under new pressure, and they bring communities into sustained contact with one another.\n\nCultural diffusion and hybridization\n\nSociologists often distinguish three outcomes of cultural globalization: homogenization (cultures becoming more alike), hybridization (cultures blending to create new forms), and heterogenization (the strengthening of cultural diversity in response to global forces). In practice, all three processes operate at once, often within the same society. In Jan Nederveen Pieterse's account, local cultures integrate new cultural elements while retaining their basic identities. Reggaeton is a common illustration: it fused Jamaican dancehall with Latin rhythms and American hip-hop.\n\nRoland Robertson's term \"glocalization\" describes how global forces are always modified by local conditions. The term emerged in the 1980s, and its proponents stress that local actors take an active part in shaping what arrives from outside. The opposing concern, that dominant cultures marginalize others, is captured by the notion of \"cultural imperialism,\" where one culture becomes dominant and others are marginalized. Shared institutions such as written constitutions, bureaucratic administration, and mass schooling have also spread across societies, though local conditions shape how they are adopted and adapted."

      "heading": "Research Methods for Studying Society",
      "text": "Social scientists use several families of method, and each suits a different kind of question. Quantitative work relies on surveys of samples, censuses that try to count an entire population, and statistical models that relate measured variables to one another. Its main strength is scale: it can estimate how common a pattern is and how strongly two variables move together. Its weakness is that the categories it uses (occupation, household, ethnicity) are themselves products of earlier social decisions and can obscure the processes they describe. Census and survey data are the basis of demographic analysis and of much research in statistics.\n\nQualitative methods answer questions that counts cannot. Ethnography is the most intensive of these. It often entails deep immersion into a field site, sometimes lasting over a period of months or even years, so that the researcher can develop a member's-eye view. The main technique is participant observation, in which the researcher takes part in a community's activities while recording what happens. The label \"ethnography\" also names the written monograph that results. The term was first coined in 1924 by Eduard C. Lindeman, but the method was truly shaped by social anthropologist Bronislaw Malinowski during his work in the Trobriand Islands. Malinowski's rules, which called for long residence, language learning, and detailed records of daily life kept in a field diary, remain the foundational principles of ethnographic fieldwork even today. Good fieldwork also depends on trust. Rapport is a sense of trust and a comfortable working relationship between researcher and informants, and it is sustained by careful written notes. Interviews, life histories, document analysis, and case studies are common companions to observation, and they let researchers compare what people say with what they do.\n\nComparative and historical methods examine social processes across times and places in order to test claims beyond a single setting. Comparative historical research is a method of social science that examines historical events in order to create explanations that are valid beyond a particular time and place. Its logic often draws on John Stuart Mill's methods of agreement and difference: a researcher selects cases that share an outcome and looks for a common factor, or selects cases that differ in the outcome and looks for the factor that varies. Classic studies in this tradition include work by Adam Smith, Alexis de Tocqueville, Karl Marx, Max Weber, Barrington Moore, Charles Tilly, and Theda Skocpol. The approach is well suited to large-scale questions such as state formation, revolution, and democratization, where a single case rarely supplies enough variation to test a claim. Its practitioners often combine both comparative and within-case methods, which lets them balance general explanations against detailed understanding of particular cases.\n\nThe hardest problem in social research is causal inference: establishing that one factor produces a change in another rather than merely accompanying it. A causal effect is usually defined by comparing outcomes with and without the treatment for the same population, written as \\(\\mathbb{E}[Y(1)] - \\mathbb{E}[Y(0)]\\). Because the counterfactual outcome cannot be observed directly, researchers must find a valid comparison group. The gold standard is the randomized controlled trial, in which the researcher assigns subjects to treatment or control by chance. Randomized experiments are often unethical or unfeasible, however, and most social phenomena (policies, migration, income shocks) cannot be assigned by a researcher at all. Observational studies are usually feasible but lack the random assignment that renders randomized experiments causally informative.\n\nNatural experiments offer a partial remedy. A natural experiment is an observational study that uses naturally occurring situations, like policy changes or weather events, to create conditions similar to a randomized experiment. The 2021 Nobel Prize in Economic Sciences recognized this shift: the committee praised work shifting the focus in empirical research using observational data towards relying on quasi-experimental variation to establish causal effects. Three designs are prominent: standard natural experiments, instrumental-variable designs, and regression-discontinuity designs. The last of these compares observations just above and just below an eligibility threshold, on the assumption that individuals near the cutoff are otherwise similar. Natural experiments carry serious limits. Even when an intervention is assigned as if at random, random assignment of the intervention is not sufficient to provide an unbiased estimate of the causal effect, and the required additional assumptions are often hard to check. Policy changes may also be driven by the same political forces that shape the outcome, which undermines the claim that they are exogenous. For these reasons, causal claims from social data are usually treated as provisional until they have been tested through several designs and replicated across settings."

      "text": "Sources and limits of international law\n\nRelations between states are governed by international law, but the system has no world legislature, no executive with general enforcement powers, and no court with compulsory jurisdiction over all states. Article 38(1) of the Statute of the International Court of Justice (1945) is the usual reference point for its formal sources. It lists international conventions (treaties), international custom understood as a general practice accepted as law, and the general principles of law recognized by civilized nations. Judicial decisions and the writings of highly qualified publicists appear as subsidiary means for determining the law. Treaties bind only the states that consent to them, which is why they are the most explicit source. Custom requires both a widespread practice among states and a belief that the practice is legally required, so it changes slowly and is often contested. Because the Statute itself confines the binding force of an ICJ judgment to the parties in the case, the court's authority rests largely on the willingness of states to comply.\n\nInstitutions of global governance\n\nThe modern framework was built after the two world wars. The League of Nations (1920) and its Permanent Court of International Justice were unable to prevent the Second World War. The United Nations Charter, signed in San Francisco in 1945, created a General Assembly in which each member has one vote, a Security Council with primary responsibility for international peace and security, an International Court of Justice, and a Secretariat. Under the Charter, the Security Council may authorize binding measures, including sanctions and the use of force under Chapter VII. Its procedure is governed by Article 27, which requires nine affirmative votes on substantive matters, including the concurring votes of the five permanent members (China, France, Russia, the United Kingdom, and the United States). This gives each permanent member a veto, which has blocked action on conflicts where a permanent member or its ally was involved. Critics treat the veto as a major obstacle to responding to atrocities, while defenders argue it keeps great powers committed to the organization. The General Assembly's 1950 Uniting for Peace resolution allowed it to consider collective measures when the Council is deadlocked, though its recommendations are not binding. Individual criminal responsibility took a further step with the Nuremberg and Tokyo tribunals (1945–1946) and, later, the International Criminal Court, established by the Rome Statute in 1998 and operational from 2002. The Court depends on state cooperation for arrests and has no police force of its own, and several major powers, including the United States, China, and Russia, are not parties to it.\n\nThe Universal Declaration and the idea of universal rights\n\nThe Universal Declaration of Human Rights was drafted in the Commission on Human Rights between 1946 and 1948, with cultural differences and colonial conditions debated throughout. Eleanor Roosevelt chaired the commission, René Cassin of France prepared the first draft, and John Humphrey of Canada shaped its structure. The General Assembly adopted it on 10 December 1948 with eight abstentions and no votes against. The Declaration is not a treaty and has no direct legal force, but it became a reference point for later instruments. The International Covenant on Civil and Political Rights and the International Covenant on Economic, Social and Cultural Rights were adopted in 1966 and entered into force in 1976, and regional conventions in Europe, the Americas, and Africa followed. Many national constitutions also incorporate its principles. The claim that rights apply across all societies has been contested. Some governments and scholars argue that the Declaration reflects Western liberal assumptions and downplays collective or religious values, and the 1990 Cairo Declaration on Human Rights in Islam set out a different framework grounded in Islamic law. The 1993 Vienna Declaration affirmed that human rights are universal while acknowledging that national and regional particularities must be considered.\n\nSovereignty and international obligation\n\nThe tension between sovereignty and international obligation is central to this field. The UN Charter affirms the sovereign equality of member states and, in Article 2(7), limits UN intervention in matters essentially within domestic jurisdiction, though not Chapter VII enforcement. Human rights treaties, by contrast, create obligations that states accept voluntarily but that concern how they treat their own citizens. The 2005 World Summit endorsed the principle of a \"responsibility to protect\" populations from genocide, war crimes, ethnic cleansing, and crimes against humanity, while stating that collective action should be taken through the Security Council. Military interventions have tested these principles. NATO's 1999 campaign over Kosovo took place without explicit Security Council authorization, and the 2003 invasion of Iraq was similarly contested. Each case raised the question of whether protecting human rights can justify actions that bypass sovereign consent. Most states accept that sovereignty and human rights are both part of the current order, but the balance between them, and the authority to decide when one should yield to the other, remains disputed among governments, courts, and scholars. The state thus remains the primary actor in international life, even as the norms governing its conduct increasingly extend beyond its borders."

      "heading": "Society and the Natural Environment",
      "text": "Dependence on ecosystems and natural resources\n\nEvery society draws on ecosystems for food, water, fuel, building materials and fibre, and relies on the atmosphere to supply air and to absorb wastes. Agrarian societies depended on soil fertility, rainfall timing and forest cover. Industrial economies added fossil fuels, mineral extraction and large-scale chemical discharges, and their scale now affects the planet's systems as a whole. Many environmental problems arise because resources are held in common and access is open. The economist Garrett Hardin named this pattern the tragedy of the commons in 1968. Elinor Ostrom later documented many cases in which communities governed shared pastures, forests and irrigation systems through locally made rules and monitoring, which shows that the outcome depends on institutions as well as on resource scarcity.\n\nThe atmosphere is the clearest case of a shared resource whose overuse produces global effects. The dynamics of climate-change therefore link local land use, national energy policy and international negotiation.\n\nEnvironmental change and social response\n\nSocieties respond to environmental stress in several ways: they change crops and farming practices, build storage and irrigation, diversify trade, move populations, and revise property and governance rules. The response is shaped by wealth, technology, political organization and information. The Dust Bowl of the 1930s illustrates how these elements interact. Prolonged drought and the plowing of grassland on the American Great Plains led to severe wind erosion, which drove many farm families from their land and prompted federal soil-conservation programmes. Adaptation has social costs, however, and those costs usually fall first on the poor, who have the fewest alternatives.\n\nResource management involves designing institutions that match the rate of extraction to the rate of renewal. Examples include fishing quotas, water-allocation rights, forest co-management, and the regulation of pollutants. Such measures succeed when monitoring is credible, property and use rights are clear, and affected groups participate in decisions.\n\nSustainable development as a framework\n\nThe idea of sustainable development became prominent through the 1987 report Our Common Future, produced by the World Commission on Environment and Development under the chairmanship of Gro Harlem Brundtland. The report argued that the worst environmental problems stemmed from extreme poverty in poorer regions and from unsustainable patterns of production and consumption in richer ones, and it called for a strategy that treated development and environmental protection as one project. Its formulation has since been used to link economic prosperity, social inclusion and environmental stewardship, and the European Union cites it as the basis for much of its policy. Later agreements, from the 1992 Rio Earth Summit to the Sustainable Development Goals adopted by the United Nations in 2015, have turned the concept into measurable targets. Critics note that the framework's three pillars often treat ecological limits as one consideration to be traded against economic growth, rather than as hard constraints.\n\nHistorical cases of environmental collapse\n\nHistorical cases show that environmental change seldom produces collapse on its own. The lowland Classic Maya polities of Mesoamerica declined during the Terminal Classic period (roughly 800–900/1000 CE). Sediment isotopes from Lake Chichancanab in Mexico indicate that annual rainfall fell by about 41 to 54 percent during the collapse, with peak droughts reducing it by as much as 70 percent. Yet a 2025 study of Classic Maya urbanism argues that many cities were abandoned after conditions had improved, as rural households left crowded urban settings for greater autonomy. Bioarchaeological evidence from Mayapan links a drought in the 1400s to factional violence and the abandonment of that city, which suggests that drought acted through political conflict.\n\nEaster Island (Rapa Nui) is the other frequently cited case. Jared Diamond's Collapse (2005) presents the island as a near-pure example of ecological self-destruction, in which deforestation led to food scarcity and social breakdown before European contact. Archaeologists such as Terry Hunt and Carl Lipo contest this narrative. They argue that introduced Polynesian rats were a major cause of forest loss, that population was probably smaller than Diamond assumed, and that the most severe decline followed European contact and epidemic disease. The debate remains unresolved, and it shows how reconstructions of past environmental impact depend on evidence, interpretation and the political meaning attributed to the story.\n\nThese cases suggest that environmental stress tends to interact with trade, warfare, disease and institutional choices, and that the same ecological shock can produce different social outcomes."

      "heading": "Health, Well-Being, and Social Determinants",
      "text": "The social-determinants-of-health are the conditions in which people are born, grow, live, work and age, together with the systems set up to deal with illness. The World Health Organization treats these conditions as shaped by a wider set of forces, including economics, social policy and politics, and by how money, power and resources are distributed at global, national and local levels. WHO's 2008 Commission on Social Determinants of Health gave the concept its modern form. Sociologists and public health researchers use the framework to explain why health varies systematically across social groups rather than only across individuals. A useful distinction separates structural determinants, such as class, gender and race-ethnicity and the way they shape access to power and resources, from intermediary determinants, such as employment conditions, housing, transport and psychosocial stress. In this framework the structural factors are the root causes that operate through the intermediary ones.\n\nThe pathways are concrete. Income affects the quality of food and housing a household can afford and whether it can pay for care. Education shapes the jobs people can obtain and their ability to understand health information. Social networks provide practical support, information and emotional buffering during illness. These factors also interact in feedback loops. Poor health or limited schooling can reduce employment prospects, lower income restricts access to care and nutritious food, and sustained hardship produces stress that can encourage smoking, heavy drinking or poor diet. The contrast in child survival illustrates the scale of the problem: WHO notes that infant mortality is about 2 per 1,000 live births in Iceland but above 120 per 1,000 in Mozambique.\n\nA central finding of this literature is the social gradient. WHO states that at all levels of income, health follows a gradient in which lower socioeconomic position is associated with worse health. The Whitehall studies of British civil servants, led by Michael Marmot from the 1970s, were decisive in showing this. Men in the lowest employment grade had a mortality rate roughly three times that of men in the highest grade, although none were poor by ordinary standards. Gradients appeared across most major causes of death. Conventional risk factors such as smoking, obesity, blood pressure and physical activity explained no more than about 40 per cent of the difference in coronary heart disease mortality. Researchers therefore turned to psychosocial explanations, notably low job control and relative deprivation, along with the accumulation of socially patterned exposures over the life course. Later analyses found that relative differences narrowed but persisted after retirement, and that the debate over causal interpretation remains active. The term health inequity marks the subset of differences that are avoidable and unjust, and it is this category that policy seeks to reduce.\n\nHealth systems sit at the end of this causal chain. Public health institutions, including ministries of health, surveillance agencies and local services, shape how risks are monitored and how care is delivered and financed. Access to primary care, the distribution of clinics and the cost of treatment all influence who receives timely care, and these patterns often reproduce existing inequalities. WHO and regional bodies such as PAHO promote intersectoral action, in which health, education, labour, environment and social development ministries coordinate policies, because health outcomes depend heavily on decisions made outside the health sector. Universal coverage and universal-health-coverage reforms are one attempt to link access to care with broader social protection, though their effects vary widely across countries.\n\nMeasuring well-being has its own difficulties. Gross domestic product is a poor proxy for how people actually live, because it counts market production rather than distribution, health or leisure. The 2009 Commission on the Measurement of Economic Performance and Social Progress, chaired by Joseph Stiglitz, Amartya Sen and Jean-Paul Fitoussi, recommended moving toward multidimensional measures. It identified material living standards, health, education, personal activities including work, political voice, social connections, environmental conditions and economic and physical security as key dimensions. It urged attention to inequality within each dimension and to both objective indicators, such as life expectancy, and subjective measures of life satisfaction. Its recommendations helped shape later national dashboards, including those developed by the OECD. Life expectancy, mortality-rate and self-reported health are commonly paired with income and education data to assess the health of a population. Such indicators can show where social position and health diverge, but they rarely establish causation without careful study design, a point taken up in the discussion of causal-inference."
