Basic Concepts and Institutions

Sociological concepts

Society is a system of social relationships and institutions within which people live, while culture is the shared system of meanings, symbols, norms, values, beliefs and material objects through which life is organised. Material culture includes tools, buildings and technologies; non-material culture includes language, ideas and rules. Norms are shared expectations for behaviour, values are broader beliefs about what is desirable, and sanctions are rewards and punishments that encourage conformity. Folkways are everyday customs, mores are norms tied to moral judgement, and laws are formalised norms backed by the state. Socialisation is the lifelong process through which individuals learn culture, develop a self and learn to participate in society. Primary socialisation occurs in early family life, secondary socialisation in schools, peer groups, workplaces and media, and resocialisation occurs when a person must learn a radically new role, as in a total institution.

Status is a position in a social structure, and role is the expected behaviour attached to that status. Ascribed status is assigned at birth or without choice, such as being born into a caste or family, while achieved status is gained through effort, such as becoming a teacher. A person holds a status set of multiple positions and a role set of expectations attached to one status. Role conflict occurs when expectations from different statuses clash, and role strain occurs when expectations within a single role clash. A group is a collection of people who interact, share identity and norms, and recognise membership. Primary groups are small, intimate and long-lasting, such as family and close friends, while secondary groups are larger, impersonal and goal-oriented, such as a company or university. In-groups define belonging, out-groups define contrast, and reference groups provide standards for evaluation and aspiration. Ferdinand Tonnies contrast of Gemeinschaft, community based on close bonds and shared life, with Gesellschaft, association based on impersonal interests and contracts, remains useful for describing urbanisation and modernisation, provided it is not treated as a simple story of loss. Social control operates through formal sanctions such as law and punishment, and informal sanctions such as praise, ridicule and ostracism. Deviance is behaviour that violates norms, but what counts as deviance depends on audience, context and power, so labelling perspectives ask who gets to define deviance and with what consequences.

Social institutions

An institution is a durable, patterned system of norms and roles that organises a recurring social need. The family organises kinship, reproduction, socialisation and care, though its form varies across cultures and changes with economy, law and gender relations. Marriage is a socially recognised union that regulates sexuality, reproduction, property and alliance, and kinship systems define who counts as related and what obligations follow. The economy organises production, distribution and consumption through markets, firms, households and state regulation, while polity organises legitimate power, decision-making and conflict through governments, parties, courts and administrations. Religion organises beliefs and practices concerning the sacred, offering meaning, community, moral regulation and, at times, legitimation for hierarchy or motivation for protest. Education organises transmission of knowledge, skills and credentials, and also sorts people into positions, reproducing or challenging inequality depending on access and curriculum.

Institutions interlock. A change in economy, such as expansion of service work or migration for jobs, reshapes family care, marriage timing, education demand and religious practice. A change in law can redefine marriage, inheritance or citizenship, with effects on family and economy. Institutions also contain conflict: schools can both equalise opportunity and reproduce class advantage; religion can both console and mobilise; markets can both expand choice and deepen insecurity. Functionalist accounts stress how institutions meet needs and maintain order, conflict accounts stress how institutions distribute power and resources, and feminist accounts stress how institutions organise gendered labour and authority. A strong examination answer shows both integration and tension: it explains what an institution does, for whom, under what conditions, and what happens when its norms are contested. Institutions persist because they are embedded in law, habit, material interests and identity, but they change when economic conditions, movements, technologies or state policies alter the costs and meanings of following old patterns.

Social stratification

Social stratification is the structured ranking of individuals and groups by unequal access to valued resources, status and power. It is systematic, not random: patterns persist across generations and are legitimated by ideologies that make inequality appear natural, deserved or inevitable. Class is commonly understood through relation to production and markets: ownership of capital, occupation, income, education and life chances. Marx emphasises ownership of means of production and exploitation, Weber adds market position, status honour and party power, and later approaches add occupation, credentials and consumption. Caste in India is a distinctive system combining hereditary membership, endogamy, occupational association, ritual hierarchy and, historically, purity and pollution, though its contemporary operation is also shaped by land, politics, education and reservation. Gender stratification organises unequal access to work, property, authority and bodily autonomy through norms, institutions and violence. Ethnicity, race, age, disability and region add further axes, and intersectionality insists that these axes interact: a person position is shaped by combinations, not by adding separate disadvantages mechanically.

Mobility describes movement within stratification. Intergenerational mobility compares parents and children, intragenerational mobility tracks a lifetime, vertical mobility moves up or down a hierarchy, horizontal mobility moves between similar positions, and structural mobility occurs when the occupational structure itself changes. Open systems allow relatively more mobility, closed systems restrict it through birth, law or custom, but no system is fully open or closed. Life chances, in Weber sense, are the probabilities of securing goods, health, education and security given class position, and they connect stratification to everyday outcomes without reducing people to their category. Stratification is also cultural: taste, language, dress and credentials signal and reproduce distinction, as Bourdieu shows through cultural capital. For the examination, avoid describing stratification as mere difference: difference becomes stratification when it is ranked, institutionalised and linked to unequal life chances, and when it is defended or challenged by ideologies, policies and movements.

Social change and processes

Social change is alteration in social structure, institutions, culture and relationships over time. It can be gradual or rapid, planned or unplanned, partial or transformative, and it is rarely uniform: one institution may change quickly while another resists. Evolutionary theories describe change as movement through stages toward greater complexity, but they risk treating Western development as universal destiny. Cyclical theories describe rise and decline, functionalist theories describe differentiation and adaptation to maintain equilibrium, and conflict theories describe change through contradiction, class struggle and movements. Modernisation theory linked development to urbanisation, industrialisation, literacy, secularisation and democratic values, but critics argued it treated tradition as an obstacle, ignored colonialism and dependency, and mistook one path for all paths. Dependency and world-systems approaches reversed the lens, arguing that underdevelopment is produced by unequal incorporation into a global economy, not by internal backwardness alone.

Key processes help organise analysis. Industrialisation reorganises production around factories, wage labour and technology; urbanisation concentrates population and diversifies occupations and lifestyles; secularisation describes declining religious authority in public institutions, though not necessarily declining personal belief; globalisation intensifies worldwide connections through trade, migration, media and finance; and individualisation describes loosening of ascribed bonds and greater emphasis on choice and self-making. Diffusion spreads traits across societies, invention creates new practices, and discovery reveals new knowledge, but adoption depends on power, interests and cultural fit. Social movements are organised challenges to existing arrangements, from reformist campaigns to revolutionary projects, and they succeed partly through resources, political opportunities, framing and networks. Change also produces unintended consequences: a policy meant to expand education can intensify credential competition, and a technology meant to connect people can create new forms of exclusion. A good answer therefore distinguishes direction, pace, scope, agents and consequences, and asks who benefits, who bears costs, and what remains unchanged.
