Social Stratification and Inequality Study Guide

Unpack the structures and systems that sort people into social hierarchies with this study pack on social stratification and inequality. Cover slavery, caste, and class systems alongside functionalist, conflict, and symbolic interactionist explanations for why stratification persists. From status consistency and occupational prestige to intergenerational mobility myths, this pack addresses the core concepts your sociology exam will test.

Key Takeaways

  • •Social stratification refers to a society's hierarchical ranking of groups based on wealth, power, and prestige, and this ranking determines unequal access to resources and opportunities.
  • •Sociologists identify three primary systems of stratification — slavery, caste, and class — which differ in their rigidity, the basis for rank assignment, and the degree of social mobility they permit.
  • •The three major theoretical frameworks — functionalism, conflict theory, and symbolic interactionism — offer competing explanations for why stratification exists and whether it serves a social purpose.
  • •Social class in modern industrial societies is typically measured by a combination of income, wealth, occupational prestige, and educational attainment, none of which maps perfectly onto the others.
  • •Intergenerational mobility describes movement up or down the class hierarchy across generations, while intragenerational mobility refers to changes within a single person's lifetime; research consistently shows that mobility is more limited than popular belief suggests.
  • •Status consistency — the degree to which a person ranks similarly across different dimensions of stratification — affects social identity, political attitudes, and experiences of inequality.

Defining Social Stratification

Social stratification is the systematic, institutionalized process by which societies rank categories of people in a hierarchy, producing unequal distributions of wealth, power, and social recognition. Understanding what stratification is requires distinguishing it from simple individual differences.

Core Characteristics of Stratification

  • •Stratification is a property of society itself, not just the result of individual variation — the hierarchy is built into institutions like inheritance laws, educational access, and labor markets.
  • •Rankings are reproduced across generations, meaning a person's position is heavily shaped by the family and social group into which they are born.
  • •Every known complex society exhibits some form of stratification, though the specific criteria and degree of inequality vary significantly across cultures and historical periods.

Three Dimensions: Wealth, Power, and Prestige

  • •Wealth refers to accumulated assets minus debts and is distinct from income, which is the flow of earnings received over a period of time; wealth is generally distributed far more unequally than income.
  • •Power, in the sociological sense introduced by Max Weber, is the capacity to achieve one's goals even when others resist — political office, corporate control, and organized labor all represent different sources of power.
  • •Prestige is the social honor or esteem attached to a particular position, occupation, or group, and it can exist independently of wealth (e.g., a highly respected teacher may earn modest income).

Status Consistency and Its Effects

  • •Status consistency describes how closely aligned a person's rankings are across the three dimensions of wealth, power, and prestige.
  • •High consistency — ranking similarly on all three dimensions — tends to produce stable social identities and predictable political behavior.
  • •Low consistency, such as a wealthy business owner with low social prestige or a highly educated worker with low income, often generates social tension and unpredictable political alignments.

Historical and Contemporary Systems of Stratification

Societies have organized inequality in fundamentally different ways across history, and comparing these systems reveals how much variation exists in who gets ranked, on what basis, and how fixed those rankings are.

Slavery as a Closed Stratification System

  • •Slavery assigns the lowest rank by legally defining certain people as the property of others, removing virtually all rights, autonomy, and social mobility.
  • •Slavery has existed in ancient Greece, Rome, colonial Americas, and across Africa and Asia, driven by conquest, debt, and racial classification depending on the historical context.
  • •Sociologists classify slavery as a closed system because legal and social barriers make upward mobility nearly impossible from within the institution itself.

Caste Systems and Ascribed Status

  • •In a caste system, a person's social rank is an ascribed status — assigned at birth based on the family or group one is born into — and is considered permanent and largely unchangeable.
  • •The traditional Indian varna system organized society into ranked occupational groups (Brahmin, Kshatriya, Vaishya, Shudra) with Dalits — formerly called 'untouchables' — existing outside the formal hierarchy entirely.
  • •Caste systems are typically reinforced through religious ideology, endogamy (marriage only within one's caste), and legal restrictions on occupational mobility.

Class Systems and Achieved Status

  • •A class system ranks people primarily on the basis of achieved status — positions and attributes earned through effort, education, and economic activity rather than birth alone.
  • •Class systems are considered relatively open because legal barriers to mobility are absent; however, structural factors like inherited wealth, neighborhood quality, and educational access create de facto barriers that limit actual mobility.
  • •Modern class systems are most common in industrial and post-industrial capitalist economies, where market position is the dominant determinant of rank.
