Mastering Social stratification and inequality: IGCSE Sociology Study Notes

Why stratification sits at the centre of sociology

Every society that has ever been studied by sociologists exhibits some form of ranking. Whether the divisions run along lines of wealth, ethnicity, gender, caste, or age, human communities consistently organise themselves into layers where some groups hold greater access to resources, prestige, and influence than others. Social stratification, the structured ranking of entire groups within a hierarchy, is not a side topic in IGCSE Sociology. It is the thread that connects nearly everything else on the syllabus: the family structures students study on Paper 2, the educational inequalities they analyse, and the patterns of crime and deviance they evaluate all trace back, in significant part, to how a society distributes its rewards and burdens.

Understanding this section thoroughly therefore pays dividends well beyond the stratification questions themselves. Candidates who grasp the core concepts here, achieved versus ascribed status, the mechanics of social mobility, the tension between meritocratic ideals and structural barriers, find that their answers on education, family, and crime become sharper and more sociologically grounded. The opposite is also true: candidates who treat stratification as an isolated chapter tend to produce answers elsewhere that lack the structural depth examiners reward at the highest levels.

Core concepts and definitions

What stratification means

Social stratification refers to the division of a society into hierarchical layers, or strata, based on unequal access to valued resources such as wealth, income, power, and status. Unlike individual differences in talent or effort, stratification describes patterns that persist across generations and affect entire categories of people rather than isolated individuals. A factory worker's child growing up in a low-income household faces systematically different life chances from those available to the child of a corporate executive, not because of any inherent difference between the two children, but because of the structural position each family occupies.

Stratification systems compared

The distinction between these systems matters because IGCSE Sociology questions frequently ask candidates to compare them or to evaluate whether modern class systems genuinely offer the social mobility they claim to provide. A strong answer recognises that while class systems are formally open (no law prevents a working-class child from becoming a surgeon), structural barriers such as unequal access to quality education, cultural capital, and professional networks mean that mobility is far from guaranteed.

Social mobility

Social mobility describes the movement of individuals or groups between positions in the social hierarchy. Sociologists distinguish between two forms. Intergenerational mobility measures whether a person occupies a higher or lower social position than their parents: a teacher whose parent was a manual labourer has experienced upward intergenerational mobility. Intragenerational mobility tracks movement within a single person's lifetime: an office clerk who retrains as a solicitor has moved upward within their own career trajectory.

The concept of meritocracy, the idea that a society distributes rewards according to individual talent and effort rather than inherited privilege, is closely tied to mobility. Functionalist sociologists such as Davis and Moore argued that inequality is necessary because it motivates the most talented individuals to fill the most demanding roles. Critics, particularly from the Marxist tradition, counter that meritocracy functions more as an ideology than a reality, legitimising existing inequalities by attributing them to personal merit while obscuring the structural advantages that benefit those already at the top.

Poverty, wealth, and power

Defining poverty

Poverty is one of the most frequently examined concepts within this section, and candidates must be precise about the distinction between its two main definitions.

Explanations for poverty divide broadly into two camps. Individualistic explanations attribute poverty to personal failings: lack of ambition, poor decisions, dependency on welfare. The American sociologist Charles Murray advanced a version of this argument through his concept of the "underclass," a group allegedly trapped in poverty by a culture of welfare dependency. Structural explanations, favoured by most sociologists, locate the causes of poverty in the organisation of society itself: low wages, insecure employment, inadequate housing, underfunded schools, and discrimination based on class, gender, or ethnicity. The sociologist Peter Townsend demonstrated through extensive research that poverty is not simply about income but about exclusion from the customs, activities, and living conditions that are widely accepted in a given society.

Wealth and income

Wealth (the total value of assets a person owns, including property, savings, and investments) and income (the money received regularly through employment, benefits, or returns on investment) are related but distinct. A retired homeowner with substantial property wealth may have a modest monthly income, while a young professional with a high salary may have accumulated little wealth. Sociologists are particularly interested in the distribution of wealth because it is far more unequally distributed than income in most societies. A small percentage of the population typically holds a disproportionately large share of total wealth, and this concentration tends to reproduce itself across generations through inheritance.

Power

Power, the ability to influence or control the behaviour of others even against their resistance, is the third pillar of stratification alongside wealth and status. Karl Marx argued that economic power is the foundation of all other forms: those who own the means of production (factories, land, capital) control not only the economy but also the political system, the legal framework, and the dominant ideas of their era. Max Weber offered a more nuanced model, identifying three distinct but overlapping dimensions of power: class (economic position), status (social prestige and honour), and party (political organisation and influence). Weber's framework allows for situations where these dimensions do not perfectly align: a university professor may hold high status but modest wealth, while a successful entrepreneur may possess great wealth but limited social prestige in certain circles.

Life chances and inequality

The concept of life chances, originally developed by Weber, refers to the opportunities and experiences available to individuals based on their position in the social hierarchy. Research consistently demonstrates that a person's class position correlates with measurable differences in health outcomes, educational attainment, housing quality, employment security, and even life expectancy. These correlations are not coincidental; they reflect the systematic ways in which stratification channels resources toward some groups and away from others.

Gender, ethnicity, and age interact with class to produce overlapping patterns of advantage and disadvantage. A working-class woman from an ethnic minority background may experience compounded inequalities that a middle-class man from the same ethnic group does not. Sociologists use the term intersectionality to describe how multiple dimensions of inequality combine and reinforce each other, producing experiences that cannot be fully understood by examining any single factor in isolation.

Theoretical perspectives

Functionalism: inequality as motivation

Davis and Moore (1945) argued that social stratification is universal and functionally necessary. Their reasoning runs as follows: every society must fill a range of positions, some of which require greater skill, longer training, or heavier responsibility than others. To motivate talented individuals to undertake the sacrifices necessary to prepare for these demanding roles, society must offer unequal rewards. Inequality, in this view, is not a defect but an incentive structure that benefits the whole society by ensuring that the most capable people occupy the most important positions.

The functionalist position has attracted substantial criticism. Tumin pointed out that it fails to account for inherited wealth and privilege, which allow less talented individuals to occupy high-status positions without competing on merit. It also assumes a consensus about which roles are "most important" that may not exist: nurses and refuse collectors perform essential functions, yet their pay and status do not reflect this according to the functionalist logic.

Marxism: class conflict and exploitation

Marx argued that stratification originates in the relationship between those who own the means of production (the bourgeoisie) and those who must sell their labour to survive (the proletariat). The bourgeoisie extract surplus value from workers by paying them less than the full value of what they produce, and this exploitation is the engine of class inequality. Marx further argued that the ruling class maintains its dominance not only through economic power but through ideological control: the education system, the media, religion, and the legal system all function, in this analysis, to present capitalist inequality as natural, inevitable, or deserved.

Critics of Marx note that class structures have proved more complex and fluid than his two-class model predicted. The growth of a substantial middle class, the rise of the welfare state, and improvements in working conditions have not followed the trajectory of intensifying polarisation that Marx anticipated. Weberian sociologists argue that status and political power operate with significant independence from economic class, making a purely economic model insufficient.

Weberian sociology: a multi-dimensional model

Weber accepted that class, understood as economic position, is a major source of inequality, but insisted that it does not operate alone. Status groups (communities that share a common level of social honour or prestige) and parties (organised groups that seek to influence policy) represent distinct dimensions of stratification that cannot be reduced to economics. This framework allows sociologists to account for situations that Marxism struggles to explain: why some wealthy individuals lack social prestige, why some high-status groups (such as clergy) may have modest incomes, and why political movements sometimes cut across class lines.

Reducing inequality: policies and their effectiveness

Governments have adopted various strategies to reduce the effects of social stratification. IGCSE Sociology questions frequently ask candidates to evaluate the success of these measures, which requires both knowledge of the policies themselves and the ability to weigh evidence for and against their effectiveness.

Globalisation and inequality between societies

Globalisation, the increasing interconnection of the world's economies, cultures, and populations through trade, technology, and migration, has reshaped patterns of inequality both within and between nations. Transnational corporations (TNCs) operate across borders, locating production where labour costs are lowest and selling products in the wealthiest markets. Proponents argue that this process has lifted hundreds of millions out of absolute poverty, particularly in rapidly industrialising nations. Critics counter that the benefits of globalisation are distributed unequally: TNCs may generate employment in low-income countries, but often under conditions of low pay, limited labour rights, and environmental degradation that would not be tolerated in wealthier nations.

Migration is another dimension of globalisation with stratification implications. Workers who migrate from lower-income to higher-income countries may improve their individual life chances, but they frequently occupy the lowest rungs of the labour market in their destination country, performing low-paid, insecure work that native-born workers are reluctant to accept. Remittances sent home can benefit families and communities in the origin country, yet the loss of educated and skilled workers ("brain drain") may simultaneously weaken the capacity of those countries to develop their own institutions.

The IGCSE Sociology syllabus expects candidates to evaluate these competing perspectives rather than to adopt a simple position for or against globalisation. A strong answer recognises that globalisation produces both winners and losers, and that the distribution of gains and losses is itself shaped by existing patterns of stratification.

Worked example: structuring an evaluative answer

Consider the following examination question: "To what extent has the welfare state been successful in reducing social inequality?" (15 marks)

Step 1: identify what the question requires

The phrase "to what extent" signals an evaluative question. The candidate must present evidence that the welfare state has reduced inequality, evidence that it has not (or has done so only partially), and a substantiated conclusion that weighs the two sides.

Step 2: plan arguments for both sides

Arguments that it has reduced inequality:

• The introduction of the National Health Service removed financial barriers to healthcare, improving health outcomes for lower-income groups
• State education provides universal access to schooling regardless of family income, creating at least the formal possibility of social mobility
• Unemployment benefits and housing assistance prevent the most extreme forms of absolute poverty

Arguments that it has been limited or unsuccessful:

• Relative poverty has persisted despite decades of welfare provision, suggesting that the welfare state manages inequality rather than eliminating it
• Middle-class families are often better positioned to benefit from public services (e.g. understanding how to navigate the education system, access to better-resourced schools in wealthier areas)
• Marxist sociologists argue that the welfare state functions to maintain the existing class structure by providing just enough support to prevent social unrest without challenging the fundamental distribution of wealth and power

Step 3: write a substantiated conclusion

The conclusion should not simply restate both sides. It should weigh them: "The welfare state has been effective in reducing absolute poverty and providing universal access to essential services. Its record on reducing relative inequality is less convincing. The gap between the wealthiest and poorest members of society has, in many countries, widened even during periods of welfare expansion. This suggests that while the welfare state is necessary for preventing the most severe forms of deprivation, it is insufficient on its own to dismantle the structural inequalities rooted in the distribution of wealth, power, and cultural capital."

Common mistakes and how to avoid them

Self-check questions

1. Define the difference between achieved and ascribed status. Give one example of each that you could use in an examination answer.
2. Explain two differences between a caste system and a class system of stratification.
3. Identify and briefly explain three factors that affect a person's life chances.
4. Outline the functionalist argument for why social inequality is necessary. Then state one criticism of this argument.
5. Explain what Marxists mean when they describe the education system as reproducing class inequality.
6. Distinguish between absolute poverty and relative poverty. Why does the distinction matter when evaluating the effectiveness of the welfare state?
7. Evaluate whether progressive taxation is an effective method of reducing social inequality. Include at least one argument for and one against.
8. Explain how globalisation can both reduce and increase inequality between societies.
9. A question asks: "To what extent is modern society a meritocracy?" Plan the main points you would include on each side of the argument.
10. Why do sociologists argue that class, gender, and ethnicity should not be studied in isolation from each other?

Working through these questions with full written answers, rather than brief notes, builds the fluency and precision that distinguish strong IGCSE Sociology candidates. Each question targets a concept or skill that appears regularly in past papers, so practising them systematically creates a direct link between revision effort and examination performance.
