Social stratification explained for GCSE Sociology

Social stratification is the way societies arrange people into a hierarchy of layers, with some groups holding more wealth, status, or power than others. In plain language: It is how a society sorts its members, often by class, but also by gender, ethnicity, age, and religion.

This guide covers the main types of stratification, the sociologists you need to name in your AQA exam, the difference between open and closed systems, and the wording that picks up easy marks in 12-mark questions.

Social stratification is the division of a society into ranked layers, called strata. Each stratum shares similar levels of wealth, status, or power. The word comes from geology, where strata are the layers of rock in the earth, and sociologists borrowed it to describe how groups stack up in society.

At GCSE you will be expected to know that stratification is structured, persists over generations, and affects life chances. It is not random inequality between individuals, it is patterned inequality between groups.

AQA expects you to know four main systems of stratification: Slavery, caste, feudalism (estates), and social class. The first three are described as closed systems because movement between layers is very limited. Social class is described as an open system because, in theory, people can move up or down through education, work, or wealth.

An open system allows social mobility, meaning people can move up or down the hierarchy during their lifetime. A closed system blocks mobility, so your position is fixed at birth and stays with you.

The UK is usually described as an open system because, in principle, education and work can change someone's class position. Sociologists argue mobility is more limited in practice than the open model suggests, especially at the very top and very bottom. (John Goldthorpe is widely cited on social mobility but is an A-level addition rather than a GCSE spec-named thinker.)

Examiners reward students who name and explain at least two contrasting theorists. The GCSE spec-named stratification thinkers are Karl Marx, Max Weber, the functionalists Kingsley Davis and Wilbert Moore, Sylvia Walby (feminist), Peter Townsend (poverty), and Charles Murray (New Right view of the underclass). Naming any of these in an answer picks up AO1 marks.

Karl Marx argued that stratification in capitalist societies is rooted in the economy. He identified two main classes: The bourgeoisie, who own the means of production (factories, land, capital), and the proletariat, who sell their labour for wages.

For Marx, stratification is a tool of exploitation. The bourgeoisie keep their position by extracting surplus value from workers. He predicted that class conflict would eventually lead to revolution and a classless society.

Max Weber agreed that economic class matters, but argued stratification also has two other dimensions: Status (social prestige) and party (political power). A person could be high in one and low in another, like a wealthy criminal with low status or a respected teacher with low pay.

Weber's three-dimensional model is useful because it explains why class alone does not capture everything about a person's position in society.

Kingsley Davis and Wilbert Moore argued that stratification is necessary and beneficial. They claimed society needs to fill important roles (like doctors or engineers) with talented people, and the way to encourage talented people to train for those roles is to reward them with higher pay and status.

Critics say this view ignores barriers like poverty and discrimination that stop talented people from ever reaching the top, no matter how hard they work. (Melvin Tumin is often cited here but is an A-level addition rather than a GCSE spec-named thinker.) On the GCSE spec, Peter Townsend's work on relative poverty shows that stratification leaves whole groups unable to meet the living standards considered normal in society, while Charles Murray argues from a New Right view that a 'dependency culture' among the welfare-reliant underclass perpetuates stratification.

Feminist sociologists argue that class-based models miss a key axis of stratification: Gender. Sylvia Walby identified six structures of patriarchy, including paid work, housework, and the state, that systematically place women below men.

Intersectional feminists add that stratification by gender interacts with ethnicity and class, so a Black working-class woman experiences stratification differently from a white middle-class woman. (Kimberlé Crenshaw, who coined intersectionality, is widely cited here but is an A-level addition rather than a GCSE spec-named thinker.)

Modern sociologists stress that class is only one form of stratification. Gender, ethnicity, age, religion, and disability all stratify society and shape life chances. AQA Paper 2 questions often ask you to apply this to specific examples.

For instance, the gender pay gap, ethnic differences in school exclusion rates, and age discrimination in hiring are all evidence that stratification works on more than one axis at a time.

Most lost marks on stratification questions come from vague answers rather than missing knowledge. Examiners want named theorists, defined key terms, and a clear point being made, not a general essay on inequality.
