Cambridge O Level Sociology: Social Stratification and Inequality, Topic 3 (2251)

This guide expands on Topic 3: Social Stratification and Inequality, part of Paper 1 in Cambridge O Level Sociology (2251). The site’s existing guide to Paper 1: Research Methods, Identity and Inequality covers all three Paper 1 topics, with Topic 3 discussed mainly through its connection to Topic 2 (Identity) – this guide develops Topic 3’s own content in depth. (In the syllabus, 1.1-1.3 are the three sub-topics of Topic 1, Research Methods; Topic 3’s sub-topics are numbered 3.1-3.3.)

Where this fits in 2251

Social Stratification and Inequality examines how societies are divided into unequal groups, why those inequalities persist, and what has been attempted to reduce them. It builds on Topic 2’s account of how identity is formed, since a person’s stratified position (by class, gender, or ethnicity) both shapes and is shaped by the identity they develop.

Syllabus coverage

CAMBRIDGE O LEVEL SOCIOLOGY (2251) – TOPIC 3: SOCIAL STRATIFICATION AND INEQUALITY

• 3.1 What is social stratification? – stratification in open and closed societies (achieved and ascribed status, poverty and wealth, power, social mobility, meritocracy, modern slavery, the caste system); differences in life chances (education, employment, health, housing, life expectancy) affected by age, gender, ethnicity and social class; the intersectionality of age, ethnicity, gender and social class; sociological theories of inequality, including labelling theory and Marxism
• 3.2 What attempts have been made to reduce social inequalities? – legislation, welfare states and the global work of NGOs, and sociological views of how successful these attempts have been
• 3.3 How has globalisation affected inequalities between societies? – migration, global ecological issues, and sociological explanations for global inequalities

This guide develops the core of 3.1 in depth – life chances, meritocracy, gender and ethnicity, and a Marxist explanation; 3.2 and 3.3 are listed so the whole topic is in view.

How to approach it

This topic rewards candidates who can move between description (what inequality looks like) and explanation (why it exists and persists) – a strong answer does not simply list types of inequality but draws on a sociological perspective, such as a Marxist account of class inequality, to explain their origins.

Life chances: the concept that ties this topic together

Life chances refers to a person’s opportunities to improve their quality of life – access to good education, secure employment, healthcare, and material security. Sociologists use this concept to show that stratification is not simply an abstract label but has concrete, measurable consequences: someone born into a higher social class typically has statistically better access to these opportunities than someone born into a lower one, independent of individual effort. This is the concept most exam questions on this topic ultimately return to, whether the question is framed around class, gender, or ethnicity.

Meritocracy and its sociological critique

A meritocracy is a system in which social position is determined by individual ability and effort rather than by inherited advantage. Many societies present themselves as broadly meritocratic, but sociologists studying stratification frequently challenge this self-image, arguing that unequal starting points (in family wealth, education access, or social networks) mean that outcomes are not purely a reflection of individual merit – a candidate who defines meritocracy but does not also engage with this critique is likely missing half of what this part of the topic tests.

Gender and ethnicity as forms of stratification

Gender-based inequality examines how differences in the treatment, opportunities and expectations placed on men and women affect life chances – for example, historical and ongoing disparities in access to particular careers, pay, or domestic responsibilities. Ethnicity-based inequality examines how a person’s ethnic background can affect their treatment and opportunities within a society, including experiences of discrimination or unequal access to institutions such as education or employment. Both forms of inequality are best understood alongside class, since a full sociological picture of any individual’s life chances usually requires considering how class, gender and ethnicity combine, rather than treating any one factor as the sole explanation for their circumstances.

Worked example: applying a Marxist explanation to a scenario

The routine below is an original model written for this resource, not a reproduction of any official past paper or mark scheme.

Scenario: "Two children from different social class
backgrounds achieve different levels of educational success."

Step 1 - identify the Marxist concept being applied:
e.g. that the education system tends to reproduce existing class
inequality rather than neutrally rewarding ability.

Step 2 - explain the specific mechanism:
e.g. a child from a wealthier background may have access to
private tutoring, more educational resources at home, and
cultural capital that aligns with how schools assess success.

Step 3 - connect the mechanism to the concept of life chances:
e.g. this unequal access to educational resources translates
into unequal life chances in adulthood, including access to
higher-paid employment.

Step 4 - acknowledge a limitation or counter-view where relevant:
e.g. individual ability and effort still play some role, and not
every child from a given class background follows the same
outcome.

Common mistakes

Describing types of inequality (class, gender, ethnicity) without explaining how they specifically affect life chances. Defining meritocracy without engaging with the sociological critique of how meritocratic a society actually is. Applying a Marxist perspective as a label without explaining its specific mechanism in the scenario given. Treating class, gender and ethnicity as entirely separate forms of inequality, rather than showing awareness that they can intersect and compound one another for a given individual.

Quick revision checklist

• Be able to define social stratification and explain the concept of life chances clearly.
• Prepare a Marxist explanation of class inequality, including its specific mechanism, not just the label.
• Understand and be able to critique the concept of meritocracy.
• Practise applying stratification concepts to a given scenario, rather than only reciting definitions.
• Revise how class, gender and ethnicity can intersect in shaping an individual’s experience of stratification.
