Estimated study time: 55-65 minutes
Social stratification and differentiation A-Level Sociology revision introduces one of the central themes running throughout the AQA course: how people are divided into social groups and how these divisions can become inequalities. You will distinguish social differentiation from social stratification, consider class, status, power and life chances, and begin applying these ideas to contemporary society. These foundations prepare you for later work on social class [Social class], gender [Gender], ethnicity and age. AQA explicitly requires students to examine stratification, differentiation and dimensions of inequality.

Social stratification and differentiation A-Level Sociology revision overview
AQA identifies social differentiation, power and stratification as one of the core themes of A-Level Sociology. Within the Stratification and Differentiation topic, students must understand stratification and differentiation by social class, gender, ethnicity and age. They must also examine class, status and power, differences in life chances, changing structures of inequality and social mobility.
This first lesson establishes the concepts that organise the rest of the topic. Later lessons examine each dimension in greater depth.
What is social differentiation?
Social differentiation refers to the distinctions sociologists make between different categories or groups within society.
For this topic, AQA specifically requires you to consider differentiation according to:
social class
gender
ethnicity
age
These categories allow sociologists to investigate whether different groups occupy different social positions or have different experiences.
A social difference becomes especially important to the study of stratification when it is connected to unequal status, power, resources or life chances.
For example, identifying two occupational groups is a form of social differentiation. If those groups also differ in income, authority or opportunities, the distinction is connected to social inequality.
You will examine these divisions individually in ethnic inequality [Ethnicity] and age-related inequality [Age].
What is social stratification?
Social stratification refers to structured inequalities between social groups.
The idea of stratification therefore goes beyond simply noticing that people are different. It concerns differences that place individuals or groups in unequal social positions.
Stratification can involve inequalities in:
economic resources
occupational position
social status
power
opportunities and life chances
The concept is central to this topic because the specification asks students not only to identify patterns of inequality, but also to understand sociological explanations of those inequalities.
Differentiation compared with stratification
Social differentiation | Social stratification |
Identifies distinctions between social groups. | Concerns structured inequalities between groups. |
May involve categories such as class, gender, ethnicity or age. | Examines how groups may occupy unequal social positions. |
Focuses on social difference. | Focuses on inequality, ranking, resources, status, power and life chances. |
Helps sociologists identify groups for comparison. | Helps sociologists explain patterns of inequality between those groups. |
📌 Exam tip: Do not treat the two concepts as interchangeable. An answer on stratification needs to show how a social difference becomes connected to inequality.
How societies organise inequalities
AQA requires students to consider several dimensions of inequality rather than treating inequality as a single economic issue.
The three dimensions specifically identified are:
Class
Status
Power
These dimensions may be related, but they describe different aspects of a person's or group's position.
Understanding their relationship is developed further in dimensions of inequality [Class, status and power].
Social class
Social class refers to people's position within a system of socio-economic inequality.
Class can be connected to differences in resources, occupation and life chances. A person's class position may therefore be associated with opportunities in areas such as education, employment and health.
AQA also requires students to examine the problems involved in defining and measuring social class, so class should not be treated as a simple or completely fixed category.
Later revision on measuring class [Defining and measuring social class] examines these problems directly.
Status
Status refers to a person's or group's social position or standing.
People may therefore differ not only in their economic position but also in the status attached to their position.
A person's status and class may be connected, but Sociology does not require you to assume that they are always identical. This is why AQA lists class and status separately as dimensions of inequality.
Questions can ask you to apply status to particular social groups. For example, previous AQA assessment has required students to analyse how gender and age may affect an individual's status.
Power
Power concerns the ability of individuals or groups to influence decisions or outcomes.
Power inequalities can therefore exist:
between social classes
between genders
between ethnic groups
between different age groups
within organisations and institutions
AQA assessment has, for example, linked power to differences in earnings and access to senior workplace positions. This demonstrates why inequality cannot be reduced to income alone.
Inequality is multidimensional
A society may contain several forms of inequality at the same time.
A person's social position could therefore be connected to:
Dimension | What sociologists may examine |
Social class | Differences in socio-economic position and resources |
Status | Differences in social position or standing |
Power | Differences in the ability to influence decisions or outcomes |
Gender | Patterns of inequality between gender groups |
Ethnicity | Patterns of inequality between ethnic groups |
Age | Patterns of inequality between age groups |
The purpose of studying stratification is therefore not simply to identify which people have more or less. Sociologists also investigate how inequalities are organised and why they exist.
Life chances
AQA specifically requires students to study differences in life chances by:
social class
gender
ethnicity
age
disability
Life chances are the opportunities individuals or groups have to experience particular outcomes in life.
In AQA questions, life chances can be connected to areas such as:
education
employment
income and economic circumstances
health
occupational opportunities
social mobility
For example, an inequality that restricts access to particular occupations may affect both employment opportunities and the possibility of upward social mobility.
The detailed evidence is developed through class and gender inequalities [Social class, gender and life chances] and other dimensions of life chances [Ethnicity, age, disability and life chances].
From social difference to unequal life chances
A useful chain of reasoning for examination answers is:
Social difference → social position → access to resources or power → different opportunities → unequal life chances
Consider two occupational groups.
If they simply have different jobs, this illustrates differentiation.
If one group also receives greater rewards, has greater workplace authority and has access to opportunities unavailable to the other, the difference illustrates stratification.
Those inequalities may then produce different life chances.
This type of explanation is important because AQA questions frequently require students to connect two parts of the topic rather than simply describe one concept.
Social stratification is not only about social class
Social class is a major part of the topic, but AQA requires a wider approach.
Stratification and differentiation must also be examined in relation to:
gender
ethnicity
age
Disability must be considered when examining differences in life chances.
This matters in examination questions because a question about "inequality" does not automatically mean "class inequality". You must identify the dimension named in the question and keep your answer focused on it.
Sociological explanations of stratification
The specification requires sociological explanations of the content within this topic. Past AQA assessment shows that students may need to compare different theoretical explanations of why inequality exists.
Functionalist explanations
Functionalist explanations view stratification as connected to the organisation and stability of society.
AQA assessment has presented the functionalist argument that stratification can contribute to social order, with members of society sharing a value consensus that supports the system of inequality. Functionalist explanations may therefore see stratification as necessary or beneficial rather than simply as a social problem.
From this perspective, differences in social rewards and positions can be connected to the allocation of people to different roles.
Marxist explanations
Marxist explanations emphasise social class and conflict.
AQA has presented Marxist stratification in terms of a capitalist society divided between:
the bourgeoisie, who own the means of production
the proletariat, who sell their labour power
The different interests of these classes create class conflict. Stratification is therefore interpreted as an unequal structure rather than something that necessarily benefits society as a whole.
You will develop class-based explanations further in class inequality [Social class].
Feminist explanations
Feminist explanations focus attention on gender inequality and the social position of women.
Rather than treating social class as the only important division, feminist approaches examine how gender can structure inequalities in areas such as social position, power and life chances.
This becomes particularly important when evaluating the claim that one dimension of inequality is more important than another.
Consensus and conflict
These theoretical approaches introduce a broader disagreement within Sociology.
A consensus approach can explain stratification in terms of social order and shared values.
A conflict approach can instead emphasise unequal interests, unequal power and advantages enjoyed by particular groups.
This distinction is useful when analysing any claim about inequality:
Is inequality presented as necessary?
Is it presented as the result of conflict?
Who benefits from the arrangement?
Are opportunities distributed equally?
Does one dimension of inequality matter more than another?
These questions move an answer from simple description towards sociological analysis.
Stratification can change
Structures of inequality are not treated by the specification as unchanging.
AQA requires students to examine:
changes in structures of inequality
globalisation
the transnational capitalist class
the implications of these changes
These issues are examined fully in changes to inequality [Changing structures of inequality].
For this introductory lesson, the important point is that sociologists investigate both the organisation of inequality and how that organisation may change over time.
Stratification and social mobility
Social mobility concerns movement within a system of social stratification.
If society contains unequal social positions, individuals may potentially move between those positions.
AQA requires students to examine:
the nature of social mobility
its extent
its significance
Social mobility is therefore closely connected to stratification. Patterns of mobility can provide evidence about how open or closed opportunities within a society may be.
You will examine this directly in movement between social positions [Social mobility].
Applying stratification to contemporary society
In an examination, you may be given a situation involving different social groups rather than being asked directly to define stratification.
For example:
A workplace has several occupational groups. Some employees have greater authority over decisions and receive greater rewards than others.
A strong sociological application would identify:
Differentiation, because employees occupy different occupational positions.
Stratification, because the positions involve unequal rewards or authority.
Power inequality, because some workers have more control over decisions.
Possible differences in life chances, because positions may provide unequal resources or opportunities.
The key skill is to connect the context explicitly to sociological concepts rather than merely repeating the information given.

Hints from the Examiner Reports 💡
Examiner hint: Keep every paragraph focused on the exact relationship named in the question. Examiners have repeatedly noted that students sometimes write everything they know about a concept instead of answering what has actually been asked. Successful 10-mark responses make a relevant point and then develop it sociologically.
Examiner hint: In a 10-mark "analyse" question with an item, use the specific prompts in the item. AQA reports refer to these prompts as "hooks". They must be applied to the question rather than merely copied or described. Two clearly separated, developed points are more effective than several undeveloped ones.
Examiner hint: For 20-mark evaluation questions, use other theories to evaluate the theory or claim named in the question. In the 2023 Stratification question, comparison became ineffective when students allowed alternative perspectives to criticise each other instead of using them to evaluate Marxism.
Examiner hint: Avoid turning an evaluation answer into separate descriptions of several theories. In the 2022 stratification essay, some responses knew functionalist, Marxist and feminist ideas but drifted away from the actual question. Keep returning each comparison to the claim you are evaluating.
Examiner hint: A reasoned judgement is stronger than a memorised criticism. Recent examiner reports emphasise weighing strengths and limitations and reaching a conclusion based on the argument developed in the essay.
Common Mistakes ⚠️
Mistake: Treating social differentiation and social stratification as identical
Why this is incorrect: Social differentiation identifies distinctions between social groups. Social stratification concerns structured inequality associated with social positions.
How to improve: Ask yourself whether the example merely shows that groups are different, or whether it also shows unequal resources, status, power or life chances.
Mistake: Assuming stratification only means social class
Why this is incorrect: AQA requires stratification and differentiation to be studied by social class, gender, ethnicity and age. Life chances must also be studied in relation to disability.
How to improve: Underline the particular social group or dimension named in the question before planning your answer.
Mistake: Reducing inequality to income
Why this is incorrect: The specification identifies class, status and power as dimensions of inequality and also requires study of differences in life chances.
How to improve: Consider whether the question involves resources, social standing, decision-making power or opportunities as well as economic differences.
Mistake: Describing a group without explaining the inequality
Why this is incorrect: Simply saying that two groups have different experiences does not show how stratification operates.
How to improve: Develop the chain: social group → unequal position → unequal resource or power → effect on life chances.
Mistake: Listing theories instead of evaluating them
Why this is incorrect: Examiner reports identify drift into general descriptions of perspectives as a weakness in stratification essays.
How to improve: Use each alternative perspective to answer the same debate. For example: "This challenges the functionalist explanation because..."
Exam-Style Questions ✍️
Questions
1. State one social characteristic by which AQA requires students to study stratification and differentiation.[1 mark]
2. State one dimension of inequality identified in the specification.[1 mark]
3. Explain the difference between social differentiation and social stratification.[4 marks]
4. A company employs people in several different occupational positions. Senior employees receive greater rewards and have more authority over workplace decisions than junior employees.
Explain how this situation illustrates both social differentiation and social stratification.[6 marks]
5. Read Item A and answer the question that follows.
Item A In a large organisation, employees occupy different occupational positions. Some positions provide greater economic rewards, while workers in senior positions also have greater control over decisions. Differences in people's experiences are also associated with gender and age.
Applying material from Item A, analyse two ways in which inequality may be organised within the organisation.[10 marks]
6. Outline and explain two ways in which social stratification may affect people's life chances.[10 marks]
7. Read Item B and answer the question that follows.
Item B Some sociologists argue that differences in rewards and social positions contribute to social order. Other sociologists argue that structured inequalities reflect conflicts between groups with different interests and unequal power.
Applying material from Item B, analyse two sociological explanations of the existence of social stratification.[10 marks]
8. Read Item C and answer the question that follows.
Item C Sociologists disagree about the significance of social stratification. Some argue that inequalities help organise society and contribute to social order. Others argue that stratification benefits some groups more than others and creates conflict. Inequalities may also be structured by several dimensions, including class and gender.

Mark Scheme
Question 1
Award 1 mark for any one of:
social class
gender
ethnicity
age
Question 2
Award 1 mark for any one of:
class
status
power
Question 3
Award up to 4 marks.
Indicative content:
Social differentiation refers to distinctions between social groups or categories.
Social stratification involves structured inequality between social groups.
A developed answer should make clear that stratification connects social differences to unequal position, resources, status, power or life chances.
A full-mark response should explain the distinction rather than simply provide two unrelated definitions.
Question 4
Award up to 6 marks for developed explanation.
Indicative content may include:
Different occupational positions illustrate social differentiation.
Unequal rewards demonstrate social stratification because the positions are associated with unequal advantages.
Unequal authority illustrates a difference in power.
The different positions may produce differences in status or life chances.
Higher-mark responses should make explicit links between the information in the scenario and sociological terminology.
Question 5
A strong answer should identify and develop two separate ways, explicitly using Item A.
Possible applications include:
Way 1: Unequal economic rewards
Item A states that some occupational positions receive greater economic rewards.
This illustrates stratification because occupational differences are associated with unequal resources.
These differences may then contribute to unequal life chances.
Way 2: Unequal power
Item A states that senior workers have greater control over decisions.
This shows that power is distributed unequally.
It demonstrates that stratification involves more than economic inequality.
An alternative developed point based on gender or age may also be credited.
For high marks, both points should use Item A and include analysis rather than description alone.
Question 6
Students should outline and explain two distinct ways.
Indicative content could include:
Social class inequality may create different opportunities in areas such as education, employment or health.
Differences in power or status may affect access to opportunities and social positions.
Inequalities based on gender, ethnicity, age or disability may affect life chances.
Restricted occupational opportunities may reduce opportunities for upward social mobility.
A strong answer develops two points clearly and explains the connection between stratification and life chances.
Question 7
Students should apply both parts of Item B.
Possible explanation 1:
Functionalist explanations may see stratification as contributing to social order.
Differences in rewards and positions may be connected to the organisation of social roles.
Shared values may encourage acceptance of the system.
Possible explanation 2:
Conflict explanations see stratification as reflecting unequal interests and unequal power.
Marxist explanations emphasise class divisions within capitalism.
The unequal structure may benefit one group more than another and produce conflict.
For higher marks, students should analyse the implications of each explanation rather than merely naming perspectives.
Question 8
This is an extended evaluative response.
A high-level answer should demonstrate:
accurate and detailed knowledge of sociological explanations of stratification
application of Item C
explicit comparison and evaluation
a sustained focus on whether inequality is mainly beneficial
a reasoned conclusion
Indicative arguments supporting the view may include:
functionalist explanations of stratification
the relationship between inequality, role allocation and social order
value consensus and acceptance of stratification
Indicative challenges may include:
Marxist explanations based on class inequality and conflict
unequal ownership, resources and power
the possibility that stratification benefits particular social groups rather than society as a whole
gender-based explanations showing that class is not the only important dimension of inequality
differences in life chances associated with several social divisions
For the highest marks, alternative perspectives should be used to evaluate the central claim, rather than being presented as separate descriptions. The conclusion should weigh the competing explanations and reach a justified judgement.
