O Level Sociology: Types of Family and How Family Life Is Changing (Cambridge 2251)

Families take many forms, and they are changing quickly almost everywhere. Key questions 4.1 (What are the different types of families?) and 4.3 (How is family life changing?) of Cambridge O Level Sociology (2251) cover family structures, diversity, alternatives to the family and types of marriage, then demographic change, industrialisation and urbanisation, trends in marriage, divorce and cohabitation, and changing roles of partners, children and grandparents.

The role of the family (4.2) is covered in the O Level family, education and crime guide.

Syllabus coverage

Cambridge O Level Sociology 2251 (2025–2027), topic 4 Family:

• 4.1 — 4.1.1 family structures (nuclear; extended, e.g. modified, horizontal, vertical/beanpole; reconstituted; lone parent; empty nest; childless) and their strengths and limitations; 4.1.2 variations by culture, social class and ethnicity; 4.1.3 New Right and postmodernist views of diversity and the dominance of the nuclear family; 4.1.4 alternatives (single-person households, shared households, friends as family); 4.1.5 types of marriage (arranged, empty shell, love, monogamy, serial monogamy).
• 4.3 — 4.3.1 demographic factors (family size, birth rates, life expectancy, ageing population, having children later); 4.3.2 industrialisation and urbanisation; 4.3.3 explanations of trends in marriage, divorce and cohabitation (legislation, attitudes and values, the internet, secularisation, cultural expectations, female empowerment); 4.3.4 alternatives to marriage; 4.3.5 changing conjugal roles, roles of children and roles of grandparents.

The syllabus notes that some family and marriage types (for example polygamous or same-sex families) may be taught where appropriate locally but are not assessed.

What family structures are there?

Structure	Description	Strength	Limitation
Nuclear	Two parents and their children	Mobile; close emotional ties	Isolated from wider kin support
Extended — horizontal	Includes siblings, cousins or in-laws of the same generation	Shared income and childcare	Less privacy; possible conflict
Extended — vertical / beanpole	Several generations, few members in each (Brannen, 2003)	Grandparents help with childcare	Middle generation may care for both young and old
Modified extended	Relatives live apart but keep frequent contact	Support without crowding	Depends on transport and communication
Reconstituted	Step-family formed after divorce or death	A second chance at family life	Adjustment and loyalty conflicts
Lone parent	One parent with dependent children	Can avoid conflict of an unhappy marriage	Higher risk of poverty
Empty nest	Couple whose children have left home	Freedom and time	Loneliness, loss of role
Childless	Couple without children, by choice or not	Resources and time	Social pressure in pro-natalist cultures

In much of South Asia the joint family — several brothers, their wives and children living with their parents — has been a traditional form of extended family.

How do families vary?

The Rapoports (1982) identified dimensions of family diversity. Three are named in 2251:

• Cross-cultural — expectations about marriage, residence and authority differ between societies.
• Social class — resources shape family life; middle-class families may move for careers, while working-class families have often relied on local kin networks.
• Ethnicity — migrant families may keep extended-family traditions or adapt to local norms.

Do sociologists welcome family diversity?

• New Right: the married two-parent nuclear family is best for children and society; lone-parent and other “non-traditional” families are linked to poor socialisation and dysfunctional families.
• Postmodernists: diversity is positive — people choose relationships that suit them. Judith Stacey (Brave New Families, 1990) described women creating new family forms after divorce.
• How dominant is the nuclear family? Robert Chester (1985) argued most people still spend part of their lives in a nuclear family, often a “neo-conventional” one where both partners work.

What are the alternatives to the family and types of marriage?

Alternatives (4.1.4): single-person households; shared households (for example students or young workers); friends as family.

Types of marriage (4.1.5):

• Arranged — families choose or help choose partners; common in South Asia.
• Love — partners choose each other based on romantic attraction.
• Empty shell — a marriage that continues in name, without love, often for children, money or reputation.
• Monogamy — one spouse at a time; serial monogamy — a series of monogamous marriages after divorce or death.

How are demographic changes affecting families? (4.3.1)

• Smaller families — falling birth rates due to contraception, cost of children and women’s education and careers.
• Longer life expectancy and an ageing population — more grandparents and great-grandparents; beanpole families.
• Having children later — longer education and careers delay parenthood.

Did industrialisation create the nuclear family? (4.3.2)

Talcott Parsons argued the isolated nuclear family “fits” industrial society because it is geographically mobile. Historians challenged this: Peter Laslett (1972) found nuclear households were already common in pre-industrial England, and Michael Anderson’s study of the 1851 census for Preston (1971) found working-class families sharing homes with relatives to cope with industrial hardship. Urbanisation has also moved families from villages to cities, weakening some kin ties while others continue through visits and phones.

Why are marriage, divorce and cohabitation changing? (4.3.3 and 4.3.4)

Explanation	Example of effect
Legislation	Laws making divorce easier or giving women rights in divorce — e.g. Pakistan’s Muslim Family Laws Ordinance (1961) regulated marriage registration and divorce
Societal attitudes and values	Less stigma attached to divorce and cohabitation in many societies
Role of the internet	Online matchmaking and dating apps widen partner choice
Secularisation	Declining religious influence reduces pressure to marry or stay married
Cultural expectations	Some cultures still expect early, arranged marriage
Female empowerment	Women’s education and income mean they can leave unhappy marriages

Alternatives to marriage: cohabitation, singlehood, lone parenthood and, where legal, civil partnerships.

How are family roles changing? (4.3.5)

• Conjugal roles — a move from segregated to more joint roles. Peter Willmott and Michael Young’s The Symmetrical Family (1973) described couples sharing tasks and decisions; feminists found women still did most domestic work. Dual-worker families are now common. The pivot or sandwich generation cares for both children and elderly parents.
• Children — once an economic asset, children are now an economic cost; families have become more child-centred; boomerang children return home as adults because of housing costs or unemployment.
• Grandparents — provide childcare, economic support and wisdom and advice; some become dependent and need care.

Frequently asked questions

What is a beanpole family? A vertically extended family with several generations alive at once but few members in each, caused by longer life expectancy and lower birth rates.

Is the nuclear family disappearing? No — it remains common, but more people now live in other family types at some stage of life.

Why is divorce rising in many societies? Easier laws, changing attitudes, secularisation and women’s greater independence are the main explanations.
