The family is one of the most fundamental institutions in any society, yet it is also one of the most contested. For AQA A-Level Sociology (specification 7192), the opening unit of the Families and Households topic asks a deceptively simple question — what is a family? — and shows that the answer is anything but simple. How sociologists define the family, the range of family structures that exist, and the relationship between family form and wider social change are foundational issues that recur throughout the entire topic. The debate is never merely descriptive: every definition carries assumptions about what is "normal", and every claim about how the family has changed implies a theory of how families relate to the economy, the state and culture. This lesson establishes the concepts, named studies and arguments that underpin everything that follows.
Key Definition: A social institution is a relatively stable, organised set of social relationships and shared norms that meets a basic need of society. Treating the family as an institution means asking what it does for individuals and for the wider social structure — and asking who decides what counts as a "real" family in the first place.
This lesson addresses the opening content of the AQA A-Level Sociology (7192) specification, Paper 2 (Topics in Sociology), Section A — Families and Households:
The specification expects you to be able to describe (AO1) the main family types and the functional-fit thesis, apply (AO2) these to an Item, and evaluate (AO3) competing claims about whether industrialisation caused the shift to the nuclear family. Because Section A questions are drawn from this content, the conceptual vocabulary established here — nuclear, extended, household, kinship, functional fit, structural isolation — is assumed knowledge in every later lesson and in the 10- and 20-mark questions.
Before analysing the family sociologically, it is essential to distinguish two concepts that everyday language blurs: family and household.
Family: A group of people related by kinship — ties of blood (consanguinity), marriage, civil partnership, or adoption. Families typically involve mutual obligation, emotional bonds, and a shared identity that persists across residence and even across death.
Household: A person living alone, or a group of people who share a common residence, who may or may not be related. A household is a domestic and residential arrangement; a family is a set of relationships.
These concepts overlap but are not identical, and the gap between them is sociologically important. A group of students in shared accommodation forms a household but not a family. A non-resident father and his child remain a family but do not share a household. The rise of single-person households, Living Apart Together (LAT) couples, and transnational families whose members live in different countries all demonstrate that family relationships are not bounded by a single dwelling. The very difficulty of pinning the family down anticipates the personal life perspective (Smart, 2007), which argues that sociology should study relationships and meanings rather than residential units.
Sociologists identify several recurring family types. The following table summarises the main structures and shows why each matters for the diversity debate.
| Family Type | Definition | Significance |
|---|---|---|
| Nuclear family | Two generations — a married or cohabiting couple and their dependent children living together | Treated by functionalists and the New Right as the "ideal"; the benchmark against which other forms are judged |
| Extended family | The nuclear family plus additional kin — grandparents, aunts, uncles, cousins — living together or nearby and maintaining close ties | Central to the industrialisation debate (Parsons vs Laslett/Anderson) |
| Reconstituted (blended/step) family | A family in which one or both partners bring children from a previous relationship | Growing form created by high divorce and re-partnering; raises questions about "displaying" family (Finch) |
| Lone-parent family | A single parent (most commonly the mother) living with dependent children | The focus of New Right concern (Murray) and feminist defence |
| Same-sex family | A family headed by a same-sex couple, with children through adoption, surrogacy, donor conception, or previous relationships | Legally recognised since the 2000s; central to debates about whether family is biological or chosen |
| Beanpole family | A vertically extended but horizontally narrow family — several generations alive but few members in each | Product of longer life expectancy and lower fertility; studied by Brannen (2003) |
The classic extended family (also called the traditional extended family) is associated with pre-industrial Britain and with many traditional working-class communities into the twentieth century. It typically included three or more generations living under one roof or in close proximity, sharing economic production, childcare, and mutual support. Young and Willmott (1957) found a living version of this in their study of Bethnal Green, an established working-class district of East London, where married daughters maintained intense daily contact with their mothers, who provided childcare, advice and material help — the so-called "mum"-centred kinship network.
Peter Willmott (1988) argued that the extended family has not disappeared but has been modified. The modified extended family is one in which relatives are geographically dispersed yet maintain regular contact and exchange support through visits, telephone calls and money. Willmott's point is that geographical separation does not equal emotional or practical separation. Modern communication technology — video calls, messaging, social media — has, if anything, intensified the ability of dispersed kin to stay involved in one another's lives, a finding that fits Charles et al.'s (2008) Swansea research showing that the three-generation extended family remains a significant presence, especially among some minority-ethnic communities.
George Peter Murdock (1949) conducted a comparative survey of 250 societies and concluded that some form of the nuclear family was present in all of them — making it, in his view, a universal institution. He defined the family as:
"A social group characterised by common residence, economic cooperation, and reproduction. It includes adults of both sexes, at least two of whom maintain a socially approved sexual relationship, and one or more children, own or adopted, of the sexually cohabiting adults."
Murdock argued the nuclear family performs four essential functions:
| Criticism | Explanation |
|---|---|
| Ethnocentric | Murdock generalised from a Western, heterosexual nuclear model; his definition excludes same-sex families, lone-parent families and many non-Western forms |
| Ideological | Feminists (e.g. Oakley) argue it presents a rose-tinted image that ignores power inequalities, the "dark side" of domestic violence, and the exploitation of women's unpaid labour |
| Outdated | Family forms have diversified enormously since 1949; cohabiting couples, reconstituted and child-free couples do not fit |
| The Nayar | Kathleen Gough (1959) studied the Nayar of Kerala, India, where women had multiple "visiting husbands" (sambandham partners) and children were raised within the mother's matrilineal kin group, not a nuclear family — directly challenging universality |
A central, examinable debate concerns how the family changed with industrialisation — and whether industrialisation caused that change.
Before industrialisation (roughly pre-1750 in Britain), most families were units of production: members worked together on the land or in domestic ("cottage") industry. On the classic account the extended family was common, with generations pooling labour and resources, and children were economic assets contributing to family income early.
Peter Laslett (1972), using parish records, challenged this picture. He found that the nuclear family was in fact the most common household structure in pre-industrial England from the 1500s, with an average household size of only about 4.75 persons. Laslett argued that high adult mortality and late marriage meant few people lived long enough to form three-generation households. If the nuclear family pre-dated the Industrial Revolution, then industrialisation cannot have created it.
Talcott Parsons (1955) argued that family structure changes to "fit" the needs of the wider society. He proposed a historical shift driven by the demands of the economy:
| Era | Dominant Family Type | Reason |
|---|---|---|
| Pre-industrial society | Extended family | The family was a unit of production; kin networks provided welfare, labour and mutual support |
| Industrial society | Isolated nuclear family | Industry needs a geographically mobile workforce that moves to where jobs are; the smaller nuclear unit is more mobile. Industrial society also rests on achieved status (meritocracy) rather than ascribed status, reducing the pull of wider kin ties and avoiding status conflict between the man's family role and his occupational role |
Parsons called the result the structural isolation of the nuclear family: cut off from wider kin, the nuclear unit becomes self-contained, relying on the state and the market — not on the extended family — for welfare and support. The functions it loses to specialised institutions (production, education, healthcare) leave it, in Parsons' later analysis, with two irreducible functions: the primary socialisation of children and the stabilisation of adult personalities (the "warm bath").

The upshot is that the relationship between family form and the economy is two-way and uneven, not a single tidy transition from extended to nuclear.
Family structures vary enormously across cultures, undermining any straightforward claim of universality.
In Israeli kibbutzim (collective agricultural communities), children were historically raised communally in children's houses rather than by individual nuclear families. Childcare, education and socialisation were collective responsibilities, challenging the assumption that the nuclear family is necessary for rearing children (though many kibbutzim later moved back towards family-based child-rearing).
As noted, Gough (1959) described a system in which the nuclear family did not exist in Murdock's sense. Nayar women took multiple visiting husbands, and children were raised within the mother's taravad (matrilineal kin group); the biological father had no enduring social role.
In some societies polygyny (one husband, several wives) is practised, for example in parts of West Africa and among some communities elsewhere. Polyandry (one wife, several husbands) is rarer but documented among the Toda of southern India and in parts of the Himalayas. Both challenge the Western equation of "family" with the monogamous couple.
In parts of the Caribbean, matrifocal (female-headed) households are common, with mothers and grandmothers central to child-rearing and fathers sometimes peripheral. Mary Chamberlain (1999) argued that such families should be understood on their own terms — as "multiple nuclear families" linked through extensive, supportive kin networks — rather than judged as deficient against a Western nuclear norm.
A closely related debate concerns whether the family has lost functions as society modernised, or merely changed them. Functionalists such as Parsons argue for a "loss of functions": pre-industrial families produced goods, educated children, nursed the sick and cared for the old, whereas modern families have surrendered these tasks to the factory, the school, the NHS and the welfare state, retaining only socialisation and the stabilisation of adult personalities. Ronald Fletcher (1966), however, took a more optimistic functionalist view, arguing that the family has not so much lost functions as seen them intensify and specialise. Parents, he argued, are now more involved in supporting their children's education and health than ever before, and the family remains a vital unit of consumption whose members work to provide a home, a car and holidays. The disagreement matters because it shapes how we read family change: as decline (a thinning institution that has handed its work to the state) or as adaptation (a re-tooled institution doing fewer things more intensively). Conflict theorists reply that both functionalist readings ignore the unequal distribution of these functions: it is overwhelmingly women who absorb the intensified caring, domestic and emotional work, a point developed in the lessons on domestic labour and on feminism. The "loss of functions" debate therefore connects the abstract question of family structure to the concrete, gendered reality of who actually performs the family's tasks.
The relationship between family form and social change is also visible in the changing internal organisation of the family. Elizabeth Bott (1957) distinguished segregated conjugal roles (clearly separated "his and hers" tasks and leisure) from joint conjugal roles (shared tasks, leisure and decisions), and linked role segregation to the dense, single-sex social networks of close-knit working-class communities such as Young and Willmott's Bethnal Green. As nineteenth-century industrial cities gave way to twentieth-century suburban estates, and as geographical mobility loosened those tight networks, Young and Willmott (1973) argued the family became privatised and increasingly symmetrical — home-centred, nuclear, and (they claimed) more equal in its conjugal roles. Whether this "march of progress" towards symmetry actually occurred is fiercely contested by Oakley and later feminists, who argue it overstated men's domestic contribution. But the direction of the argument illustrates this lesson's central theme: changes in the wider social structure (urbanisation, mobility, the labour market, women's employment) reshape not only which family type predominates but how family members relate within it. This is precisely why the specification's "structure and social change" bullet cannot be divorced from the later bullets on gender roles, domestic labour and power relationships — the macro-level structure and the micro-level relationship are two sides of the same process.
Murdock provides a clear, comparative starting point, but his definition is ethnocentric. Surveying 250 societies gives the universality claim apparent empirical weight, and a precise definition is testable. However, the very cases that test it — the Nayar (Gough), matrifocal Caribbean households (Chamberlain), same-sex families — fall outside it, so the definition functions less as neutral description than as a normative model of what Murdock assumed a family should be.
Parsons offers a powerful explanation for the dominance of the nuclear family, but the historical timeline is wrong. The functional-fit thesis elegantly links family form to the needs of an industrial economy (mobility, achieved status). Yet Laslett's parish records show the nuclear family pre-dated industry, and Anderson's Preston data show extended kin grew in the early factory period — so the causal story is at best incomplete. The reasonable inference is that the family adapts to economic conditions in complex, two-way ways rather than by a single functional switch.
Cross-cultural and historical evidence demonstrates real diversity, but risks relativism. Recognising the Nayar, the kibbutz, polygamy and matrifocal families guards against ethnocentrism and shows the family is shaped by economy, religion and culture. The danger is cultural relativism — if every arrangement is simply "different", sociology loses any basis for asking whether particular forms serve children's or women's interests, a question feminists insist must be kept open.
Postmodern and personal-life critiques argue that defining "the family" at all is misguided. Smart (2007) contends that imposing a top-down definition excludes the relationships that matter most to people. This is an important corrective, but, as Marxists and feminists reply, abandoning structural definitions can obscure the persistent patterns of class and gender inequality that still shape family life — so the most defensible position retains structural analysis while remaining alert to meaning and diversity.
The functionalist "loss of functions" thesis captures real change but is contested even within functionalism. Parsons' claim that the family has shed functions to specialised institutions plausibly describes the transfer of production, formal education and healthcare. Yet Fletcher (1966) shows the same evidence can be read as intensification rather than loss, and conflict theorists show that whichever reading is correct, it is silent on the gendered distribution of the family's remaining work. The reasonable conclusion is that the family's relationship to the social structure is one of continuous adaptation — neither a simple decline nor a frictionless functional fit — and that any adequate account must specify not just what the family does but who within it does it.
Item A
Sociologists disagree about how far the structure of the family is shaped by the wider society. Some argue that the family changes to "fit" the needs of the economy: as Britain industrialised, the geographically mobile nuclear family is said to have replaced the extended family. Others point to historical evidence suggesting that the nuclear family existed long before industrialisation, and that extended kin ties remained important during the early factory period.
Applying material from Item A, analyse two ways in which the structure of the family may be shaped by economic change. (10 marks)
AO breakdown: this question is marked for AO1 (knowledge of two relevant points), AO2 (application — both points must be "hooked" to the Item), and AO3 (analysis — developing each point logically). There are no marks for a long evaluation here; the skill is selecting two distinct, Item-anchored points and developing each in a tight paragraph. Strong responses lift a phrase from the Item ("changes to fit the needs of the economy"; "existed long before industrialisation") and build a developed chain of reasoning from it.
Item B
Functionalist sociologists argue that the nuclear family is the family form best suited to modern industrial society, performing essential functions for individuals and for the social structure. Critics, however, argue that this view exaggerates the dominance of the nuclear family, ignores the diversity of family life across cultures and history, and treats one culturally specific arrangement as if it were universal and natural.
Applying material from Item B and your knowledge, evaluate the view that the structure of the family is shaped above all by the needs of the wider society. (20 marks)
AO breakdown: on Paper 2 the 20-mark essay is marked AO1 (≈8) for knowledge, AO2 (≈4) for sustained application to the Item, and AO3 (≈8) for evaluation. (Note: Paper 2 essays are 20 marks, not 30.) AO1 requires Parsons' functional-fit and irreducible-functions argument plus Murdock; AO2 requires repeated explicit engagement with the Item's two sides (functionalist optimism vs the diversity critique); AO3 requires Laslett, Anderson, cross-cultural evidence and the personal-life critique, reaching a substantiated judgement.
Mid-band response:
Functionalists like Parsons say the nuclear family fits modern society. As the Item says, it performs essential functions. Parsons argued that in industrial society you need a mobile workforce, so the small nuclear family is better than the extended family because it can move to where the jobs are. Society is also based on achieved status now, so people get jobs on merit rather than through family connections. Murdock also said the family is universal and does four functions: sexual, reproductive, economic and educational. This supports the idea that the family is shaped by the needs of society.
However, other sociologists disagree. Laslett used parish records and found the nuclear family existed before industrialisation, so industry did not cause it. Anderson found extended families in Preston. There is also lots of diversity, like the Nayar studied by Gough, and same-sex families today. This shows the family is not always nuclear. Overall, the family is partly shaped by society but there is also a lot of diversity, so the functionalist view is too simple.
Stronger response:
The view in Item B is essentially Parsons' (1955) functional-fit theory: family structure adapts to the needs of the wider social structure. Parsons argued that pre-industrial society suited the extended family because the family was a unit of production and kin provided welfare, whereas industrial society requires a geographically mobile workforce and rests on achieved status, both of which favour the isolated nuclear family. Stripped of its older functions, the nuclear family retains two irreducible functions — primary socialisation and the stabilisation of adult personalities (the "warm bath"). Murdock (1949) reinforces the "needs of society" emphasis, claiming the nuclear family is universal because it meets four functional prerequisites. Applied to the Item, this is the functionalist case that one family form is best fitted to industrial society.
However, the Item also signals the critics, and the historical evidence is damaging. Laslett (1972), using parish records, found the nuclear family was already the dominant household in pre-industrial England, with an average size of about 4.75 — so industrialisation cannot have produced it. Anderson (1971), using 1851 census data for Preston, found extended kin networks increased during early industrialisation as workers pooled resources. Cross-cultural evidence (Gough's Nayar; matrifocal Caribbean families, Chamberlain 1999) further undermines the claim that the nuclear form is universal or natural. The most defensible conclusion is that economic structure shapes family form, but not in the single, tidy way Parsons implied: the relationship is two-way and mediated by culture and policy, so the view is partly right but overstated.
Top-band response:
Item B counterposes the functionalist claim that the nuclear family is uniquely "fitted" to industrial society against the critique that this universalises one culturally specific form. The functionalist case is strongest when stated precisely. Parsons (1955) argues that the needs of the social structure select family form: industrial production demands a geographically mobile workforce, so the structurally isolated nuclear family — detachable from wider kin — is functionally advantageous, while a shift from ascribed to achieved status removes the friction between family obligation and occupational role. The family that survives this transition specialises in two irreducible functions, primary socialisation and the stabilisation of adult personalities. Murdock's (1949) survey of 250 societies supplies the universality premise. So far the Item's first sentence is well supported: family structure does appear responsive to economic structure.
The evaluative weight, however, falls the other way, and the discriminating skill is to show why. Laslett's (1972) parish-record evidence that the nuclear household pre-dated industrialisation is not a minor caveat but a refutation of the causal claim: if the explanandum existed before the supposed cause, the functional-fit timeline collapses. Anderson's (1851 Preston) finding that extended kin intensified in the early factory period inverts the prediction entirely, suggesting the family adapts to economic conditions through whatever form best manages risk — extended when insurance against hardship is needed, nuclear when mobility is at a premium. This already reframes the question: the family is shaped by economic conditions, but it is the direction of fit that Parsons mis-specified. Cross-cultural evidence (Gough's matrilineal Nayar; Chamberlain's matrifocal Caribbean networks) then dismantles the universality premise, exposing functionalism's ethnocentrism, while Smart's (2007) personal-life perspective argues the whole project of defining "the family" by structure misses the meanings people actually live by. Yet the Marxist and feminist reply to Smart — that abandoning structural analysis hides persistent class and gender inequality — cautions against discarding the "needs of society" lens altogether. The judicious conclusion is therefore neither functionalist nor purely postmodern: family structure is powerfully conditioned by the economy and by state policy and culture, in a reciprocal relationship that no single-cause "functional fit" can capture. The view in the Item is thus a genuine insight that has been overstated into an error.
The Mid-band answer shows accurate but underdeveloped knowledge: Parsons, Murdock, Laslett and Anderson are all present and the two sides of the Item are recognised, but points are listed rather than explained, application to the Item is implicit, and the conclusion ("too simple") is asserted rather than reasoned. It would sit in the middle band for AO1 and AO3 with limited AO2. The Stronger answer adds precise content (the mobility/achieved-status mechanism, the two irreducible functions, the 4.75 household size, the 1851 Preston data) and, crucially, explains why Laslett's evidence damages the causal claim, reaching a measured "two-way relationship" judgement that lifts it towards the top of the band. The Top-band answer demonstrates the discriminating features examiners reward: it organises the essay around the Item's opposition, prioritises evaluation by distinguishing the direction of fit from the fact of fit, integrates the personal-life critique and its Marxist/feminist counter, and reaches a synthesised judgement rather than a list. Throughout, the Item is woven in explicitly (AO2) and perspectives are treated as objects of analysis, which is exactly what is expected.
This content is aligned with the AQA A-Level Sociology (7192) specification.
