Anthropologists have explained stability and change in the family through several models. The evolutionary model (Morgan) arranged family forms in stages from promiscuity to monogamy. The functional model (Malinowski, Radcliffe-Brown) explained stability through the needs the family meets. The disintegration model held that industrialization breaks down the family. The adaptation model (Laslett, Firth, Singer) showed that families adapt and that nuclear households existed long before industry. The cyclical model (Fortes) treated variation as phases in a developmental cycle. Jack Goody linked family forms to how property is transmitted (bridewealth versus dowry), and Marshall Sahlins linked them to the mode of production (the domestic mode of production). Each model explains part of the picture; no single one explains it all.
This note explains the concepts of stability and change in the family and the seven main models used to explain them, with their strengths and criticisms, for the UPSC Anthropology Optional. It belongs to Paper I, topic 2.4 (Family) in the Anthropology Optional syllabus.
Key points at a glance
- Stability: a steady state, or functional equilibrium, among the parts of the family.
- Change: transformation of the family under internal or external forces, usually gradual, passing through disequilibrium to a new adjustment.
- Evolutionary model: Lewis Henry Morgan's five stages: consanguine, punaluan, syndyasmian, patriarchal and monogamian families.
- Functional model: Malinowski (needs) and Radcliffe-Brown (structural equilibrium); explains stability but not change.
- Disintegration model: industrialization, urbanization and individualism weaken the family (Ogburn, Zimmerman, Leach).
- Adaptation model: families adapt; nuclear households were common before industrialization (Laslett, Firth, Levy, Singer).
- Cyclical model: family forms are phases of a developmental cycle (Fortes: expansion, dispersion, replacement).
- Goody's property-transmission model: bridewealth goes with polygyny and unilineal descent; dowry with monogamy and bilateral tendencies.
- Sahlins' mode-of-production model: the family is autonomous under the domestic mode of production and loses autonomy as kinship and politics demand surplus.
What are stability and change?
Stability means a steady state: a functional equilibrium among the internal parts of the family, such as its roles, relationships and activities, which fit together and support one another.
Change is the process by which the family is transformed or modified when it is subjected to internal factors (such as birth, death, marriage and conflict) or external factors (such as economic, legal and cultural change). Change is usually gradual rather than sudden. A family under pressure may pass through a period of disequilibrium, after which it adapts to the new circumstances and reaches a new equilibrium.

1. The evolutionary model
Nineteenth-century anthropologists, including J. J. Bachofen (Das Mutterrecht, 1861), J. F. McLennan (Primitive Marriage, 1865), John Lubbock, E. B. Tylor and above all Lewis Henry Morgan (Ancient Society, 1877), believed that human society had progressed through fixed stages. They imagined an earliest stage of sexual promiscuity, with no marriage and no family. Later, people came to see the economic and social advantages of more permanent sexual relations, and the family evolved towards monogamy.
Morgan linked five forms of family to his three "ethnical periods": savagery, barbarism and civilisation.
| Stage | Form | Period |
|---|---|---|
| 1. Consanguine family | Group marriage of brothers and sisters, own and collateral, within a group | Savagery |
| 2. Punaluan family | Group marriage of several brothers to each other's wives, or several sisters to each other's husbands, the partners not being brother and sister | Savagery |
| 3. Syndyasmian (pairing) family | Marriage of single pairs, which either partner could end at will; no exclusive cohabitation | Barbarism |
| 4. Patriarchal family | Marriage of one man to several wives under the authority of the father, as among the ancient Hebrews and pastoral peoples | Barbarism, with herding and agriculture |
| 5. Monogamian family | Marriage of one man and one woman with exclusive cohabitation | Civilisation |
Friedrich Engels (The Origin of the Family, Private Property and the State, 1884) built on Morgan, arguing that monogamy arose with private property, so that men could pass property to their own children.
Criticism
- There is no ethnographic evidence that any society ever practised general promiscuity or group marriage of brothers and sisters. Morgan inferred the consanguine family mainly from Hawaiian kinship terms, which can be explained in other ways.
- Edvard Westermarck (The History of Human Marriage, 1891) argued that pair-bonding and the family were present from the beginning.
- Franz Boas, Robert Lowie and others rejected unilinear evolution as speculative and ethnocentric, because it placed Victorian monogamy at the top.
- The model describes stages but does not explain the mechanism of change in any particular society.
2. The functional model
Functionalists such as Bronisław Malinowski and A. R. Radcliffe-Brown presented an equilibrium model of the family, emphasising its stability.
Malinowski saw the family as a cultural institution that arose in response to basic biological and psychological needs: sex, reproduction, the care of children and security. He argued that it is found universally, and that it not only satisfies these needs but also contributes to the maintenance and continuity of the whole culture. His "principle of legitimacy" held that every society requires a child to have a socially recognised father.
Radcliffe-Brown saw the family as a social group in a state of structural-functional equilibrium. In this group children are born, raised and educated. It is held together by strong bonds of affinity (marriage) and consanguinity (blood), filiation (parent and child) and fraternity (siblings), and by kinship obligations. All parts of the family work together with enough harmony and internal consistency to create "social equilibrium", a state in which all parts are integrated and contribute to order and stability.
Talcott Parsons later extended this view, arguing that the nuclear family specialises in the primary socialisation of children and the emotional stabilisation of adults.
Criticism
- The model explains stability but not change, because it assumes that every part contributes to equilibrium.
- It overlooks conflict, inequality and violence within the family.
- It tends to treat existing family forms as necessary.
3. The disintegration model
Studies of the impact of industrialization, urbanization, modern education, women's movements and secularisation on the family led many scholars to argue that the family was disintegrating. Power-driven machines replaced hand tools; secondary associations and state agencies took over the family's functions; modern education spread democratic and individualistic values that undermined authoritarian, feudal customs; and the status and rights of women changed. The main effects described are:
- Weaker kinship: frequent physical and social mobility loosens family and kinship ties. Relations continue, but their warmth, intimacy and mutual obligation decline.
- Family disorganisation: ties of kinship weaken, and so do psychological ties. The nuclear family may fail to meet the emotional needs of its members, under pressures such as both spouses working, fatigue and material strain. Separation and divorce follow.
- Mate selection: individualism replaces arranged marriage by kin with marriage by personal choice, and the ceremony of marriage becomes increasingly secular.
- Loss of production: the family ceases to be a unit of production and becomes mainly a unit of consumption (W. F. Ogburn's "loss of functions").
- Outside agencies: schools, hospitals and social security take over educational, health and welfare functions. Children learn knowledge their parents do not share, so tension between generations increases.
Edmund Leach, in his BBC Reith Lectures (A Runaway World?, 1967), argued that the isolated nuclear family turns inward on itself and suffers intense emotional stress between husband and wife and between parents and children. His argument is often summed up by the image of an overloaded electrical circuit that blows a fuse: the parents fight and the children rebel. He famously said that "far from being the basis of the good society, the family, with its narrow privacy and tawdry secrets, is the source of all our discontents."
Carle Zimmerman (Family and Civilization, 1947) argued that Western civilisation had moved from the strong "trustee" family to the weak "atomistic" family, a sign of social decline. Some writers predicted that rising cohabitation, births outside marriage and single motherhood would make the mother-child unit the basic family of highly industrial societies.
Criticism
- The model assumes a stable, extended pre-industrial family, which historical research has not confirmed.
- It treats change as breakdown rather than adaptation, and often reflects moral anxiety rather than evidence.
- Most people still marry or form couples, have children and maintain kin ties.
4. The adaptation model
Marion Levy, Milton Singer, Raymond Firth, Peter Laslett and others challenged the disintegration model. Earlier scholars had assumed that the modern nuclear family was an innovation produced by industrialization, and that the extended, three-generation family had been the norm before it. Research showed otherwise.
- Nuclear households are old: Peter Laslett and the Cambridge Group showed that nuclear households predominated in north-western Europe for at least three centuries before industrialization. Only about 10 per cent of English households between 1574 and 1821 were extended. Industrialization therefore did not destroy a traditional extended family.
- The ideal and the actual: Marion Levy (1965) argued that in all societies, whatever their ideal, most people actually live in small households, because mortality and fertility limit how many generations and relatives can live together.
- Family versus household: a critical distinction was made between family and household. The family includes only kin, while the household may also include non-kin such as servants, apprentices and lodgers. In pre-industrial England, many young people lived as "life-cycle servants" in other households.
- The household as a flexible unit: the household continued to function as an economic unit even after losing its role in production, pooling wages and resources. It expanded and contracted with the family's needs, taking in kin or lodgers in hard times. Michael Anderson (1971) found that in 19th-century Preston, industrial workers took in kin more often than before.
- Kin as social security: before the welfare state, kin networks were the main source of social security.
- Kinship survives migration: kin ties continue during migration and help people adapt to new environments. Raymond Firth (Two Studies of Kinship in London, 1956) found active kin ties in London, and Eugene Litwak described the "modified extended family".
- India: Milton Singer (1968) showed that Madras industrialists adapted the joint family to run modern firms. I. P. Desai, K. M. Kapadia and A. M. Shah showed that Indian families remain functionally joint despite nuclear residence.
Criticism
- The model may understate real changes, such as rising divorce, declining fertility and changing gender roles.
- Laslett's findings apply mainly to north-western Europe; other regions, such as eastern Europe and Asia, had more complex households.
5. The cyclical model
The cyclical model treats the family as a process: a series of recurring stages linked to the changing needs of individuals at different points in life.
Life-course stages
Some anthropologists describe the stages of an individual's relation to the family as:
- Formative stage: the child is prepared to become a responsible member of society.
- Pre-nuptial stage: the adolescent prepares psychologically for married life and parenthood. In many tribal societies, youth dormitories such as the Muria ghotul provide a kind of rehearsal for adult roles. In societies with child marriage and arranged marriage, this stage may scarcely exist.
- Post-nuptial stage: the individual marries, has children and concentrates on the family of procreation without wholly cutting ties with the family of orientation. This stage matters most for the reproduction of society.
The family is stable within each stage and changes in the transition to the next, until it completes the cycle and a new cycle begins.
Fortes' developmental cycle
Meyer Fortes (in The Developmental Cycle in Domestic Groups, edited by Jack Goody, 1958) argued that variations in family organisation within a society, at any given time, are often different phases of the developmental cycle of a single general form. He described three phases:
| Phase | Begins | Ends |
|---|---|---|
| Expansion | Marriage of a couple | Completion of their family of procreation; children remain dependent on the parents |
| Dispersion or fission | Marriage of the eldest child | Marriage of the youngest child; usually one child (the heir) remains in the parental home |
| Replacement | Ageing of the parents | Death of the parents and their replacement in the social structure by the family of one of their children |
Each phase is stable while it lasts, and change occurs in the passage from one phase to the next. When the cycle is complete, it begins again: stability and change are both part of a continuing process. In India, Pauline Kolenda and T. N. Madan showed that the Hindu family moves through nuclear and joint phases in this way.
Carle Zimmerman offered a different, historical cyclical model: civilisations move from the "trustee" family (strong, extended, with authority over members) to the "domestic" family (balanced between family and individual) to the "atomistic" family (weak, individualistic), after which civilisation declines and the cycle may begin again.
Criticism
- Cyclical models do not explain every kind of variation in family forms. They ignore demographic and historical processes that can produce lasting change.
- A society may have not one but several ideal family types, since different groups or classes have different ideals and practices and are affected differently by social change.
6. Goody's property-transmission model
Jack Goody (Bridewealth and Dowry, with S. J. Tambiah, 1973; Production and Reproduction, 1976) linked a cluster of factors, namely marriage payments, descent groups, kinship terminology and family organisation, to the ways property is transmitted between generations ("devolution"). He in turn related these to differences in agriculture.
| Feature | Sub-Saharan Africa pattern | Eurasian pattern |
|---|---|---|
| Agriculture | Hoe agriculture; land plentiful | Plough agriculture; land scarce and valuable |
| Property transmission | Homogeneous: property passes to members of the same sex and lineage | Diverging devolution: property passes to both sons and daughters |
| Marriage payment | Bridewealth, paid by the groom's kin to the bride's kin | Dowry, given to the bride as her share of family property |
| Marriage form | Polygyny common | Monogamy |
| Descent | Unilineal descent groups strong | Bilateral tendencies; the nuclear family stands out |
| Social structure | Less stratified | Stratified; families control daughters' marriages to keep property within their class (endogamy) |
For Goody, bridewealth and dowry are not just marriage gifts but ways of redistributing property, and they shape kinship relations and family form. Stability or change in the family depends on how property is transmitted, and that depends on the mode of agriculture and the scarcity of land. In The Development of the Family and Marriage in Europe (1983), Goody argued that the medieval Church's bans on cousin marriage, adoption and remarriage of widows reduced the number of heirs and helped the Church acquire property, reshaping the European family.
India fits the Eurasian pattern: plough agriculture, scarce land, caste stratification, dowry, and an emphasis on endogamy. Bride price persists in many tribal communities, which are closer to the African pattern.
Criticism
- The contrast between Africa and Eurasia is broad and has many exceptions.
- Dowry and bridewealth have complex meanings that cannot be reduced to property.
7. Sahlins' mode-of-production model
Marshall Sahlins (Stone Age Economics, 1972), drawing on Karl Marx and the Russian economist A. V. Chayanov, argued that the organisation of production, rather than property transmission, determines family organisation. He described a "domestic mode of production" (DMP).
| Domestic mode of production (simple societies) | Extra-domestic production (complex societies) |
|---|---|
| The household produces what it needs, using its own labour | Kinship ties and political relations link households and limit their autonomy |
| Production is limited to the household's requirements | Kinship obligations, feasting and chiefs or "big men" stimulate production of a surplus |
| Once needs are met, there is no stimulus to produce more ("underproduction"; Chayanov's rule that work intensity varies with the ratio of consumers to workers) | Extra-domestic groups, such as lineages, chiefdoms and the state, become economic units |
| The household acts as an autonomous economic and political unit | The domestic mode of production is overridden |
According to Sahlins, the family was stable when it was tied to the domestic mode of production. Change occurred when kinship, chiefship and later the state drew households into wider systems of production and exchange, which demanded surplus and reduced household autonomy. Sahlins' model has been influential in economic anthropology, though critics argue that "underproduction" partly reflects the limits of the data.
Comparing the models
| Model | Explains stability? | Explains change? | Main weakness |
|---|---|---|---|
| Evolutionary | No | As fixed stages | Speculative and ethnocentric |
| Functional | Yes | Poorly | Ignores conflict and change |
| Disintegration | No | As breakdown | Assumes a mythical stable past |
| Adaptation | Yes, through flexibility | As adjustment | May underplay real change |
| Cyclical | Within phases | Between phases | Ignores historical change |
| Goody | Through stable property systems | When property systems change | Over-broad regional contrasts |
| Sahlins | Under the domestic mode | When production becomes extra-domestic | Limited to simple economies |
The models are complementary. The functional and cyclical models explain stability and short-term variation; the adaptation model explains how families cope with industrial change; and Goody and Sahlins explain long-term change through property and production.

Frequently asked questions
What are the models of stability and change in the family?
The main models are the evolutionary model (Morgan), the functional model (Malinowski, Radcliffe-Brown), the disintegration model (Ogburn, Zimmerman, Leach), the adaptation model (Laslett, Firth, Singer), the cyclical model (Fortes), Goody's property-transmission model and Sahlins' mode-of-production model.
What are Morgan's stages of the family?
Lewis Henry Morgan (1877) proposed five stages: the consanguine family, the punaluan family, the syndyasmian or pairing family, the patriarchal family and the monogamian family, linked to savagery, barbarism and civilisation.
Why does the functional model fail to explain change?
Because it assumes that every part of the family contributes to equilibrium and stability, so it has no place for the conflict and disequilibrium that produce change.
What is the disintegration model of the family?
The view that industrialization, urbanization, individualism and secularisation weaken kinship ties, strip the family of its functions and lead to divorce and family breakdown. Edmund Leach described the isolated nuclear family as under intense emotional strain.
What is the adaptation model of the family?
The view that the family adapts flexibly to social change. Peter Laslett showed that nuclear households predominated in pre-industrial England, so industrialization did not create the nuclear family, and studies show that kin ties persist and help people adapt to new environments.
What are Fortes' three phases of the developmental cycle?
Expansion (from marriage to the completion of the family of procreation), dispersion or fission (from the marriage of the first child to that of the last), and replacement (ending with the death of the parents and their replacement by the family of a child).
What is Goody's model of bridewealth and dowry?
Jack Goody linked bridewealth, polygyny and unilineal descent to hoe agriculture and plentiful land in Africa, and dowry, monogamy and diverging devolution of property to plough agriculture, scarce land and stratification in Eurasia.
What is Sahlins' domestic mode of production?
Marshall Sahlins' term (1972) for an economy in which the household produces only for its own needs, using its own labour, as an autonomous economic and political unit. The family changes when kinship and political systems demand surplus production beyond the household.
