What is kinship? Briefly explain G. P. Murdock’s contribution to the study of the kinship system. (2025)

Kinship is the socially recognised network of relationships built on two principles: consanguinity, relatedness through socially acknowledged common descent, and affinity, relatedness created by marriage. It is not biology restated but a structured system of statuses, roles, terminology and jural obligation, which A. R. Radcliffe-Brown insisted be read as rights and duties rather than sentiment. George Peter Murdock gave that structure its first comparative map.

Kinship as a system, not a list of relatives

  • Three layers that answers routinely blur: terminology (what you call people), behaviour (avoidance, joking relationships, the mother’s brother’s obligations) and groups (family, lineage, clan).
  • Kin are graded outward as primary (parents, siblings, spouse, children), secondary and tertiary. Kinship matters sociologically because it allocates scarce things: property, office, ritual duty, marriageability.

Murdock’s contribution

  • Social Structure (1949), resting on a coded sample of 250 societies, from the Cross-Cultural Survey he began in 1937, institutionalised as the Human Relations Area Files (1946) and the Ethnographic Atlas (1967). Coded comparison and statistical correlation replaced armchair evolutionism with testable propositions.
  • The universality of the nuclear family, performing four functions everywhere: sexual, reproductive, economic and educational.
  • Six kinship terminological systems: Hawaiian, Eskimo, Iroquois, Sudanese, Omaha and Crow. The payoff is that terminology correlates with descent and residence rules, so what people call each other reveals how a society distributes rights.
  • A theory of change: residence rules shift first, dragging descent rules and finally terminology behind them.

Critique

  • E. Kathleen Gough (“The Nayars and the Definition of Marriage”, 1959) showed that among the Nayar the matrilineal taravad did the residence, economics and childrearing while sambandham partners acquired no rights: on Murdock’s own criteria the nuclear family was absent. Melford Spiro’s Israeli kibbutz and R. T. Smith’s matrifocal Caribbean household repeat it.
  • His functionalism assumes fit, reads the sexual division of labour off biology, and cannot see conflict or patriarchy inside the household, as Ann Oakley objected.
  • India tests the scheme hardest. Irawati Karve’s four zones (Kinship Organisation in India, 1953) cut across his terminological types; the decisive Indian variable, caste endogamy, has no cell in his coding.
  • The universal is contested now. In Deepika Singh v. Central Administrative Tribunal (2022) the Supreme Court held that “atypical” units, including unmarried partnerships and queer relationships, are familial; Supriyo v. Union of India (2023) withheld marriage equality yet left such households socially real.

Conclusion

Murdock made kinship comparable, and comparability is what turned its study into a science. But the universal nuclear family was a generalisation from a coding sheet, falsified by the Nayar then and by Indian household forms now. His method outlives his conclusion.
