Revision summary
Fecundity is the ability to conceive. Fertility is the count of live births. Intermediate variables connect the two. Indian age at marriage and breastfeeding are cultural brakes or accelerators. Infertility and high fertility are different public problems.
Model answer
Introduction
Fecundity is the biological capacity to conceive. Fertility is the actual production of live births. Demography and anthropology keep the two apart.
Body
The distinction
- A fecund couple may have low fertility because of late marriage, breastfeeding, contraception, or loss.
- Natural fertility populations, in Henry’s sense, lack deliberate parity limitation but still space births by lactation.
- Davis and Blake listed intermediate variables: intercourse, conception, and gestation.
Anthropology
- Age at marriage, widow remarriage, and son preference shape Indian fertility more than fecundity alone.
- Infertility stigma is social. Biomedical fecundity problems need clinics; high fertility needs policy and gender analysis.
- Bongaarts later modelled proximate determinants that operationalise the same split.

Conclusion
Fecundity is potential. Fertility is births achieved. Culture sits between them, which is why anthropology belongs in population study.

-
Can fertility exceed fecundity?
No. Births cannot exceed biological capacity; they can fall far below it.
-
Is fecundity the same as fecundability?
Fecundability is the monthly chance of conception; fecundity is the broader capacity.

Differences between Social Anthropology and Sociology.
The Nature of Society
Social anthropology grew from intensive fieldwork in small-scale societies. Sociology grew from industrial class, state, and survey. Malinowski versus Durkheim is the textbook origin split. Srinivas and Béteille show the Indian overlap. The wall is departmental, not a law of nature.

Cultural Relativism
The Nature of Culture
Relativism asks that custom be read in its own history. Boas used it against unilinear racial stages. Herskovits and Benedict spread it as method and public teaching. It is a brake on ethnocentrism, not a moral blank cheque. Rights debates mark its political edge.

Lineage and Clan
Kinship
Lineage members can show genealogical links to an ancestor. Clan members share a putative ancestor and often a totem. Lineages nest inside clans in many segmentary systems. Nuer feud and fusion made the distinction famous. Both groups are commonly exogamous.
