Caste, class and family in India

Sociology (BA) · Indian society · free study notes for exams, placements and interviews

In short

Caste, class and family are the three institutions through which Indian society organises status, resources and reproduction. Caste is a hereditary, endogamous, ritually ranked group; class is an economic position defined by property, occupation and income; family is the kin group that produces, socialises and inherits. Their interaction explains Indian realities that neither alone can — why a landowning farmer caste votes as a bloc, why a Dalit graduate still faces exclusion, why dowry rises with family income. Examined in BA/MA Sociology papers on Indian society, in UPSC Sociology and GS Paper I, in UGC NET Sociology Unit on Indian social structure, and used professionally in CSR and development work, HR diversity-and-inclusion roles, market research on household consumption, journalism, and public-policy and welfare administration.

Formulas and examples

Sociology has few algebraic formulas; the measures below are the ones examined and used in survey and policy work.

Sex ratio = (number of females / number of males) × 1,000 — expressed as females per 1,000 males
Child sex ratio = females aged 0-6 per 1,000 males aged 0-6
Mean household size = total population in households / number of households (persons per household)
Index of jointness (operational) = (number of joint/extended households / total households) × 100
Endogamy rate = (marriages within the same jati / total marriages) × 100; inter-caste marriage rate = 100 − endogamy rate
Gini coefficient G = area between Lorenz curve and line of equality / total area under the line; 0 = perfect equality, 1 = maximum inequality (dimensionless)
Index of dissimilarity D = ½ Σ |pᵢ − qᵢ|, where pᵢ and qᵢ are the percentage shares of two groups in category i (result in percentage points; if proportions are used instead, multiply by 100)

Example 1 — Household size and family type in a village survey. A survey covers 400 households and 2,180 persons; 96 households have two or more married couples or three generations co-resident.

Example 2 — Endogamy and inter-caste marriage. Of 1,250 marriages recorded in a block, 1,163 are within the same jati.

Example 3 — Caste-class correspondence from a land-holding table.
