Abstract

Opportunity for selection has been studied against their contrasting socio-economic and cultural backgrounds in two endogamous populations, namely, Brahmins and Jalaris of Visakhapatnam, India. Total selection was slightly higher among the better off Brahmins than in Jalaris. But a marked qualitative and quantitative variation was found in the contributing components; the fertility differential was circa 60% in Brahmins while the mortality differential was circa 60% in Jalaris according to the Crow Index. The decreased mortality differential in Brahmins suggests that this component was directly affected by the better socio-economic level and reflects on the population’s transitional phase. Further, the If value fell to a half in women who completed their fertility by family planning when compared to women who completed their fertility by menopause, thus reducing the variance in fertility component in the family planning group.
