Fertility and mortality differentials among the Paundra Kshatriya community living in a peri-urban setting, West Bengal, India
Abstract
Relationship between fertility and mortality is well known, which exists among different populations of the world. This is known as a genetic phenomenon that has been operating in all human populations. This study examines fertility and mortality differentials among the Paundra Kshatriya community living in a peri-urban setting of West Bengal, India. Altogether, 249 Paundra Kshatriya women were interviewed. A subsample was drawn from this sample, numbering 98, who have completed their reproductive span. Differential fertility is 0.3134 and differential mortality is 0.1393, whereas, index of total selection intensity is 0.4964 according to Crow’s (1958) formula and 0.5980 according to Johnston and Kensinger’s (1971) formula in the study population. The higher value according to Johnston and Kensinger’s (1971) formula is probably because of inclusion of embryonic deaths in the latter. Findings of the present study reveals that differential fertility (If: 0.3134) contribute more than the differential mortality (Im: 0.1393) towards the total opportunity for selection (I=0.4964) in the study population. Paundra Kshatriya is placed with other populations of West Bengal like Jale, Tili, Muslim, Kayastha, Paschtya Vaidya Brahmin, Duley Bagdi, Namasudra and Lepcha in this respect.
