Socioeconomic factors affecting fertility in the developing countries and of the developing population groups in
Abstract:
"In the present paper...socioeconomic factors affecting the fertility of the developing population groups in South Africa, are discussed and compared with findings [for developing countries] from the WFS [World Fertility Survey]." Data for South Africa are from an independent survey conducted during 1981-1982. "The relationship between socioeconomic factors and three dependent variables (marital fertility, desired family size, and current contraceptive use) is analysed.... The analyses are restricted to the examination of the extent to which the wife's differentials in fertility and associated variables related to education, employment status, and rural/urban residence persist, when other socioeconomic characteristics of the couple are controlled statistically."
