Understanding the proximate determinants of fertility of a Nigerian ethnic group.

"This paper uses data from a 1992/93 sample survey of 1,000 women aged 15-49 in selected areas of Imo State, Nigeria. The purpose of the survey was to get information/data on birth-spacing dynamics of the area. In this paper, we applied the basic Bongaarts model and its extended version to identify the proximate determinants of Igbo fertility. A total fertility rate [of] 6.7 births per woman is estimated from the model compared with a TFR of 7.26 actually observed from the survey. When compared with earlier studies, it is shown that the principal proximate determinant of fertility in the area is no more lactational infecundability, but delayed marriage. Explanations for this change, future research needs and policy implications are discussed." (SUMMARY IN ITA AND FRE)
