Data from the 1981-82 Nigeria Fertility Survey (NFS) are used to identify the key proximate determinants of fertility in Nigeria. The patterns of their individual and collective effects are analyzed in a search for possible sources of fertility change. Exposure to the risk of childbearing through first marriage is found to be the most important proximate determinant of Nigerian fertility. Subsequent to marriage, fertility is determined mainly by breastfeeding and postpartum sexual abstinence. Where fertility shows significant socioeconomic variations, there are equally identifiable patterns of the impact of the proximate determinants which explain these differentials to a large extent. On a national scale, the observed patterns of the impact of the measured proximate determinants do not appear to suggest that Nigerian fertility is soon to experience a large decline.
1981 - 1982年尼日利亚生育率调查（NFS）的数据被用于确定尼日利亚生育率的关键直接决定因素。分析了这些因素各自及共同作用的模式，以寻找生育率变化的可能根源。通过初婚面临生育风险被发现是尼日利亚生育率最重要的直接决定因素。婚后，生育率主要由母乳喂养和产后性禁欲决定。在生育率存在显著社会经济差异的地方，同样可以识别出直接决定因素的影响模式，这些模式在很大程度上解释了这些差异。在全国范围内，所观察到的已测量直接决定因素的影响模式似乎并不表明尼日利亚的生育率很快会大幅下降。
