Desired family size and its determinants among urban Nigerian women: a two-stage analysis.

This paper proposes and carries out a two-stage analysis of the determinants of desired family size, using data gathered from a sample of women in the city of Ilorin, Nigeria. The analysis first focuses on differences between women who report numerical family size desires and those who report nonnumerical desires. Findings suggest that there are important differences between these two groups, but there is little variation in the actual number reported by those expressing numerical desires. Implications of these findings for survey design are discussed. In particular, the practice of forcing numerical responses by instructing interviewers to probe when women report nonnumerical desires is questioned.
