Son preference and the demand for additional children in Pakistan.

This paper tries to take into account the sequential element in fertility decisions and continues an investigation originally begun by Namboodiri. We examine the extent to which the "desire to have additional children" can be explained by a variety of economic, sociological, and demographic variables. The probit maximum likelihood estimation procedure is utilized, and the analysis is based on cross-sectional data on 2,910 currently married women obtained from a national survey conducted in Pakistan in 1968-1969. The principal finding is the presence of a strong son preference both for the husband and for the wife.
