Birth interval pattern can be used to draw attention on the significant
characteristics of reproduction and dynamics of fertility transition. The focus of
current paper is to study the effect of socioeconomic, demographic and proximate
determinants on the length of birth intervals for Pakistani women. Cox Regression
Model is used for modeling the birth intervals. It is evident from higher order
birth interval models that age of women, preceding birth interval, education of
women and survival status of preceding child are major determinants of all birth
intervals. In the Proximate Determinant Models, period of breastfeeding and age
of women have played significant role in the determination of all birth intervals.
Enhancement in women’s education, discouraging gender biasness, improvement
in health facilities and promotion of long breastfeeding period can be helpful in
expanding the birth spacing.
