This study identifies the determinants of the probability of having subsequent births among rural and urban women in Bangladesh. Data were obtained from the 1989 Bangladesh Fertility Survey among a 2-stage sample of 11,905 ever-married women aged 10-49 years. 8466 lived in rural areas; 3439 lived in urban areas. Analysis relied on tabular analysis, nonparametric survival analysis, and Cox proportional hazard regression models. The dependent variable is birth intervals in single months at different parities up to 144 months. Explanatory variables are demographic, socioeconomic, cultural, and decision-making ones and period effects. Findings reveal that different factors affected first births and higher order births. The subsequent births to women in rural areas were affected by more factors. Some variables consistently affected all subsequent births, while others had other impacts. For example, education increased the risk of having a first birth, but decreased the risk of subsequent births. Husband's education was a significant factor in first births and insignificant in higher order births. The period effect was significant for all births. Findings confirm that fertility is recent and stronger in urban areas and will continue to decline. Greater urbanization is likely to lower fertility. Risk of subsequent births was related to work experience. Religion was significant in higher order births in rural areas, but it was insignificant in urban areas. Residence in Dhaka resulted in a lower risk of a first birth compared with Chittagong region. Rural regions had lower risk of higher order births than Chittagong region. Son preference was not a significant factor.
