Fertility levels and differentials in Beirut during wartime: an indirect estimation based on maternity registers.

In this paper, total fertility estimates for Greater Beirut in the mid-eighties and early nineties are presented, and changes in socio-religious differentials of fertility across time are explored. The baseline information was recorded from registration details for all maternities in Beirut and its inner suburbs in 1984 and 1991: age of mother, number of children ever-born, hospital class, and religion of newborn. An indirect method was used to estimate total fertility from the joint distribution of mothers by age and parity, and, using hospital class as a proxy for social class, differentials in fertility were investigated by Poisson regression. The estimates of total fertility for Beirut shifted from 2.60 in 1984 to 2.52 in 1991, and were higher for Muslims than for Christians in the two periods. The regression analysis showed that: (1) the difference between the two religious groups persisted after control for social class, and in fact applied to the lower social class; (2) fertility dropped between the two dates in the lower social class, and more so for Muslims than for Christians. In comparison with other countries of the region, the decline in Beirut was found to be relatively modest. If the trends assessed in this study were to continue, the religious-based fertility differentials would taper off progressively in the capital city of Lebanon.
