Intermediate variables and educational differentials in fertility in Korea and the Philippines.
This analysis compares the effects of contraceptive use and infant and fetal mortality on the pace of fertility in Korea and the Philippines and explores the mediating effects of these intermediate variables on educational differentials in childspacing. For both intervals initiated in a recent period before a sample survey, second, third and higher-order intervals are examined. Transitions within successive segments of interval exposure (qx values) are examined rather than cumulative transitions (1 - lx values). This methodological choice is substantively important because breastfeeding should primarily affect early segments of exposure and because it allows empirical examination of the timing of the effects of other variables such as contraceptive use. Further, this choice allows multivariate analysis within the structure of the life-table perspective. The results show substantial differences in patterns between Korea and the Philippines, indicate clearly the effect of each intermediate variable, and illustrate how educational differentials in fertility are affected by contraception and infant and fetal mortality.
