Note

1. Average age at marriage increases with education level—and this correlation is stronger in SSA than in other regions. This may be because education for women is more rare in SSA and differences in age at marriage therefore reflect the exceptional differences in the lives of the most educated. Since female education is a more recent phenomenon in SSA, the difference in age at marriage may also capture both education and cohort effects. Interestingly, these larger differences in age at marriage were not yet reflected in differences in fertility in the early 1980s (Cochrane and Farid 1989).
