Objective:

To examine the association between household wealth and the timing of first birth among highly educated women in sub-Saharan Africa, highlighting its significance in understanding fertility transitions.

Key Findings:
  • By age 25, over half of women in the poorest quintile had a first birth, compared to about one third in the richest quintile, indicating significant disparities in reproductive timing.
  • Lower wealth quintiles had higher hazards of first birth: 19% higher for richer, 28% for middle, 42% for poorer, and 33% for the poorest women relative to the richest, suggesting a strong socioeconomic gradient.
  • The socioeconomic gradient in first-birth timing was strongest in Southern Africa, moderate in East Africa, and more compressed in West and Central Africa, highlighting regional variations that warrant further investigation.
Interpretation:

Household wealth significantly influences fertility timing among highly educated women, indicating that wealth inequality and economic insecurity play a crucial role alongside education, with implications for policy and future research.

Limitations:
  • The study may not fully disentangle the effects of education and wealth due to their correlation, which could affect the interpretation of results.
  • Cross-sectional data limits the ability to establish causality, suggesting the need for longitudinal studies to better understand these dynamics.
Conclusion:

The findings highlight the importance of considering household wealth in understanding fertility patterns among educated women in sub-Saharan Africa, suggesting that economic resources independently affect reproductive timing and should be addressed in policy discussions.
