Companion figure: The gaps are smaller for surviving children (in black) than for children ever born (in gray), at the same grade levels—consistent with child survival and school quality shaping cross-regional fertility differences.
Panel plot by region (East Asia & Pacific, Latin America & Caribbean, South Asia) and age group (20–29, 30–39, 40–49). Y-axis: ‘Difference Between Sub-Saharan Africa and Region’ in children ever born and in the number of surviving; X-axis: Education (0–16 years). Differences are uniformly smaller for surviving children than for children ever born, especially around the end of primary school.

Figure: Differences in children ever born between SSA and other regions by years of schooling (ages 20–29, 30–39, 40–49). Gaps peak near the end of primary, then decline. Rural results shown here; urban similar.

After a long wait, the working paper for the Many-Economists Project: The Sources of Researcher Variation in Economics. We had 146 teams perform the same research three times, each time with less freedom. What source of freedom leads to different choices and results? papers.ssrn.com/sol3/papers....
