Number of siblings and school achievement in sub Sahara Africa

This paper uses biographical data from Dakar and Yaounde, two big African cities, to study the link between the number of siblings and school attainment. The data describe all fertility events meet by parents and the sibling's size structure of every child over time. The average sibling size effect is estimated first. Then, the sibling's size at given age effect is estimated. The results show that, in Dakar, both the overall and age specific siblings size effect on education are negative and statistically significant. In Yaounde, the overall effect is not significant, but we observed negative effects at some schooling ages (between 14 and 16).
