Assortative Mating for Educational Level in Parents of Public School Children (N > 7000 Individuals) in the Lagos State, Nigeria

Assortative mating for educational level is a widespread phenomenon in Western industrialized societies. However, whether or not the results from Western samples can be generalizable to populations in developing countries in Africa remains to be seen. The present study investigated assortative mating for educational level in parents of public school children (N > 7000) in the Lagos State in Nigeria. Approximately 61.5 % of the parents had spouses at the same level of education. More mothers than fathers married upward in educational level. The assortative mating coefficients for educational level were .52-.61 across respondents' classes, .51-.62 across six school districts, and .57 (.55-.59) in the total sample. Overall, these results were very similar to the findings from Western or Asian samples, providing evidence to support the robustness of human mating pattern in educational attainment across different cultures and ethnic groups. The present findings should be incorporated in future quantitative and molecular genetic studies on Africans.
