Replication Data for: Measuring Interethnic Marriage in Africa

Interethnic marriage is commonly employed in the African politics literature as an indicator of social cohesion. However, using intermarriage rates for this purpose may be misleading because intermarriages are a reflection of both preferences and opportunities. If we are to interpret intermarriage rates as indicators of people's willingness to cross group boundaries (and hence as a measure of social cohesion), we must find a way of controlling for exposure to out-group members in local marriage markets. In this Note, I exploit census data from Zambia to demonstrate how this can be done. The findings, which reveal significant differences across estimates that do and do not control for local exposure to out-group members, underscore a significant weakness in common approaches. The findings also point to important substantive implications for understanding changes in social cohesion in Zambia--and likely other African societies--over time.
