Polygyny and child survival in West Africa.

This study examines the relationship between polygyny and child survival in light of conflicting findings reported in a number of studies. Using data from the Demographic and Health Surveys from six West African countries, the risks of neonatal, postneonatal, and overall infant mortality are estimated. Controlling for a set of social and bio-demographic factors, it is found that substantial risks of mortality are associated with polygyny. A separate analysis explores the possibility that polygyny's impact could differ from country to country. No significant interaction effects are detected, leading to the conclusion that regardless of the country in which it is practiced, polygyny still poses a challenge to the survival chances of West African children.
