This paper examines the socioeconomic characteristics of rural-urban migrants, child mortality and maternity child health care in Ghana. Data from the 1988 Ghana Demographic and Health Survey shows that infant mortality is lower among rural-urban migrants compared to rural non-migrants. Proportional hazards model estimates reveal that the survival chances of children of rural-urban migration persist after controlling for socioeconomic characteristics. However, these advantages disappear after demographic variables are included in the model in spite of the proximity and accessibility to medical facilities enjoyed by the migrants. This finding suggests that socioeconomic and demographic characteristics of migrants could be an important determinant of the survival of children of rural-urban migrants.
