How do migrations affect under-five mortality in rural areas? Evidence from Niakhar, Senegal

Abstract : This study analyses the relationship between a household member’s migration and child mortality within the family left behind in rural areas. Exploring the richness of the Niakhar Health and Demographic Surveillance System panel, we use high-frequency migration data to investigate the effects of migration on child mortality at the household level over 16 years. Migrations, particularly short-term migrations, are positively associated with the survival probability of under-five children in the household. Also, we find that working age women's short-term migrations impact child mortality more than working age men's short-term migrations. This observation supports hypotheses in the economic literature on the predominant role of women in rural households in obtaining welfare improvements. Moreover, we detect crossover effects between households of the same compound –in line with the idea that African rural families share part of their migration-generated gains with an extended community of neighbors. Lastly, we investigate the effect of a mother's short-term migration on the survival of her under-5 children. The aggregate effect of a mother’s migration on child survival is still positive, but much weaker. Specifically, mother migration during pregnancy seems to enhance the wellbeing of the child, considered immediately after birth. However, when the child is older (more than one year), the absence of the mother tends to decrease the probability of survival.
