Return Migration and Fertility: French Overseas Emigrants, Returnees, and Nonmigrants at Origin and Destination.

ABSTRACT

Although growing research has emphasized the critical importance of studying returns for understanding various aspects of migration processes, knowledge regarding return migrants' fertility behaviors remains limited. This study addresses this knowledge gap by comparing rates of first births and completed fertility among three groups nonmigrants (at origin), migrants, and return migrants. Using extensive data collected both in the home regions and at destination, we analyze female migration from Martinique, Guadeloupe, French Guiana, and Réunion Island to metropolitan France (European France). We find intermediate fertility behaviors for return migrants relative to nonmigrants and migrants on average, completed fertility levels are lower among return migrants than nonmigrants but slightly higher among return migrants than migrants. Some of these differences can be attributed to selection into migration and return, although significant gaps persist among women with similar socioeconomic characteristics. Our findings highlight three key observations. First, when migrants return before beginning childbearing, their transition to motherhood closely resembles that of nonmigrants with similar characteristics. Second, the lower fertility rates among prospective return migrants indicate an anticipation of disruption effects. Finally, reduced fertility while residing in metropolitan France translates into lower completed fertility rates for return migrants.
