Migration, natality and fertility: some Caribbean evidence.
"This research note explores the macrolevel impact of external migration on the demographic behavior of Caribbean islands. The analysis provisionally argues that the massive mobility of Caribbean peoples in the postwar era--primarily of young, reproductive (especially female), working-age cohorts--has inversely affected natality and population growth in sending societies, and reversed these effects in receiving societies. Results further suggest secondarily and quite indirectly that migration may also influence fertility patterns in similar directions through the impacts of age-sex imbalances on mating behavior and family formation."
