Migration, natality and fertility: some Caribbean evidence

Area of Science:

• Demography
• Sociology
• Caribbean Studies

Background:

• Postwar Caribbean experienced significant external migration, primarily of young, reproductive-age individuals.
• Migration patterns have profound, yet often understudied, effects on the demographic structures of both sending and receiving societies.

Purpose of the Study:

• To analyze the macrolevel influence of external migration on the demographic behavior of Caribbean islands.
• To examine the relationship between migration, natality, and population growth in the Caribbean region.

Main Methods:

• Macrolevel analysis of demographic data from Caribbean islands.
• Examination of population trends, birth rates, and age-sex structures in relation to migration flows.

Main Results:

• Massive outward migration of young, reproductive-age cohorts (especially females) has inversely affected natality and population growth in Caribbean sending societies.
• Conversely, receiving societies experienced reversed effects, with increased natality and population growth.
• Indirectly, migration-induced age-sex imbalances may influence fertility patterns by affecting mating behavior and family formation.

Conclusions:

• External migration is a key determinant of demographic change in the Caribbean.
• The selective nature of migration significantly shapes population dynamics, fertility, and growth in both sending and receiving regions.
• Further research is needed to fully understand the indirect impacts of migration on family formation and fertility patterns.
