Cohort, Policy, and Process: The Implications for Migrant Fertility in West Germany.

Although a growing literature explores the relationship between migration and fertility, far less scholarship has examined how migrant childbearing varies over time, including across migrant cohorts. I extend previous research by exploring migrant-cohort differences in fertility and the role of changing composition by education and type of family migration. Using 1984-2016 German Socio-Economic Panel data, I investigate the transition into first, second, and third birth among foreign-born women in West Germany. Results from an event-history analysis reveal that education and type of family migration-including marriage migration and family reunions-contribute to differences in first birth across migrant cohorts. Specifically, more rapid entry into first birth among recent migrants from Turkey stems from a greater representation of marriage migrants across arrival cohorts, while increasing education is associated with reduced first birth propensities among recent migrants from Southern Europe. I also find variation in the risk of higher parity transitions across migrant cohorts, particularly lower third birth risks among recent arrivals from Turkey, likely a result of changing exposures within origin and destination contexts. These findings suggest that as political and socioeconomic circumstances vary within origin and destination contexts, selection, adaptation, and socialization processes jointly shape childbearing behavior.
