Migration, Marriage, and Cohabitation among Hispanic Immigrant Women in the United States.

Prior research shows links between the timing of migration and family formation, particularly childbearing, among Hispanic immigrants in the United States, with implications for women's socioeconomic well-being. However, temporal connections between migration and union formation, particularly non-marital cohabiting unions, remain underexplored. As cohabiting unions have long coexisted with marriage in parts of Latin America, this omission may be particularly misrepresentative of the family formation strategies of Hispanic immigrants. Drawing on data from the National Survey of Family Growth (2011-2017), I examined the association between the timing of migration and entry into first marital or non-marital (cohabiting) union, treating marriage and cohabitation as competing events for first union type. Among women whose first union was non-marital, I also examined the relationship between migration and the likelihood of transitioning out of the non-marital union, either through marriage or union dissolution. Results showed that marriage formation was high the year of migration, and increased again only after 6 years post-migration, whereas cohabitation was high the year of migration and continued to increase with each period following migration. Furthermore, non-marital unions formed prior to migration were likely to transition to marriage or dissolve, while those formed after migration were likely to remain non-marital. These findings point to distinctions in the types of partnerships formed before and after migration and to the salience of non-marital unions for women who migrate unpartnered, demonstrating the need for further research on the socioeconomic integration and well-being of unmarried or cohabiting immigrant women, and the dynamic connections between migration, gender, and family.
