Background: Spain, a country with one of the lowest fertility levels in the world, has recently received intense immigration flows that may contribute to fertility recovery.

Objective: The objective of this study is to examine whether the childbearing behaviour of immigrant women and their descendants shows a pattern of convergence with that of Spanish women born in or after 1950.

Methods: After merging data from the Fertility and Values Survey (2006) and the National Immigrants Survey (2007), we analyse the transition to first, second, and third birth using event history models, to identify variations in timing and incidence of birth transitions between native Spanish women and immigrant groups.

Results: Previous literature has found that migration disrupts immigrants’ fertility only temporarily; however, in the case of Spain, most migrant women who moved before starting family formation do not seem to fully compensate for migration-related disruption of fertility at a later stage. Our findings challenge the widespread belief that immigrants’ childbearing alone will allow Spain to leave behind the current lowest-low and latest-late fertility scenario.

Contribution: This article analyzes for the first time the fertility of different immigrant generations in Spain compared to native women, applying event history techniques. Our findings challenge conventional wisdom that immigration will improve very low fertility levels in Spain.
