The present study provides an investigation of patterns in child¬bearing among foreign-born women in Sweden during the 1960s to 1990s. Event-history techniques are applied to longitudinal population-register data on childbearing and migration of 446.000 foreign-born women who had ever lived in Sweden before the end of 1999. Period trends in parity-specific fertility appear to be quite similar for Swedish- and foreign-born women but important differences exist in levels of childbearing propensities between women stemming from different countries. Most immigrant groups tend to display higher levels of childbearing shortly after immigration. We conclude that migration and family building in many cases are interrelated processes and that it is always important to account for time since migration when fertility of immigrants is studied.
