This study investigates the association between women’s relative employment positions and the transition to parenthood, focusing on women of Maghrebi, Turkish, and Southern European origin in Belgium. Whereas gender specialization is associated with higher chances of entering parenthood in the older literature, the economic preconditions to parenthood have shifted and more recent studies indicate that couples where both partners work are more likely to start a family. However, whereas this shift has been extensively studied among majority populations, we lack insight into whether similar patterns can also be found among population subgroups with a migration background. This paper uses Belgian census data from 2011–2015 to explore how women’s relative employment positions are linked to the likelihood of entering parenthood and whether this association varies by women’s age, generation, and origin of the male partner. The results indicate that couples in which both partners are employed are more likely to enter parenthood regardless of migration background. However, the results for women of Maghrebi or Turkish background suggest that single-earner couples and couples where both partners are unemployed delay entry into parenthood to a similar extent.
