This study aims to investigate immigrant fathers’ use of parental leave for a first child in Sweden from 1995 to2010. The issue of immigrant fathers’ uptake of parental leave is particularly well suited to assess the integrativeaspects of family policies and for studying immigrants’ integration because it reflects labour market participationand acceptance of gender-equal parental norms. Using data from Swedish population registers, we find thatimmigrant fathers do take parental leave but not to the same extent as Swedish-born fathers do, and they donot respond equally to policy changes. Our most important finding is that immigrant fathers increase their leaveuse with time spent in Sweden, indicating an adaptation to the leave-use pattern of Swedish-born fathers. Wealso find that individual income, as well as the mothers’ characteristics, are strong determinants of parental leaveuse.
