We still know remarkably little about the voting behavior of immigrant populations, and in particular, the children of immigrants – who grow up in the same society as their contemporaries, but may be subject to different patterns of socialization. This article uses verified voting behavior in Swedish municipal elections to offer at least two new perspectives on these questions. First, we are able to separate out the impacts of family socialization, general societal socialization, and citizenship acquisition on electoral participation. Second, we are also able to add to our knowledge of the differences in political participation levels between different groups of foreign-background voters.
