The chapter addresses questions regarding popular support for the Nordic welfare state(s), with a special focus on ethnic diversity and immigration. It examines theoretical assumptions and empirical evidence from the perspective of welfare attitude research and presents data from the 2008 round of the European Social Survey. Here, the chapter focuses on the attitudes of immigrants themselves in comparison with other respondents, in order to discern whether and how immigrants differ from native-born populations with regard to their attitudes towards certain welfare-state issues. The chapter shows that increasing ethnic heterogeneity has not undermined the popular legitimacy of the Nordic welfare states. It also concludes that immigrant attitudes in general do not seem to differ greatly from those of the general popular opinion, either in the Nordic welfare-state model or in other welfare-state models.
