ABSTRACT This study examines polarization in political opinions toward immigration and the European Union between occupational classes, i.e. structural polarization. We maintain that two conditions must hold to indicate structural opinion polarization: high between-class divergence and high within-class consensus. Our main contribution is to study these two conditions systematically for a wide variety of immigration and EU-related topics. Using data from four high-quality German surveys spanning three decades, we document three main findings. First, we find substantial between-class divergence: respondents in typical working class occupations express substantially more unfavorable opinions about immigration and the EU than the upper classes across the majority of survey indicators. Second, however, we also observe considerable opinion heterogeneity within the working class. This lack of within-class consensus limits the potential of mobilizing the working class as a group on the basis of anti-immigration and anti-EU sentiments. Third, while we do not document durable increases in structural opinion polarization over time across most of our opinion indicators, we do draw attention to those individual indicators that show relatively high polarization. Overall, our results suggest limited opinion polarization between occupational classes on immigration and EU issues in Germany.

ABSTRACT The utilitarian approach to pro-EU attitudes – noting that citizens establish their preferences based on their perceived self-interest – remains the dominant one in the social science literature on these attitudes. Yet previous work following this approach has overlooked the role of subjective financial insecurity. Based on prospect theory and marginal utility theory, we argue that individuals who feel financially insecure determine their preference for further European unification in terms of the gains and losses for themselves and that, since they are disproportionately sensitive to economic losses, they display more risk aversion and oppose further macro-political changes in the form of further European unification. Using hybrid models and 15 waves of a representative panel survey conducted in the Netherlands and covering 2008–2023, the evidence strongly supports our expectation. Controlling for individual education, occupational status, individual income, gender and age, subjective financial insecurity is cross-sectionally and longitudinally related to support for European integration. People generally feeling financially insecure (those who over time increased their feeling of financial insecurity) display significantly less support for further European unification than people who generally feel financially secure (people who over time did not feel more financially insecure).

ABSTRACT Attitudes towards intergroup dating and their determinants are important to comprehend group boundaries of multicultural societies. Our contribution investigates gender and ethnic differences in intergroup dating approval among 18 year olds from 11 ethnic groups in Belgium. We observe ethnic differences in the level of approval of intergroup dating. However, these ethnic disparities are largely explained by the degree of sexual liberalization, parental control and religiosity. Moreover, the associations of parental control, sexual liberalization and religiosity with attitudes towards intergroup dating differ for girls and boys. We conclude by highlighting the relevance of the interaction of gender and ethnic origin in shaping attitudes towards intergroup dating.
