What explains voter attitudes toward immigration in Latin America? This article argues that increased refugee arrivals moderate the impact of social identities on immigration attitudes. We propose that informational cues associated with increased immigration make cosmopolitan identities less important—and exclusionary national identities more important—determinants of immigration preferences. Analyzing 12 Latin American countries from the 2017–2022 wave of the World Values Survey, we demonstrate that cosmopolitanism is positively associated with pro-immigration attitudes, but only in countries experiencing low-to-moderate refugee inflows. Conversely, nationalism is negatively associated with pro-immigrant attitudes, and increasingly so as refugee inflows increase. The uneven distribution of refugee migration has therefore reshaped public opinion in Latin America by moderating the effects of competing social identities (i.e., cosmopolitanism and nationalism). These findings contribute to broader debates on the behavioral impacts of immigration by highlighting an indirect mechanism by which increased immigration may generate anti-immigrant hostility.

Education is widely believed to predict attitudes toward immigration, but what causal relationship underlies this descriptive pattern? This research employs three distinct natural experiments and considers genetic factors to triangulate this relationship: Study 1 analyses discordant monozygotic twins; Study 2 assesses the impact of a Swedish education reform; and Study 3 analyses dizygotic twins with the use of a polygenic index for education, a DNA-based measure for genetic predispositions toward education. The results indicate that education does modestly promote open views toward immigration (Study 1), yet the reform’s effect remains uncertain (Study 2). Study 3 offers direct evidence of the effects of genetic predispositions and suggests that genetics related to education may influence attitudes beyond achieved educational attainment. These findings confirm the positive impact of education while pointing to the combined influence of genetic and social pathways in shaping immigration attitudes.

There is a large discrepancy in European countries between the measured impact of immigration on the welfare state and how this impact is perceived by citizens. This study examines the determinants of individuals’ perception of the impact of immigration on the welfare state. A number of hypotheses at both the individual and contextual level are tested using a multilevel model with data from the European Social Survey. I find that the institutional features of welfare states are associated with different views on the impact of immigration on welfare states: generous contributory social welfare benefits are associated with more favourable attitudes about immigrants, while generous non-contributory benefits, by contrast, are associated with more pessimistic assessments about the fiscal impact of immigration. I argue that this can be because the latter potentially signals to natives that migrants could access generous benefits without any requisite work history. At the individual-level, the results indicate that subjective risk and general opposition to immigration are powerful individual-level predictors: people who feel more economically insecure or who are generally opposed to immigration are more likely to think that it constitutes a burden for the welfare state.

This article provides an overview of the literature on the relationship between terrorism and migration. It discusses whether and how (1) migration may be a cause of terrorism, (2) terrorism may influence natives' attitudes towards immigration and their electoral preferences and (3) terrorism may lead to more restrictive migration policies and how these in turn may serve as effective counter-terrorism tools. A review of the empirical literature on the migration–terrorism nexus indicates that (1) there is little evidence that more migration unconditionally leads to more terrorist activity, especially in Western countries, (2) terrorism has electoral and political (but sometimes short-lived) ramifications, for example, as terrorism promotes anti-immigrant resentment and (3) the effectiveness of stricter migration policies in deterring terrorism is rather limited, while terrorist attacks lead to more restrictive migration policies.

The sociocultural divide in Western Europe is increasingly focused on issues of national identity, namely immigration. It is commonly assumed that opponents of immigration also exhibit conservatism on other sociocultural issues. Yet recent research suggests that general social conservatism is declining in the region. Do immigration attitudes fit squarely into the sociocultural dimension? Using survey data from eleven West European countries, as well as a Dutch household panel from 2007–2019, this study finds that gender attitudes, a key sociocultural issue, are subject to change through both cohort and life cycle effects, while immigration attitudes are stable over the course of the panel and exhibit little variation across cohorts. Immigration attitudes also appear to be immune to period effects resulting from the 2015 refugee crisis. Further, those born during and after the ‘post-materialist revolution’ have weakened associations between these two attitudes, while older individuals' attitudes are strongly correlated. The combination of gender egalitarianism and anti-immigrant sentiment may become increasingly common as acceptance of the former spreads, while immigration remains a hotly contested issue.

Are the predictors of anti-immigration attitudes consistent across countries with diverse immigration histories and policies? We hypothesize that the key predictors of opposition to immigration are indeed relatively consistent across industrial nations. We test this hypothesis with two surveys using probability samples of German citizens. We then compare our findings with those obtained in recent studies of immigration opinions in Europe generally, and in two of the world's leading immigration-receiving nations: Canada and the United States. Striking similarities emerge in the findings across structural, demographic, contact, economic, political, personality, and threat predictors. Opposition to immigration is routinely found strongest among the older and less-educated segments of the population who live in areas with anti-immigration norms and little contact with immigrants. Anti-immigration attitudes also correlate with political conservatism and alienation, economic deprivation, and especially with authoritarianism, social dominance orientation, and perceived collective threat.
