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.
