Countering linear acculturation theories, the adoption of Western European gender customs over time differs across migrant groups. This diversity implies that acculturation into support for gender equality is context dependent. However, little quantitative scholarship has identified what sort of contexts strengthen or impede acculturation. This article investigates one source of context-dependent acculturation: exclusionary contexts. I build and test a context-dependent exclusions framework that proposes that contexts that exclude non-Western migrants hamper their acculturation into support for gender equality in the labor market in Western Europe. Empirically, I synchronize European Social Survey, European Values Study, and Eurislam data on over 11,000 non-Western migrants in Western Europe. Cross-classified models show that non-Western migrants’ support for labor-market gender equality is, indeed, lower in exclusionary contexts, for instance, in destinations with stronger anti-migrant sentiments. Pivotally, the impact of destinations’ gender customs on migrants’ gender values differs across destination, origin, and community contexts. For instance, in destinations with stronger populist right-wing parties, migrants internalize destinations’ gender equality less. Altogether, non-Western migrants’ acculturation into support for labor-market gender equality is highly dependent on contextual exclusions, which means that populist claims about non-Western migrants’ universal lack of acculturation into support for gender equality should be viewed cautiously.
