Succeeding without belonging? A double comparison of migrants’ socio-economic attainment and national belonging across origin and residence countries

When is migrants’ socio-economic attainment associated with enhanced national belonging to their residence country? Drawing on a large-scale survey, we compare migrants from the same 10 origin countries across Denmark, Germany, and the Netherlands. We exploit this double comparison across origin groups and residence countries to contextualize mixed findings of positive, negative, and null associations between migrants’ socio-economic attainment and national belonging in earlier research. We introduce the notion of ethnic boundaries to situate when migrants’ socio-economic attainment and belonging are positively or negatively associated. We examine how migrants’ socio-economic attainment interacts with contextual variation in ethnic boundaries and with individual-level variation in perceptions of ethnic boundaries based on perceived group discrimination. Multi-group structural equation models show that migrants’ socio-economic attainment is often decoupled from national belonging. However, they also reveal crucial contextual variation as same-origin migrants can succeed socio-economically with or without feeling belonging in different residence countries. At the individual level, perceived group discrimination conditions this association, so that socio-economic attainment translates into more national belonging only when perceptions of discrimination are low. Our comparative findings of contingent national belonging thereby challenge existing assumptions that associations between socio-economic attainment and national belonging are linear and that ethnic boundaries in European migration contexts are rigid.
