Religiosity of Migrants and Natives in Western Europe 2002–2018: Convergence and Divergence

Patterns of religiosity among both settled and migrant populations have been the subject of intense, and often conflicting, scholarly debate. In Europe, most analysis of migrant religiosity has focused on Islam, though migrants to Western European countries come from a wide range of religions and denominations. Despite a general assumption of assimilation over generations to greater secularization, evidence on trends in religiosity across migrants of different religions and for both first and second generations remains partial. We use the European Social Survey (rounds 1–9) to examine three dimensions of religiosity encompassing both performative and subjective domains, across 15 Western European destination countries over a 16-year period. While variation in religiosity between different affiliations is not large, migrants tend to have higher religiosity than non-migrants across the religious affiliations we consider. Over time we see that while natives show an overall decline in religiosity over the period, first- and second-generation Protestants and Muslims show increases in religiosity, providing some evidence for religious revival. We discuss the implications of our findings for theories of secularization and religious revival, and the future religious landscape of Europe.
