Quantifying immigrant diversity in Europe

The notion of increasing immigrant diversity is prevalent in immigration literature. However, little empirical research has examined if immigrant populations have become more diverse during the past two decades. Using data from Pew Research Center's Global Religion and Migration Database and the World Bank's Global Bilateral Migration Database, origin and religious change in immigrant populations since 1990 is presented for six European countries. Findings demonstrate that immigrant origin and religious diversity has been relatively stable during the past ten years, with moderate increases during the 1990s. Further research can examine whether these patterns are true for other countries or what happens when alternative variables are considered.
