Which Factors Explain the Rising Ethnic Heterogeneity in Italy? An Empirical Analysis at Province Level

The paper investigates the determinants of ethnic heterogeneity of the Italian provinces.

Consequently to easier communication, movers increasingly rely on an enlarged community for identity transmission, rather than on localized peer effects of the ethnic enclaves. The empirical estimation provides support to this hypothesis. Improvements in internet communications are found to increase the ethnic diversity of the Italian provinces
