Researchers used the Netherlands’ refugee dispersal policy, which allocates refugees across regions in a largely unpredictable way, to study whether housing location affects social contacts. They combined a longitudinal survey of Syrian refugees with register data describing the ethnic makeup and urbanity of their housing regions.

Regions with a larger share of Syrian-descent residents led to more contacts with other Syrians. Regions with a larger share of Dutch residents led to more contacts with Dutch people, with tentative evidence of a positive effect on contacts within refugees’ own origin group as well. The effects did not diminish over five years, and urbanity had no robust effect.
