Nativity concentration and internal migration among the foreign-born.

Are immigrants who live in states where large numbers of their compatriots reside more or less likely to migrate than those who live in other states? Using 1980 U.S. Census data to address that question, the analysis shows that nativity concentration deters interstate migration but not migration within the same state. Residing in a state where fellow nationals live is a more important determinant of internal migration than human capital, immigration status, or a state's unemployment rate. New York State residence in 1975 also promotes interstate migration. This research suggests that social dimensions should be taken into account in modeling internal migration of the foreign-born.
