The immigration-crime relationship: Evidence across US metropolitan areas

Despite popular commentary claiming a link between immigration and crime, empirical research exploring this relationship is sparse. Especially missing from the literature on immigration and crime is a consideration of how immigration affects rates of crime at the macro-level. Although individual-level studies of immigrant criminality and victimization tend to demonstrate that immigrants typically engage in less crime than their native-born counterparts, the effect of immigration on aggregate criminal offending is less clear. In this research, we attempt to address this weakness in the literature by examining the effects of aspects of immigration on crime rates in metropolitan areas. We combine 2000 US Census data and 2000 Uniform Crime Report data to explore how the foreign-born population influences criminal offending across a sample of metropolitan areas. After controlling for a host of demographic and economic characteristics, we find that immigration does not increase crime rates, and some aspects of immigration lessen crime in metropolitan areas.
