Abstract: This paper estimates the effect of social connectedness on crime across U.S. cities from 1960- 2009. Migration networks among African Americans from the South generated variation across destinations in the concentration of migrants from the same birth town. Using this novel source of variation, we find that social connectedness considerably reduces murders, robberies, assaults, burglaries, larcenies, and motor vehicle thefts, with a one standard deviation increase in social connectedness reducing murders by 13 percent and motor vehicle thefts by 9 percent. Our results appear to be driven by stronger relationships among older generations reducing crime committed by youth.
