Title: “Sanctuary Policies and City-Level Incidents of Violence, 1990–2010”
Despite media coverage of isolated incidents of violent crime perpetuated by undocumented immigrants in cities with sanctuary policies, there is scant systematic research on the relationships between the adoption of sanctuary policies, unauthroized immigration, and crime. We compile city-level data from official sources and use fixed-effects negative binomial regression to examine whether the adoption of city-level sanctuary policies and the concentration of unauthorized Mexican immigrants are associated with homicide and robbery incidents in 107 U.S. cities, across three decades. Our findings clearly demonstrate that the implementation of sanctuary policies does not lead to higher violent crime rates. In fact, we find evidentce that the adoption of sanctuary policies is associated with a reduction in robberies. Moreover, an increase in the relative size of a city's unauthorized Mexican immigrant population corresponds with a reduction in homicide; however, only in sanctuary cities.
