Segmented assimilation, local context and determinants of drug violence in Miami and San Diego: does ethnicity and immigration matter?

Does the ethnic and immigrant composition of a community and existence of immigrant enclaves or barrios influence community level drug violence?

The findings lend some support to the positive and negative aspects of Portes and Rumbaut's (2001) segmented assimilation hypothesis in Miami and San Diego neighborhoods. The strength of this conclusion varies and is contingent upon ethnic composition, new versus old immigration, and the all-encompassing effects of economic deprivation
