Chen, XuanyingThe consensus in the immigration-crime literature is that immigration either has a null or an inverse relationship with neighborhood crime (Ousey & Kubrin, 2018). These findings align with the “immigrant revitalization thesis,” which argues that immigration reduces neighborhood crime by producing immigrant social capital and developing community social control. However, the proposed revitalization process has been rarely tested empirically. This dissertation contributes to the current literature by examining the immigration-crime relationship at the neighborhood level and the intervening mechanism of immigration social capital using a large sample of neighborhoods across the U.S. Specifically, it investigates the mediating influence of stable families, multigenerational families, local businesses, and self-employment in the immigration-crime nexus. Using the newly collected National Neighborhood Crime Study 3 Pilot Panel data, I employ a series of fixed-effects and structural equation models (SEM) for violent crime and burglary. The findings highlight the importance of stable families, namely that immigrant neighborhoods bring in stable family structures that translate into less violence in the neighborhood. However, analyses do not find significant mediating influences for other forms of immigrant social capital. The results provide partial support for the immigrant revitalization perspective and warrant further methodological development and theoretical revision when studying the immigration-neighborhood crime link.enDissertationCriminologyImmigrant RevitalizationImmigrationNeighborhood CrimeSocial Disorganization
