The Influence of Collective Efficacy on Gang Crimes in Hollenbeck

Heidi Thielmann, University of California, Irvine

Crime within the context of a neighborhood was examined using a theoretical model of collective efficacy that incorporates social disorganization theory. Using a combination of quantitative methods of data analysis and geographic information systems, levels of gang crimes and collective efficacy are identified and mapped in eighteen reporting districts of Hollenbeck, a division of the Los Angeles Police Department located in East Los Angeles. The model was tested using regression analysis on data aggregated to the reporting district level. Contrary to the hypothesis of the study, the influence of collective efficacy on gang crimes was not significant. The results indicate that collective efficacy may not be an important factor relating to gang crimes in traditional gang neighborhoods such as Hollenbeck.
