Title:Using Social Network Analysis in Gun Violence Prevention
Every year, thousands of people are killed and many more injured with a firearm in the United States. Gunshot violence is concentrated in economically and socially disadvantaged communities, disproportionately affecting young black men. In this talk, I evaluate the Chicago Violence Reduction Strategy (VRS), a programme that aims to reduce gunshot violence via a social network intervention aimed at high-risk individuals. The evaluation uses data on gun assaults in a social network of 123,506 individuals in Chicago from 2008–2014. The network is composed of co-arrest ties, which are present between two or more individuals when they have been arrested together. The model estimates the effect of direct exposure to the programme, as well as spillover effects where individuals whom are not directly exposed to the programme may experience indirect effects through network transmission. The results show a reduction in the incidence of gunshot victimization that is largely due to spillover effects. The reduction in the risk of victimization diminishes as the distance to treated individuals increases, indicating that network diffusion is critical to the efficacy of the VRS programme
