The Impact of State-Level Firearms Laws on Homicide Rates by Race/Ethnicity

By Michael Siegel

In 2017, there were 14,542 firearm-related homicide deaths in the United States. Despite constituting only 13% of the U.S. population, Black persons made up 59% of these victims. Many states have addressed the problem of firearm-related homicide by enacting stronger firearm laws. While many studies have already been conducted on the effectiveness of various firearm laws in reducing overall population homicide rates, the vast majority of these studies do not distinguish between victims of different races/ethnicity. In failing to do so, these studies assume that state-level firearm laws produce homogeneous effects, even while Black communities continue to bear the undue burden of firearm violence. The purpose of this research was to fill this critical gap by rigorously evaluating the differential impact of state-level firearm laws on homicide rates among White, Black, and Hispanic populations. This project sought to answer two major research questions: (1) Is there heterogeneity in the effect of different state firearm laws on homicide rates by race/ethnicity? (2) To what extent are any differences in the impact of firearm laws by race/ethnicity explained by contextual differences in homicide victimization across urban vs. non-urban settings, as opposed to differences among racial groups per se?
