About The Study: This study found that higher rates of incarceration were associated with increased rates of firearm homicides among Black communities alone; this association was found to be mediated partially through the density of single-parent households in these areas, suggesting that social disorganization resulting from mass incarceration may perpetuate firearm homicides. Targeted policies addressing mass incarceration and the disparities therein may be a means of reducing urban firearm homicides.
