In the aftermath of mass shootings and other gun-related tragedies, there is often a surge of interest on the part of community leaders, social-science researchers, and elected officials to root out the causes of gun violence in an effort to prevent such tragedies from occurring again. Any study into the causes of gun violence is necessarily complicated, however, as there are innumerable factors that contribute to the nature and prevalence of gun-related violence in any community.

Despite this complex web of factors that influence the rate of gun violence, this report finds a clear link between high levels of gun violence and weak state gun laws. Across the key indicators of gun violence that we analyzed, the 10 states with the weakest gun laws collectively have an aggregate level of gun violence that is more than twice as high—104 percent higher, in fact—than the 10 states with the strongest gun laws.
