How combinations of state firearm laws link to low firearm suicide and homicide rates: A configurational analysis

Firearm violence, including both homicide and suicide, is a major public health problem in the United States (US). To decrease firearm mortality, US states have implemented laws to restrict firearm availability.

We evaluated ten state firearm laws using configurational comparative methods (CCMs) designed to uncover how multiple factors are linked to a given outcome. We applied coincidence analysis, a novel CCM, to ten firearm laws in US states in 2016, to assess how different combinations of firearm laws distinguished states with low firearm homicide or suicide rates from those states with higher rates.
