The Impact of Firearm Legislation on Firearm Deaths, 1991-2017


Firearm suicides and homicides are the leading cause of gun fatalities in the United States. A recent study featuring PISC Past Trainee and Senior Scholar Bernadette Hohl, PhD, evaluated the impact firearm legislation has on reducing homicide and suicide rates. Hohl and the team accessed data from the State Firearm Law Database. Varying state firearm legislatures were compared to suicide and homicide rates from 1991-2017. Results indicated that states with high levels of firearm laws had significantly reduced suicide and homicide rates. Findings indicate the role of firearm legislation to be essential in limiting gun violence fatalities in the United States.
