This study examined relationships between variation in child and adolescent firearm mortality by state and the following variables: childhood poverty rate, percent single parent families, percent population that is African American, percent population that is Hispanic, percent students carrying a gun, percent students carrying a weapon, percent students feeling unsafe, percent students feeling sad/hopeless, percent students academically at-risk, percent students involved infighting, percent students engaging in binge drinking behavior, violent crime rate for youths, individual gun laws in each state, prevalence of firearm ownership, and percent residing in urban area. Stepwise regression was calculated and one independent variable, prevalence of firearm ownership in the state, emerged as a significant predictor of child and adolescent firearm mortality. This variable predicted 47% of the variance from state to state in the child and adolescent firearm mortality. Schools need to address firearm safety and advocate for elimination of firearms accessible to youth.
