This study examines the relationship between state gun ownership rates and school firearm incidents (n = 1275) and injured/killed victims (n = 2026) of these incidents over a forty-year period (1980–2019). It also investigates whether child access prevention, minimum age requirements for gun purchases, and mandatory gun safety training laws are associated with fewer school firearm incidents and injured/killed victims.
Methods
Data were linked together from the School Shootings Database, State Firearm Law Database, the National Center for Education Statistics, and the US Census Bureau. State fixed effects and interrupted time series analyses were performed.
Results
State gun ownership rates declined between 1980 and 2019 while school firearm incidents generally ranged between 20 and 40 incidents before skyrocketing to 102 incidents in 2018 and 110 incidents in 2019. Findings were mixed on the relationship between state gun ownership rates and school firearm incidents and injured/killed victims. Additionally, child access prevention, minimum age requirements for gun purchases, and mandatory gun safety training laws exhibited weak and inconsistent relationships with school firearm incidents.
