Violent incidents in schools have been a near-constant concern since Columbine High School, though it has been an issue dating back much further. According to the Center for Homeland Defense and Security’s (CHDS) database on Shooting Incidents at K-12 Schools, between 1970 and June 2022 there were 2069 shootings resulting in 684 fatalities and 1937 injuries. Education Week tracks school shootings and as of August 2023, there have been 27 school shootings that resulted in either death or injury. The FBI publishes annual reports for active shooter incidents, though, unlike other shootings, they use very specific data criteria. These comprehensive reports are available online but data on incidents per year in educational facilities and numbers of killed/wounded can be seen below.
