Victims of K-12 school shootings U.S. 1966-2024, by situation
Between 1966 and April 18, 2024, 836 victims were wounded while 249 victims were killed during K-12 school shootings resulting from an escalation of dispute, defined as a situation in which there was a physical or verbal altercation between the shooter and the victim(s) before the shooting or where shots were fired in retaliation for a previous attack, in the United States. Indiscriminate shootings, where the shooter intends to kill as many people as possible with no particular target, have also been highlighted as a significant source of harm in K-12 schools, with approximately 550 victims either wounded or killed within the provided time period. In comparison, school shootings attributed to anger over getting bad grades or facing disciplinary measures typically lead to a scenario in which teachers or school administrators are the primary targets of school shooters. Totaling less than 100 victims, this type of situation also encompasses shootings carried out by school employees against coworkers or superiors after poor performance evaluations, suspensions, or job losses.
