Patterns in single- and multiple-victim school-associated homicide rates differ, and both fluctuate annually.
Single-victim homicide rates remained stable overall during 1994–2016. School-associated single-victim homicides share characteristics with youth homicides in the community, often involving racial/ethnic minorities, males aged 15–18 years, and occurring in urban areas. Firearm-related injuries were the cause of death in 247 (62.8%) and 115 (95%) single- and multiple-victim homicides, respectively. Multiple-victim incidence rates increased significantly from July 2009 to June 2018.
Evidence-based youth violence prevention options exist, including strategies that promote connections between youths and caring adults, enhance problem-solving and coping skills, and reduce risk among youths who have been violent. A comprehensive violence prevention approach is important for reducing violence on and off school grounds.
