Violent Deaths at School and Away From School and School Shootings

(Last Updated: May 2021)
This indicator also appears under School Crime and Safety.

Between 2000–01 and 2019–20, the number of school shootings with casualties per year at public and private elementary and secondary schools ranged from 11 to 75.

Violent deaths and shootings at schools are rare but tragic events with far-reaching effects on the school population and surrounding community. This indicator first presents data on school-associated violent deaths that were collected through the School-Associated Violent Death Surveillance System (SAVD-SS), as well as data on total homicides and suicides of youth ages 5–18, collected through the National Vital Statistics System by school year. The indicator then examines data on school shootings and casualties from the K–12 School Shooting Database (K–12 SSDB) from the Center for Homeland Defense and Security.

1 A school-associated violent death is defined as “a homicide, suicide, or legal intervention death in which the fatal injury occurred on the campus of a functioning elementary or secondary school in the United States,” while the victim was on the way to or from regular sessions at school, or while the victim was attending or traveling to or from an official school-sponsored event. Victims may include nonstudents as well as students and staff members.

NOTE: “At school” includes on the property of a functioning elementary or secondary school, on the way to or from regular sessions at school, and while attending or traveling to or from a school-sponsored event. In this indicator, the term “at school” is comparable in meaning to the term “school-associated.” All data are reported for the school year, defined as July 1 through June 30. Data from 1999–2000 onward are subject to change until law enforcement reports have been obtained and interviews with school and law enforcement officials have been completed. The details learned during the interviews can occasionally change the classification of a case.

SOURCE: Centers for Disease Control and Prevention (CDC), 1992–2018 School-Associated Violent Death Surveillance System (SAVD-SS) (partially funded by the U.S. Department of Education, Office of Safe and Healthy Students), previously unpublished tabulation (November 2020). See Digest of Education Statistics 2020, table 228.10.

1 The 2017–18 data from the School-Associated Violent Death Surveillance System (SAVD-SS) are subject to change until interviews with school and law enforcement officials have been completed. The details learned during the interviews can occasionally change the classification of a case.

2 Total youth suicides exclude self-inflicted deaths among 5- to 9-year-olds. Total youth suicides include only persons ages 10 and over because determining suicidal intent in younger children can be difficult.

NOTE: “School shootings” include all incidents in which a gun is brandished or fired or a bullet hits school property for any reason, regardless of the number of victims (including zero), time, day of the week, or reason (e.g., planned attack, accidental, domestic violence, gang-related). Data in this figure were generated using a database that aims to compile information on school shootings from publicly available sources into a single comprehensive resource. For information on database methodology, see K–12 School Shooting Database: Research Methodology (https://www.chds.us/ssdb/resources/uploads/2020/09/CHDS-K12-SSDB-Research-Methods-Sept-2020.pdf). Due to school closures caused by the coronavirus pandemic, caution should be used when comparing 2019–20 data with data from earlier years. Some data have been revised from previously published figures.

1 A legal intervention death is defined as a death caused by a law enforcement agent in the course of arresting or attempting to arrest a lawbreaker, suppressing a disturbance, maintaining order, or engaging in another legal action.

2 In this indicator, the term “at school” is comparable in meaning to the term “school-associated.”

3 Data are subject to change until interviews with school and law enforcement officials have been completed. The details learned during the interviews can occasionally change the classification of a case.

4 Also defined as July 1, 2017, through June 30, 2018.

5 Total youth suicides exclude self-inflicted deaths among 5- to 9-year-olds. Total youth suicides include only persons ages 10 and over because determining suicidal intent in younger children can be difficult. For more information, see Crepeau-Hobson, F. (2010).

6 Single incidents occurring at school with a large number of school-age victims could result in large variations in the number of youth homicides at school between two years. Please use caution when making comparisons over time.

7 Due to school closures caused by the coronavirus pandemic, caution should be used when comparing 2019–20 data with data from earlier years.

8 Including other schools ending in grade 12.

9 Argument or fight between the shooter and victim prior to the shooting.

10 Shots fired by a person in a vehicle at people or another vehicle on school property.

13 Targeted at random victims with the intent to kill or injure as many as possible (e.g., fired into a crowd, shot students in the hallway or random classrooms).
