About the CHDS K-12 School Shooting DataBASE
The CHDS K-12 School Shooting Database is a widely inclusive dataset documenting each and every instance a gun is brandished, is fired, or a bullet hits K-12 school property for any reason, regardless of the number of victims, time, day of the week. The database compiles information from more than 25 different sources including peer-reviewed studies, government reports, mainstream media, non-profits, private websites, blogs, and crowd-sourced lists that have been analyzed, filtered, deconflicted, and cross-referenced. All of the information is based on open-source information and 3rd party reporting.
This dataset covers incidents from January 1970 through June 2022 and can be viewed and filtered in our data map.
As part of the new Compendium effort, the CHDS K-12 School Shooting Database will become the CHDS K-12 School Shooting Data Report. The data and analysis presented in this report will be validated, academically peer-reviewed, and published annually.
