Research Tools: Center for Homeland Defense and Security Releases Comprehensive Database of School Shootings in America

From the HSDL Blog:

Thirteen hundred shootings have occurred in the U.S. since 1970 at schools serving children in grades kindergarten through 12th (K-12), according to a research project conducted by the program for Advanced Thinking in Homeland Security at the Center for Homeland Defense and Security at the Naval Postgraduate School.

The K-12 School Shooting Database is an interactive and live database that compiles all incidents “in which a gun is brandished, 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.”

An accompanying report on the research and methodology used to develop the database explains that the definition of what constitutes a school shooting is often nebulous and may result in the exclusion of unique incidents.
