This study examined 64 school shooters who committed multi-victim attacks in the United States during the years 1966 through 2015. Results include demographic analysis of age, venues of attack, racial/ethnic identity, magnitude of attacks, and frequency of perpetrator suicide. Data is provided for the sample as a whole, as well as for different time periods to highlight trends over time. Notable results include numerous changes in post-Columbine attacks, including greater age range of perpetrators, more perpetrators who are not white males, increased fatalities, and increased suicide rates.
