An Examination of US School Mass Shootings, 2017–2022: Findings and Implications

OBJECTIVES: Gun violence in the USA is a pressing social and public health issue. As rates of gun violence continue to rise, deaths resulting from such violence rise as well. School shootings, in particular, are at their highest recorded levels. In this study, we examined rates of intentional firearm deaths, mass shootings, and school mass shootings in the USA using data from the past 5 years, 2017–2022, to assess trends and reappraise prior examination of this issue. METHODS: Extant data regarding shooting deaths from 2017 through 2020 were obtained from the Centers for Disease Control and Prevention, National Center for Injury Prevention and Control, the web-based injury statistics query and reporting system (WISQARS), and, for school shootings in particular (2017–2022), from Everytown Research & Policy. RESULTS: The number of intentional firearm deaths and the crude death rates increased from 2017 to 2020 in all age categories; crude death rates rose from 4.47 in 2017 to 5.88 in 2020. School shootings made a sharp decline in 2020—understandably so, given the onset of the COVID-19 pandemic and subsequent government or locally mandated school shutdowns—but rose again sharply in 2021. CONCLUSIONS: Recent data suggest continued upward trends in school shootings, school mass shootings, and related deaths over the past 5 years. Notably, gun violence disproportionately affects boys, especially Black boys, with much higher gun deaths per capita for this group than for any other group of youth. Implications for policy and practice are provided.
