how often are school shootings in the us

School shootings in the United States occur with alarming frequency. In recent years, the number of school shootings with injuries or deaths has ranged from around 24 to over 50 annually. For example, there were 51 school shootings with injuries or deaths in 2022, 39 in 2024, and 9 so far in 2025. Since the Columbine High School shooting in 1999, there have been more than 400 shootings at K-12 schools, exposing over 370,000 students to gun violence. On average, there have been about 87 school shootings per year from 2013 to 2021. The incidents vary in severity, with many involving injuries rather than fatalities, but the overall trend shows an increase in both frequency and casualties over the years. In 2023, for instance, there were a record 348 school shootings at K-12 schools resulting in 249 injuries and fatalities combined. Thus, school shootings occur multiple times per month or even weekly across the United States. This deeply troubling trend continues to impact countless students and communities.
