Mass school shooting data from 1980s-2024, including injuries/deaths and distances to trauma centers. School shootings and casualties have risen, especially in the 2020s. "All schools" median distance to trauma center is lower than "Schools with mass shootings."
Schools with mass school shootings were located farther from level I and II trauma centers, with increasing numbers of shootings and victims since the 1980s, indicating geographic gaps in emergency trauma access. ja.ma/4ut0tNx
