In the two years after the Parkland, Fl., school massacre that left 14 students and three teachers dead, at least 2,641 kids 18 and younger have been killed with guns, The Trace reports. That figure, based on data from the Gun Violence Archive, excludes most suicides, those killed in police-involved shootings, and those who were killed in the course of fatally wounding someone else. The count may be missing nearly 2,000 school-age children, because the archive primarily culls its information from media sources, and the vast majority of incidents don’t make the news. The U.S. Centers for Disease Control and Prevention, which gets mortality data from death certificates, says 1,003 people aged 18 and younger died by gun suicide in 2018.

Most victims were killed in community gun violence, domestic violence, drug homicides, unintentional discharges, and stray bullets. Only a small fraction of the victims died in school shootings like the one in Florida. The Trace assembled a team of 10 teen journalists who were able to flesh out the details on 85 young victims, most of them minority teenagers between the ages of 16 and 18.
