“In 2020, gun violence surpassed traffic accidents, cancer, suffocation, and poisoning as the leading cause of death among children and teens. That makes the US exceptional: In no other wealthy or similarly sized country is gun violence one of the top four causes of death among children and teens, let alone the leading one, according to a 2022 analysis by the Kaiser Family Foundation. That analysis also showed that the US accounts for 97 percent of all child and teen firearm deaths among its peer countries.
Most of those US deaths are caused by assault, with 3.6 children and teens per 100,000 dying on that account in 2020. By comparison, 1.7 and 0.3 per 100,000 children and teens died from firearm suicide and unintentional or undetermined firearm-related causes, respectively.
Children and teens in the US also experience ongoing secondary effects from gun violence, even if they are not injured in a shooting. Researchers at Penn Medicine found in a 2021 study of more than 2,600 shootings that there was a significant spike in emergency department visits for mental health issues among children after neighborhood shootings, with the most acute effects observed among children living closest to the site of the shooting and those who have witnessed multiple shootings.”
