A woman who survived a mass shooting in Highland Park, Illinois, in 2022 made a passionate plea for gun safety legislation in front of TV cameras after a mass school shooting in Nashville, Tennessee.

After a police official finished a briefing on the deadly school shooting that left three 9 year olds and three adults dead, Ashbey Beasley stepped in front of the microphones.

“How is this still happening? How are our children still dying and why are we failing them? Gun violence is the number one killer of children and teens — it has overtaken cars,” Beasley said March 27.

Beasley told PolitiFact that she was in Washington, D.C., on March 24 to attend the Generation Lockdown rally, where activists and lawmakers gathered to support an assault weapons ban, and then traveled to Nashville to see family and a friend. Beasley became a gun safety activist after she and her son, then 6 years old, survived the Highland Park mass shooting during a July 4 parade.

After previous mass shootings, including at a school in Uvalde, Texas, we fact-checked U.S. Sen. Chuck Schumer, D-N.Y., who said that “the leading cause of death among children is a firearm.” We rated his statement Mostly True based on analyses of 2020 federal data. The same finding holds true for 2021 data on children and teenagers ages 1 to 19.

Data shows firearm deaths surpassed motor vehicle deaths

Beasley told us she is careful to say “children and teens” because she has heard people dispute the statement when someone refers only to “children.” She told us she got the 2021 statistic from Everytown for Gun Safety, a gun control advocacy group.

Generally, researchers say they don’t include infants in their analyses because of certain conditions unique to babies.

It is technically correct to say that firearms are the leading cause of death for people aged 1 to 19 when they are combined into a single group, said Veronica Pear, an assistant professor in the Violence Prevention Research Program at University of California, Davis.

“This is an eye-catching and powerful statistic, so I get why people use it,” Pear said.

But Pear warned that someone could wrongly interpret the statement to mean that firearms are the leading cause of death for each individual age within the 1 to 19 range.

Firearm-related deaths are exceedingly rare among babies and young children, while teenagers, especially older teenagers, have very high rates of dying from firearm-related injuries, Pear said.

“When all these ages are pooled together, the very high rates among teens are swamping the very low rate among young kids, such that firearms are the leading cause of death for the group as a whole,” Pear said.

The Nashville shooting occurred at The Covenant School, a small private Christian school serving preschool through sixth grade. If we look at death data for ages 3 to 12, it shows firearms as the sixth leading cause.

However, researchers we interviewed said it is valid to look at firearm deaths for ages 1 to 19. David Hemenway, director of the Harvard Injury Control Research Center, told us there is no official definition of “children.”

Hemenway co-wrote a perspective article for the New England Journal of Medicine about causes of death for people ages 1 to 24.

“For more than 60 years, motor vehicle crashes were the leading cause of injury-related death among young people. Beginning in 2017, however, firearm-related injuries took their place to become the most common cause of death from injury,” the article said. “This change occurred because of both the rising number of firearm-related deaths in this age group and the nearly continuous reduction in deaths from motor vehicle crashes.”

The CDC cites the 15 leading causes of death for people ages 1 to 19, but it does not pluck out firearm deaths. This data shows the top causes of death are accidents, homicide and suicide — all cagetories that include some firearm-related deaths.

The CDC does not classify firearms as a cause of death, but rather as a mechanism by which death occurs. “So, while our data does not allow us to say that firearms are the leading cause of death for this age group, it does show that firearms are the leading mechanism of injury mortality,” Brian Tsai, a CDC National Center of Health Statistics spokesperson, told PolitiFact.

Patrick M. Carter, co-director of the Institute for Firearm Injury Prevention at the University of Michigan, and Philip Cook, a professor emeritus at Duke University and gun researcher, both told us they agree it is accurate to say that in the 1 to 19 age category firearms are the leading cause of death.

PolitiFact ruling

Beasley said, “Gun violence is the number one killer of children and teens — it has overtaken cars.”

CDC data for 2021 shows that for people ages 1 to 19, firearm-related deaths ranked No. 1, followed by deaths from car accidents.

That’s for the age range as a whole; it is not the leading cause of death for each age in that group. Firearm-related deaths are far more common among older teenagers than among young children.
