MONDAY, March 10, 2025 (HealthDay News) -- A startling number of Americans have witnessed a mass shooting in their lifetime, a new study suggests. About 1 in 15 adults have been present at the scene of a mass shooting, and more than 2% have been injured in one, researchers say in JAMA Network Open.

The group defined “mass shooting” as a gun-related crime where four or more people were shot in a public space. The post One in 15 adults in United States of America has witnessed a mass shooting appeared first on Talker.

About 7% of U.S. adults have been present at the scene of a mass shooting in their lifetime, and more than 2% have been injured during one, according to new University of Colorado Boulder research.

More than half of the participants who said they had been present during a mass shooting said that it had happened within the last decade, the study said.
