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.

In America, mass shootings dominate headlines, framed by statistics and brief moments of “thoughts and prayers”. Yet behind the numbers lies an even more unsettling reality: nearly 7% of U.S. adults have been directly exposed to a mass shooting.

Overall, 6.95 percent of U.S. adults report being present at the scene of a mass shooting, and 2.18 percent sustained physical injuries during these incidences, according to a study published online March 7 in JAMA Network Open.
