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.

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.

The group defined “mass shooting” as a gun-related crime where four or more people were shot in a public space.
