Summary
A new study from the University of Colorado Boulder finds that 7% of U.S. adults have witnessed a mass shooting, and over 2% have been injured in one.
Researchers define mass shootings as incidents where four or more people are shot in public spaces. With nearly 5,000 such events since 2014, experts stress the need for public health strategies to address the psychological and physical impacts.
The study highlights how mass shootings are not isolated events but a widespread issue affecting millions of Americans.
Not of it’s over an average lifespan, or even just adulthood. 50 years of mass shootings gets us a lot closer to 1/15th, even assuming some of the people have witnessed more than one.
