What actually causes mass shootings? The truth is much more complicated than the media or politicians like to let on. We were curious, so we started studying the subject.
Our latest report examines common factors among mass shooters. Here are the highlights in that report:
- Between 1966 and 2025, 81.2% of shooters were in documented crisis before the event.
- While 51.0% of mass shooters had prior symptoms of mental illness, 68.2% had a history of domestic violence or targeted at least one member of their family.
- Gun ownership has remained stable (30%-32% of the U.S. population) between 1980 and 2025, while mass shootings have increased by 126.0%.

We also covered myths about gun control and mass shootings, as well as other factors. Please read at Ammo.com and share!
