Gun Violence Facts

  • 580+ Mass Shootings in 2023

    Mass shootings have been on the rise. Between January and October 2023, there have been 587 mass shootings in 44 states, resulting in 650 people killed and an additional 2,485 injured. The number of mass shootings each year has risen about 20% year over year since 2019 (7)

  • U.S. Averages More Than 13 Mass Shootings Each Week

    In 2023, the US is averaging 13 mass shootings a week. The GVA defines a mass shooting as an event where a minimum of four victims are shot, either injured or killed, not including the shooter.

  • Assault Weapons Are Weapon of Choice for Mass Shootings

    High-capacity semiautomatics (which include assault weapons as a subset) are used between 20% and 58% of all firearm mass murders, and they are used in a particularly high share of public mass shootings. (8)

  • Assault Weapons are Made to be Deadly

    Wounds caused by assault weapons are more severe and lethal than wounds caused by other firearms, and, particularly when paired with large capacity magazines, assault weapons can injure more people more quickly. Because of this lethality, assault weapons are frequently the guns of choice for individuals who carry out horrific public attacks. An analysis of public mass shootings resulting in four or more deaths found that more than 85% of such fatalities were caused by assault rifles. (7)

How we know an Assault Weapons Ban works

Since the Federal Assaults Weapons ban expired in 2004, the number of mass shooting victims increased 2-3x

Mass shootings have also become more frequent…

…and more deadly


“When an assault weapon and/or a high-capacity magazine is used in a public mass shooting, nearly 14 times as many people are injured, and twice as many people are killed.”

-Says Dr. Kyleanne Hunter, PhD, a Marine Corps combat veteran, and Senior Political Scientist at RAND Corporation
