The Rarity of Female Mass Shooters.
Female assailants in mass shootings in the United States are extremely rare, with only four out of 172 shootings involving at least four victims over the last five and a half decades being committed by women or girls. This reflects a broader trend of gender disparities in homicide cases, where between 80 and 90 percent of all offenders are men. The archetypical mass shooter is young and male, but there have been several high-profile outliers in recent years. The Nashville shooting on Monday was committed by a woman, making it a rare occurrence.
