Each year the VPC releases this report in advance of Domestic Violence Awareness Month in October. The study uses 2019 data, the most recent year for which information is available. The study covers homicides involving one female murder victim and one male offender using data from the Federal Bureau of Investigation’s Supplementary Homicide Report. The study found that nationwide, 91 percent of women killed by men were murdered by someone they knew and that the most common weapon used was a gun. Black women are disproportionately impacted by lethal domestic violence. In 2019, Black females were murdered by males at a rate of 2.34 per 100,000, more than twice the rate of 0.99 per 100,000 for white women murdered by men.
