“The “most dangerous place” for women around the world may be at home. More than half of female murder victims last year were killed by their partners or family members, according to a new United Nations study.

The findings were released by the U.N.’s Office on Drugs and Crime (UNODC) on Sunday to coincide with the International Day for the Elimination of Violence against Women. The report found that of 87,000 recorded female homicide cases last year, 50,000, or 58%, were committed by the victims’ intimate partners or family members. The toll equates to six women killed every hour, or 137 killed every day, by people they know.

“Women continue to pay the highest price as a result of gender inequality, discrimination and negative stereotypes,” UNODC executive director Yury Fedotov told Agence France-Presse. ‘The fact that women continue to be affected by this type of violence to a greater degree than men is indicative of an imbalance in power relations between women and men inside the domestic sphere.’”
