Because domestic violence occurs behind closed doors, it’s often regarded as a private matter, and the magnitude of the problem remains hidden. In the United States one in four women is a victim of physical domestic violence at some point in her life, and homicides of intimate partners are on the rise after decades of decline. Almost two thousand women were killed by men in the U.S. in 2017. Around the world an average of 137 women are killed each day by their partners. The United Nations Office on Drugs and Crime has declared home the “most dangerous place for women.”
