Intimate partner violence (IPV)—physical and/or sexual violence by a current or former partner—is an issue that women in all regions and all countries experience. Globally, approximately one in three women who have ever been in a relationship have experienced IPV. Women face a greater risk of violence from an intimate partner than from anyone else. This brief presents data to help policymakers and others understand the nature and extent of the harm caused by IPV, especially as it relates to women’s reproductive health, family planning, and autonomy, and highlights opportunities for action. Policymakers can combat IPV and its consequences by promoting integrated policies and dedicating financial resources to support systems, programs, and services to address the intersection of IPV, health, and women’s empowerment.
