Many OECD governments regularly identify violence against women as the top gender equality issue their country faces. Yet in all countries, addressing this multifaceted issue presents serious governance and implementation challenges as victims/survivors have complex needs both during and after experiences of violence. Different service delivery providers such as health, justice, housing and social protection must work together seamlessly – across governmental and non-governmental providers – to provide an effective response. This report presents a stocktaking of OECD governments’ efforts to integrate service delivery to address the most prevalent form of gender-based violence against women: intimate partner violence. It presents an overview of different strategies for coordinating key services commonly offered in OECD countries: healthcare, justice, housing, child services, income support, and preventative programmes to stop the reoccurrence of violence. Based on extensive feedback from 35 out of 38 OECD countries and a consultation with non-governmental service providers, this report identifies best practices and investigates the barriers to resolving one of the most pressing human rights issues in OECD countries today.
