This study is one of EIGE’s initiatives to assist Member States in collecting high-quality and comparable data on violence against women. The administrative collection within the police and justice sectors of data on intimate partner violence is crucial, as these sectors are the most relevant for ensuring justice for women and safeguarding their right to live without violence. Across Member States, great discrepancies exist between the police and justice sectors in relation to the methods employed to collect data, the quality of the data collected and how it is stored, shared and made publicly available.. .EIGE’s recommendations propose a number of solutions to improve the quality and availability of data on violence against women, and reflect the fact that there is still a severe lack in coordinated and comprehensive recording of offences across the police and justice sectors. EIGE’s study reveals that, despite the challenges, Member States are making efforts to improve and modernise their data collection practices and systems for cases of gender-based violence.
