A/71/398 34. In 2015, the Secretary-General submitted a report to the General Assembly on action against the gender-related killing of women and girls (A/70/93), in which he reiterated the recommendations made at the expert group meeting. In a second resolution, also initiated by the Commission on Crime Pre vention and Criminal Justice and adopted by the General Assembly (resolution 70/176), on taking action against the gender-related killing of women and girls, the Assembly reiterated its call for action by Member States with the support of the United Nations. It noted that one of the every two women victims of homicide was killed by her intimate partner or a family member. The Assembly called upon Member States to strengthen criminal justice responses to the gender-related killing of women and girls; enhance international cooperation and the exchange of good practices in criminal matters related to gender-based violence; promote integrated and comprehensive strategies to prevent the gender-related killing of women and girls, which included early and continuous educational programmes, community mobilization and awareness raising, in order to counter attitudes and social factors that fostered, justified or tolerated any violence against women and girls; adopt integrated and comprehensive responses to violence against women in order to reduce risks of gender -related killing through a number of listed measures; address impunity and punish perpetrators; provide support for victims; and collect, disaggregate, analyse and report data on the gender-related killing of women and girls, according to the International Classification of Crime for Statistical Purposes endorsed by the Statistical Commission and, where appropriate, to the extent possible, involve civil society, academia, victims’ representatives and relevant international organizations. Resolution 70/176 contains stronger language in relation to data collection. In it, the Assembly requested UNODC to prepare an analytical study on the gender-related killing of women and girls at the global level, containing disaggregated data, including from relevant stakeholders, on the phenomenon to illustrate its different forms and patterns. 2. Current data collection on homicide and femicide 35. The case has been repeatedly made that the collection, analysis and sharing of relevant data are crucial for effective and coordinated measures to prevent, investigate and prosecute the gender-related killing of women. To accomplish these goals, detailed data are required to gauge the magnitude and dimensions of the problem, to establish baselines, to identify groups at high risk, to focus intervention and prevention efforts where they are needed most, to monitor changes over time, to assess the effectiveness of interventions and to address the harm to victims of violence (see A/70/93). In this regard, it has been noted that the comparability and availability of precise statistics is key to definin g the spectrum of gender-related killing in its various manifestations, causes and consequences (see ibid.). 36. There exist various sources of data and information on gender-related killing. These include administrative records of law enforcement and judicial sources and population-based sources of information, such as victimization, demographic and health surveys to estimate the exposure of women to partner and non -partner __________________ upon the report of the Secretary-General on the outcome of the intergovernmental expert group meeting on gender-related killing of women and girls (E/CN.15/2015/16), the report of the Secretary-General on action against gender-related killing of women and girls (A/70/93) and the report of the Special Rapporteur on violence against women, its causes and consequences (A/HRC/10/16). 16-16456 13/24
