A/HRC/7/6 page 18 forms of murder of women - femicide - that fit the definition in the Secretary-General’s study: murder in the context of intimate partner violence; sexual murder; killings of prostitutes; killings in the name of honour; female infanticide; and dowry deaths. A second proposed international indicator is to create a femicide index, and would require sex disaggregating current homicide data, alongside developing coding for “sex-based” categories. 65. While some initial investment will be needed to develop and apply the new categories, this can rapidly become a routine process providing significant purchase on not only transnational patterns but also local variations. Challenges which will require more thought involve the extent of unidentified maternal deaths and suicides which are attributable to violence against women, and whether the “missing women”, falling sex ratios, constitute a form of violence against women. 66. The second outcome indicator is the trend in female deaths due to femicide (using a national femicide index). 3. Social tolerance indicator 67. If violence against women is to be eliminated, the need to address factors that promote or constrain it becomes critical. Tolerance of such violence creates cultural contexts in which it can continue unabated and States fail to act with due diligence. From a human rights perspective, this is a situation where the violations of rights can continue unchallenged. We need a deeper understanding of the ways in which violence is structured and sustains current gender hierarchies: while women are increasingly willing to name and challenge violence against them, men’s perceptions and actions appear more resistant to change. This requires an emphasis on surveying these matters, either within prevalence surveys if they include male respondents, or through modules developed for inclusion in recurrent social attitude surveys. Questions probing understanding, awareness, levels of tolerance, whether respondents know someone who has been victimized, and willingness to intervene/report are the foundation of such measures. 68. The third outcome indicator is evidence of decreasing tolerance of violence against women (as measured by national surveys and analysed across key demographics). C. Indicators for State responses 69. Developing indicators on State response to violence against women is somewhat less complex than measuring violence, because there are clear responsibilities set out in international law: to prevent, protect, prosecute and provide compensation. There is also no academic debate on the parameters and approaches involved. 70. The indicators proposed here will allow individual countries to track their own progress over time. They may also give international monitoring mechanisms, such as the Committee on the Elimination of Discrimination against Women, a framework of benchmarks to take into account when considering State responses.
