Purpose of consultancy

To contribute to producing global, regional and country prevalence estimates of intimate partner violence and non-partner sexual violence.

This will entail adapting and expanding the existing statistical model, conducting consistency checks on input datasets, providing technical inputs to support responses relating to data or modelling queries from Member States or other stakeholders, investigating and fixing program bugs which may arise.


The World Health Organization's Department of Sexual and Reproductive Health and Research (SRH) includes the UNDP-UNFPA-UNICEF-WHO-World Bank Special Programme of Research, Development and Research Training in Human Reproduction (HRP). HRP is the main instrument within the United Nations system for identifying research priorities on sexual and reproductive health and rights; for promoting, conducting, evaluating and coordinating related interdisciplinary research; for collaborating with countries to build national capacity to conduct research; and for promoting the use of research results in policy making and sexual and reproductive health programmes. The Department draws on research and global expertise to set norms and standards and develop global guidelines on sexual and reproductive health and rights. More information about SRH and HRP can be found at

WHO leads the United Nations Inter-Agency Working Group on Violence Against Women Estimation and Data (VAW-IAWGED) and the production of the country, regional and global prevalence estimates on violence against women, supported by the UN Women-WHO Joint Programme on Strengthening Measurement and Building National Capacities for Violence Against Women Data (Joint Programme on VAW Data). These internationally comparable estimates contribute to global monitoring including for the UN Sustainable Goals’ (SDGs) violence related indicators (5.2.1 and 5.2.2).

The purpose of this consultancy is to provide technical support and input into the models to produce global, regional and country estimates (adapting and expanding the existing models, conducting consistency checks on datasets, providing technical inputs to support responses relating to data or modelling queries from Member States or other stakeholders, investigating and fixing program bugs which may arise e.g., from package updates.

The work is located in the Addressing needs of Vulnerable Populations Unit (AVP) in SRH/HRP which is responsible for the work on violence against women /gender-based violence, including research, data and monitoring and evaluation, development of guidance and implementation tools, and provision of specialized technical support, among others. It is supported by the UN Women-WHO Joint Programme on Violence Against Women Data started in 2018. The JP aims to ensure quality, comparable data on different forms of violence against women are available and collected over time to address national data gaps and meet policy and reporting commitments. This includes work on strengthening and dissemination of measurement and methodologies for VAW data collection and use.
