Gender data is a powerful lever for global progress, but its collection, analysis, and use remains chronically under-resourced worldwide—hindering progress towards gender-transformative sustainable development and more effective policymaking. Changing the status quo will necessarily require political will, yet the political environment surrounding gender data remains poorly understood. This research, conducted in partnership with Local Development Research Institute (LDRI) and FemDev Consulting across 30 countries, maps the contours of this environment as a critical first step toward developing effective advocacy strategies that incentivize greater political prioritization, championship, accountability, and resourcing for gender data.
