The document introduces the Global Health Data Exchange (GHDx), a global health data catalog created by the Institute for Health Metrics and Evaluation (IHME) to increase transparency and access to population health data. GHDx aims to be an intuitive resource that connects data users with producers. It contains a broad range of health-related data types from multiple sources and allows users to search for data by geography, time period, and keyword. Maps on GHDx will also identify areas lacking sufficient data coverage. The ultimate goal is to make health data more accessible and usable to support better health decisions and evidence-based policies.
