The Global Health Data Exchange (GHDx) is a new data catalog for demographic, public health and global health data. It was developed by the Institute for Health Metrics and Evaluation (IHME) at the University of Washington to address a key issue for global and public health analysis, which is a lack of knowledge about data and access to data. The GHDx is the first – and currently the only – data catalog that focuses on health-related data on a global scale.  They are making efforts to build the broadest and most in-depth data catalog, and aim to be the go-to source for information about data for researchers, analysts, policy makers and others in the global health space. The GHDx improves data discoverability by providing a user-friendly, validated and searchable data catalog for global health, demographic, and other health-related datasets, including censuses, surveys, health records, vital statistics, and administrative data. The GHDx also aims at improving access to data by serving as a platform for data owners to share their data with the public. All of IHME’s search results are available for download, and IHME invites others to distribute their data through the GHDx.
