The Gateway to Global Aging Data (g2aging.org) is a data and information platform developed to facilitate longitudinal and cross-country analyses on aging, especially those using the family of Health and Retirement Studies (HRS) around the world. To further this effort, the Gateway provides searchable metadata, extensive cross-survey documentation, downloadable harmonized microdata with variables standardized across surveys, and graphs and tables that enable users to instantly compare variables of interest over time, across countries, and against macro-level contextual information at no cost.
