The Gateway to Global Aging Data (G2G) is a platform for population survey data on aging around the world. It includes the Health and Retirement Study (HRS) the Mexican Health and Ageing Study (MHAS), the English Longitudinal Study on Ageing (ELSA), Survey of Health, Ageing, and Retirement in Europe (SHARE), Korean Longitudinal Study on Aging (KLoSA), Japanese Study on Aging and Retirement (JSTAR), Indonesian Family Life Survey (IFLS), China Health, Aging, and Retirement Longitudinal Study (CHARLS), Irish Longitudinal Study on Ageing (TILDA), Study on Global Ageing and Adult Health (SAGE), and Longitudinal Aging Study in India (LASI). G2G provides the digital library of detailed metadata and illustrative flow-charts with information about survey questions, response scales, interviewer instructions, survey skip patterns, and concordance over time. G2G helps users quickly find relevant survey questions through an intelligent search engine, cross-survey concordances, and detailed documentation. G2G facilitates cross-country analyses by providing a set of identically defined (HARMONIZED) variables on demographic, health, health behavior, financial and housing wealth, income, family structure, and employment history. Interactive graphs and tables offer a quick way to examine selected variables and compare the characteristics of older populations in more than 25 countries. G2G is located at g2aging.org.
