The Program on Global Aging, Health, and Policy at the Dornsife Center for Economic and Social Research (CESR) conducts and supports research on aging, health and well-being of older people around the world. Our mission is to enhance the understanding of older adults’ health and well-being to contribute to evidence-based policy formulation. In close collaboration with leading researchers around the world, we seek to contribute to advance science through collecting and analyzing data on aging, health, and socioeconomic status as well as building and disseminating user-friendly population data files and tools to facilitate research on global aging.
