Founded in 1968, the Panel Study of Income Dynamics PSID is the world’s longest-running household panel survey. It has made way for the study of dynamism in social and behavioral processes, resulting in over 4,000 peer-reviewed publications. The National Science Foundation, the study’s lead sponsor, named PSID as one of its 60 most significant innovations.

The Demography of Aging, Disability and Care program focuses on population aging, disability, and long-term care and related measurement and survey issues. The program provides leadership for several national studies of late-life disability and care. The program also supports the Michigan Center on the Demography of Aging (MiCDA), one of 15 centers funded by the National Institute on Aging (NIA) to advance research on the demography of aging.
