Infrastructure Projects Led by MiCDA Affiliates

Health and Retirement Study
- The Health and Retirement Study (U01AG009740 MPIs David Weir and Kenneth Langa) designs, collects and distributes longitudinal multi-disciplinary data to support research on aging, Alzheimer’s Disease and Related Dementias (ADRD), and the health and well-being of the older population. The study has collected data from approximately 20,000 participants ages 50 and older for more than 30 years and has been replicated around the world.
- Network grants support the harmonization of the international family of Health and Retirement Studies (U24AG037866; PI David Weir) and their Harmonized Cognitive Assessment Protocol (HCAP) Studies (U24AG065182; MPIs Kenneth Langa and Lindsay Kobayashi).
- The Health and Retirement Study also co-sponsors a Research-in-Progress Seminar.

Panel Study of Income Dynamics
- The Panel Study of Income Dynamics (R01AG040213 PI Esther Friedman) has collected information from a national representative sample of families and their descendants since 1968. Its long-term measures of economic and social wellbeing have allowed unique insight into the dynamics of social and behavioral processes, increasingly in the context of an aging society. The collection of health and other aging-related data allow study of influences on late life health and wellbeing over the life course and across generations. The PSID Seminar Series is held during the academic year to provide a forum for users of the PSID data and its supplemental studies.

National Health and Aging Trends Study and National Study of Caregiving
- The National Health and Aging Trends Study and National Study of Caregiving (U01AG032947; R01AG054004; R01AG062477 MPI Vicki Freedman) are conducted in collaboration with Johns Hopkins University. The studies promote scientific inquiry into late-life disability trends and dynamics and the consequences of late-life disability for individuals, families, and society. The most recent awards fund annual collection of NHATS and NSOC through 2028. Online dashboards and a companion chartbook are available that track trends. Users can also sign up for an NHATS online course for beginners.

Contextual Data and Data Archives
- The National Neighborhood Data Archive (NaNDA; U01NR020556; 90RTHF0001 PI Philippa Clarke) is a publicly available data archive containing measures of the physical, economic, demographic, and social environment at multiple levels of spatial scale (eg, census tract, ZIP code tabulation area, county). NaNDA is also available to approved researchers in the MiCDA enclave through its Geographic Linkages Repository.
- The National Archive of Computerized Data on Aging (U24AG056918 PI James McNally) has provided research resources and data archiving services for over 35 years. NACDA enhances the availability of gerontological data by providing to locate and access relevant materials.
