National Health and Aging Trends Study (NHATS)
NHATS is a new NIA-funded national survey based at Johns Hopkins. It is designed to promote scientific study of late-life disability trends and dynamics; and to advance our understanding of the social and economic impact of late-life functional changes for older people, their families, and society.

National Study of Caregiving (NSOC)
The NSOC is a national study of about 2,000 people who help older family members and friends with their daily activities. Caregivers are linked to the respondents in the NHATS.
