About NHATS & NSOC

Begun in 2011, the National Health and Aging Trends Study (NHATS) conducts annual in-person interviews with a nationally representative sample of Medicare beneficiaries ages 65 or older. Designed as a platform for scientific study of late life disability trends and trajectories, NHATS fosters research to guide efforts to reduce disability, maximize health and independent functioning, and enhance quality of life at older ages. Periodically caregivers to NHATS participants are interviewed in the supplemental National Study of Caregiving (NSOC) to provide the perspective of family and friends who help older adults experiencing limitations in daily life. Support for NHATS and NSOC is provided by the National Institute on Aging.
