This website provides researchers access to data, documentation and other resources for the National Health and Aging Trends Study (NHATS) and the National Study of Caregiving (NSOC).
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.

Accounting for Sample Design in NHATS and NSOC Analyses: FAQs6/22/2020
We are pleased to present a new technical paper that answers frequently asked questions about how to account for the complex sample design of NHATS and NSOC in analyses. Topics covered include conducting cross-sectional analyses with NHATS and NSOC, conducting longitudinal analyses in NHATS, and an overview of weights. Example Stata and SAS code is provided. You can find the new paper here.
NSOC User Guide Update3/2/2020
We have updated the NSOC I-III User Guide to include derived variables for the NSOC III longitudinal file and a new data notice regarding an inconsistency in derived variables indicating the number of people living in the caregiver’s household. More information can be found in the
