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 reduce disability, maximize independent functioning, and enhance quality of life at older ages. Online dashboards and a companion chartbook track trends. The supplemental National Study of Caregiving (NSOC) is conducted periodically 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.

NHATS has created an online course for beginners, available through the Michigan Center on the Demography of Aging (MiCDA).

This self-paced set of modules is designed for researchers who are learning to use the National Health and Aging Trends Study (NHATS). There is an optional module for learning to use the National Study of Caregiving (NSOC). 

The workshop is organized into three sections that take approximately 4-5 hours altogether to complete: Getting to know NHATS; Learning to use NHATS; and Using NHATS.

New Procedures for Requesting and Accessing NHATS-CMS Linked Data5/19/2022

New procedures for obtaining restricted NHATS-CMS linked files have been posted. NHATS-CMS linked data files will now be made available through the Health and Aging Data (HaAD) Enclave.  A few key changes:
   •    The HaAD Enclave is accessible from the applicant's institution or other specified location; research teams may share directories across institutions
   •    DUAs will be required with JHU and NIA (rather than CMS); Federal funding is no longer required to apply
   •    Claims and assessment files are available through 2021 with more timely and frequent updates expected than in the past
   •    Output will be reviewed by NHATS for disclosure risk before removal from the enclave  
For more information, please see "Obtaining CMS Data for the National Health and Aging Trends Study (NHATS)".
