Dataset: National Health and Aging Trends Study (NHATS)
|Dataset Full Name||National Health and Aging Trends Study|
|Summary||The National Health and Aging Trends Study (NHATS) collects individual level information on a nationally representative sample of Medicare beneficiaries ages 65 and older through in-depth interviews. It is a longitudinal study that began in 2011 with yearly follow-up of each participant. NHATS is designed to collect data on late life trends, functional decline, and impact of disability on socio-economic dynamics of individual functioning, and burden on family and society. The data include a broad set of activities including self care, care giving, environment, technology usage, types of mobility device, early life status, household, income, medical, and participation in productive/social activities.|

The NHATS sample is drawn from the Medicare enrollment file, oversampling the oldest age groups and Black non-Hispanic persons. In 2011, 96% of persons ages 65 and older in the U.S. were Medicare beneficiaries.
Replenishment sampling planned for ongoing waves. Includes unique variables regarding environment, modification, accommodations, care giver burden, information on early life, and burden of disability on families, and society.
71% response rate (wave 1). Validated procedure between self-reported and performance-based measures.
Restricted data includes NHATS geographic data and Medicare data linked to NHATS sample person.
|Limitations||Very limited baseline biomarker data.||Data Details|
