The National Health and Aging Trends Study (NHATS) has released its Round 7 beta data files, which are available from the NHATS site in both SAS and Stata formats.
The site also provides an updated User Guide, Round 7 annotated instruments, and a revised crosswalk between the instruments and the codebook.
NHATS is sponsored by the National Institute on Aging with the intent to foster research that will guide efforts to reduce disability, maximize health and independent functioning, and enhance quality of life at older ages.
