Dataset Summary
The Longitudinal Studies of Aging are two nationally representative studies of elders from 1984-1990 (LSOA I) and 1994-2000 (LSOA II). Conducted as a spinoff of the National Health Interview Study (NHIS), the LSOAs contain information on a variety of physical, cognitive and social patient characteristics, including medical conditions, health services utilization, physical and social functioning, living arrangements and financial status, and more. In addition, data in LSOAs have been merged with information from the National Death Index to provide dates and causes of death. Data were collected by in-person interview for the baseline assessment and by telephone for follow-up interviews. Data are available for free upon request.

Links to other datasets
Data from the LSOA surveys are linked to death certificate data from the National Death Index. This includes a public-access file with limited data, and a restricted-access file with more in-depth information.
