The National Archive of Computerized Data on Aging (NACDA)

NACDA is the aging archive within ICPSR, and is funded by the National Institute on Aging (NIA). We host data resources for secondary research use from data collections across the U.S., as well as some international sources. The majority of our data resources are available to the public, with registration, at no cost.
