Cognition Data

Measurement of cognition has been part of the core HRS survey since the beginning in 1992. Two separate supplemental studies provide in depth cognition measurement. Two researcher contributed datasets using the core data are also available.

These sources are listed below with relevant documentation. The cognition data in the core are available as a part of the public data. The HCAP and ADAMS data are available as sensitive data products, which requires an extra step to access.
