This is a researcher contributed dataset that provides predicted cognition and dementia measures developed in Hudomiet, Hurd, and Rohwedder (2022).

Contributed projects based on HRS public data are provided by researchers who want to share their work with the research community.

This dataset contains five cognition and dementia measures:

  1. PrDem: Estimated probability of dementia of the person-year observation.
  2. PrCIND: Estimated probability of “cognitive impairment, not dementia” (CIND).
  3. PrNorm: Estimated probability of normal cognitive status (i.e., neither dementia nor CIND).
  4. Cog: Expected value of latent cognitive ability
  5. CogSd: The standard deviation of latent cognitive ability (i.e., the precision of the Cog estimate)

The measures are available for all HRS respondents above age 65 between the 2000 and 2016 waves. There are 97,629 person-year observation from 21,442 individuals.
