As the largest and most comprehensive panel study of older adults in the United States, the HRS collects a broad set of demographic, social, economic, family, behavioral, and health-related variables. This includes validated measures of cognitive function and impairment that will be of interest to researchers examining the social determinants of ADRD. The HRS is currently one of three population-based studies supported by the Analysis Core.
