Values in parentheses are weighted percentages (and 95% confidence intervals) derived using the HRS sampling weights to adjust for the complex design of the HRS survey.
Values for 2012 weighted percentages in Table 3b are age- and sex-standardized to the 2000 population using direct standardization.
CIND is Cognitive Impairment—No Dementia.
