  1. Values are weighted percentages, with 95% confidence intervals in parentheses, derived by using the HRS respondent population weights of each year to adjust for the sampling design of survey.
  2. * P value < 0.001, derived from the Wald chi-square tests which were performed to examine group differences in proportions of characteristics across years of survey. P-values refer to whether the proportions or characteristics were significantly different among groups between years.
  3. † P value = 0.01.
