^a P value from Wald F tests testing for any differences across groups excluding missing/unknown.

^b Overall percentages are presented as unadjusted and age-standardized to the 2000 US standard population. Percentages were age-standardized using the following age groups: 50–64, 65–75. Percentages by sociodemographic and other variables are unadjusted.

^c Estimates suppressed because they did not meet NCHS standards for reliability (8).

^d P value reflects differences between Hispanic and non-Hispanic groups.

^e Information about adults from other Hispanic origin or ethnicity groups is not available in the NHIS public-use file.

^f Family income as a percentage of the federal poverty threshold, and multiply imputed by NCHS when missing (5,9).

^g Includes 4 groups based on the 2013 NCHS Urban–Rural Classification Scheme for Counties (5,10).
