| b From 1976 to 1994, the 1977 OMB Standards for Data on Race and Ethnicity were used to classify persons into one of the following four racial groups: White, Black, American Indian or Alaskan Native, or Asian or Pacific Islander. For data from 1999 to 2004, the revised 1997 OMB standards were used. Persons could select one or more of five racial groups: White, Black or African American, American Indian or Alaska Native, Asian, and Native Hawaiian or Other Pacific Islander. Data from 1999 onward are not directly comparable with data from earlier years. Persons of Mexican origin may be of any race. The National Health and Nutrition Examination Survey (NHANES) sample was designed to provide estimates specifically for persons of Mexican origin and not for all persons of Hispanic origin. |
| c Estimates are unstable because they are based on a small number of persons (relative standard error greater than 30 percent). |
