| NOTES: In the Current Population Survey (CPS), people are categorized as "work disabled" if they are receiving disability benefits (such as persons aged 0–64 who are on Medicare or Medicaid or who receive DI or SSI benefits) or if the person has a problem working (or is not working) because of illness or disability. | |||
| There was a minor change in the CPS definition of disability in 1996, but the trends in the series were well established before, and continued after, the change. | |||
