How does the federal government determine who has a disability?

The Americans with Disabilities Act (ADA) defines a person with a disability as someone who:

  • has a physical or mental condition that significantly limits one or more major life activities,
  • has a past history or documented record of such a condition (for example, cancer in remission), or
  • is regarded by others as having such a condition, even if it does not currently limit major life activities (for example, someone with visible burn scars).


There is no standard government approach to measuring disability, but in its American Community Survey (ACS), the Census Bureau considers a person with a disability as an individual who self-reports difficulty with walking or climbing stairs, hearing, independent living, vision, self-care, and/or cognition.
