What is a developmental disability?

Approximately two of every 100 Americans have a developmental disability. The federal government and state of Ohio define a developmental disability as a severe, chronic disability of a person that:

  • Is attributable to a mental or physical impairment or combination of mental and physical impairments
  • Is manifested before the person reaches age 22
  • Is likely to continue indefinitely
  • Results in substantial functional limitations in three or more areas of major life activity - Self-care - Receptive and expressive language - Learning - Mobility - Self-direction - Capacity for independent living - Economic self-sufficiency
  • Ohio bases eligibility for service on a person's degree of limitation in various areas of life activity.

    Based on the 2000 census showing Ohio's population to be 11,353,140 and using the national prevalence rate of 1.8%*, an estimated 204,357 people with developmental disabilities live in Ohio.

    * Estimated by Golay & Associates and suggested by the Federal Administration on Developmental Disabilities as the rate to use to extrapolate state level prevalence rates.
