Projections of Ohio’s Population with Intellectual and/or Developmental Disabilities by County, 2010-2030

Our projections of the population with developmental disability are based on our population projections, above, and the estimated prevalence of disability, defined as having a diagnosis of Intellectual Disability (ID) or Developmental Disability (DD) and needing assistance of another person not only with ADLs but also with communication, independent living, and economic independence. Persons with very low IQ level are considered having severe or profound intellectual disability requiring 24-hour supervision. Again the definition of severe disability employed here is matched with Intermediate Level of Care for people with mental retardation or developmental disabilities (ICFMR) (OAC: 5101:3-3-15.3).
