How many older people with intellectual disabilities/mental retardation are there?
Current estimates for adults age 60 and over with intellectual disabilities/mental retardation and other developmental disabilities (e.g., cerebral palsy, autism, epilepsy) range between 600,000 and 1.6 million. This population is growing rapidly, and although many persons are unidentified and the true number is not known, we can expect that by 2030, there will be several million.
