Use of State Institutions for People with Intellectual Disabilities in the United States (2005). Nelis, T. & Rizzolo, M.

The first institutional program in the United States for people with intellectual disabilities was opened in 1848. It was designed to teach skills to people so they could return to the community. The number of people living in these institutions grew quickly and by 1967 there were 194,650 people living there.

For almost 40 years, the number of people in state institutions has been going down. More people are getting support in the community. However, in 2004, there were still 41,214 people with intellectual disabilities living in state-operated institutions across the United States (see table on right). Alaska, District of Columbia, Hawaii, Maine, New Hampshire, New Mexico, Rhode Island, Vermont, and West Virginia are not listed in the table because they have no state-operated institutions.

Today, people with intellectual disabilities can get residential support in many different kinds of places. The chart on the next page shows how many people live in each kind of setting.
