Reductions continue in populations of large state facilities for persons with intellectual and developmental disabilities (ID/DD). Table 1 presents the average daily populations of large state facilities (with 16 or more residents and staffed by state employees) by state in 5-year intervals beginning in 1980. Average daily population refers to the sum of each day's resident census divided by 365 days. As shown in Table 1 and Figure 1, between 1980 and 2005, the average daily populations of large state facilities for persons with ID/DD decreased by 69.2%. Reductions were less than 50% in 8 states; they were 100% in 9 states. The average daily populations of large state facilities decreased by 63.1% between 1985 and 2005, by 52% between 1990 and 2005, and by 36.6% between 1995 and 2005. In the 1985–1995 decade, large state facility populations decreased by 41.8%, a somewhat higher rate than the 36.5% decrease in the subsequent 1995– 2005 decade. In terms of actual populations, the decrease of 45,852 average residents between 1985 and 1995 was much greater than the decrease of 23,328 average residents between 1995 and 2005. Between 2000 and 2005 state institution populations decreased by 15.5% (7,438 individuals). In subsequent 5-year periods, state institution populations decreased by 16.4% (1980–1985), 23.2% (1985–1990), 24.4% (1990–1995), 24.9% (1995– 2000) and 15.5% (2000–2005). Between 2000 and 2005, every state operating one or more large state facilities decreased their institutional populations, with decreases of more than 40% in Alabama, Delaware, Indiana, and Nevada. As part of these trends. there were 7 closures of state institutions in 2005. The annual average of 5.5 closures in 2004– 2005 was greater than the annual average of 3.5 between 2000 and 2003, but less than the average of 7.75 between 1996 and 1999. In general depopulation of state institutions continues, but at a slower rate than in previous periods. (Source: Prouty, R., Smith, G., & Lakin, K.C. (Eds.). (2006).
