In FY2010, an estimated 566,188 individuals received day or employment supports from state intellectual and developmental disability (IDD) agencies. This number grew from 458,650 in FY1999, a 23.4 percent increase. The estimated number of individuals supported in integrated employment services increased from 108,296 in FY1999 to 113,937 in FY2010, a 5.2% increase. State investment in supports continues to emphasize facility-based and non-work services rather than integrated employment services.
