The Residential Information Systems Project (RISP) is a longitudinal study of long-term supports and services (LTSS) for people with intellectual and developmental disabilities (IDD). An annual survey of state IDD agencies is used to gather information about the settings in which LTSS recipients live, federal and state funding sources, residential setting type and size, recipient age and expenditures. A separate annual survey asks state-run IDD facilities serving 16 or more people to describe the people living in those settings. The most recent full report, released February 2023, shares data from the FY 2019 surveys. Infographics and state profiles for FY 2019 are also available.
