The Residential Information Systems Project (RISP) is a longitudinal study long-term supports and services for people with intellectual and developmental disabilities. An annual survey of state IDD agencies is used to gather information about the settings in which LTSS recipients live, federal and state funding mechanisms used, residential setting type and size, age of recipients, and expenditures. A technical report is published annually describing the data from the most recent state fiscal year.  Beginning in FY 2015 technical report, the RISP technical report includes key data that had previously been described in a separate report for the Supporting Individuals and Families Information Systems Project (see the FISP website for products developed between 2011 and 2017).
