The Residential Information Systems Project (RISP) is a longitudinal study of long-term supports and services (LTSS) that people with intellectual and developmental disabilities (IDD) receive. 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.  The RISP report includes data from the Families Information Systems Project starting from the fiscal year FY 2015 report. The current report is for FY 2018.

On July 12, 2021, three Administration for Community Living grantees – The Residential Information Systems Project (RISP),, and The State of the States in Intellectual and Developmental Disabilities – released 30 Years of Community Living for Individuals with Intellectual and/or Developmental Disabilities . Featuring infographics, photos, and accessible language, as well as personal perspectives on community living and inclusion shared by people with intellectual and/or developmental disabilities (ID/DD) who served as advisors to the project, the free digital book explores the evolution of integration and inclusion of people ID/DD in American society PDF . The book was written collaboratively by the directors of three longitudinal studies funded by ACL’s Projects of National Significance program.
