Welcome to the website for The State of the States in Intellectual and Developmental Disabilities Project, administered by the University of Colorado, and funded in part by the Administration on Disabilities.
Established in 1982 to investigate the determinants of public spending for intellectual and developmental disabilities (IDD) services in the United States, the Project has established a 40-year record of revenue, spending, and programmatic trends in the 50 states, the District of Columbia, and the United States as a whole. Analysis of the rich detail of the data base demonstrates the impact over time of federal, state, and local government fiscal policy. The data illustrate important service delivery trends in the states in community living, public and private residential institutions, family support, supported employment, supported living, and Medicaid Waivers. Demographic data include general population, personal income, and total state budget.
Financial and programmatic trends in the United States are presented in a series of 11 books. The most recent 11th Edition is The State of the States in Intellectual and Developmental Disabilities: 2017, by David Braddock, Richard Hemp, Emily Shea Tanis, Jiang Wu, and Laura Haffer. The book is available for purchase from AAIDD by calling 202-387-1968, or contact us directly.
The State of the States Project has produced over 300 publications. A list of selected project publications is available on this web site. The Project’s research findings have been disseminated in over 500 presentations delivered in 45 states and seven foreign countries. Here are examples from China and Alberta, Canada.
