About Us

Welcome to the website for the State of the States in Developmental Disabilities Project, administered by the University of Colorado, and funded in part by the Administration on Intellectual and Developmental Disabilities.

Established in 1982 to investigate the determinants of public spending for intellectual and developmental disabilities (I/DD) services in the United States, the project now maintains a 39-year longitudinal 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 reveals the impact over time of federal and state fiscal policy, and illustrates important service delivery trends in the states in community living, public and private residential institutions, family support, supported employment, supported living, Medicaid Waivers, demographics, and related areas.

These financial and programmatic trends are presented in a series of books. The most most recent is The State of the States in Intellectual and Developmental Disabilities: Emerging from the Great Recession, by David Braddock, Richard Hemp, Mary C. Rizzolo, Emily Shea Tanis, Laura Haffer, and Jiang Wu. The book is available for purchase from the AAIDD Bookstore or by calling 301-604-1340. Self-advocates, families, state I/DD agencies, DD Councils, Protection and Advocacy Organizations, and State Arc Chapters should e-mail us at This email address is being protected from spambots.

As noted in our Welcome and What's New pages, new Fiscal Year 2014 and 2015 data are now under review by States IDD Agency Directors, and will be posted on our State Profiles and Create a Chart website pages.

Longitudinal data for fiscal years 1977-2015 will soon be available on the State Profiles page (data now through FY 2013). The State Profiles presenting six pages of data on I/DD spending, revenue and other program trends in each state and DC will be updated through FY 2015 as well.

Customized, state-by-state comparative data through 2015 will be available on Create a Chart.

The State of the States project has produced over 190 publications. A list of selected project publications is available on this web site.

The project's research findings have been disseminated through an extensive program of more that 475 presentations delivered in 45 states and seven foreign countries. Recent examples from China and Alberta, Canada.
