State of the States in Intellectual and Developmental Disabilities
A Longitudinal Data Project of National Significance
The State of the States in Intellectual and Developmental Disabilities project was initiated in 1982 to investigate the determinants of public spending for intellectual and developmental disabilities services in the United States. The project has developed 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.
This Longitudinal Data Project of National Significance is funded by the Administration on Disabilities, U.S. Department of Health and Human Services.
You can access nationwide longitudinal financial and programmatic trends on intellectual and developmental disabilities services by going to State Profiles.
