Colorado Autism and Developmental Disabilities Monitoring (ADDM) Project

Monitoring program and summary results 

The Autism and Developmental Disabilities Monitoring (ADDM) Network is a group of programs funded by the U.S. Centers for Disease Control and Prevention (CDC) to determine the prevalence of the autism spectrum disorders (ASDs) in their areas. Colorado was part of the ADDM Network until 2018.

The ADDM Network’s methodology is a multiple-source, records-based monitoring system. Its goals are to:

  • Determine the prevalence of ASD in the communities listed above.
  • Describe the population of children with ASD.
  • Compare ASD prevalence in different groups of children and different areas of the country.
  • Identify changes in ASD prevalence over time.

Colorado-ADDM was a partnership between us and JFK Partners at the University of Colorado Anschutz Medical Campus. Its goal was to provide an ongoing estimate of the prevalence of ASD among 8-year-old and 4-year-old children in metro Denver (Adams, Arapahoe, Boulder, Broomfield, Denver, Douglas and Jefferson counties).

More information about ADDM and current network sites can be found at this  CDC ADDM webpage.
