ADDM Network Overview
The ADDM Network is a group of programs funded by the Centers for Disease Control and Prevention (CDC) to determine the prevalence of the Autism Spectrum Disorders (ASDs) in United States communities. The ADDM sites collect data using the same surveillance methods, which are modeled after CDC’s Metropolitan Atlanta Developmental Disabilities Surveillance Program (MADDSP). Its goals are:

  • To provide baseline data about ASD prevalence (how common ASDs are in a specific place and time period).

  • To describe the population of children with ASDs.
    To compare ASD prevalence in different groups of children and different areas of the country.

  • To identify changes in ASD prevalence over time.

  • To understand the impact of autism and related conditions in US communities.

ADDM Results
The ADDM Network’s first two ASD prevalence reports were released in the February 9, 2007, issue of the Morbidity and Mortality Weekly Report Surveillance Summaries

ADDM Current Phase (2006-2010)
CDC currently funds a total of 10 ADDM sites and participates as the 11th. Sites in the following states participate as part of the ADDM network:

Alabama (PDF), Arizona (PDF), Colorado (PDF), Florida (PDF), Georgia/CDC (PDF), Maryland (PDF), Missouri (PDF), North Carolina (PDF), Pennsylvania (PDF), South Carolina (PDF), Wisconsin (PDF)

ADDM Phase 1 (2000-2006)
ADDM’s first phase included funding for up to 16 sites.  These sites include the current phase list above plus Arkansas, California, New Jersey, Utah, and West Virginia.
