Autism and Developmental Disabilities Monitoring (ADDM) Network Sites

The Autism and Developmental Disabilities Monitoring (ADDM) Network is the only collaborative network to track the number and characteristics of children with autism spectrum disorder (ASD) and other developmental disabilities in multiple communities throughout the United States. Beginning in 2000, the ADDM Network has been tracking the number and characteristics of 8-year-old children with ASD. The program is now in its sixth phase of funding, and the ADDM Network includes fifteen funded sites and one CDC-managed site in Georgia (MADDSP).

In the current phase of funding (2023-2026), CDC is investing more than $22 million over four years to continue tracking at 11 sites previously included in the ADDM Network, while also launching activities in Puerto Rico, Indiana, Pennsylvania, and Texas (Austin and Laredo) (see table above). All 16 sites will conduct ASD surveillance activities among 4- and 8-year-old children. Nine of the sites will also track transition planning and co-occurring conditions among 16-year-old children with ASD.
