Autism and Developmental Disabilities Monitoring Network

The Autism and Developmental Disabilities Monitoring (ADDM) Network is a research project in the U.S. that tracks how common autism and other developmental disabilities are among children. By reviewing health and education records in different communities, it provides important data on how many children are affected, their characteristics, and trends over time. This helps experts understand the scope of these conditions, identify factors that might influence their development, and plan better services and policies to support affected children and families.
