The latest data on autism spectrum disorder (ASD) from CDC's Autism and Developmental Disabilities Monitoring (ADDM) Network.


Prevalence of ASD

  • ASD is reported to occur in all racial, ethnic, and socioeconomic groups. [Read Article]
  • ASD is nearly 4 times more common among boys than among girls. [Read Article]
