Autism Data 2020

The Centers for Disease Control and Prevention (CDC) announced on 3/26/20 that the estimated prevalence of children in the U.S. with autism spectrum disorder (ASD) has again increased.

Vanderbilt University Medical Center continues to take part in the study to determine the current prevalence of ASD through a grant from the CDC’s Autism and Developmental Disabilities Monitoring (ADDM) Network. Principal investigators from the Vanderbilt Kennedy Center's (VKC) Treatment and Research Institute for Autism Spectrum Disorders (TRIAD) found:

United States 2020

  • 1 in 54 children—An increase from 1 in 59, the 2018 CDC estimate
  • 1 in 34 boys—Boys with ASD outnumber girls 4 to 1

Tennessee 2020

  • 1 in 64 children
    • This is the second time Tennessee-specific data has been available.
    • The data documented that ASD is extremely common in Tennessee.
    • This study focused on an 11-county region surrounding Nashville.
    • Of the 11 states in the CDC ADDM Network, Tennessee’s number was ranked 8 of 11 reporting states.
    • Only 36% of children with ASD received a diagnosis before 3 years—highlighting the need for improved early detection initiatives.
