Autism Spectrum Disorder in Tennessee (2021)
The Centers for Disease Control and Prevention (CDC) announced on 12/2/21 that the estimated prevalence of children in the U.S. with autism spectrum disorder (ASD) has again increased.
Principal investigators from the Vanderbilt Kennedy Center's (VKC) Treatment and Research Institute for Autism Spectrum Disorders (TRIAD) continue to lead tracking in Tennessee through a grant from the CDC’s Autism and Developmental Disabilities Monitoring (ADDM) Network.
Tennessee is one of 11 participating states.
What We Learned in Tennessee

|1 in 51 4-year-old children (or 2%) were identified with ASD in 2018.|
|Among 8-year-old children, boys are more than 4 times as likely to be identified as girls.|
|Black children (1.2x) and Hispanic children (1.3x) were more likely to be identified with ASD by 8-years-of-age than White children.|
|More children are being evaluated for ASD at an earlier age.|
|41% of 8-year-old children identified with ASD received an evaluation by 3 years of age.|

“Year after year, we are seeing more children diagnosed with Autism. The encouraging news is that these children are getting diagnosed earlier, and that is thanks to partners like TRIAD and all early intervention professionals across the state. The earlier the diagnosis, the quicker our providers can start working with children and their families. Together, we will help them reach their goals and these children will have the childhood they deserve. A childhood that is defined by their own greatness.”
