In 2020, the CDC reported that approximately 1 in 54 children in the U.S. is diagnosed with an autism spectrum disorder (ASD), according to 2016 data.
1 in 34 boys identified with autism
1 in 144 girls identified with autism
Boys are four times more likely to be diagnosed with autism than girls.
Most children were still being diagnosed after age 4, though autism can be reliably diagnosed as early as age 2.
Autism affects all ethnic and socioeconomic groups.
Early intervention affords the best opportunity to support healthy development and deliver benefits across the lifespan.
There is no medical detection for autism.
