How many people are affected by autism?

Researchers don't know exactly how many people in the United States have autism spectrum disorder (ASD). The latest estimates suggest that:

  • About one out of every 68 children in the United States currently has autism.1

The CDC is the government agency that studies how many people have autism and other diseases. Visit the CDC website for more information on how many people have ASD: http://www.cdc.gov/ncbddd/autism/data.html

  • Is ASD more common now than it was in the past?
