Washington, DC - The Centers for Disease Control and Prevention estimates that 1 in 68 children (or 14.7 per 1,000 eight-year-olds) in the United States has been identified with autism spectrum disorder (ASD), according to a surveillance summary report, “Prevalence of Autism Spectrum Disorder among Children Aged 8 Years- Autism and Developmental Disabilities Monitoring Network, 11 Sites, United States, 2010.”

According to the new report:

  • The estimated number of children identified with ASD continues to rise. This latest estimate is roughly 30 percent higher than previous estimates from CDC’s autism tracking system.
  • Some things about ASD have remained the same. For example, ASD is almost five times more common among boys than girls. White children are more likely to be identified with ASD than Black or Hispanic children. And, most children with ASD are still not diagnosed until after age 4, even though ASD can be diagnosed as early as age 2.
  • However, the picture of ASD in communities is changing. Almost half of children identified with ASD have average or above average intellectual ability (an IQ of 85 and above) compared to a third of children a decade ago.

CDC continues to be in the forefront of documenting changes in the picture of autism over time. More is understood about autism than ever before, but there is an urgent need to continue the search for answers and provide help now for people living with autism.


  • You know your child best. If you have a concern about how your child plays, learns, speaks, acts, or moves, take action. Don’t wait.

Research tells us the earlier a child with autism is identified and connected to services, the better. That’s why it’s so important for every parent to track their child’s development and act quickly if there is a concern.
