On April 15, 2025, the Centers for Disease Control and Prevention (CDC) published new survey data from 2022 that shows the prevalence of autism spectrum disorder (ASD) in children is increasing. In other words, autism is more common than ever. One in 31 children now have autism, a significant rise in only two years when the prevalence was 1 in 36.
When you consider there are over 71 million children in the U.S., the impact of autism on children and their families can’t be understated.

How the new rate of autism was identified
The CDC surveyed the Autism and Developmental Disabilities Monitoring (ADDM) Network to estimate the prevalence and characteristics of autism in children who are 4 and 8 years of age. The network was also used to monitor the age at which children are being identified as having autism.
The ADDM Network was comprised of 16 surveillance sites located in Arizona, Arkansas, California, Georgia, Indiana, Maryland, Minnesota, Missouri, New Jersey, Pennsylvania, Puerto Rico, Tennessee, Texas, Utah, and Wisconsin.
Children in the latest CDC survey were classified as having ASD if they ever received at least one of the following:
- An ASD diagnostic statement in a comprehensive developmental evaluation
- Autism special education eligibility
- An ASD International Classification of Diseases, Tenth Revision code of F84.0, F84.3, F84.5, F84.8, or F84.9
Breaking down the new numbers
The CDC found that the prevalence of autism in children is now 1 in 31. That’s 4.8 times higher today than in the first CDC/ADDM survey two decades ago. Then, it was 1 in 150 children. Here are additional findings from the latest survey:
- The increase isn’t because higher functioning children were included in the survey.
On the contrary, the percentage of ASD cases with higher IQs (> 85) has decreased steadily over the last six ADDM reports to 36.1% in the 2022 survey. Nearly two thirds of children with ASD in the latest survey had either severe or borderline intellectual disability (ID).
- Prevalence of autism varied by ADDM Network sites.
The lowest prevalence was in Laredo, Texas at 9.7 in 1,000 children. The highest prevalence was in California at 53.1 in 1,000.
- Autism continues to be more prevalent in boys than girls.
Autism was 3.4 times more prevalent among boys than girls. In California, prevalence of autism among boys was a staggering 1 in 12.5.
- Minorities continue to be more severely affected by autism.
Autism prevalence was highest among Asian/Pacific Islander children. Black, Asian, and Hispanic children – 78.9%, 66.5%, and 63.9%, respectively – had either severe or borderline intellectual disability.
- Children are being diagnosed on average at 4 years of age.
The median age of the earliest known autism diagnosis among children in the survey was 47 months and ranged from 36 months in California to 69.5 months in Texas.
Regarding the last bullet, the 4-year-olds in the survey had more evaluations and identification when aged 0-4 than the 8-year-olds in the survey. This is positive news because the earlier the diagnosis, the earlier children can receive beneficial treatment.
Children can reliably be diagnosed around the age of two (even earlier in certain cases). An earlier diagnosis at the age of two versus the age of four means children can benefit from two additional years of life-changing early intervention like ABA therapy, when their brains are most receptive to learning between the ages of 0-5.

What parents can do
We don’t know what causes autism. According to the HHS Secretary, research is underway on the origins of the autism epidemic and results are expected to start coming in this September. Hopefully, families can one day exercise preventative measures. Until that day, our focus and attention should be on early diagnosis and treatment. For parents, that means becoming an expert on your child.
- Monitor and keep track of your child’s development. They should be meeting specific developmental milestones as young as two months old. Use the CDC’s handy milestone checklists to help you keep track.
- Make sure your child’s doctor screens for autism at 18 and 24 months of age during well-child visits. Doctors should use a validated screening tool that can identify whether or not a child is learning basic skills and help determine if there might be a delay.
- Don’t wait to get a comprehensive evaluation from an autism specialist. If you and your doctor suspect autism, get your child evaluated as soon as possible by a qualified professional, such as a developmental pediatrician or child psychologist who specializes in autism. With a comprehensive evaluation, a diagnosis can be finally be made. And in the case of a positive diagnosis for autism, you can start early intervention – like the gold standard ABA therapy – as soon as you find an accredited provider.
