Information that policymakers, educators and service providers can use
How can policymakers, educators and service providers plan now to meet current and future needs of people with autism and other developmental disabilities?
We have collected information and resources to help high-level planners understand the prevalence of autism, facts about autism insurance mandates, and agencies that serve people with disabilities.
What is the prevalence of autism spectrum disorder?
The CDC funds the Autism and Developmental Disabilities Monitoring Network (ADDM), whose most recent report, in April 2025 based on 2022 data from 16 states and US territories, found an overall prevalence of 1 in 31 8-year-old children with ASD (3.2 percent). In 2022, the rate of ASD for 8-year-old boys was 3.4 times higher than among girls at all sites. Additionally, the same ADDM sites contributed to prevalence numbers among 4-year-olds, finding a prevalence of 1 in 34 children (2.9 percent). Research sites in 16 states and US territories participated, including Maryland. Other sites were in Arizona, Arkansas, California, Georgia, Indiana, Minnesota, Missouri, New Jersey, Pennsylvania, Puerto Rico, Tennessee, Texas (Austin and Laredo), Utah, and Wisconsin.

What are autism insurance mandates?
Starting in the early 2000s, states began legislating that heath insurers cover certain therapies for children diagnosed with ASD. The policies vary by state, such as what ages are covered, what therapies are covered, and coverage maximums per child.
