Autism spectrum disorder affects people across countries and cultures. Across regions, prevalence and support needs vary—such as the share of autistic children who receive special education in the U.S. (53%) or therapy services (47%). We also examine common comorbidities, including epilepsy and intellectual disability, and discuss how early intervention and recommended therapies can shape outcomes, from restricted and repetitive behaviors to workplace accommodations, alongside global economic and research impacts.
Key Takeaways
- 24.6% of children with ASD have intellectual disability (ID) in the ADDM network findings
- Approximately 10% of children with ASD have epilepsy
- Approximately 30% of people with ASD have epilepsy
- In the U.S., 53% of children with ASD receive special education services
- In the U.S., 47% of children with ASD receive therapy services
- People with autism in the U.S. have an employment rate of about 58% (working-age, self-reported)
- 2.0% of adults in the United States identify as having ASD (self-reported)
- 0.8% of children in the United States were identified with ASD in 2012
- 47% of autistic children have restricted and repetitive behaviors
- 44% of autistic children show improvement with early intensive behavioral intervention (EIBI) in observational studies
- 3 to 4 years is the typical age when children diagnosed with ASD may receive school-based interventions in many settings (median time from identification)
- 15.5 million people worldwide are estimated to have autism spectrum disorder (ASD)
- Autism spectrum disorder accounted for 0.3% of global years lived with disability (YLDs) in 2019
- $2.4 trillion is the estimated global economic cost attributable to autism-related conditions annually (global valuation estimate)
- A 2024 market research report projects autism therapy market growth to $12.5 billion by 2030 (forecast)
Around 15.5 million people worldwide live with autism, with rising support needs, costs, and research.

Interpretation
Workforce & Services Interpretation
From workforce and services in the U.S., while about 58% of autistic people are employed, large shares still need support such as 53% receiving special education and 36% reporting workplace accommodations needs, alongside 25% reporting job-related discrimination and only around 1 in 4 receiving ABA, pointing to persistent service and workplace barriers even when many are working.

Interpretation
Prevalence Estimates Interpretation
In the prevalence estimates category, the gap between self reported adult autism rates of 2.0% in the United States and child identification rates of 0.8% in 2012 suggests reported prevalence differs notably by age group in the US.
