Autism affects an estimated 15.5 million people worldwide, yet the picture looks wildly different depending on where you live and how care is measured. In the U.S., 0.8% of children were identified with ASD in 2012 while 2.0% of adults self report autism, and only about half of children with ASD receive special education or therapy support. This post brings those gaps into focus alongside health, education, and cost figures that change what “support” means on the ground.
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)
Autism affects about 15.5 million people worldwide, with frequent co occurring health needs and rising support efforts.

How We Rate Confidence
Models
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
Single source
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
Directional
Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.
AI consensus: 2–3 of 4 models broadly agree
Verified
All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
AI consensus: 4 of 4 models fully agree
