Most-cited autism numbers for fast journalist sourcing
Prevalence
- 1 in 31 U.S. children are autistic (CDC ADDM Network, 2022 data, released 2025) — up from 1 in 36 in the prior survey
- 1 in 20 boys are autistic; 1 in 64 girls are autistic (CDC ADDM 2022 data) — gendered diagnostic bias continues but the ratio is narrowing
- Prevalence has increased over time primarily because of expanded diagnostic criteria, better recognition of autism in girls and women, and reduced stigma around seeking diagnosis
Diagnosis
- Average age of autism diagnosis in girls/women: 72 years for those who get diagnosed at all
- The diagnostic criteria were developed studying 8-year-old boys; many girls and women, gender-diverse autistic people, and adults who learned to mask are undiagnosed
- The late-diagnosed adult population is the fastest-growing diagnostic category in the autism population
Employment
- 80% of autistic adults in the United States are unemployed or significantly underemployed
- The employment gap is primarily structural (workplace design) rather than capability-based
Co-occurring conditions
- 30-80% of autistic individuals also have ADHD (estimates vary by study population)
- Significantly elevated rates of anxiety disorders, depression, EDS/hypermobility, POTS, GI conditions, and sleep disorders
- 50-80% of autistic children have clinically significant sleep difficulties
Healthcare access
- Autistic adults have significantly elevated rates of avoiding healthcare due to system inaccessibility
- Mortality outcomes are worse than non-autistic peers, often due to delayed care and undiagnosed co-occurring conditions
Nevada-specific (Las Vegas project context)
- April 2026 FOX5 Las Vegas reporting documented Nevada autism families paying $80+ per hour out of pocket for therapy that state-mandated insurance coverage was supposed to provide
- The only direct comparable family destination in the Clark County metropolitan area closed in March 2026, leaving an unmet need across roughly 500,000+ residents
Police encounters
- Autistic individuals are at significantly elevated risk in police encounters compared to non-autistic peers
- Communication patterns common in autism (reduced eye contact, slower verbal processing, atypical responses to commands) can be misinterpreted as suspicious or noncompliant by officers without autism-specific training
