Neurodiversity is no longer a side note in health and education data, with 2025 studies placing neurodevelopmental differences in about 1 in 5 people. Yet the numbers don’t match how schools, workplaces, and healthcare systems respond, creating a sharp gap between prevalence and support. Let’s look at the statistics closely and see where expectations are lining up and where they are falling behind.
Key Takeaways
- Average age of autism diagnosis is 4 years 6 months in US.
- 65% of neurodivergent students drop out of higher ed.
- 85% unemployment rate among autistic adults without college degree.
- 55% of autistic adults have anxiety disorders.
- Approximately 15-20% of the world's population are neurodivergent, including conditions like autism, ADHD, dyslexia, and dyspraxia.
Neurodiversity is common, and recognizing it helps create more inclusive workplaces and schools.
