Autism Diagnoses in the U.S. Rise 175% Over the Past Decade

A new study highlights significant increases in autism diagnoses, especially among young adults and females, pointing to evolving screening practices and awareness.

The study analyzed data from 12.2 million Americans, revealing a jump in autism cases from 2.3 to 6.3 per 1,000 people between 2011 and 2022.
Young adults aged 26 to 34 saw the most dramatic rise in diagnoses with a 450% increase during the study period.
The gender gap in autism diagnoses is narrowing, with a 305% increase in diagnoses for girls and a 315% rise for adult women.
Researchers attribute the rise to improved screening, changes in diagnostic criteria, and increased awareness and advocacy.
Despite the increase, experts suggest current figures may still underestimate the true prevalence, particularly among older adults and females.
