Autism Identification Improves in U.S., Especially Among Black, Hispanic, and Female Children

Autism identification continues to improve in the United States, particularly among groups historically underdiagnosed, according to new CDC data released in May 2025. The report shows autism prevalence among 8-year-olds rose to 1 in 31 (3.2%) in 2022, up from 1 in 36 (2.8%) in 2020.

Better Detection in Minority Groups

The increase stems primarily from improved screening and diagnosis in Black, Hispanic, and female children — groups that have faced systemic barriers to identification. The male-to-female ratio narrowed from 4.2:1 to 3.8:1, suggesting clinicians are getting better at recognizing autism in girls, whose traits may present differently.

The report shows autism prevalence among 8-year-olds rose to 1 in 31 (3.2%) in 2022, up from 1 in 36 (2.8%) in 2020.

'These data show our screening tools and awareness are finally starting to catch up with the full diversity of the autism spectrum,' said a Johns Hopkins researcher analyzing the findings.

Geographic Disparities Persist

Prevalence varied widely by state, from 1 in 19 children in California to 1 in 103 in Texas — differences attributed to uneven access to diagnostic services rather than true incidence variation. The CDC's Autism and Developmental Disabilities Monitoring Network tracks these figures across 16 communities.

What's Behind the Rise?

The steady increase in autism prevalence — from 1 in 150 children in 2000 to today's 1 in 31 — reflects broader diagnostic criteria, reduced stigma, and improved screening in schools and pediatric offices. As CNN reported, no evidence suggests an environmental 'epidemic.' Decades of research have debunked links to vaccines or acetaminophen use during pregnancy.

'The numbers tell us more about our diagnostic systems than about autism itself,' noted a CDC epidemiologist. The National Institute of Mental Health emphasizes that autism is a neurodevelopmental variation present from birth.
