1 in 31 U.S. Children Are Autistic, CDC Reports, with Improved Identification Among Minority Groups

The proportion of autistic children in the U.S. has risen to 1 in 31, according to the latest data from the Centers for Disease Control and Prevention (CDC). The CDC's Autism and Developmental Disabilities Monitoring (ADDM) Network reported in May 2025 that 3.2% of 8-year-olds were identified as autistic in 2022, up from 2.8% in 2020. This marks the continuation of a 15-year trend of increasing recognition, driven largely by broader diagnostic criteria and improved awareness.

Improved Recognition Across Demographics

One of the most notable findings in the CDC's report is the narrowing gap in autism identification among racial and ethnic minority groups. Historically, Black and Hispanic children were identified later or less frequently than white children due to systemic barriers like medical racism and diagnostic bias, but the new data suggests progress in addressing these disparities. For example, the proportion of autistic Black children increased by 12% since 2020, while Hispanic children saw a 9% rise. These shifts likely reflect improved access to screening and diagnostic services in underserved communities, though advocates caution that over-policing of Black autistic children remains a concern.

What’s Driving the Increase?

Experts emphasize that the rise in autism recognition is primarily due to broader diagnostic criteria, increased awareness, and better screening tools. As Johns Hopkins Bloomberg School of Public Health noted, the trend aligns with decades of data showing steady increases as diagnostic practices evolve. The CDC’s ADDM Network, which tracks autism prevalence across 16 U.S. sites, relies on health and education records to identify cases, though this methodology may miss undiagnosed individuals.

Community Response

The Autistic Self Advocacy Network noted that while improved identification can help connect more people to needed supports, it's crucial to ensure services focus on acceptance and accommodations rather than compliance-based interventions. The Autism Society of America also welcomed the report but highlighted the need for continued investment in culturally competent services.

Addressing Misinformation

While the CDC’s findings are grounded in peer-reviewed research, some have misrepresented the data to promote debunked theories. These claims, as FactCheck.org reported, lack scientific basis. The CDC’s report does not suggest any environmental or medical cause for the rise in recognition, focusing instead on detection factors.
