Commentary: Autism Rates Reach a Record High: One in 31 Children in the U.S. Has Autism

A new CDC report shows that autism diagnoses among U.S. children have reached a record high—1 in 31 eight-year-olds based on an analysis of medical records from 2022, up from 1 in 36 just two years earlier. At May Institute and the National Autism Center, we view this as an important reminder to continue to expand access to early identification, individualized intervention, and lifelong support for autistic individuals, including those with profound autism.

The CDC attributes the rising rates in part to improved awareness, better screening tools, and expanded access to diagnostic services, especially in communities that have historically faced barriers to care. This is reflected in the data: for the first time, Black, Hispanic, and Asian/Pacific Islander children are being identified with autism at higher rates than white children. Diagnoses among girls are also increasing. These shifts suggest that efforts to reduce disparities in diagnosis are working. Even so, more must be done to ensure equity in treatment and long-term supports.

More children are being diagnosed at younger ages, which is key for accessing early intervention services known to improve developmental outcomes. However, diagnosis is only the beginning—especially for profoundly autistic children and adults, who require intensive support and lifelong services.

This report underscores the growing demand for comprehensive services and the importance of research, resources, and policies that ensure all autistic individuals can live meaningful, fulfilling lives—regardless of their age, identity, or level of need.
