The rate of autism in a group of 8-year-olds in the US rose from 2.76 percent (1 in 36) in 2020 to 3.22 percent (1 in 31) in 2022, according to a study.
The slight increase in autism rate is attributed to improved access to evaluations in underserved groups, including Black, Hispanic, and low-income communities.
The data comes from the CDC-funded Autism and Developmental Disabilities Monitoring (ADDM) Network, which has been tracking the prevalence of autism spectrum disorder (ASD).
In 2020, for the first time, higher ASD rates were observed in underserved communities, and the link between ASD and socioeconomic status also diminished.
