The U.S. Centers for Disease Control and Prevention estimates that 1 in 88 children in the United States has been identified as having an autism spectrum disorder (ASD), according to a new study released March 29 that looked at data from 14 communities. Autism spectrum disorders are almost five times more common among boys than girls — with 1 in 54 boys identified.
The number of children identified with ASDs ranged from 1 in 210 children in Alabama to 1 in 47 children in Utah. The largest increases were among Hispanic and black children.
The report, Prevalence of Autism Spectrum Disorders — Autism and Developmental Disabilities Monitoring Network, 14 Sites, United States, 2008, provides autism prevalence estimates from 14 areas. It was just published in the Morbidity and Mortality Weekly Report.
