A report from the Centers from Disease Control and Prevention indicates that prevalence of autism spectrum disorder in the United States increased 15 percent from 2012 to 2014. The CDC has tracked autism rates at 11 U.S. sites since 2000, and the new numbers mark the highest autism spectrum disorder prevalence to date – 1 in 59 children at age 8.
The CDC collected data from sites in Arizona, Arkansas, Colorado, Georgia, Maryland, Minnesota, Missouri, New Jersey, North Carolina, Tennessee, and Wisconsin that are part of the Autism and Developmental Disabilities Monitoring (ADDM) Network.
Results of this report are consistent with previous research suggesting boys are four times more likely (1 in 38, 2.7 percent) than girls (1 in 152, 0.7 percent) to be diagnosed with autism. Researchers at the Johns Hopkins Bloomberg School of Public Health contributed to the CDC report.
