Rates of Autism Climb to New Highs in the U.S., With California Setting Record Numbers

New federal studies coauthored by autism experts at Rutgers found that more children have been diagnosed with autism than at any time since monitoring began more than two decades ago.

According to the U.S. Centers for Disease Control and Prevention (CDC), about 4 percent of 8-year-old boys and 1 percent of 8-year-old girls, have autism in the U.S. These estimates are the highest since the CDC’s Autism and Developmental Disabilities Monitoring (ADDM) Network was created in 2000.
