One in 68 U.S. children has an autism spectrum disorder (ASD), a 30% increase from 1 in 88 two years ago, according to a new report released Thursday by the Centers for Disease Control and Prevention.
This newest estimate is based on the CDC’s evaluation of health and educational records of all 8-year-old children in 11 states: Alabama, Wisconsin, Colorado, Missouri, Georgia, Arkansas, Arizona, Maryland, North Carolina, Utah and New Jersey.
The incidence of autism ranged from a low of 1 in 175 children in Alabama to a high of 1 in 45 in New Jersey, according to the CDC.
Children with autism continue to be overwhelmingly male. According to the new report, the CDC estimates 1 in 42 boys have autism, 4.5 times as many as girls (1 in 189).
