The incidence of autism spectrum disorder among US children has increased by roughly 30% in recent years, according to the Centers for Disease Control and Prevention’s (CDC) latest analysis.
The data are from the CDC’s Autism and Developmental Disabilities Monitoring Network (ADDM), which has carried out surveillance programs in 14 states beginning in 2000. The programs have calculated incidence rates among 8-year-old children because it appears to be the age at which prevalence peaks.
