Autism: CDC Releases New Autism Prevalence Data

On April 12, the Centers for Disease Control and Prevention (CDC) released its Morbidity and Mortality Weekly Report (MMWR) which included a study of data from 2010, 2012, and 2014 on the prevalence of autism among four-year-old children across study sites in seven states. The data indicate that the prevalence rate was 1 in 59. However, prevalence rates varied greatly between study sites. Of the three states that had data for all three years, only one (New Jersey) had an increase, while the rates in the other two (Missouri and Arizona) remained stable. These three sites also reported no improvement in age at first evaluation. These study sites were part of the Early Autism and Developmental Disabilities Monitoring (ADDM), a subset of the broader ADDM, which primarily monitors autism prevalence among eight-year-old children.
