Additionally, the report found that about one-third of the children identified with ASD who had IQ scores also had an intellectual disability of some kind. Key findings from the report include the fact that males were more than four times as likely to be diagnosed with ASD than females. That report estimated the prevalence of autism to be 1 in every 54 8-year-olds or 18.Īs the CDC explained, the ADDM network collected data on 8-year-olds because previous research showed that most children with ASD had been identified for services by that age. The Centers for Disease Control and Prevention issued its Autism and Developmental Disabilities Monitoring (ADDM) Network report in 2020, covering data for 2016. It is called a “spectrum disorder” because its characteristics and range of symptoms occur along a continuum.
Autism spectrum disorder (ASD) is a lifelong neurological and developmental disorder that typically begins during the early stages of childhood.
