“Autism spectrum disorder (ASD) is a developmental disorder. Someone with ASD may have difficulty with social interaction, communication, and behavior. For example, the earliest signs of ASD are that children may not make eye contact with their parents and may not be aware when someone is talking to them. About 30% of people (about 1 in 3) with ASD have an intellectual disability.”

“Statistics by CDC:

• About 1 in 36 children has been identified with autism spectrum disorder (ASD) according to estimates from CDC’s Autism and Developmental Disabilities Monitoring (ADDM) Network.
• ASD is reported to occur in all racial, ethnic, and socioeconomic groups.
• ASD is nearly 4 times more common among boys than among girls.”
