What is Autism Spectrum Disorder?

Autism Spectrum Disorder (ASD) refers to a complex, neurodevelopmental disorder with a broad range of patterns of behavior and difficulties with social communication and interaction. The term “spectrum” refers to the wide range of symptoms, skills, and levels of disability in functioning that can occur in individuals with autism.

How many people with Autism Spectrum Disorder live in Pennsylvania?

Pennsylvania is among the only states with an administrative census initiative that counts individuals who are the spectrum receiving services from multiple systems. Using data from 2011, the Pennsylvania Autism Census Project found more than 55,000 individuals on the spectrum across the state. When we apply the prevalence of autism spectrum disorder established by the CDC Autism and Developmental Disability Monitoring Network (ADDM) in 2010, there may be more than 185,000 people on the spectrum in Pennsylvania.
