This is because in 2013 the *definition* of autism was expanded to include Asperger's, CDD, PDD-NOS, and the Autistic Disorder.
Numbers went up because the definition changed to include more variants. And testing and awareness of Autism just got better over time. This is insane.
In the last 22 years, autism rates among children have increased nearly 400%.
It's time to make our children healthy again!
