Autism rates by state
Nationally about six students in 1,000 are classified as autistic, but the rates vary widely by state. According to data reported by the U.S. Department of Education, the diagnosis is 10 times as prevalent in Minnesota as in Iowa. The map of autism rates for children ages 6-17 shows they are highest in the Northeast and on the West Coast and lowest among the Southern and Plains states.
