Trump misleads about autism statistics
Trump said “not long ago, and you can't even believe these numbers, one in 10,000 children had autism, one in 10,000 and now it's one in 36.”
He is correct about the current rate being one in 36, per the U.S. Centers for Disease Control and Prevention.
It’s not clear what year Trump was referencing for his “one in 10,000” statement, but in 2000 it was one in 150, according to the CDC.
There are reasonable explanations for why the rate is higher now than decades ago. The autism criteria shifted in 2013 when three diagnoses — autistic disorder; Asperger's syndrome; and pervasive developmental disorder, not otherwise specified — were merged into a singular autism spectrum disorder diagnosis, Evan H. Dart, University of South Florida associate professor in the school psychology program, previously told PolitiFact.
"This alone could explain large increases in medical diagnoses of autism since the 2000s, even more so compared to the 1980s," when autism first appeared in the Diagnostic and Statistical Manual of Mental Disorders, Dart said.
