From the link in the OP:

Most researchers say that there is a rise in the number of children who are landing somewhere on the autism spectrum and that only some portion of that increase can be explained by raised awareness of the disorder. In this decade alone, Insel says, diagnoses of autism spectrum disorder (which includes mild cases) have jumped to 1 in 110, from 1 in 150; in boys, it’s now 1 in 70. He worries that the rate is accelerating. “I would say I am losing sleep over this,” Insel says.
