From Anne Dachel of The Age of Autism.
In 2006 and in 2007, I wrote stories on "The Really Big Lie About Autism." This is of course the insane claim that the autism epidemic is simply the result of an expanded definition and greater awareness.
Back in 2006, the rate was one in every 166 children and in 2007, it became one in every 150 children. Regardless, whatever the rate, it's always because of the same thing: No real increase--greater recognition.
It's just been announced that we now have an autism rate of one in every 50 children, one in every 31 boys. The official disclaimer is unchanged, as seen in media reports.
