Appalachian stereotypes aside, this is not a cause-and-effect connection. It's a question of who decides to have additional children. If you have one autistic child, you most likely don't have any more children, because you are financially and emotionally bankrupt. But if you have the second one before you know about the first one, then you've got a second child who is far more likely than average to be autistic. The hypothetical second autistic child who would be born 3 years after their older autistic sibling, and thus balance out the statistics, simply never gets born.
