Approximately one in every 150 children in the United States has autism or a closely related disorder -- a figure higher than most recent estimates -- according to a federal survey released yesterday, the most thorough ever conducted.
Or maybe it isn't:
The new data, from 14 states, do not mean that autism is on the rise, because the criteria and definitions used were not the same as those used in the past.
That's because they aren't just counting "autism" but "related disorders" that may cause "some social disability." posted by Sydney on

I think it's a positive step that the data is being compiled in a more comprehensive manner pending the rewriting of DSM IV though. BEst wishes
Dear Sydney, It seems that something is on the rise. I agree that changing the definition of autism in 1980 has led to much confusion. You are probably too busy to read all this, but I have been working in the area of researching the existing research on paternal age. Because of the change in average paternal age since 1980 an upswing in the number of people with disorders such as autism and schizophrenia, diabetes 1 etc. would be expected.
I'm going to list a lot of sources and I certainly don't expect you to read them, but you might find the subject interesting when you have some time. Thank you very much. http://www.sciencedaily.com/releases/2002/10/021018080014.htm
