In the US at least, there are likely three factors all combining for the increase in autism diagnoses:
1) The definition of autism was officially broadened to include a whole ‘spectrum’, whereas it was once a very limited and extreme diagnosis.
2) There is funding now for both schools and parents with kids given the diagnosis, which has encouraged parents of children with all kinds of developmental, behavioral and mental disorders to seek an autism diagnosis—and professionals to give one.
3) Some sort of environmental/exposure factor is also likely involved, as we know that the incidence of fairly severe autism has increased in certain regions and populations quite dramatically.
That #3 is still unclear, but I wonder have you seen and investigated the newly discovered potential link to antidepressants, as posted on this thread?
Right on the money. However, are you aware that the criteria to be found eligible for special education services will be changed in the next year or so? I'll bet dollars to donuts that the numbers of children on the spectrum will drop dramatically. It will be interesting to see who takes the credit.
