For instance, I'm sure that Africa has very low diagnosed rates of autism, but I don't think you could ever make the assumption that that is because there are actually lower rates of autism there. Ditto for chunks of Asia and probably most of South America.
I think that some well-designed, international population prevalence surveys (all using identical diagnostic criteria) would be an incredibly useful research resource.
It might help with questions about the supposed rise in autism, autism in countries with different exposure to various supposed risk factors and the claimed ethnic variations.
The biggest problem I see is how to develop some value to the countries and individuals who are surveyed. There seem to be enough problems defining the benefits of diagnosis, and creating services / therapies / actions that provide value to people diagnosed in wealthier, developed countries.
