This is a really great question. I checked.

Turns out that the poorer a nation is, the less reported autism they have. That could be because there is no benefit to the diagnosis or it could be because they have less healthcare in general and a real diagnosis can easily take 4-8 hours of clinical time.

Interesting either way.

Or it could be because poorer countries actually have lower rates of autism. I'm not claiming that's the case, just that we don't have any reliable data on it one way or the other.
