I checked Autism rates in some countries (of course it's impossible to even get a close estimate without some mandatory census of the entire population).
I would expect rates to be higher in the USA compared to Denmark, but no. The USA with more pollution, artificial food flavorings, unhealthy food, smoking, and chemicals. Two possibilities come to mind, the estimation is flawed or the genetic homogeneity of Denmark offsets the benefits their healthier lifestyles in the risk of getting autism.
I suppose a lot of our genetic diseases missing from animals come from our inbred nature. Humans are very very homogeneous.
Edit: One thing this estimate didn't do is note how severe the autism is.
Has autism increased? Maybe not.
Has the severity been going up? Possibly, and it could be a different type of epidemic I would be worried about. The numbers aren't increasing but the symptoms are getting more and more severe. (Just a hypothesis)
Is the autism in Denmark more likely to be less severe than in a pollutant/artificial flavoring/ melting pot like the USA, China, or India? I want to see if anyone knows. Americans use far more of certain types of medication than many other first world countries. But does Denmark have higher amounts of people using a certain type of drug as well?
Thats what I would expect you to find: Denmark having a higher rate than the USA. Basically they probably have the same actual rate of actual autism, but more autism gets missed by the medical authorities in the US than in Denmark. Denmarks is smaller (physically, and in population), is more homgeneous, and has socialized medicine, and so forth. America is bigger and has more minorities, and things are more likely to get missed here.
