Hi autistic here. One thing to keep in mind is that autism prevalence appears to be increasing because testing has gotten better : was 0.04% when I was a kid 30 years ago, now 2.78%. Also Asperger's was merged into ASD in 2013. Keep this in mind when reading sources like this.

Testing did not get better ... please check the design of the tests and keep in mind that most of these tests happen in/under "lab conditions".

Sorry it got 69 times better or 6800% better. https://www.cdc.gov/ncbddd/autism/data.html.

But doesn’t more awareness lead to more testing which results in more cases being found due to a larger population being tested?
