I kind of thought that the fact I provided a number at all implied that it referred to the diagnosed, but the point that we can't know what we don't know is fair.
Still, my point stands. Most people who have it badly enough to get diagnosed can't hold jobs. Autism isn't some quirky personality trait that makes you a special cool kid on Tik-tok. It's a government recognized disability.
I'm dx'd level 2 and have a job. I think your stats are out of date. Yes, unemployment is high in the autistic community. But it's not to the degree you suggest.
