The noise on the walls is comforting to people on the autism spectrum, provided it’s bound by inferred structures. You have to also understand that elementary school education is almost universally female, much more so programming is male dominated. Like software, elementary school education is also a pool for adults on the autism spectrum substantially higher than general population average.
My wife is working in preschool and wanted to have some examples to discuss with her. I know plenty of those for overrepresentation of AuDHD spectrum in IT (especially males), but don't know any for schools. Especially since women are often not that obvious.
I don't have statistics. My wife works in elementary special education. Previously to her current assignment to a classroom with assigned students she worked across the entirely of a large school system as adviser.
