Fair enough. I formerly went through large schools' reported numbers, which isn't the most straightforward thing to find. UT Austin has 4,299 registered Spring of 2025, which is 12.9% of a 55k student population. Ohio has 5,724 of a total of 66,901, so 8%. FSU is ~5,000 of ~55,000: 10%. These are all much higher than the article's claim but definitely lower than the NCES survey.
This cites an NCES study which doesn't appears to be locked down to approved researchers, but it provides a national number:
> In 2019-20, 8% of students registered as having a disability with their institution. This rate was 10% at non-profit institutions, 7% at for-profit institutions, and 7% of students at public institutions.
The National Center for Education Statistics disagrees with 3-4%.
