The Atlantic journalist talked to Stanford Professor Paul Graham Fisher who was co-chair of the university’s disability task force, so I imagine they either got it from him or someone else at the school.

They could have made it up, but since the article is a couple days old and no one has printed any retraction or correction, I'm more inclined to believe the number is accurate.

The number isn’t sourced. But the article does say 24% were receiving academic OR housing accommodation. So 38% registered disabled but only 24% receiving any type of accommodations sounds suspiciously like bullshit. It would require people registering and not using the thing they registered for. But most importantly OR. Where is the data on how many people are using academic accommodations ? Complaining that people at a 90k a year school receive a housing accommodation is just frankly absurd
