@nrtlax33 If there is in fact a nefarious reason for the estimate, Chicago (or any other school) can easily fudge the reported “official” numbers regarding enrollment and we would have no way of knowing it. Besides, you don’t seem to believe those official numbers, either, so I am not sure how you would be convinced. It is also true that a lot of other schools do not provide enrollment numbers from term to term as Chicago does, a point already brought up by @HydeSnark . If they were trying to hide something, wouldn’t you expect them to provide less detail, not more?
