I have been looking at several graduate programs in astronomy/astrophysics and I've come across a few with track records of low enrollments according to AIP: http://www.aip.org/statistics/trends/archives/astrost10.pdf Statistics from previous years: http://www.aip.org/statistics/trends/archives/astrorost.htm Case Western, Ohio State and Rice University for example have had 0 or 1 graduate enrollments several years in a row, even when according to gradschoolshopper (who get their data from AIP, though I don't know where), they admit many more students than the number that actually enroll. The one with 0 enrollments several years straight was Rice U. I'm guessing this can mean one or more of the following: -The data is wrong. -More students are admitted that can be actually fully funded by the department, hence admitted students turn them down when they get offers with no/low tuition remission and stipend. -Students simply took up better offers elsewhere, somewhere with palm trees. Is this a warning sign to stay away from these universities or is it some error in the report? I quite like the programs at cwru and Ohio, I thought they had a very good reputation.
