Two years ago, two schools were above 50% in international student enrollment; last year there were none. In 2018, one school, Purdue University's Krannert School of Management, eclipsed the 50% threshold, but because of program downsizing stayed about the same in actual numbers of foreign students enrolled. Meanwhile, 36 of the top 50 schools have recorded losses since 2016, and 32 of 50 since 2017.
