It seems Jewish life is already thriving on campus - despite being just ~2% of US population, they are 7/11% of Stanford's undergraduate/graduate students [1]. To put that into perspective, and excluding from analysis the 10% international students, they are 3.9x over-represented among non-international undergraduates, relative to their US population.
In contrast, white (including Jewish) undergraduates are only 32.6% of undergraduates, but 57.8% of US population [3]. Meaning non-Jewish whites are 25.6% of undergraduates, making them 0.49x under-represented.
So despite a Jewish person having a 7.9x greater chance of getting into Stanford than a non-Jewish white, Stanford's president is apologizing that this disparity isn't even greater.
