“They (Jews) make up a plurality of the white kids, normally.”
You mean the students of Ivy League colleges?
Interesting. Is it still true?
I don’t know if it is still true in the Ivys. Jews have fled them en masse.
It is true in the “New Ivys” (e.g., Vanderbilt, Rice).
They don’t track it directly, but you can back into it (roughly) because they’ll say “50% white, 40% Asian, 10% other” and then have a percentage of Jewish like “40% Jewish”.
You make the assumption that most Jewish kids are white (more or less true), and there you have it.
It was certainly my daughter’s experience. Basically all her white friends or acquaintances were Jewish.
