US universities also had a history of trying to exclude Jewish people [1]. I say history, because the practice has by all accounts stopped, and the current situation in the Ivy League [2] is as follows (looking only at non-international students):

                          Ivy League   US      Ratio
  Jewish                  17.2%         2.4%    7.16
  Asian                   19.6%         5.3%    3.71
  White (incl. Jewish)    50.3%        61.5%    0.82
  Hispanic                11.4%        17.6%    0.65
  Black                    7.8%        12.7%    0.61
  White (non-Jewish)      33.1%        59.1%    0.56

The numbers don't sum to 100% because I did not include multi-ethnic students, a few minor ethnicities (American-Indian, Pacific Islander..), and students categorized as "unknown" or "other" by the universities. Data on university undergraduate demographics was taken from the universities own diversity reports. Jewish representation was was gathered from http://hillel.org/college-guide/list/, https://forward.com/jewish-college-guide/, and https://ejewishphilanthropy.com/how-many-jewish-undergraduat..., taking the lowest estimate when sources conflicted. ejewishphilanthropy.com (eJP) points out flaws in Hillel's data gathering (e.g. showing Harvard as 30% Jewish, when eJP found it only 16%) Hillel seems to have since fixed these flaws, as the estimates they now give are in-line with those of eJP.

No correction has been made to look at only the college-age population of the US, or only at the Northeastern US where all the Ivy League universities are located, so that may be a source of some bias.
