Businessweek's new ranking gives the best M7 diversity rank to Stanford which places 16th on the magazine's new diversity index of its MBA ranking. Even though Harvard ranks just below Stanford, however, HBS has enrolled a significantly higher percentage of Blacks and Hispanics. The bigger difference is in gender which is also accounted for in the diversity rank. Stanford is closer to gender parity with 47% women, while Harvard is at 44%, according to Businessweek's data. One other interesting insight: White students at Wharton are no longer a majority, making up 48% of the MBA enrollment.
