Is the U.S. academy "overwhelmingly white"?

The Adida et al. 2020 PS: Political Science & Politics article "Broadening the PhD Pipeline: A Summer Research Program for HBCU Students" claimed that (p. 727):

The US academy today is overwhelmingly white, with only 8% to 9% of full-time science and engineering faculty as underrepresented minorities (DePass and Chubin 2008, 6).

This evidence to support the claim that the "US academy" is "overwhelmingly white" is the percentage of a *subset* of the U.S. academy (science and engineering) that is not White *and not Asian*, given that Asians were not considered underrepresented minorities in the calculation of the percentage. Moreover, the cited publication is more than a decade old, and the data might be even older than that.

Below is a plot of data from 2018, for the U.S. academy as a whole, of data from the National Center for Educational Statistics. The light areas indicate the percentage White for each rank and overall, compared to the total White, Black, Hispanic, Asian, Pacific Islander, and persons of two or more races; the percentage does not include persons with an unknown race/ethnicity and does not include non-resident aliens.

Overall, in Fall 2018, about 76% of U.S. full time faculty at U.S. degree-granting postsecondary institutions were White, which matches a calculation in this Pew study or Fall 2017. So, if you randomly selected four of these faculty, one of them would be expected to be non-White. I'm not sure whether that counts as being "overwhelmingly white".
