Now its gonna get interesting. This could lead down a path where the answers will vary widely. We might get down to the Why. And this will illustrate some very different views.

There were no applicants of other ethnic groups for Science positions. None. Zero. In fact, sitting in on interviews with applicants for science positions for about 12 years now, the vast majority of these applicants are clearly white and male. Females on the rise however.
I have seen zero black applicants. I have never been on a faculty with a black science teacher. The approximate racial breadown of the students in these schools would be 40% Hispanic, 40% White, 20% Black. The school I teach at presently (a burb school) would go about 55% White, 35% Hispanic, 10% Black. The Schools I have taught at average about 3000 students. The current school well over 3000 students.

Interesting pattern. In fact in all my upper division and graduate level science courses (these were small classes at a very large institution, University of Texas) there were zero black students... I get the Newsletter from the school of Natural Sciences at UT. They give you an update on the diff. graduate students and professors and what they are researching. Zero black students. Zero black professors. More females than my day. My GUESS is there are no black applicants for faculity or graduate students.

Why the obvious discrepancy in numbers? Black people hate science?
