You are talking about proportional representation. Correct me if I am wrong.
If 12% of the population is black, you would like at least 12% of the workforce to be black. If 12% of the population is black you would like at least 12% of congress to be black. That sort of thing.
If that is correct, I suggest going back to what I already wrote and perhaps look up “equality of outcome”.
If it’s not correct you are really going to have to tell me what it is you are trying to say.
