Almost. I’m saying that the ratio should be close to the ratio of those who are qualified for the particular position in the hiring area for the company. If they are not getting the applicants, then some sort of outreach program is appropriate. If they are getting the applicants, but a particular class is underrepresented in their workforce, then hiring preferences should be used, in the following manner:
70% of our accountants are of class Z, 25% are class Y and 5% are class X. However, in the hiring area, and in our applicant pool, about 40% of the qualified accountants are of class Y, with about 55% class Z and 5% class X. We should therefore preferentially hire qualified applicants of class Y (all other qualifications being equal) for our open positions until we’re reasonably close to the same ratio as in the hiring area.
(I hope I said that right.)
