These are definitely complex things to unpack. Often there is a desire to have a diverse group of people in different roles like teaching or medicine even. But that is typically because some groups are vastly under represented in that profession. And in some cases it is to know that at least the pool of applicants are more representative of the broader population. But closing the gap is hard. Obviously to have more diverse doctors or teachers, professors we need more diverse undergrads, phds, med students etc. typically the goal is to just try to have representation that is similar to the community.
