I was recently advised by a friendly moderator that when I want to create a tag, I should not just go ahead and create it. Rather, I should bring it up at Meta.
However, there was a question about a "diversity" tag already, and there someone said, Just create it on the fly when the need arises. Which is what I did, since I think this one is a slam dunk. More and more universities are working hard to recruit if not diverse faculty members, at least culturally competent candidates.
This seems like a useful tag. It isn't already covered well by any existing tags (there is just a little bit of overlap with gender), and it can be applied to some existing questions on this site. For example:
I have created the following tag wiki excerpt for this tag, to clarify when it should be applied:
On the diversity of academic disciplines, institutions, or events, including ethnic, gender, socioeconomic, geographical, or other kinds of diversity. Includes questions about diversity statements, increasing diversity of participants in an event, lack of diversity, and others.
