In software development, in the mainland US, my experience is that Oriental and Indian women are disproportionately over-represented, and black women are almost non-existant statistically (I've known of a grand total of 1 black female programmer in 25+ years, for example.) Some white women, but a disproportionate number of them are Russian or Eastern European immigrants rather than natural born citizens.
The term "underrepresented minority" is misleading.
In any state where nonhispanic whites are a minority (e.g., CA), they are typically an underrepresented minority (only Asians tend to be truly overrepresented). I've never heard whites described as "minority" as a result of this.
Non-hispanic Whites are not a minority in California [1]. And even if they were, I'd be very interested in seeing any statistics that show them as underrepresented in any context of significance (i.e. not prison).
Though I still think the statement, "any state where nonhispanic whites are a minority (e.g., CA), they are typically an underrepresented minority" is very much hyperbole, which was the point I was trying to make.
