"Minority" is a code word for "Black/Hispanic". Asians don't count.
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.

Nonhispanic whites make up only 32% of UC Berkeley. That's underrepresented.

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.
