As part of the enrollment paperwork that we do w/ new students at the career school I work at, students are asked, (they can decline), to select the racial category that they identify with.
The 1st question is" Do you consider yourself Hispanic/Latino?"
The 2nd part of the question is:
In addition, select one of more racial categories to describe yourself:
American Indian or Alaska Native
Asian
Black or African American
Native Hawaiian or Pacific Islander
White
It's about 60/40. Some don't select and other category and the rest in fact, select White. The ones that are darker than me, usually.

I don't care, I just find it..interesting.
Strangely, the ones that are Black/Mexican mixed, rarely claim their Mexcian side.
