Racial categories have always been jank in the US for Latin people. Forms have a separate question on whether or not you're Hispanic. But because of that, "Latin" is never included as an option for race so we have to fill in something stupid.
Look at questions 8 and 9 here. I'm the tan kind of Mexican American, so I have to answer question 8 with Yes, Chicano and question 9 with...??? Other? I'm a Hispanic Other. Makes sense.
