Turns out if you define a third of your pale population as "Latinx" instead of white, very few white people remain.
Even the 2020 census had the sense (heh) to finally drop the "Hispanic race" and have it as a separate label, but the "researchers" felt like going out of their way to redefine it as a "race" again. Not sure why race is even treated as a scientific thing to begin with in their census, but such is the Amerikkkan way I guess.
Edit: don't even want to think about the causes of this "age gap"
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.
In my work I've had to fill out that kind of forms a couple of times for Latinos and some have this options "Cuban, Hispanic, Mexican, Puerto Rican". It makes total sense.
Do you mean they have those options as a response to the race question? Or as a question separate from race? Cuz if you mean the latter, then those are the same options given in this census
