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"
That'd be the correct way thinking in 1990 before they added "latino" as a synonym [PDF, page 3], but then they just randomly added that in without changing the question. Since Yankee ethnography is so crap and they usually don't even define their shit properly, as most social Yankee stuff (unrelated but they don't have a list of proscribed domestic terrorist groups, only foreign ones) you can never really know what strange conclusions their researchers might come to. It makes sense that they'd be terrible at this when the "Hispanic Question" is literally the only ethnicity question in the census, and you have shit like "race white, for example, German, Italian."
Yet; let the steady collapse of hegemony slide further and bet you'll start seeing more direct-action oriented enclaves getting flagged for terrorism. They did just clink up the Uhuru House for 'undeclared foreign agency'; and that's an adjacent bullshit charge.
