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"
It’s not meant to be spoken, it’s supposed to be a writing standard as opposed to a spoken one.
“E” is also pretty common and it seems to be used interchangeably with “X”. That’s probably more of a personal choice.
“X” is also commonly marketed as “Yankee solution finding”, when it was first proposed by a Puerto Rican Psychologist to challenge the gender binary of Spanish. It is not an American invention, it just gained popularity there first.
