Your own copy-and-paste proves my point, in a couple of different ways.
First, it specifies that the census form separated race from ethnicity. My point in my previous reply to you was that you were mixing up ethnicity with race. The Wiki article further demonstrates that the two are separate, and further, that Hispanics are not a race.
Second, it states, in the first sentence, "Many Americans who are treated as part of minority groups ..." (Emphasis mine) They are treated as minorities, as Brother Ignatius said, because of political reasons.
So-called minorities can be either ethnicities or races. Members of the Black race are considered a minority, and so are Hispanics of every background.
Third, you ask if the census board wouldn't need to allocate a category for "Native Americans," and present the supposed lack of such a category as proof in a question. The answer is that you need to read more carefully and more critically. There isn't an anthropologist on Earth, or even anyone with common sense that would agree that "Asian American" is a race, yet the census board divided race into categories that include "Asian American." From that, you should be able to conclude that the census board's categories are political, and should not be used as an authoritative source for determining what race a given ethnicity belongs to. |
