Indians make NM most diverse state except Hawaii.
The standard seems to be the state with the highest percentage of minorities. Something like 60% of New Mexicans are non-whites. Oklahoma undoubtedly has a higher percentage of Indians, but it's still more than 50% white.
The key difference is that New Mexico is 46.3% Hispanic. That outweighs Oklahoma's large Indian population and makes New Mexico more diverse.
As far as I know, there are only four race categories, so how are they slicing what they consider to be diverse races, total numbers of non-whites? By the way, Hispanic is still considered Caucasian and not black, yellow or red.
Also, I meant immigrants to Oklahoma, not from the eastern hemisphere.
If we're talking about cultural diversity, locations such as metropolitan New York or New Jersey probably have people from thousands of cultures around the world. Even in Native terms, Alaska has more than 250 tribes and villages, and California has 109 tribes and rancherias. Even if you group tribes with related cultures, I think either state would far out-diversify Oklahoma culturally.
In racial terms, New Mexico has large numbers of whites, Hispanics, and Indians and smaller numbers of blacks and Asians. Oklahoma has large numbers of whites and Indians and smaller numbers of everything else. New Mexico "wins" because of its Hispanics.
Rob's facts are in question?
The article refers to "racial/ethnic minorities," so I think it's covered its bases regarding Latinos. Latinos may belong to any race: white, Indian, black, or other. They aren't all Caucasians by any means. But whatever they are, I believe the Census tracks them as a separate ethnic group.
You can read about it here:
Race and ethnicity in the United States Census
but I think it's standard practice to treat Hispanics and non-Hispanic whites as two racial/ethnic groups, not one. I suspect every Census article will do what this one has done: break down the population into non-Hispanic whites, Hispanics, non-Hispanic blacks, and so forth. And keep them separate when discussing America's minorities.
Let's note that Latinos come from seven countries in Central America, 15 in South America, 13 in the Caribbean, and Puerto Rico. A state such as New Mexico with a large Latino population is ethnically and culturally diverse. Especially since Latinos are a complex blend of European, African, and indigenous strands, as I said. Add to that the 24 Indian tribes located in New Mexico and you have an incredible amount of both kinds of diversity.
You're welcome to defend Oklahoma all you want, but you really haven't addressed my points. Any state where the majority belongs to a single racial or ethnic group isn't racially diverse by definition. If the number of Indian tribes defines racial or cultural diversity, Alaska and California are much more diverse than Oklahoma. There's no definition of diversity in which Oklahoma is the clearcut winner.
Feel free to discuss the Alaska and California cases. And to define diversity any way you'd like. I'd love to hear how Oklahoma's 39 tribes are more diverse than Alaska's 250+ or California's 109.
