Whilst it has a large Native American population compared to other states, at 7.9% (per Wikipedia) it's not really large enough to make a big impact for the purposes of this quiz. North Dakota is still very white - 73.5%.
Outside of the Northern Virginia DC suburbs, Richmond, and Virginia Beach/Hampton Roads area most of the state is pretty "white" (not really a thing)... but those 3 areas are where most of the population is so yeah maybe it's a little surprising.
Not crazy about demographic quizzes - and the thumbnail doesn't represent the FBI Race codes which are used in the census: A = Asian, B = Black, I = American Indian/Alaskan Native, P = Native Hawaiian/Pacific Islander. the Race & Ethnicity codes are required upon arrest (Latino or not) but increasingly people are declining to identify on the census. Also, the data is manipulated very easily.
