One obvious problem is that this website counts Hispanic as a separate race and the Census Bureau does not.
You sure about that? With such a large Hispanic population in this country, I find it hard to believe that our pc-infected government wouldn't list them as a separate ethnic group.
My county, Kern County CA, pop 839,631;
White 39% -1% since 2,000
Black 5% +5% since 2,000
Hispanic 49% +63% since 2,000
