Actually, statistics are separated into "white/non-hispanic" and "white/hispanic". That was done because the "white/hispanic" figures were being diluted by the "white/non-hispanic". When isolated, the "white/hispanic" rates are significantly higher than the "white/non-hispanic".
Read somewhere there are only 3 classifications for race: Caucasian, Asian and Black. (I think everything south of the Himalayans was considered Asian???) I was angry at the recent census trying to divide us all by racial ancestry and color...they had race broken into about ten different categories. I refused to put Caucasian,my friends and I put AMERICAN since they were trying to pigeonhole us all by ancestry in the census. Hey, if we were born here we are and should be classified as American with no further inquiries as to race. Got a nasty form letter back but no further follow up.
