Thank you HuliOpu.  Another skewing of data happens when politically active researchers, or grant-seekers, decide to count multiracial respondents as though they are solely of the researcher's favorite race.  For example:  A respondent who is 1/8 Hawaiian, 1/2 Caucasian, and 3/8 Chinese factually checks all 3 race boxes, along with a box for having diabetes.  A Papa Ola Lokahi grant-seeker awards a full tally mark for Native Hawaiian diabetes, and not even a partial tally mark for diabetes of Caucasian or Filipino.  That's how data get politically skewed to "prove" that Native Hawaiians have the worst statistics for all bad things, and how grant money gets racialized.
