Does it even matter what race someone puts down on those? On the last US census I put my race as human, although technically (and visually) I am white, but my background is such a mutt, or not traced, that it doesn't really matter anyway. On top of that I grew up in a city thats over 60% (south Texas) Hispanic. That will change my views to be more "Hispanic like" vs someone with the exact same racial qualities living in, say, NY. Hell when I go to home depot they say things in English then Spanish on the intercoms.
It also seems lately that half the people I meet are half Mexican and half white. What should they put? Every one I have asked puts Hispanic because in general they get more that way.
I guess it comes down to an obviously flawed system. Possibly "diversify" based on income, or location over race.
