Isn't combatting racism part of the reason why the US collects this data? If this categorization is common, that looks like a pretty big blind spot for arabs.
Do south africans and australians with european heritage get categorized as white or african/pacific?
This doesn't seem accurate at all. The census itself doesn't display this info, is it from their website? Race is self reported so I don't get why a origin map is relevant. Also, the US census does not consider hispanic/Latino to be a racial category. Folks who select that option for ethnicity are ALSO asked to select race seperately.
