That doesn't wash because this coding was for the Census, not for the parents. Each code corresponded to a specific designation. Tell the detractors to "try again". Besides, the code for "other non-white" was 7.
Code 9 means not stated or unknown. Charlize would be white, and if she was born in Hawaii, how would she be African? ;^)
Sometimes, they just jump right in...
Sorry. I wasn’t being thorough enough. I meant to use the hypothetical that Charlize was born to African white parents in Hawaii.
