When they show me a document explaining that a #9 code for race means “African”, than I will be impressed.
Surely that’s not how Negro was denoted at the time?
I think "Negro" may have been used in the 1960s.
I haven’t read all the comments yet, so forgive if I repeat what someone else has said.
If #9 in 1961 actually meant “other non-white”
then explain how they got from “African” to #9 (other NON-white)
when Africa had many WHITE people living in it in 1961.
“African” tells nothing about race, so how would anyone like the perfectionist Ms. Lee ASSUME “non-white”?
