What is the difference between a Black and an African-American?
What is the difference between a white and a caucasian?
I know official databases where each of the above pairs makes no sense at all. There is no standard definition.
I work with several black people who are not African-Americans. They are Haitians not American.
Also, I have a neighbor who is an African, but is as lily white as I am. He’s from South Africa.
