Negro has gone out. I remember an elderly (now 99 year old) black woman who said in the 80s, “I’ve been a colored person, I’ve been a Negro, African-American and now I’m Black. I can’t keep up with it all.”
Colored and Negro (I don’t know whether to capitalize them or not) survive in titles of organizations like United Negro College Fund and National Association for the Advancement of Colored People but not used in polite conversation or in any sentence without an historical referent or context.* The 40 colleges supported by the UNCF, however, are now called “historically black colleges”. Even what we used to call “Negro Spirituals” are now delineated as “African American Spirituals” in the hymnals I reference.
*"Person of Color” is often used but it means “non-white” (Asian, Hispanic, American Indian, Black folk and the like) not “colored person” which meant a black person of whatever mixed ancestry. The NAACP now thinks of its mission as advocating the rights of “People of Color.” In the calculus used in my youth, if a person had one drop of Negro blood, they were legally Negro, especially for the purposes of the anti-miscegenation laws and other such prohibitions, caveats and restrictive housing covenants.
