AP style on ethnicity and nationality

AP Style came out with revisions on ethnicity and race in February that give all of the appropriate terms to describe someone's race or nationality. I was surprised to see that "black" was an accepted term to describe someone's race when African-American was also on the list. It was also news to me that a hyphen is needed in between the words African and American as well as Asian-American but not in Native American. Another thing I found surprising and interesting was that Chicano was an acceptable term to describe a Hispanic person along with Latino.
