The term African American has been adopted in the United States since the 1970s as the preferred term for black Americans, as requested by some black Americans themselves. Advocacy for its use has sometimes been criticized as due to political correctness; those who prefer it say it is a matter of respect and politeness.
The term is subject to accidental or intentional misuse in that it defines a group both in terms of race and in terms of citizenship. This can make clear discussion of topics related to race difficult. When speaking specifically of black United States citizens, the term is correct, but when speaking of all black people, "African American" is inappropriate for obvious reasons.
