Black people United States
In the United States the one-drop rule is sometimes used to decide whether a person is black. This is one of the reasons that black people do not all have dark skin. For example, the American singer Mariah Carey is black because she has a black father. Black people can also have light skin because of illness. Michael Jackson, another American singer, was born with brown skin but his skin became light because of a disease called vitiligo. A black person may be called white by other black people if they do not associate themselves with black culture. White people may also be called black.
