Sidney Poitier isn't an African American.

His parents were Bahamian, but he was born in Florida while they visited. He's Bahamian-American, not African-American.

Actors train to ditch their regional accents. Poitier sounds like he acquired the Mid-Atlantic or Transatlantic accent favored by actors like Grace Kelly, Cary Grant, Douglas Fairbanks Jr, Bette Davis and Joan Crawford. I hear a little Bahamian accent from him during his interviews.

Nope. Musk's ethnicities are Afrikaan, British, Dutch, and French Huguenot. He has South African, Canadian and American citizenship. Besides the ethnic groups I previously listed, you can say he is South African on his father's side and Canadian on his mother's.

African-American is a term specifically used for the ethnic group descended from West and Central Africa people who were brought to the U.S. during the slave trade centuries ago. They have mixed African heritage which is the reason for the very generalized term instead of a specific location. They also share a history, struggle and culture.

Interestingly, there are African-Americans who settled in Liberia during the 1800s, but they recently fled and have migrated to the U.S.. They are ethnically Americo-Liberians.

Amateurs tend to label all black people in the diaspora as one group, but that isn't the case. Obama is really Kenyan-American. V.P. Kamala Harris is Jamaican or West Indian or Caribbean and East Indian. Maria Carey is part Afro-Latina or Afro-Venezuelan.
