[Matrix] Why are all the Zion residents (Zionites?) black?

I noticed that the only white people in that movie were people who were pulled from the matrix. Whats up with that?

They most likely aren't.

We only see them as being black because of American cultural perception (this goes back to miscegenation laws and something called the one drop rule). 

This is similar to how president Barack Obama is considered to be black in America even though his mother is white, and strictly speaking he's as much white as he is black. 

However, in America only people who are 100% white are considered white. This means that even if zion started out with a low percentage of black people, within a few generations they would all be black according to the American view.
