To a degree, yes. To a degree because I don't look African. Instead, people think I'm some kind of afrolatino. That said, a lot of black people from certain regions share some traits. I can even tell black people within the US from one place to another generally. Yes, a black person from Atlanta, for whatever reason, looks vastly different from a black person from Oakland. There are always exceptions but a lot of things stick out to me, so I'm never surprised when they say they are from this or that place.
