black and african americans are citizens and residents of the united states with origins in sub-saharan africa. according to the office of management and budget, the grouping includes individuals who self-identify as african-american, as well as persons who emigrated from nations in the caribbean and sub-saharan africa who may alternatively identify as black or some other written-in race versus african-american given they were not part of the historic us slave system. in this case, grouping is thus based on the geography of the individual, and may contradict or misrepresent their self-identification, for instance not all immigrants from sub-saharan africa are "black". among these racial outliers are persons from cape verde, madagascar, various hamito-semitic populations in east africa and the sahel, and the afrikaners of southern africa including such notable figures as the inventor elon musk and actress charlize theron.
