In the U.S. census race definitions, 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. The grouping is thus based on geography, and may contradict or misrepresent an individual's self-identification since not all immigrants from Sub-Saharan Africa are "Black". The Census Bureau also notes that these classifications are socio-political constructs and should not be interpreted as scientific or anthropological.
