I RAN ACROSS THESE NUMBERS WHILE DOING SOME RESEARCH ON BLACK HISTORY…CHECK THIS OUT…..
The black population of the United States in 1870 was 4.8 million; in 2007, the number of black residents of the United States, including those of more than one race, was 40.7 million.
Population
44.5 million
The number of blacks, either alone or in combination with one or more other races, on July 1, 2012, up 1.0 percent from July 1, 2011.
77.4 million
The projected black, either alone or in combination, population of the United States (including those of more than one race) for July 1, 2060. On that date, according to the projection, blacks would constitute 18.4 percent of the nation’s total population.
