According to new report from the National Science Foundation, in 2013, there were 1,142,000 scientists and engineers employed in the United States who held the credential of a doctoral degree. Of these, 46,000 were African Americans. Thus, Blacks made up 4 percent of all employed scientists and engineers who held doctoral degrees.
In some fields, the Black percentage of employed scientists and engineers was lower. For example, Blacks with doctoral degrees made up 3.1 percent of the employed computer scientists, 1.9 of the physical scientists, and 1.7 percent of the engineers.
