The workforce is even more stratified by race than you'd imagine. The differences in unemployment rates, participation rates, and average earnings between whites, blacks, and Hispanics aren't just stark. They're also sturdy, rarely yielding over the last 40 years. The racial gaps are stark at the job level, too. Whites account for about 81 percent of the workforce. But there are 33 occupations counted by the BLS (particularly those on farms, around heavy machines, in doctor's offices, and in C-suites) where whites officially account for nine in ten of all workers, or more. Here they are.
