Black Americans today earn even less relative to their white counterparts than they did in 1979, according to a new report by the Economic Policy Institute (EPI).

The report, released by the left-leaning thinktank on Tuesday, shows that the gap between wages of both black and white men and black and white women has widened over the last 36 years. 

Black men’s average hourly wages went from being 22.2% lower than those of white men in 1979 to being 31% lower by 2015. For women, the wage gap went from 6% in 1979 to 19% in 2015.
