First, as a matter of fact, it's pretty clear that a lot of the unemployment rates for blacks are very low, and in fact, that they're lower than they were in the early 1970s. I have this chart from an excellent analysis by the University of Chicago's Kenneth Green showing the average unemployment rate, based on the latest available data, for the years 1982 to 2016. This is the first chart that shows both black unemployment rates and the economy as a whole, since it is impossible to predict unemployment rates without knowing GDP. In the chart I've included both the unemployment rates and the percentage of the employment level that is black-represented, a very useful indication of income inequality. And there are two striking features about this chart. First, it shows that, although there were some very very long periods in which black unemployment levels were much higher, these periods are far less common than in the pre-1973-era period.
