turns out that this chart is very misleading. Though it doesn't say so,
the incarceration rate for "Black America" is actually for Black
American men, while those of other countries are for total population.
Once women are added in, the black bar on the far right would be much
shorter. Yet it would still be dramatically higher than any other
country. One way of looking at it is that even if the incarceration rate
of Black women was zero, the total rate would still average out to
above 2,000, which is 4x that of the nearest country (Cuba). So the chart is factually wrong, but the point it's making stands.
