Nouriel Roubini does the math:
[T]he "official" unemployment rate is 9.1 percent — but the one that includes discouraged workers who have left the labor force or partially unemployment has gone from 16.2 percent to 16.5 percent. And if you add to it the millions of people that you have in jail in the U.S. — which is four times the amount of any civilized country as a share of population — than unemployment is probably closer to 20 percent. And that's just among the average population. For minorities, the youth, or unskilled people that don't have a high school degree, the number is closer to 30 percent.
