I know that when unemployment goes down or a recession occurs there is a political incentive of the minority part to point out to the "real" unemployment rate wherein they include things like "underemployment" and the fact people have become discouraged and left the labor force. I don't much give credit to these figures, not because they aren't real, but any time there's a recession things like underemployment and discouraged worker occur anyway, regardless of who's in power.
However, for those that were interested, here is the labor force participation rate, which shows about 2% of the labor force has "quit" and stopped looking for jobs. If you want to add that 2% to the current 10.2% you would have a "real" unemployment rate of around 12%.
But don't worry, unemployment will continue to go up, so for those looking for more ammo against the Obama administration, don't worry, it's coming.
