Total unemployment rate supposedly counts workers who stopped looking. The government includes it in U6 column. I can't even conceive how they calculate U5 and U6. I think they it must involve guesstimating? Here's the link. I didn't know they are claiming to calculate that part of the unemployment rate. So I'm reading the total unemployment rate between 10-11 percent--which still seems overly optimistic?
