I wonder how much of this increase is due to the way unemployment is calculated. When workers stop looking for a job, they are no longer counted as unemployed.

I wonder how much of this increase is due to the way unemployment is calculated. When workers stop looking for a job, they are no longer counted as unemployed. When they start looking for a job, I assume they are once again counted. Given that we had been hearing a good amount about economic recovery and lowering unemployment, is it possible that formerly discouraged workers got back into the job market? Nothing fundamental seems to have changed since 6 months ago.
