Gist: 67000 jobs added last month but unemployment percentage went up to 9.1%. Why are we so worried about those 9.1% and why is unemployment percentage rising?

According to Richard Moran a quarter of working adults were unemployed in one point during the recession and 9.1% are unemployed now so about one third of the US work force was affected by the recession.
The reason the unemployment number is going up is due to the fact that people are returning to look for jobs now that the job market is awaking. Up until now those people were under the radar.
