So looking at this article - http://www.usatoday.com/news/nation/census/2011-01-06-us-pop... - my quick calculation shows that the US population is growing at about 1.3% annually. Which means there's somewhat more than 7 million new Americans since 2008 (back of the envelope produces a number of 8 million).
Which, combined with the fact that GDP has barely recovered since 2008, kind of invalidates the article - i.e its reasonable to assume that the number of jobs has not actually decreased, but has stayed static, and that that is most likely due to the depression.
This chart shows that there are now 5% fewer jobs than there were at the peak of employment 34 months ago - the lines are scaled relative to prior peak jobs, not relative to population.
