Remember when San Antonio Mayor Julian Castro claimed that President Obama has created more than 4.5 million jobs? Well, the real number is a notch or two lower than that.

The number Castro cites is an accurate description of the growth of private-sector jobs since January 2010, when the long, steep slide in employment finally hit bottom. But while a total of 4.5 million jobs sounds great, it’s not the whole picture.

Nonfarm private payrolls hit a post-recession low of 106.8 million that month, according to the U.S. Bureau of Labor Statistics. The figure currently stands at 111.3 million as of July.

While that is indeed a gain of 4.5 million, it’s only a net gain of 300,000 over the course of the Obama administration to date. The private jobs figure stood at 111 million in January 2009, the month Obama took office.
