A new study from TechNet, a bipartisan advocacy group in Washington for technology companies, says that the growth of "apps" -- from Facebook games to iPhone apps -- has generated nearly 500,000 jobs in the United States since 2007.

This study from TechNet is among the first to grapple with job creation tied to apps that include both mobile and Facebook platforms. Last fall, the University of Maryland released a study that estimated that the Facebook App Economy alone generated 183,000 new jobs.

The TechNet study breaks down the U.S. by state and region, in terms of app job density -- apps created about 466,000 jobs in the country.

(Baltimore accounts for nearly 1 percent of App Economy jobs, per the study. You'll find that number in the full report, attached below.)
