Technology-industry hiring is on an upswing, with vacancies outnumbering job seekers by more than three to one, according to the Conference Board. Online help-wanted advertisements for people with computer and math skills rose 2.1% in February from a month earlier to the second- highest level since the Conference Board began tracking the data seven years ago. Job openings for people skilled in mobile applications are up more than 100%.

A study released in January by economists Robert Shapiro and Kevin Hassett found that more than 1.5 million jobs were created from April 2007 to June 2011 by the shift from 2G to 3G Internet and wireless network technologies. Going forward, the U.S. will need about 490,000 people with “deep analytical skills” and another 1.5 million data-savvy managers, according to a report by McKinsey Global Institute.
