The number of U.S. information technology jobs rose 0.27 percent in May to more than 4.4 million, according to the TechServe Alliance. With an upward revision in April’s numbers to 0.53 percent growth from 0.24 percent, IT employment increased by 5.4 percent on a year-over-year basis, adding almost 230,000 IT workers.

“I am pleased to see accelerating growth in IT employment reflecting robust demand for talent,” said Mark Roberts, CEO of TechServe Alliance. “Going forward, the greatest risk potentially inhibiting the full potential for IT employment growth in the U.S. is an inadequate supply of talent.”

TechServe Alliance is a collaboration of IT staffing firms, solutions firms, clients, consultants and suppliers.
