Employment in the information technology sector rose by 1,400 jobs in March, according to a monthly index from TechServe Alliance, a collaboration of IT services firms, clients, consultants and suppliers.

IT jobs were up 0.04 percent in March from February and up 4.1 percent year over year. The number of IT jobs in March totaled almost 4 million.

"While the rate of growth varies month-to-month given the dynamic nature of the economy and the labor market, the addition of nearly 160,000 jobs since a year ago paints a decidedly upbeat picture of demand for IT professionals," said Mark Roberts, CEO of TechServe Alliance. "The data is further confirmed by strong anecdotal reports of our members companies pointing to continued strength in our sector."
