IT workers are in high demand. Almost every company relies on them, whether it's a programmer, software developer or the person you call when your computer goes on the fritz.
"We live in a high-tech world," said Katie Bardaro, PayScale's lead economist. "There's been super-high demand for IT workers over the past seven years."
The perennial shortage in IT staffers stems from the demands of the job. It requires a specific set of knowledge and skills, according to Bardaro.
In fact, unemployment among IT workers is among the lowest in the nation. In February, the industry's jobless rate was 5.2%, about 2.5 percentage points below the national average, according to data from the Bureau of Labor Statistics.
And the pay is high. Median income ranges from about $50,000 to more than $100,000 a year. Pay raises for IT workers outpaced all others over the 12 months ended March 31, reported PayScale.
A CNNMoney analysis of Census data shows these jobs -- which have roughly the same amount of men and women workers -- have little disparity in salaries.
