San Jose, Calif. -- Despite a concentration of tech jobs that's nearly six times the national average, Silicon Valley ranks just No. 17 in Forbes' newly released list of "The Best Cities for Technology Jobs." The publication ranked the nation's 51 largest metro areas, based on high-tech employment data collected by economic modeling firm EMSI. Seattle topped the list, followed by Baltimore; Columbus, Ohio; Raleigh, N.C. and Salt Lake City, Utah. "This relatively low ranking reflects the little known fact that, even with the recent last dot-com craze sparking over 5% growth over the past two years, the Valley remains the `biggest loser' among the nation’s tech regions, surrendering roughly one quarter of its high-tech jobs -- about 80,000 -- in the past decade," Forbes wrote. Only New York City lost more technology jobs over the same span.
