A new report by the Silicon Valley Leadership Group ranks the Raleigh-Durham-Chapel Hill NC Research Triangle as the top U.S. tech center. Silicon Valley ranked last.

The rankings are based on "unemployment rate, the percentage of people able to afford a median-priced home, traffic congestion, 8th-grade math achievement, cost of electricity and state taxes."

According to that same article, "Seattle comes in second, followed by Denver, Austin, Texas, and Portland, Ore. Denver was new to the list of comparisons this year, as was Philadelphia (6), Washington, D.C., (7), Chicago (8) and New York (10). Boston was ninth and San Diego was 11th, next to last."

Silicon Valley, however, still ranks tops in venture capital with nearly $8 billion in capital investment, which is nearly as much as all competitors combined and nearly four times as much as Boston, their nearest competitor.
