The number of high-tech jobs in Silicon Valley industries declined by 86,000, or 16.5%, between 2001 and 2008, according the U.S. Bureau of Labor Statistics.
In a study on employment trends, the bureau identified 11 industries as high-tech employers in Silicon Valley and then assessed changes in their workforce and payroll numbers after the 2001 dot-com bust.
The BLS found that while payrolls in those industries increased by nearly 36% between 2001 and 2008, only three of the 11 industries -- aerospace, pharmaceuticals and scientific research -- boosted their Silicon Valley workforce numbers.
The results may suggest that those who "continue to be employed in Silicon Valley are a higher skill-set people," said Mark Roberts, executive director of the TechServe Alliance, an IT services trade group. "Silicon Valley may well be shedding individuals that possess lower skills [and do] work that can be performed in other areas of the country."
