The stats have been collected, and when it comes to hubs of STEM jobs (science, technology, engineering, and math), Silicon Valley does not even crack the top five. Steven Musil reports on better spots for CNET.
WalletHub did the research, using 11 metrics like annual median wage growth of STEM jobs to rank the best and worst locations. Seattle and Boston join Silicon Valley in not making the top five, though Seattle at least ranked sixth. Houston and Austin, TX ranked first and second respectively, followed by Raleigh, NC, Denver, and Omaha. Pittsburgh interestingly placed eleventh.
