Annual data released by the U.S. Bureau of Labor Statistics demonstrates the value of an education in the science, technology, engineering, or math fields. Workers employed in computer and math occupations in the cities with the most technology employees earned yearly salaries about 50 percent to 75 percent higher than the overall workforce. Seattle tech workers, for example, had a mean salary of $108,350, or 78 percent more than the $61,000 earned by all workers there. That was the highest tech-worker premium in the 10 largest hubs, followed by Dallas-Fort Worth, Houston, and Austin. The same is true in the burgeoning tech hub of Oakland, CA, where workers in computer and math occupations were paid 70 percent more. Computer and math occupations in Los Angeles, Philadelphia, San Jose, and San Francisco all earn more than 60 percent more than their non-tech counterparts. Although Washington, D.C., is among the largest tech-employing regions, its tech workers had the smallest salary differential, at 54 percent, likely due to the large numbers of federal government workers. Among tech occupations, software developers and systems analysts were the highest in number in nearly all of the largest tech hubs, surpassing computer programmers, network and database administrators, computer research scientists, and computer-support specialists.
