Earlier this summer, the Brookings Institution released a report about the “Hidden STEM Economy” in America. (Click here to see the report’s web page.) The analysis found that 26 million U.S. jobs—20 percent of all jobs—require a high level of knowledge in any one STEM field, as of 2011.

The report also examined the STEM economy in metropolitan areas, including Seattle-Tacoma-Bellevue. Here is that profile (click to enlarge):
