“Over the past decade, Seattle has added 220,000 jobs, an increase of nearly 15 percent. Amazon, which employs 40,000 people here and holds about one-fifth of the city’s premier office space, has keyed that growth, but the revival has spilled far beyond it. Thirty-one Fortune 500 companies now operate research and engineering hubs in Seattle, up from seven in 2010. More construction cranes are working here than in any other U.S. city, many in the South Lake Union area where Amazon has centered its burgeoning operations. Seattle is now adding about 60 people daily, many of them well-educated Millennials. That’s the city’s most rapid rate of population increase since the Klondike Gold Rush around 1900.”
