Seattle Population Growth

Seattle has been undergoing a population boom over the last decade and, according to recent Census data, it had the 14th largest population increase in the country, adding more than 12,600 residents between 2011 and 2012.

Seattle has struggled with its population growth, and it has experienced trouble creating space for more residents. Planners in 2006 projected the population would grow an additional 200,000 by 2040, and work has been underway to construct apartment buildings to house new residents. Since 2009, the downtown area alone has experienced a growth of 77% in twenty years.

By 2040, the larger Seattle area is expected to grow by 1.7 million people, with a total of 782,00 in Seattle proper by 2040.

The Seattle area was inhabited by Native Americans for about 4,000 years before the first European settlements. The first European to visit the area was George Vancouver in 1792 during an expedition to chart the region. In 1851, members of the Denny Party founded the village of Dewamps, which was later renamed Seattle after Chief Sealth of the Suquamish and Duwamish tribes. Seattle was incorporated in 1865.

Seattle's early history experienced many boom-and-bust cycles like other areas near natural and mineral resources. The first boom covered the lumber industry, although there were tensions between management and labor and ethnic tensions culminating in the anti-Chinese riots of the late 19th century. The Klondike Gold Rush caused the second boom and bust. After this, Seattle became a major center for transportation. It was during this time that American Messenger Company (which became UPS) was founded in the area. There was also a shipbuilding boom during World War I that nearly turned Seattle into a company town.

Today, Seattle's economy is more diverse and involves several major technology companies -- including Nintendo of America and Amazon.com -- and biomedical corporations like Eli Lily and Company and Boston Scientific. Seattle now ranks high for the quality of living, sanitation, crime, recreation, and public services.
