The Seattle metropolitan area in the U.S. state of Washington includes the city of Seattle, King County, Snohomish County, and Pierce County within the Puget Sound region. About 3.73 million people were living in the Seattle metro area, which is more than half of Washington's total population in 2015 (about 7.17 million people).
This makes the Seattle metro area the 15th largest metropolitan area in the United States, by population.
However, Seattle is on the fifth place among the 20 largest metro areas in terms of household income, which stood at 63,100 U.S. dollars in 2010. This is by far more than the average household income in the United States.
Household income in Washington is on a similar high level. In 2013, federal state of Washington was ranked 13th in terms of household income among the states of the U.S.
The city of Seattle is the largest city in the Pacific Northwest region of North America. It has about 684 thousand residents and is among the 25 largest cities in the United States.
Seattle has always been an important coastal seaport city and a gateway to Alaska. The importance of the city and metro area is also due to fact that some of the biggest companies worldwide started in Seattle during the 1980s. Companies like Amazon and Microsoft are still based in the Seattle area in the state of Washington.
