Seattle metropolitan area
The Seattle metropolitan area is an urban conglomeration in the U.S. state of Washington that comprises Seattle, its surrounding satellites and suburbs. The United States Census Bureau defines the Seattle–Tacoma–Bellevue, WA metropolitan statistical area as the three most populous counties in the state: King, Pierce, and Snohomish. Seattle has the 15th largest metropolitan statistical area (MSA) in the United States with a population of 4,018,762 as of the 2020 census, over half of Washington's total population.
The area is considered part of the greater Puget Sound region, which largely overlaps with the Seattle Combined Statistical Area (CSA). The Seattle metropolitan area is home to a large tech industry and is the headquarters of several major companies, including Microsoft and Amazon. The area's geography is varied and includes the lowlands around Puget Sound and the Cascade Mountains; the highest peak in the metropolitan area is Mount Rainier, which has a summit elevation of 14,411 feet (4,392 m) and is one of the tallest mountains in the United States.
As defined by the U.S. Census Bureau and the Office of Management and Budget, the Seattle metropolitan area is officially the Seattle–Tacoma–Bellevue, WA metropolitan statistical area (MSA) and consists of:
Based on commuting patterns, the adjacent metropolitan areas of Olympia, Bremerton, and Mount Vernon, along with a few smaller satellite urban areas, are grouped together in a wider labor market region known as the Seattle–Tacoma combined statistical area (CSA), which encompasses most of the Puget Sound region. The population of this wider region was 4,953,389 at the 2020 census and estimated to be 5,105,721 in 2024; the Puget Sound region is home to two-thirds of Washington's population. The Seattle CSA is the 14th largest in the United States and the 13th largest primary census statistical area in the country. The additional metropolitan and micropolitan areas included are:
The Census Bureau adopted metropolitan districts in the 1910 census to create a standard definition for urban areas with industrial activity around a central city. At the time, Seattle had the 22nd largest metropolitan district population at 239,269 people, a 195.8 percent increase from the population of the equivalent area in the 1900 census. The Seattle metropolitan district was expanded to encompass the entirety of Lake Washington in the 1930 census and also included Edmonds in Snohomish County, Des Moines in southern King County, and portions of eastern Bainbridge Island in Kitsap County. The district covered 209.9 square miles (544 km2), of which two-thirds was outside of Seattle proper, and counted a population of 420,663.
The Seattle metropolitan area, successor to the metropolitan district, was expanded in 1949 to encompass all of King County but lose its portions in Kitsap and Snohomish counties. The local chamber of commerce and other leaders had lobbied for a definition that also included all of Kitsap, Pierce, and Snohomish counties in a manner similar to the Portland metropolitan area, which had been expanded to cover four counties in Oregon and southwestern Washington. The Bureau of the Budget (now Office of Management and Budget) added Snohomish County to its definition of the Seattle metropolitan area in 1959. The definition had previously only encompassed King County; local leaders had sought to also include Pierce and Kitsap counties in a "Puget Sound metropolitan area". Snohomish County had protested its inclusion and had sought a separate metropolitan area designation centered on Everett, which did not meet the population threshold of 50,000 residents.
In the 1950 census, a separate metropolitan area for Tacoma was defined that encompassed all of Pierce County. Kitsap County remained part of no metropolitan area despite its connections to both Seattle and Tacoma. The Office of Management and Budget included the area in the Seattle–Tacoma standard consolidated statistical area in 1981; it was replaced in 1983 by the Seattle–Tacoma consolidated metropolitan statistical area (CMSA). The CMSA was expanded to include Bremerton and Olympia after the 1990 census and was the 12th largest in the country at the time. The Office of Management and Budget restructured its classification system in 2003 and created the Seattle–Tacoma–Bellevue metropolitan statistical area to cover the tri-county region. A new Seattle–Tacoma–Olympia combined statistical area (CSA) replaced the CMSA and expanded to cover Island and Mason counties. The Mount Vernon–Anacortes metropolitan area was created in 2003 to encompass Skagit County and added to the Seattle CSA in 2006; the CSA was extended further south to Lewis County through the addition of the Centralia micropolitan area in 2013.
The Seattle metropolitan area covers 6,309 square miles (16,340 km2) of land and water in Western Washington divided between the three counties; King County is the largest county at over 2,115 square miles (5,480 km2), followed by Snohomish and Pierce counties. The region includes portions of the Cascade Range and two active volcanoes, Mount Rainier and Glacier Peak, which can generate lahars that could potentially reach populated areas. The summit of Mount Rainier is the tallest point in Washington at 14,411 feet (4,392 m) above mean sea level; it has 26 glaciers that are visible from much of the region's lowlands. To the west of the metropolitan area is Puget Sound, which forms the second-largest saltwater estuary in the United States and is part of the Salish Sea.
