King County is a county located in the U.S. state of Washington. The population was 2,233,163 in the 2018 census estimate, making it the most populous county in Washington, and the 12th-most populous in the United States. The county seat is Seattle, also the state’s most populous city.
King County is one of three Washington counties that are included in the Seattle–Tacoma–Bellevue metropolitan statistical area. (The others are Snohomish County to the north, and Pierce County to the south.) About two-thirds of King County’s population lives in Seattle’s suburbs.
The Metropolitan King County Council, the legislative body of King County, Washington, consists of nine members elected by district. The Council adopts laws, sets policy, and holds final approval over the budget. Its current name and structure is the result of a merger of King County and the Municipality of Metropolitan Seattle, better known as Metro, which was a federated county-city structure responsible for water quality and public transportation.
