The Northwest Coast is the coastal region of the Pacific Northwest, and the Northwest Plateau (also commonly known as "the Interior" in British Columbia), is the inland region. The term "Pacific Northwest" should not be confused with the Northwest Territory (also known as the Great Northwest, a historical term in the United States) or the Northwest Territories of Canada. The region is sometimes referred to as Cascadia, which, depending on the borders, may or may not be the same thing as the Pacific Northwest.
The region's largest metropolitan areas are Greater Seattle, Washington, with 4 million people; Metro Vancouver, British Columbia, with 2.84 million people; and Greater Portland, Oregon, with 2.5 million people.
The culture of the Pacific Northwest is influenced by the Canada–United States border, which the United States and the United Kingdom established at a time when the region's inhabitants were composed mostly of indigenous peoples. Two sections of the border—one along the 49th parallel south of British Columbia and one between the Alaska Panhandle and northern British Columbia—have left a great impact on the region. According to Canadian historian Ken Coates, the border has not merely influenced the Pacific Northwest—rather, "the region's history and character have been determined by the boundary".

Article XI of the Washington State Constitution addresses the organization of counties. New counties must have a population of at least 2,000 and no county can be reduced to a population below 4,000 due to partitioning to create a new county. To alter the area of a county, the state constitution requires a petition of the "majority of the voters" in that area. A number of county partition proposals in the 1990s interpreted this as a majority of people who voted, until a 1998 ruling by the Washington Supreme Court clarified that they would need a majority of registered voters. No changes to counties have been made since the formation of Pend Oreille County in 1911, except when the small area of Cliffdell was moved from Kittitas to Yakima County in 1970. (Full article...)

Image 10None of the multiple possible definitions of the Pacific Northwest is universally accepted. This map shows three possibilities: (1) The shaded area shows the historical Oregon Country. (2) The green line shows the Cascadia bioregion. (3) The labeled states and provinces include Washington, Idaho, Oregon and British Columbia. (from Pacific Northwest)

Vancouver's SkyTrain rapid transit system achieves daily ridership of over 500,000 passengers per day on weekdays and the overall transit ridership levels in the Metro Vancouver area rank third in North America per capita.
