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'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".

Oregon has been home to many indigenous nations for thousands of years. The first European traders, explorers, and settlers began exploring what is now Oregon's Pacific coast in the early to mid-16th century. As early as 1564, the Spanish began sending vessels northeast from the Philippines, riding the Kuroshio Current in a sweeping circular route across the northern part of the Pacific. In 1592, Juan de Fuca undertook detailed mapping and studies of ocean currents in the Pacific Northwest, including the Oregon coast as well as the strait now bearing his name. The Lewis and Clark Expedition traversed Oregon in the early 1800s, and the first permanent European settlements in Oregon were established by fur trappers and traders. In 1843, an autonomous government was formed in the Oregon Country, and the Oregon Territory was created in 1848. Oregon became the 33rd state of the U.S. on February 14, 1859. (Full article...)
Image 8None 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.
