The Northwestern United States is an informal geographic region of the United States. The region consistently includes the states of Oregon, Washington and Idaho—and usually Montana and Wyoming. Some sources include Southeast Alaska in the Northwest. The related but distinct term "Pacific Northwest" generally excludes areas from the Rockies eastward.
The Northwestern United States is a subportion of the Western United States (which is, itself, even more ambiguous). In contrast, states included in the neighboring regions (Southwestern United States and Great Plains) and Utah are not simultaneously considered part of both regions.
Like the southwestern United States, the Northwest definition has moved westward over time. The current area includes the old Oregon Territory (created in 1848–Oregon, Washington, Idaho, and areas in Montana west of the Continental Divide).
It is home to over 14.2 million people. Some of the fastest growing cities in this region and in the nation include Seattle, Spokane, Bellevue, Tacoma, Vancouver, Kennewick, Pasco, Yakima, Portland, Eugene, Salem, Boise, Missoula, and Billings.
