Washington (i//) is a state in the Pacific Northwest region of the United States located north of Oregon, west of Idaho, and south of the Canadian province of British Columbia on the coast of the Pacific Ocean. Named after George Washington, the first President of the United States, the state was carved out of the western part of the Washington Territory which had been ceded by Britain in 1846 by the Oregon Treaty as a settlement of the Oregon Boundary Dispute. It was admitted to the Union as the 42nd state in 1889.
Washington is the 18th most extensive and the 13th most populous of the 50 United States. Approximately 60 percent of Washington's residents live in the Seattle metropolitan area, the center of transportation, business, and industry along the Puget Sound region of the Salish Sea, an inlet of the Pacific consisting of numerous islands, deep fjords, and bays carved out by glaciers. The remainder of the state consists of deep rainforests in the west, mountain ranges in the west, center, northeast and far southeast, and a semi-arid eastern basin given over to intensive agriculture. After California, Washington is the second most populous state on the West Coast and in the Western United States.
Washington is a leading lumber producer. Its rugged surface is rich in stands of Douglas fir, hemlock, ponderosa and white pine, spruce, larch, and cedar. The state is the biggest producer of apples, lentils, dry edible peas, hops, pears, red raspberries, spearmint oil, and sweet cherries, and ranks high in the production of apricots, asparagus, grapes, peppermint oil, and potatoes. Livestock and livestock products make important contributions to total farm revenue and the commercial fishing catch of salmon, halibut, and bottomfish makes a significant contribution to the state's economy.
Manufacturing industries in Washington include aircraft and missiles, shipbuilding and other transportation equipment, lumber, food processing, metals and metal products, chemicals, and machinery. Washington has over 1,000 dams, including the Grand Coulee Dam, built for a variety of purposes including irrigation, power, flood control, and water storage.
Although the proper vernacular should be "The State of Washington," it is often reversed and referred to as "Washington State" to distinguish it from Washington, D.C., also named for George Washington. Another nickname is "the Evergreen State." Its largest city is Seattle, situated in the west, followed by Spokane, located in the east, and its capital is Olympia.
