Washington is the 18th largest state, with an area of 71,362 square miles (184,827 km2), and the 13th most populous state, with more than 7.4 million people. Approximately 60 percent of Washington's residents live in the Seattle metropolitan area, the center of transportation, business, and industry along Puget Sound, an inlet of the Pacific Ocean consisting of numerous islands, deep fjords, and bays carved out by glaciers. The remainder of the state consists of: deep temperate rainforests in the west; mountain ranges in the west, central, northeast, and far southeast; and a semi-arid basin region in the east, central, and south, given over to intensive agriculture. Washington is the second most populous state on the West Coast and in the Western United States, after California. Mount Rainier, an active stratovolcano, is the state's highest elevation, at almost 14,411 feet (4,392 m), and is the most topographically prominent mountain in the contiguous United States.
Washington is a leading lumber producer. Its rugged surface is rich in stands of Douglas fir, hemlock, ponderosa pine, white pine, spruce, larch, and cedar. The state is the biggest producer of apples, hops, pears, red raspberries, spearmint oil, and sweet cherries, and ranks high in the production of apricots, asparagus, dry edible peas, grapes, lentils, peppermint oil, and potatoes. Livestock and livestock products make important contributions to total farm revenue, and the commercial fishing of salmon, halibut, and bottomfish makes a significant contribution to the state's economy. Washington ranks second only to California in the production of wine.
Manufacturing industries in Washington include aircraft and missiles, ship-building, 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.
Confusion over the state of Washington and the city of Washington, D. C., led to renaming proposals during the statehood process for Washington in 1889, including David Dudley Field II's suggestion to name the new state "Tacoma". These proposals failed to garner support. Washington, D. C.'s, own statehood movement in the 21st century includes a proposal to use the name "State of Washington, Douglass Commonwealth", which would conflict with the current state of Washington. To distinguish it from the national capital, Washington may be referred to as "Washington state", or, in more formal contexts, as "the State of Washington". Residents of Washington (known as "Washingtonians") and the Pacific Northwest simply refer to the state as "Washington", and the nation's capital "Washington, D. C.", "the other Washington", or simply "D. C.".
