Seattle is a seaport city on the West Coast of the United States. With a population of approximately 747,300, it is the largest city in both the state of Washington and the Pacific Northwest region of North America. The Seattle metropolitan area's population is 3.98 million, making it the 15th-largest in the United States.
Seattle's economy is driven by a mix of older industrial companies, and "new economy" Internet and technology companies, service, design, and clean technology companies. The city's gross metropolitan product was $231 billion in 2010, making it the 11th largest metropolitan economy in the United States. The Port of Seattle, which also operates Seattle–Tacoma International Airport, is a major gateway for trade with Asia and cruises to Alaska. It also is the 8th largest port in the United States when measured by container capacity. Its maritime cargo operations merged with the Port of Tacoma in 2015 to form the Northwest Seaport Alliance.
Seattle is located between the saltwater Puget Sound to the west and Lake Washington to the east. The city's chief harbor, Elliott Bay, is part of Puget Sound, which makes the city an oceanic port. To the west, beyond Puget Sound, are the Kitsap Peninsula and the Olympic Mountains on the Olympic Peninsula; to the east, beyond Lake Washington and the Eastside suburbs, are Lake Sammamish and the Cascade Range. Lake Washington's waters flow to Puget Sound through the Lake Washington Ship Canal - consisting of two man-made canals, Lake Union, and the Hiram M. Chittenden Locks at Salmon Bay, ending in Shilshole Bay on Puget Sound.
Among Seattle's prominent annual fairs and festivals are the 24-day Seattle International Film Festival, Northwest Folklife over the Memorial Day weekend, numerous Seafair events throughout July and August, the Bite of Seattle, one of the largest Gay Pride festivals in the United States, and the art and music festival Bumbershoot, which programs music as well as other art and entertainment over the Labor Day weekend. All are typically attended by 100,000 people annually, as are the Seattle Hempfest and Independence Day celebrations.
