Vancouver is a coastal city and major seaport located in the Lower Mainland of southwestern British Columbia, Canada. It is the largest city in British Columbia and in the Pacific Northwest region. It is bounded by the Strait of Georgia, the Fraser River, the Coast Mountains, and the city of Burnaby. Vancouver is named after Captain George Vancouver, a British explorer. The population of the city of Vancouver is 611,869 and the population of Metro Vancouver is 2,249,725 (2007 estimate). Vancouver is also part of the slightly larger Lower Mainland metropolitan area which comprises a total population of 2,524,113. This makes it the largest metropolitan area in Western Canada and the third largest in the country. Vancouver is ethnically diverse, with 52% of city residents and 43% of Metro residents having a first language other than English. The economy of Vancouver has traditionally relied on British Columbia's resource sectors: forestry, mining, fishing and agriculture. It has diversified over time, however, and Vancouver today has a vibrant service industry, a growing tourism industry, and it has become the third-largest film production centre in North America after Los Angeles and New York City, earning it the nickname Hollywood North. Vancouver has had an expansion in high-tech industries, most notably video game development. Vancouver is consistently ranked one of the three most livable cities in the world.
