Pacific Northwest - Population

Population

Most of the population of the Pacific Northwest is concentrated in the Portland–Seattle–Vancouver corridor. This area is sometimes seen as a megacity (also known as a conurbation, an agglomeration, or a megalopolis). This "megacity" stretches along Interstate 5 in the states of Oregon and Washington and Hwy 99 in the province of British Columbia. As of 2004, the combined populations of the Greater Vancouver/Lower Mainland area, the Seattle metropolitan area and the Portland metropolitan area totaled almost nine million people.
