Salem was founded in 1842, became the capital of the Oregon Territory in 1851, and was incorporated in 1857. Salem had a population of 175,535 at the 2020 census, making it the 3rd most populous city in the state after Portland and Eugene. Salem is the principal city of the Salem Metropolitan Statistical Area, a metropolitan area that covers Marion and Polk counties and had a combined population of 433,353 at the 2020 census. This area is, in turn, part of the Portland–Vancouver–Salem Combined Statistical Area. The city is home to Willamette University, Corban University, and Chemeketa Community College. The State of Oregon is the largest public employer in the city, and Salem Health is the largest private employer.
