Map of Polk County

Polk County is one of the 36 counties in the U.S. state of Oregon. As of the 2020 census, the population was 87,433.[1] The county seat is Dallas.[2] The county is named for James Knox Polk, the 11th president of the United States.

Polk County is part of the Salem, OR Metropolitan Statistical Area, which is also included in the Portland-Vancouver-Salem, OR-WA Combined Statistical Area. It is located in the Willamette Valley.

History[edit]

The Oregon Provisional Legislature created Polk County from Yamhill District on December 22, 1845, granting to it the entire southwestern portion of present-day Oregon to the California border. County boundaries were periodically changed to reflect the creation of Benton and Lincoln counties. Many other counties were subsequently carved out of these as settlement spread towards the south, leaving Polk County many counties away from its former border with California.

The first county seat was a settlement on the north side of Rickreall Creek named Cynthian (also known as Cynthia Ann). In 1852 city officials renamed Cynthian to Dallas after Vice President George M. Dallas, vice president (1845–1849) to James Polk. During the 1880s and 1890s, there were a series of unsuccessful efforts to move the county seat to nearby Independence.

Geography[edit]

According to the United States Census Bureau, the county has a total area of 744 square miles (1,930 km2), of which 741 square miles (1,920 km2) is land and 3.1 square miles (8.0 km2) (0.4%) is water.[3]

About two thirds of Polk County, the western part, is forest, mostly of the coniferous and mixed varieties, bordering on temperate rain forest around Laurel Mountain, the wettest place in Oregon.

The eastern half of the county lies in the Willamette Valley. The Willamette River forms the eastern border of the county, separating it from neighboring Marion County.

Politics[edit]

Though Polk County is located in western Oregon, politically it falls in line with the eastern side of the state. The majority of registered voters who are part of a political party in Polk County, as well as most rural counties in Oregon, are members of the Republican Party.[13]

In the 2012 presidential election, 50.54 percent of Polk County voters voted for Republican Mitt Romney, while 46.21 percent voted for Democrat Barack Obama, and 3.25 percent either voted for a Third Party candidate or wrote in a candidate.[14] These numbers show a shift toward the Republican candidate when compared to the 2008 presidential election, in which 48.92% of Polk County voters voted for Republican John McCain, while 48.43 percent voted for Barack Obama, and 2.64 percent either voted for a Third Party candidate or wrote in a candidate.[15] Obama's 2008 performance was the best by a Democrat since Lyndon Johnson carried the county in 1964; the only other Democrats to ever carry Polk County have been Franklin Roosevelt in 1932 and 1936, Woodrow Wilson in 1912, and William Jennings Bryan in 1896. However, Polk's Republican lean has been thinning in recent years. Republicans managed to win 50% or more of the county's vote only three times since 1992.[16]
