Columbia County, Oregon
Columbia County is one of the 36 counties in the U.S. state of Oregon. As of the 2020 census, the population was 52,589. The county seat is St. Helens.
The Chinook and Clatskanie Native American peoples inhabited this region for centuries prior to the arrival of Robert Gray, captain of the ship Columbia Rediviva, in 1792. The Lewis and Clark Expedition traveled and camped along the Columbia River shore in the area later known as Columbia County in late 1805 and again on their return journey in early 1806.
Columbia County was created in 1854 from the northern half of Washington County. Milton served as the county seat until 1857 when it was moved to St. Helens.
Columbia County has been afflicted by numerous flooding disasters, the most recent in December 2007. Heavy rains caused the Nehalem River to escape its banks and flood the city of Vernonia and rural areas nearby. Columbia County received a presidential disaster declaration for this event.
In the 1910s the Socialist Party of Oregon won a handful of votes. This party was distinct from the better-known SPO which operated throughout the twentieth century.
According to the United States Census Bureau, the county has an area of 688 square miles (1,780 km2), of which 657 square miles (1,700 km2) is land and 31 square miles (80 km2) (4.5%) is water. It is Oregon's third-smallest county by land area and fourth-smallest by total area.
As of the 2010 census, there were 49,351 people, 19,183 households, and 13,516 families living in the county. The population density was 75.1 inhabitants per square mile (29.0/km2). There were 20,698 housing units at an average density of 31.5 units per square mile (12.2 units/km2). The racial makeup of the county was 92.5% white, 1.3% American Indian, 0.9% Asian, 0.4% black or African American, 0.2% Pacific islander, 1.2% from other races, and 3.4% from two or more races. Those of Hispanic or Latino origin made up 4.0% of the population. In terms of ancestry, 26.1% were German, 14.5% were English, 14.4% were Irish, 5.9% were Norwegian, and 4.8% were American.
Of the 19,183 households, 32.0% had children under the age of 18 living with them, 55.5% were married couples living together, 9.8% had a female householder with no husband present, 29.5% were non-families, and 23.3% of all households were made up of individuals.
