Columbia County is one of the 36 counties in the U.S. state of Oregon. As of the 2010 census, the population was 49,351. The county seat is St. Helens.
History
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.

Media and news
Columbia County had newspapers as early as 1891, with the launch of the Clatskanie Chief. The Rainier Review was launched in 1895. The St. Helens Chronicle, which grew out of a series of mergers of the Chronicle, the Sentinel, and the Mist (which was founded in 1881), serves as a newspaper of record for the county. The South County Spotlight, launched in 1961, serves the region along, with a circulation of 3,600. Columbia County has one AM radio station, KOHI AM 1600, which has broadcast continually since 1959. The station is locally owned, with an FCC-estimated weekly listenership of 10,000.
Government
The county is governed by an elected board of three commissioners. Each commissioner is elected to a term of four years. Other elected officials include the sheriff, county clerk, district attorney, treasurer, surveyor, assessor and justice of the peace.
Politics
In presidential elections, the county was, between 1932 and 2012, among the most consistently Democratic in the United States. The last Republican to win a majority in Columbia County had been Herbert Hoover in the 1928 presidential election, although before 1930 no Democrat had won a majority in the county since Samuel J. Tilden in 1876. However in 2016, Donald Trump won the county with just under fifty percent of the vote, a break with the tradition of choosing Democrats for president. Trump would repeat his win in the county 4 years later with an absolute majority of the vote this time - a uniform development for other ancestrally Democratic rural, white working-class counties across the nation in both of his runs.
While Colombia had an 80-year streak of voting for the Democratic nominee, the margin had been as narrow as three percent in 2004 and in 1984.
Columbia County is part of Oregon's 1st congressional district, which is represented by Suzanne Bonamici and has a Cook Partisan Voting Index score of D+8.
Economy
The primary industries are wood products and paper manufacturing, trade, construction and horticulture. The extensive stands of old-growth timber, which had attracted many of the early settlers to the area, were completely logged over by the 1950s. Second-growth timber provides the raw material for local lumber and paper mills. About half the county's workforce commutes out of the county to work, most to the nearby Portland, Oregon, metro area. Columbia County's average non-farm employment was 10,740 in 2007. The five largest private employers in Columbia County are Fred Meyer, Cascade Tissue Group, Wal-Mart, OMIC, USIA, and USG.
Transportation
Public transit
Columbia County Rider (CC Rider), a service of the Columbia County Transit Division, provides six intercity bus lines and one "flex route" serving various points of downtown St. Helens and downtown Scappoose. As of 2016, CC Rider buses are operated by contract drivers supplied by MTR Western, a charter motor coach operator.
The transit agency is largely funded by grants from the Oregon Department of Transportation and the federal government. Attempts at making CC Rider a separate transit district and to introduce new taxes to fund it have repeatedly failed since 2015. Columbia County and nearby Clatsop County are currently studying options on consolidating the two county's transit services.
Single-ride fares range from $2 to $6 per ride, depending on number of zones traveled. A ride to Astoria costs up to $10 per ride each way.
