Multnomah County, Oregon is the most populous county in the U.S. state of Oregon, anchored by the major city of Portland. Established in 1854, it is a central hub for government, commerce, and culture in the Pacific Northwest. The county is named for the Multnomah people, a band of the Chinookan peoples who historically inhabited the southern banks of the Columbia River.

History

The land within the county has been inhabited for millennia by indigenous peoples, including the Multnomah, Cascades, and other Chinookan peoples. European and American exploration began with figures like Meriwether Lewis and William Clark of the Lewis and Clark Expedition, who camped in the area in 1805-1806. Permanent American settlement accelerated with the arrival of the Oregon Trail pioneers, and the community of Portland was platted in 1845. The county was carved from the eastern portion of Washington County and the northern part of Clackamas County in 1854. Key historical events include the devastating Portland Fire of 1873 and the city's rise as a major port following the completion of the Northern Pacific Railway connection. The 20th century saw significant growth driven by wartime industry, such as the Kaiser Shipyards during World War II, and later by the rise of the Silicon Forest technology sector.

Geography

According to the United States Census Bureau, the county has a total area of 466 square miles, of which 431 square miles is land and 35 square miles is water. Its geography is defined by the Columbia River to the north, which forms the border with Washington, and the Willamette River flowing through its center. The eastern boundary is marked by the dramatic cliffs of the Columbia River Gorge, a National Scenic Area, while the western reaches extend into the Tualatin Mountains (West Hills). Dominating the eastern skyline is the dormant volcano Mount Hood, located in the Mount Hood National Forest just outside the county line. Other significant natural features include the Sandy River and the Tryon Creek State Natural Area.

Demographics

As of the 2020 United States Census, the population was 815,428, making it the most populous county in Oregon. The racial and ethnic composition is diverse, with significant non-Hispanic White, Asian, Hispanic or Latino, and Black communities. The county is a center for immigrants and refugees, with vibrant communities from places like Vietnam, Mexico, Russia, and Somalia. Major educational institutions, including Portland State University and Reed College, contribute to a highly educated population. The United States Census data indicates a high population density, largely concentrated within the urban growth boundary surrounding Portland and cities like Gresham and Troutdale.

Government and politics

Multnomah County operates under a charter with a Board of County Commissioners and a County Chair, currently led by Jessica Vega Pederson. Key county responsibilities include the Multnomah County Sheriff's Office, the Multnomah County Library system, and public health services through the Multnomah County Health Department. The county is a stronghold for the Democratic Party; it has voted for Democratic presidential candidates in every election since Lyndon B. Johnson in 1964. Notable political figures from the area include former U.S. Senators Mark Hatfield and Ron Wyden, and former Portland Mayor Bud Clark. Voters have also passed numerous local ballot measures, such as those supporting the Portland Streetcar and funding for Portland Public Schools.
