History
Summarize
Perspective
The area of the lower Willamette River has been inhabited for thousands of years, including by the Multnomah band of Chinookan peoples long before European contact, as evidenced by the nearby Cathlapotle village, just downstream.[4]
Multnomah County (the 13th in Oregon Territory) was created on December 22, 1854, formed out of two other Oregon counties – the eastern part of Washington County and the northern part of Clackamas County. Its creation was a result of a petition earlier that year by businessmen in Portland complaining of the inconvenient location of the Washington County seat in Hillsboro and of the share of Portland tax revenues leaving the city to support Washington County farmers. County commissioners met for the first time on January 17, 1855.[5]
The county is named after the Chinookan word for the "lower river", multnomah, matlnomaq, or máɬnumax̣ being interpretive English spellings of the same word. In Chinook jargon, Ne-matlnomaq, means the "place of matlnomaq" or the (singular) Ne-matlnomag, "the lower river", from the Oregon City Falls toward the Columbia River. Alternatively, Chinookan máɬnumax̣ (also nímaɬnumax̣) "those toward water" (or "toward the Columbia River", known in Chinookan as ímaɬ or wímaɬ, "the great water"). Explorer William Clark wrote in his journal: "I entered this river...called Multnomah...from a nation who reside on Wappato Island, a little below the enterence" (quoted from Willamette Landings by H.M. Corning).(see:Portland Basin Chinookan Villages in the early 1800s, Boyd and Zenk,) Although Clark refers to the Willamette River as Multnomah, he may not have understood the meaning. Simply put, Multnomah ("down river" or "toward the great water") is the shortened form of nematlnomaq/nímaɬnumax̣.
In 1924, the county's three commissioners were indicted and recalled by voters "in response to 'gross irregularities' in the award of contracts for construction of the Burnside and Ross Island bridges"; since all three had been supported by the Ku Klux Klan, their recall also helped reduce that organization's influence in the city.[6]
Vanport, built north of Portland in 1943 to house workers for Kaiser Shipyards, was destroyed by a flood five years later.
In 1968, the Oregon Legislative Assembly referred a bill, Ballot Measure 5, to voters that would amend the state constitution to allow for consolidated city-county governments when their populations are over 300,000.[7] The 1968 voters' pamphlet noted that Multnomah County would be the only county in Oregon affected by the measure and voters approved the referendum in the 1968 general election.[7][8] Since the approval of Measure 5 in 1968, an initiative to merge the county with Portland has been considered and placed on the county ballot several times.[9][10][11]
Since 2000
In the 2000 presidential election, Multnomah county played a decisive role in determining the winner of the state's electoral votes. Al Gore carried the county by 104,764 votes, enough to offset the 97,999 vote advantage that George W. Bush had earned among Oregon's 35 other counties.[12] The Democratic tilt was repeated in 2004, when John Kerry won by 161,146 votes,[13] and in 2008, when Barack Obama won by 204,525 votes.[14]
In February 2001, the Multnomah County Board of Commissioners unanimously accepted the recommendation of the Library Advisory Board and authorized the library to enter into a lawsuit to stop the Children's Internet Protection Act.[15] The US Supreme Court ultimately decided in 2003 that the law was constitutional in US v. ALA. However, the library chose to turn down $104,000 per year of federal funding under CIPA to be able to continue to offer unfiltered Internet access.[16][15]
Faced with decreasing government revenues due to a recession in the local economy, voters approved a three-year local income tax (Measure 26–48) [17] on May 20, 2003, to prevent further cuts in schools, police protection, and social services.[18]
After that, though, Linn and the three commissioners developed a public feud, with the latter becoming known as the "mean girls".[19] The county government has also faced significant budget issues, including not being able to open the Wapato Corrections Facility since it was built in 2003.
Geography
According to the United States Census Bureau, the county has a total area of 466 square miles (1,210 km2), of which 34 square miles (88 km2) (7.4%) are covered by water.[20] It is the smallest county in Oregon by area. It is located along the south side of the Columbia River.
The county includes a number of extinct volcanoes in the Boring Lava Field. The Oregon side of the Columbia River Gorge forms the eastern portion of the county's northern border.

Perspective
Multnomah County was a strongly Republican county for much of the first half of the 20th century. Since 1964, it has been the strongest Democratic bastion in Oregon, even in the Republican landslides of 1972 and 1984.
As Multnomah County is by far the most populous county in Oregon, Democratic majorities in the county are often enough to swing the results in statewide elections. In 2008, Democratic challenger Jeff Merkley unseated incumbent two-term Senator Gordon Smith, though Smith carried 28 of Oregon's 36 counties. Merkley carried Multnomah County by over 142,000 votes, however, enough to allow him to defeat Smith by 59,100 votes.
The county courthouse is located in downtown Portland. The Multnomah County Central Courthouse opened in 2020, replacing a century-old building nearby that was in need of seismic retrofitting.[36]

Joint Office of Homeless Services
The Joint Office of Homeless Services is an agency run by Multnomah County to provide services and care to those experiencing homelessness. The City of Portland contributes 9 percent of its budget.[49]
In 2024, city councilors considered withdrawing from this partnership, but left it in place after the election of mayor Keith Wilson who ran on a platform of ending unshelterd homelessness.[49][50]
Earlier in 2024 it was reported that the JOHS increased people it was able to put into housing by 28 percent compared to 2023.[51]
In February 2025, the JOHS reported a budget gap of $104 million, saying it would not be able to meet its commitments this year.[52]

Economy

Perspective
The principal industries of Multnomah County are manufacturing, transportation, wholesale and retail trade, and tourism. Since Oregon does not have a sales tax, it attracts shoppers from southwest Washington.
The Port of Portland, established in 1891 and combined with the City of Portland's Commission of Public Docks in 1971, ranks third in total waterborne commerce on the West Coast, and 31st in the nation for total tonnage according to the 2009 American Association of Port Authorities' Port Industries Statistics.[55] Portland is one of the five largest auto import ports in the nation and is the West Coast's leading exporter of grain and lumber.[citation needed] The Port of Portland is also responsible for Portland International Airport (PDX) in the northeast section of Portland, the Troutdale Airport a few miles east of PDX in Multnomah County, the Hillsboro Airport to the west in Washington County, and Mulino State Airport to the south in Clackamas County.
Out of the 199 cities and counties located in the five West Coast states, Multnomah County ranked 198th in private sector job creation from 1997 to 2009.[56]
Tourism
The county is home to a number of Portland-area attractions and venues, including Oregon Museum of Science and Industry, Portland Art Museum, Memorial Coliseum, Oregon Convention Center, Moda Center, Providence Park, Washington Park, Oregon Zoo, International Rose Test Garden, Lan Su Chinese Garden, Portland Japanese Garden, Hoyt Arboretum and Pittock Mansion.
It is also home to the Historic Columbia River Highway, Multnomah Falls, and Oxbow Regional Park.
