Multnomah County, Oregon

Multnomah County, Oregon
Multnomah County is one of the 36 counties in the U.S. state of Oregon. As of the 2020 census, the county's population was 815,428. Multnomah County is part of the Portland–Vancouver–Hillsboro, OR–WA metropolitan statistical area. Though smallest in area, Multnomah County is the state's most populous county. Its county seat, Portland, is the state's largest city.
History
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.
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.
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.
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. 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. 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.
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. The Democratic tilt was repeated in 2004, when John Kerry won by 161,146 votes, and in 2008, when Barack Obama won by 204,525 votes.
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. 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.
Faced with decreasing government revenues due to a recession in the local economy, voters approved a three-year local income tax (Measure 26–48) on May 20, 2003, to prevent further cuts in schools, police protection, and social services. Multnomah County was one of the few local governments in Oregon to approve such a tax increase.
On March 2, 2004, Multnomah County Chair Diane Linn announced the county would begin granting licenses for same-sex marriages, pursuant to a legal opinion issued by its attorney deeming such marriages lawful under Oregon law. Her announcement was supported by three other commissioners (Serena Cruz, Lisa Naito, and Maria Rojo de Steffey), but criticized by Lonnie Roberts, who represents the eastern part of Multnomah County and was left out of the decision. Within a few days, several groups joined to file a lawsuit to halt the county's action.
After that, though, Linn and the three commissioners developed a public feud, with the latter becoming known as the "mean girls". 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.

Law and government
Multnomah County was a strongly Republican county for much of the first half of the 20th century, but since 1964, it has been the strongest Democratic bastion in Oregon. The Democrats have failed to win a majority in the county only two times since then, in 1972 and 1980.
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.
