Oregon ( // ( listen) ORR-ih-gən)  is a state in the Pacific Northwest region on the West Coast of the United States. The Columbia River delineates much of Oregon's northern boundary with Washington, while the Snake River delineates much of its eastern boundary with Idaho. The parallel 42° north delineates the southern boundary with California and Nevada.
Oregon was inhabited by many indigenous tribes before Western traders, explorers, and settlers arrived. An autonomous government was formed in the Oregon Country in 1843 before the Oregon Territory was created in 1848. Oregon became the 33rd state on February 14, 1859. Today, at 98,000 square miles (250,000 km2), Oregon is the ninth largest and, with a population of 4 million, 27th most populous U.S. state. The capital, Salem, is the second most populous city in Oregon, with 169,798 residents. Portland, with 647,805, ranks as the 26th among U.S. cities. The Portland metropolitan area, which also includes the city of Vancouver, Washington, to the north, ranks the 25th largest metro area in the nation, with a population of 2,453,168.
Oregon is one of the most geographically diverse states in the U.S.,  marked by volcanoes, abundant bodies of water, dense evergreen and mixed forests, as well as high deserts and semi-arid shrublands. At 11,249 feet (3,429 m), Mount Hood, a stratovolcano, is the state's highest point. Oregon's only national park, Crater Lake National Park, comprises the caldera surrounding Crater Lake, the deepest lake in the United States. The state is also home to the single largest organism in the world, Armillaria ostoyae, a fungus that runs beneath 2,200 acres (8.9 km2) of the Malheur National Forest. 
Because of its diverse landscapes and waterways, Oregon's economy is largely powered by various forms of agriculture, fishing, and hydroelectric power. Oregon is also the top timber producer of the contiguous United States, and the timber industry dominated the state's economy in the 20th century.  Technology is another one of Oregon's major economic forces, beginning in the 1970s with the establishment of the Silicon Forest and the expansion of Tektronix and Intel. Sportswear company Nike, Inc., headquartered in Beaverton, is the state's largest public corporation with an annual revenue of $30.6 billion.

The earliest evidence of the name Oregon has Spanish origins. The term "orejón" comes from the historical chronicle Relación de la Alta y Baja California (1598)  written by the new Spaniard Rodrigo Montezuma and made reference to the Columbia River when the Spanish explorers penetrated into the actual North American territory that became part of the Viceroyalty of New Spain. This chronicle is the first topographical and linguistic source with respect to the place name Oregon. There are also two other sources with Spanish origins, such as the name Oregano, which grows in the southern part of the region. It is most probable that the American territory was named by the Spaniards, as there are some populations in Spain such as "Arroyo del Oregón" (which is situated in the province of Ciudad Real), also considering that the individualization in Spanish language "El Orejón" with the mutation of the letter "g" instead of "j". 
Another early use of the name, spelled Ouragon, was in a 1765 petition by Major Robert Rogers to the Kingdom of Great Britain. The term referred to the then-mythical River of the West (the Columbia River). By 1778, the spelling had shifted to Oregon.  In his 1765 petition, Rogers wrote:
One theory is that the name comes from the French word ouragan ("windstorm" or "hurricane"), which was applied to the River of the West based on Native American tales of powerful Chinook winds on the lower Columbia River, or perhaps from firsthand French experience with the Chinook winds of the Great Plains. At the time, the River of the West was thought to rise in western Minnesota and flow west through the Great Plains. 
The name, Oregon, is rounded down phonetically, from Ouve água—Oragua, Or-a-gon, Oregon—given probably by the same Portuguese navigator that named the Farallones after his first officer, and it literally, in a large way, means cascades: 'Hear the waters.' You should steam up the Columbia and hear and feel the waters falling out of the clouds of Mount Hood to understand entirely the full meaning of the name Ouve a água, Oregon. 
Another account, endorsed as the "most plausible explanation" in the book Oregon Geographic Names, was advanced by George R. Stewart in a 1944 article in American Speech. According to Stewart, the name came from an engraver's error in a French map published in the early 18th century, on which the Ouisiconsink (Wisconsin) River was spelled "Ouaricon-sint", broken on two lines with the -sint below, so there appeared to be a river flowing to the west named "Ouaricon".
According to the Oregon Tourism Commission, present-day Oregonians //  pronounce the state's name as "or-uh-gun, never or-ee-gone".  After being drafted by the Detroit Lions in 2002, former Oregon Ducks quarterback Joey Harrington distributed "Orygun" stickers to members of the media as a reminder of how to pronounce the name of his home state.   The stickers are sold by the University of Oregon Bookstore. 
Oregon is 295 miles (475 km) north to south at longest distance, and 395 miles (636 km) east to west. With an area of 98,381 square miles (254,810 km2), Oregon is slightly larger than the United Kingdom. It is the ninth largest state in the United States.  Oregon's highest point is the summit of Mount Hood, at 11,249 feet (3,429 m), and its lowest point is the sea level of the Pacific Ocean along the Oregon Coast.  Oregon's mean elevation is 3,300 feet (1,006 m). Crater Lake National Park is the state's only national park and the site of Crater Lake, the deepest lake in the United States at 1,943 feet (592 m).  Oregon claims the D River as the shortest river in the world,  though the state of Montana makes the same claim of its Roe River.  Oregon is also home to Mill Ends Park (in Portland),  the smallest park in the world at 452 square inches (0.29 m2).
Oregon is split into eight geographical regions. In Western Oregon: Oregon Coast (west of the Coast Range), the Willamette Valley, Rogue Valley, Cascade Range and Klamath Mountains; and in Central and Eastern Oregon: the Columbia Plateau, the High Desert, and the Blue Mountains.
Western Oregon's mountainous regions, home to three of the most prominent mountain peaks of the United States including Mount Hood, were formed by the volcanic activity of the Juan de Fuca Plate, a tectonic plate that poses a continued threat of volcanic activity and earthquakes in the region. The most recent major activity was the 1700 Cascadia earthquake. Washington's Mount St. Helens erupted in 1980, an event visible from northern Oregon and affecting some areas there. 
The Columbia River, which forms much of Oregon's northern border, also played a major role in the region's geological evolution, as well as its economic and cultural development. The Columbia is one of North America's largest rivers, and one of two rivers to cut through the Cascades (the Klamath River in southern Oregon is the other). About 15,000 years ago, the Columbia repeatedly flooded much of Oregon during the Missoula Floods; the modern fertility of the Willamette Valley is largely the result. Plentiful salmon made parts of the river, such as Celilo Falls, hubs of economic activity for thousands of years.
Today, Oregon's landscape varies from rain forest in the Coast Range to barren desert in the southeast, which still meets the technical definition of a frontier. Oregon's geographical center is further west than any of the other 48 contiguous states (although the westernmost point of the lower 48 states is in Washington). Central Oregon's geographical features range from high desert and volcanic rock formations resulting from lava beds. The Oregon Badlands Wilderness is in this region of the state. 
Typical of a western state, Oregon is home to a unique and diverse array of wildlife. Roughly 60 percent of the state is covered in forest,  while the areas west of the Cascades are more densely populated by forest, making up around 80 percent of the landscape. Some 60 percent of Oregon's forests are within federal land.  Oregon is the top timber producer of the lower 48 states.  
- Typical tree species include the Douglas fir (the state tree), as well as redwood, ponderosa pine, western red cedar, and hemlock.  Ponderosa pine are more common in the Blue Mountains in the eastern part of the state and firs are more common in the west.
- Many species of mammals live in the state, which include opossums, shrews, moles, little pocket mice, great basin pocket mice, dark kangaroo mouse, California kangaroo rat, chisel-toothed kangaroo rat, ord's kangaroo rat,  bats, rabbits, pikas, mountain beavers, chipmunks, squirrels, yellow-bellied marmots, beavers (the state mammal), porcupines, coyotes, wolves, foxes  black bears, raccoons, badgers, skunks, antelopes, cougars, bobcats, lynxes, deer, elk, and moose.
- Marine mammals include seals, sea lions, humpback whales, killer whales, gray whales, blue whales, sperm whales, pacific white-sided dolphins, and bottlenose dolphins. 
- Notable birds include American widgeons, mallard ducks, great blue herons, bald eagles, golden eagles, western meadowlarks (the state bird), barn owls, great horned owls, rufous hummingbirds, pileated woodpeckers, wrens, towhees, sparrows, and buntings. 
Moose have not always inhabited the state but came to Oregon in the 1960s; the Wallowa Valley herd numbered about 60 as of 2013 [update].  Gray wolves were extirpated from Oregon around 1930 but have since found their way back; most reside in northeast Oregon, with two packs living in the south-central part.  Although their existence in Oregon is unconfirmed, reports of grizzly bears still turn up, and it is probable some still move into eastern Oregon from Idaho. 
Oregon has three national park sites: Crater Lake National Park in the southern part of the Cascades, John Day Fossil Beds National Monument east of the Cascades, and Lewis and Clark National and State Historical Parks on the north coast.  
Most of Oregon has a generally mild climate, though there is significant variation given the variety of landscapes across the state.  The state's western region (west of the Cascade Range) has an oceanic climate, populated by dense evergreen mixed forests. Western Oregon's climate is heavily influenced by the Pacific Ocean; the western third of Oregon is very wet in the winter, moderately to very wet during the spring and fall, and dry during the summer. The relative humidity of Western Oregon is high except during summer days, which are semi-dry to semi-humid; Eastern Oregon typically sees low humidity year-round. 
Oregon's northeastern portion has a steppe climate, and its high terrain regions have a subarctic climate. Like Western Europe, Oregon, and the Pacific Northwest in general, is considered warm for its latitude, and the state has far milder winters at a given elevation than comparable latitudes elsewhere in North America, such as the Upper Midwest, Ontario, Quebec and New England.  However, the state ranks fifth for coolest summer temperatures of any state in the country, after Maine, Idaho, Wyoming, and Alaska. 
The eastern two thirds of Oregon, which largely comprise high desert, have cold, snowy winters and very dry summers. Much of the east is semiarid to arid like the rest of the Great Basin, though the Blue Mountains are wet enough to support extensive forests. Most of Oregon receives significant snowfall, but the Willamette Valley, where 60 percent of the population lives,  has considerably milder winters for its latitude and typically only sees light snowfall. 
Humans have inhabited the area that is now Oregon for at least 15,000 years. In recorded history, mentions of the land date to as early as the 16th century. During the 18th and 19th centuries, European powers – and later the United States – quarreled over possession of the region until 1846, when the U.S. and Great Britain finalized division of the region. Oregon became a state on February 14, 1859, and as of 2015 [update] is home to over 4 million residents. 
While there is considerable evidence that Paleo-Indians inhabited the region, the oldest evidence of habitation in Oregon was found at Fort Rock Cave and the Paisley Caves in Lake County. Archaeologist Luther Cressman dated material from Fort Rock to 13,200 years ago,  and there is evidence supporting inhabitants in the region at least 15,000 years ago.  By 8000 BC there were settlements throughout the state, with populations concentrated along the lower Columbia River, in the western valleys, and around coastal estuaries.
During the prehistoric period, the Willamette Valley region was flooded after the collapse of glacial dams from then Lake Missoula, located in what would later become Montana. These massive floods occurred during the last glacial period and filled the valley with 300 to 400 feet (91 to 122 m) of water. 
By the 16th century, Oregon was home to many Native American groups, including the Chinook, Coquille ( Ko-Kwell), Bannock, Chasta, Kalapuya, Klamath, Klickitat, Molalla, Nez Perce, Takelma, Killamuk, Neah-kah-nie, Umatilla, and Umpqua.    
The first Europeans to visit Oregon were Spanish explorers led by Juan Rodríguez Cabrillo, who sighted southern Oregon off the Pacific coast in 1543.  Sailing Golden Hind in search of the Strait of Anian, the English explorer and privateer Sir Francis Drake briefly sought shelter anchoring at South Cove, Cape Arago, just south of Coos Bay, Oregon, before sailing for what is now California.   Exploration was retaken routinely in 1774, starting with the expedition of the frigate Santiago by Juan José Pérez Hernández (see Spanish expeditions to the Pacific Northwest), and the coast of Oregon became a valuable trading route to Asia. In 1778, British captain James Cook also explored the coast. 
French Canadian and métis trappers and missionaries arrived in the eastern part of the state in the late 18th and early 19th centuries, many having travelled as members of Lewis and Clark and the 1811 Astor expeditions. Some stayed permanently, including Étienne Lussier, believed to be the first European farmer in the state of Oregon. The evidence of this French Canadian presence can be found in the numerous names of French origin in that part of the state, including Malheur Lake and the Malheur River, the Grande Ronde and Deschutes rivers, and the city of La Grande.
The Lewis and Clark Expedition travelled through northern Oregon also in search of the Northwest Passage. They built their winter fort in 1805–06 at Fort Clatsop, near the mouth of the Columbia River, staying at the encampment from December until March. 
British explorer David Thompson also conducted overland exploration. In 1811, while working for the North West Company, Thompson became the first European to navigate the entire Columbia River.  Stopping on the way, at the junction of the Snake River, he posted a claim to the region for Great Britain and the North West Company. Upon returning to Montreal, he publicized the abundance of fur-bearing animals in the area. 
Also in 1811, New Yorker John Jacob Astor financed the establishment of Fort Astoria at the mouth of the Columbia River as a western outpost to his Pacific Fur Company;  this was the first permanent European settlement in Oregon.
In the War of 1812, the British gained control of all Pacific Fur Company posts. The Treaty of 1818 established joint British and American occupancy of the region west of the Rocky Mountains to the Pacific Ocean. By the 1820s and 1830s, the Hudson's Bay Company dominated the Pacific Northwest from its Columbia District headquarters at Fort Vancouver (built in 1825 by the district's chief factor, John McLoughlin, across the Columbia from present-day Portland).
In 1841, the expert trapper and entrepreneur Ewing Young died leaving considerable wealth and no apparent heir, and no system to probate his estate. A meeting followed Young's funeral, at which a probate government was proposed.  Doctor Ira Babcock of Jason Lee's Methodist Mission was elected supreme judge.  Babcock chaired two meetings in 1842 at Champoeg, (halfway between Lee's mission and Oregon City), to discuss wolves and other animals of contemporary concern. These meetings were precursors to an all-citizen meeting in 1843, which instituted a provisional government headed by an executive committee made up of David Hill, Alanson Beers, and Joseph Gale.  This government was the first acting public government of the Oregon Country before annexation by the government of the United States. It was succeeded by a Second Executive Committee, made up of Peter G. Stewart, Osborne Russell, and William J. Bailey, and this committee was itself succeeded by George Abernethy, who was the first and only Governor of Oregon under the provisional government.
Also in 1841, Sir George Simpson, governor of the Hudson's Bay Company, reversed the Hudson's Bay Company's long-standing policy of discouraging settlement because it interfered with the lucrative fur trade.  He directed that some 200 Red River Colony settlers be relocated to HBC farms near Fort Vancouver, (the James Sinclair expedition), in an attempt to hold Columbia District.
Starting in 1842–43, the Oregon Trail brought many new American settlers to the Oregon Country. For some time, it seemed that Britain and the United States would go to war for a third time in 75 years (see Oregon boundary dispute), but the border was defined peacefully in 1846 by the Oregon Treaty. The border between the United States and British North America was set at the 49th parallel.  The Oregon Territory was officially organized on August 13, 1848. 
In December 1844, Oregon passed its Black Exclusion Law, which prohibited African Americans from entering the territory while simultaneously prohibiting slavery. Slave owners who brought their slaves with them were given three years before they were forced to free them. Any African Americans in the region after the law was passed were forced to leave, and those who did not comply were arrested and beaten. They received no less than twenty and no more than thirty-nine stripes across their bare back. If they still did not leave, this process could be repeated every six months.  Slavery played a major part in Oregon's history and even influenced its path to statehood. The territory's request for statehood was delayed several times, as members of Congress argued among themselves whether the territory should be admitted as a "free" or "slave" state. Eventually politicians from the south agreed to allow Oregon to enter as a "free" state, in exchange for opening slavery to the southwest United States. 
Oregon was admitted to the Union on February 14, 1859. Founded as a refuge from disputes over slavery, Oregon had a "whites only" clause in its original state Constitution.  At the outbreak of the American Civil War, regular U.S. troops were withdrawn and sent east. Volunteer cavalry recruited in California were sent north to Oregon to keep peace and protect the populace. The First Oregon Cavalry served until June 1865.
Beginning in the 1880s, the growth of railroads expanded the state's lumber, wheat, and other agricultural markets, and the rapid growth of its cities.  Due to the abundance of timber and waterway access via the Willamette River, Portland became a major force in the lumber industry of the Pacific Northwest, and quickly became the state's largest city. It would earn the nickname "Stumptown",  and would later become recognized as one of the most dangerous port cities in the United States due to racketeering and illegal activities at the turn of the 20th century.  In 1902, Oregon introduced direct legislation by the state's citizens through initiatives and referenda, known as the Oregon System. 
On May 5, 1945, six civilians were killed by a Japanese balloon bomb that exploded on Gearhart Mountain near Bly.   They remained the only people on American soil whose deaths were attributed to an enemy balloon bomb explosion during World War II. The bombing site is now located in the Mitchell Recreation Area.
Industrial expansion began in earnest following the 1933–37 construction of the Bonneville Dam on the Columbia River. Hydroelectric power, food, and lumber provided by Oregon helped fuel the development of the West, although the periodic fluctuations in the U.S. building industry have hurt the state's economy on multiple occasions. Portland in particular experienced a population boom between 1900 and 1930, tripling in size; the arrival of World War II also provided the northwest region of the state with an industrial boom, where Liberty ships and aircraft carriers were constructed. 
In 1994, Oregon became the first U.S. state to legalize physician-assisted suicide through the Oregon Death with Dignity Act. A measure to legalize recreational use of marijuana in Oregon was approved on November 4, 2014, making Oregon only the second state at the time to have legalized gay marriage, physician-assisted suicide, and recreational marijuana. 
Oregon's population is largely concentrated in the Willamette Valley, which stretches from Eugene in the south (home of the University of Oregon) through Corvallis (home of Oregon State University) and Salem (the capital) to Portland (Oregon's largest city). 
Astoria, at the mouth of the Columbia River, was the first permanent English-speaking settlement west of the Rockies in what is now the United States. Oregon City, at the end of the Oregon Trail, was the Oregon Territory's first incorporated city, and was its first capital from 1848 until 1852, when the capital was moved to Salem. Bend, near the geographic center of the state, is one of the ten fastest-growing metropolitan areas in the United States. [ better source needed] In southern Oregon, Medford is a rapidly growing metro area and is home to the Rogue Valley International-Medford Airport, the state's third-busiest airport. To the south, near the California border, are the communities of Ashland and Grants Pass. Eastern Oregon is very sparsely populated, but is home to Hermiston, which with a population of 18,000 is the largest and fastest growing city in the region. 
Largest cities or towns in Oregon
A writer in the Oregon Country book A Pacific Republic, written in 1839, predicted the territory was to become an independent republic. Four years later, in 1843, settlers of the Willamette Valley voted in majority for a republic government.  The Oregon Country functioned in this way until August 13, 1848, when Oregon was annexed by the United States and a territorial government was established. Oregon maintained a territorial government until February 14, 1859, when it was granted statehood. 
- a legislative branch (the bicameral Oregon Legislative Assembly),
- an executive branch which includes an "administrative department" and Oregon's governor serving as chief executive, and
- a judicial branch, headed by the Chief Justice of the Oregon Supreme Court.
Governors in Oregon serve four-year terms and are limited to two consecutive terms, but an unlimited number of total terms. Oregon has no lieutenant governor; in the event that the office of governor is vacated, Article V, Section 8a of the Oregon Constitution specifies that the Secretary of State is first in line for succession.  The other statewide officers are Treasurer, Attorney General, Superintendent, and Labor Commissioner. The biennial Oregon Legislative Assembly consists of a thirty-member Senate and a sixty-member House. The state supreme court has seven elected justices, currently including the only two openly gay state supreme court justices in the nation. They choose one of their own to serve a six-year term as Chief Justice. The debate over whether to move to annual sessions is a long-standing battle in Oregon politics, but the voters have resisted the move from citizen legislators to professional lawmakers. Because Oregon's state budget is written in two-year increments and, there being no sales tax, state revenue is based largely on income taxes, it is often significantly over- or under-budget. Recent legislatures have had to be called into special session repeatedly to address revenue shortfalls resulting from economic downturns, bringing to a head the need for more frequent legislative sessions. Oregon Initiative 71, passed in 2010, mandates the legislature to begin meeting every year, for 160 days in odd-numbered years, and 35 days in even-numbered years.
Oregonians have voted for the Democratic presidential candidate in every election since 1988. In 2004 and 2006, Democrats won control of the state Senate, and then the House. Since the late 1990s, Oregon has been represented by four Democrats and one Republican in the U.S. House of Representatives. Since 2009, the state has had two Democratic U.S. senators, Ron Wyden and Jeff Merkley. Oregon voters have elected Democratic governors in every election since 1986, most recently electing Kate Brown over Republican Bud Pierce in a 2016 special election for a two-year term, and re-electing her for a full four-year term over Republican Knute Buehler in 2018.
The base of Democratic support is largely concentrated in the urban centers of the Willamette Valley. The eastern two-thirds of the state beyond the Cascade Mountains typically votes Republican; in 2000 and 2004, George W. Bush carried every county east of the Cascades. However, the region's sparse population means that the more populous counties in the Willamette Valley usually outweigh the eastern counties in statewide elections.
In the 2002 general election, Oregon voters approved a ballot measure to increase the state minimum wage automatically each year according to inflationary changes, which are measured by the consumer price index (CPI).  In the 2004 general election, Oregon voters passed ballot measures banning same-sex marriage  and restricting land use regulation.  In the 2006 general election, voters restricted the use of eminent domain and extended the state's discount prescription drug coverage. 
Like all U.S. states, Oregon is represented by two senators. Since the 1980 census, Oregon has had five congressional districts. After Oregon was admitted to the Union, it began with a single member in the House of Representatives ( La Fayette Grover, who served in the 35th United States Congress for less than a month). Congressional apportionment increased the size of the delegation following the censuses of 1890, 1910, 1940, and 1980. A detailed list of the past and present Congressional delegations from Oregon is available.
The United States District Court for the District of Oregon hears federal cases in the state. The court has courthouses in Portland, Eugene, Medford, and Pendleton. Also in Portland is the federal bankruptcy court, with a second branch in Eugene.  Oregon (among other western states and territories) is in the 9th Court of Appeals. One of the court's meeting places is at the Pioneer Courthouse in downtown Portland, a National Historic Landmark built in 1869.

Political opinions in Oregon are geographically split by the Cascade Range, with western Oregon being more liberal and Eastern Oregon being conservative.  In a 2008 analysis of the 2004 presidential election, a political analyst found that according to the application of a Likert scale, Oregon boasted both the most liberal Kerry voters and the most conservative Bush voters, making it the most politically polarized state in the country. 
While Republicans typically win more counties by running up huge margins in the east, the Democratic tilt of the more populated west is usually enough to swing the entire state Democratic. In 2008, for instance, Republican Senate incumbent Gordon H. Smith lost his bid for a third term, even though he carried all but eight counties. His Democratic challenger, Jeff Merkley, won Multnomah County by 142,000 votes, more than double the overall margin of victory.
During Oregon's history, it has adopted many electoral reforms proposed during the Progressive Era, through the efforts of William S. U'Ren and his Direct Legislation League. Under his leadership, the state overwhelmingly approved a ballot measure in 1902 that created the initiative and referendum for citizens to introduce or approve proposed laws or amendments to the state constitution directly, making Oregon the first state to adopt such a system. Today, roughly half of U.S. states do so. 
In following years, the primary election to select party candidates was adopted in 1904, and in 1908 the Oregon Constitution was amended to include recall of public officials. More recent amendments include the nation's first doctor-assisted suicide law,  called the Death with Dignity Act (which was challenged, unsuccessfully, in 2005 by the Bush administration in a case heard by the U.S. Supreme Court), legalization of medical cannabis, and among the nation's strongest anti-urban sprawl and pro-environment laws.[ citation needed] More recently, 2004's Measure 37 reflects a backlash against such land-use laws. However, a further ballot measure in 2007, Measure 49, curtailed many of the provisions of 37.
Of the measures placed on the ballot since 1902, the people have passed 99 of the 288 initiatives and 25 of the 61 referendums on the ballot, though not all of them survived challenges in courts (see Pierce v. Society of Sisters, for an example). During the same period, the legislature has referred 363 measures to the people, of which 206 have passed.
Oregon pioneered the American use of postal voting, beginning with experimentation approved by the Oregon Legislative Assembly in 1981 and culminating with a 1998 ballot measure mandating that all counties conduct elections by mail. It remains one of just two states, the other being Washington, where voting by mail is the only method of voting.
In the U.S. Electoral College, Oregon casts seven votes. Oregon has supported Democratic candidates in the last eight elections. Democratic incumbent Barack Obama won the state by a margin of twelve percentage points, with over 54% of the popular vote in 2012. In the 2016 election, Hillary Clinton won Oregon by 11 percentage points. 
As of 2015 [update], Oregon ranks as the 17th highest in median household income at $60,834.  The gross domestic product (GDP) of Oregon in 2013 was $219.6 billion, a 2.7% increase from 2012; Oregon is the 25th wealthiest state by GDP. In 2003, Oregon was 28th in the U.S. by GDP. The state's per capita personal income (PCPI) in 2013 was $39,848, a 1.5% increase from 2012. Oregon ranks 33rd in the U.S. by PCPI, compared to 31st in 2003. The national PCPI in 2013 was $44,765. 
Oregon's unemployment rate was 5.5% in September 2016,  while the U.S. unemployment rate was 5.0% that month.  Oregon has the third largest amount of food stamp users in the nation (21% of the population). 
Oregon's diverse landscapes provide ideal environments for various types of farming. Land in the Willamette Valley owes its fertility to the Missoula Floods, which deposited lake sediment from Glacial Lake Missoula in western Montana onto the valley floor.  In 2016, the Willamette Valley region produced over 100 million pounds (45 kt) of blueberries. 
Oregon is also one of four major world hazelnut growing regions, and produces 95% of the domestic hazelnuts in the United States. While the history of the wine production in Oregon can be traced to before Prohibition, it became a significant industry beginning in the 1970s. In 2005, Oregon ranked third among U.S. states with 303 wineries.  Due to regional similarities in climate and soil, the grapes planted in Oregon are often the same varieties found in the French regions of Alsace and Burgundy. In 2014, 71 wineries opened in the state. The total is currently 676, which represents growth of 12% over 2013. 
In the southern Oregon coast, commercially cultivated cranberries account for about 7 percent of U.S. production, and the cranberry ranks 23rd among Oregon's top 50 agricultural commodities. Cranberry cultivation in Oregon uses about 27,000 acres (110 square kilometers) in southern Coos and northern Curry counties, centered around the coastal city of Bandon. In the northeastern region of the state, particularly around Pendleton, both irrigated and dry land wheat is grown.  Oregon farmers and ranchers also produce cattle, sheep, dairy products, eggs and poultry.
Vast forests have historically made Oregon one of the nation's major timber-producing and logging states, but forest fires (such as the Tillamook Burn), over-harvesting, and lawsuits over the proper management of the extensive federal forest holdings have reduced the timber produced. Between 1989 and 2011, the amount of timber harvested from federal lands in Oregon dropped about 90%, although harvest levels on private land have remained relatively constant. 
Even the shift in recent years towards finished goods such as paper and building materials has not slowed the decline of the timber industry in the state. The effects of this decline have included Weyerhaeuser's acquisition of Portland-based Willamette Industries in January 2002, the relocation of Louisiana-Pacific's corporate headquarters from Portland to Nashville, and the decline of former lumber company towns such as Gilchrist. Despite these changes, Oregon still leads the United States in softwood lumber production; in 2011, 4,134 million board feet (9,760,000 m3) was produced in Oregon, compared with 3,685 million board feet (8,700,000 m3) in Washington, 1,914 million board feet (4,520,000 m3) in Georgia, and 1,708 million board feet (4,030,000 m3) in Mississippi.  The slowing of the timber and lumber industry has caused high unemployment rates in rural areas. 
Oregon has one of the largest salmon-fishing industries in the world, although ocean fisheries have reduced the river fisheries in recent years.  Because of the abundance of waterways in the state, it is also a major producer of hydroelectric energy. 
Tourism is also a strong industry in the state. Much of this is centered on the state's natural features; Oregon's mountains, forests, waterfalls, rivers, beaches and lakes, including Crater Lake National Park, Multnomah Falls, the Painted Hills, the Deschutes River, and the Oregon Caves National Monument and Preserve. Mount Hood, and Mount Bachelor also draw visitors year round for skiing and snow activities. 
Portland is home to the Oregon Museum of Science and Industry, the Portland Art Museum, and the Oregon Zoo, which is the oldest zoo west of the Mississippi river.  The International Rose Test Garden is another prominent attraction in the city. Portland has also been named the best city in the world for street food by several publications, including the U.S. News & World Report and CNN.   Oregon is home to many breweries, and Portland has the largest number of breweries of any city in the world. 
The state's coastal region produces significant tourism as well.  The Oregon Coast Aquarium comprises 23 acres (9.3 ha) along Yaquina Bay in Newport, and was also home to Keiko the orca whale.  It has been noted as one of the top ten aquariums in North America.  Fort Clatsop in Warrenton features a replica of Lewis and Clark's encampment at the mouth of the Columbia River in 1805. The Sea Lion Caves in Florence are the largest system of sea caverns in the United States, and also attract many visitors. 
In Southern Oregon, the Oregon Shakespeare Festival, held in Ashland, is also a tourist draw, as is the Oregon Vortex and the Wolf Creek Inn State Heritage Site, a historic inn where Jack London wrote his 1913 novel Valley of the Moon. 
Oregon has also historically been a popular region for film shoots due to its diverse landscapes, as well as its proximity to Hollywood (see List of films shot in Oregon).  Movies filmed in Oregon include: Animal House, Free Willy, The General, The Goonies, Kindergarten Cop, One Flew Over the Cuckoo's Nest, and Stand By Me. Oregon native Matt Groening, creator of The Simpsons, has incorporated many references from his hometown of Portland into the TV series.  Additionally, several television shows have been filmed throughout the state including Portlandia, Grimm, Bates Motel, and Leverage.  The Oregon Film Museum is located in the old Clatsop County Jail in Astoria.
High technology industries located in Silicon Forest have been a major employer since the 1970s. Tektronix was the largest private employer in Oregon until the late 1980s. Intel's creation and expansion of several facilities in eastern Washington County continued the growth that Tektronix had started. Intel, the state's largest for-profit private employer,   operates four large facilities, with Ronler Acres, Jones Farm and Hawthorn Farm all located in Hillsboro. 
The spinoffs and startups that were produced by these two companies led to the establishment in that area of the so-called Silicon Forest. The recession and dot-com bust of 2001 hit the region hard; many high technology employers reduced the number of their employees or went out of business. Open Source Development Labs made news in 2004 when they hired Linus Torvalds, developer of the Linux kernel. In 2010, biotechnology giant Genentech opened a $400 million facility in Hillsboro to expand its production capabilities.  Oregon is home to several large datacenters that take advantage of cheap power and a climate conducive to reducing cooling costs. Google operates a large datacenter in The Dalles, and Facebook built a large datacenter near Prineville in 2010. Amazon opened a datacenter near Boardman in 2011, and a fulfillment center in Troutdale in 2018.

Oregon is also the home of large corporations in other industries. The world headquarters of Nike are located near Beaverton. Medford is home to Harry and David, which sells gift items under several brands. Medford is also home to the national headquarters of Lithia Motors. Portland is home to one of the West's largest trade book publishing houses, Graphic Arts Center Publishing. Oregon is also home to Mentor Graphics Corporation, a world leader in electronic design automation located in Wilsonville and employs roughly 4,500 people worldwide.
Adidas Corporations American Headquarters is located in Portland and employs roughly 900 full-time workers at its Portland campus.  Nike, located in Beaverton, employs roughly 5,000 full-time employees at its 200-acre (81 ha) campus. Nike's Beaverton campus is continuously ranked as a top employer in the Portland area-along with competitor Adidas.  Intel Corporation employs 18,600 in Oregon  with the majority of these employees located at the company's Hillsboro campus located about 30 minutes west of Portland. Intel has been a top employer in Oregon since 1974. 
The U.S. Federal Government and Providence Health systems are respective contenders for top employers in Oregon with roughly 12,000 federal workers and 14,000 Providence Health workers.
In 2015, a total of seven companies headquartered in Oregon landed in the Fortune 1000: Nike, at 106; Precision Castparts Corp. at 302; Lithia Motors at 482; StanCorp Financial Group at 804; Schnitzer Steel Industries at 853; The Greenbrier Companies at 948; and Columbia Sportswear at 982. 
Oregon is one of only five states that have no sales tax.  Oregon voters have been resolute in their opposition to a sales tax, voting proposals down each of the nine times they have been presented.  The last vote, for 1993's Measure 1, was defeated by a 75–25% margin. 
The state also has a minimum corporate tax of only $150 a year,  amounting to 5.6% of the General Fund in the 2005–7 biennium; data about which businesses pay the minimum is not available to the public. [ better source needed] As a result, the state relies on property and income taxes for its revenue. Oregon has the fifth highest personal income tax in the nation. According to the U.S. Census Bureau, Oregon ranked 41st out of the 50 states in taxes per capita in 2005 with an average amount paid of 1,791.45. 
The City of Portland imposes an Arts Education and Access Income Tax on residents over 18 – a flat tax of $35 collected from individuals earning $1,000 or more per year and residing in a household with an annual income exceeding the federal poverty level. The tax funds Portland school teachers, and art focused non-profit organizations in Portland. 
Oregon is one of six states with a revenue limit.  The " kicker law" stipulates that when income tax collections exceed state economists' estimates by 2% or more, any excess must be returned to taxpayers.  Since the enactment of the law in 1979, refunds have been issued for seven of the eleven biennia.  In 2000, Ballot Measure 86 converted the "kicker" law from statute to the Oregon Constitution, and changed some of its provisions.
Federal payments to county governments that were granted to replace timber revenue when logging in National Forests was restricted in the 1990s, have been under threat of suspension for several years. This issue dominates the future revenue of rural counties, which have come to rely on the payments in providing essential services. 
55% of state revenues are spent on public education, 23% on human services (child protective services, Medicaid, and senior services), 17% on public safety, and 5% on other services. 
For health insurance, as of 2018 Cambia Health Solutions has the highest market share at 21%, followed by Providence Health.  In the Portland region, Kaiser Permanente leads.  Providence and Kaiser are vertically integrated delivery systems which operate hospitals and offer insurance plans.  Aside from Providence and Kaiser, hospital systems which are primarily Oregon-based include Legacy Health mostly covering Portland, Samaritan Health Services with five hospitals in various areas across the state, and Tuality Healthcare in the western Portland metropolitan area. In Southern Oregon, Asante runs several hospitals, including Rogue Regional Medical Center. Some hospitals are operated by multi-state organizations such as PeaceHealth and CommonSpirit Health. Some hospitals such Salem Hospital operate independently of larger systems.
Oregon Health & Science University is a Portland-based medical school which operates two hospitals and clinics.
The Oregon Health Plan is the state's Medicaid managed care plan, and it is known for innovations.  The Portland area is a mature managed care and two-thirds of Medicare enrollees are in Medicare Advantage plans.

Oregon has frequently been cited by statistical agencies for having a smaller percentage of religious communities than other U.S. states.   According to a 2009 Gallup poll, Oregon was paired with Vermont as the two "least religious" states in the United States. 
In the same 2009 Gallup poll, 69% of Oregonians identified themselves as being Christian.  The largest Christian denominations in Oregon by number of adherents in 2010 were the Roman Catholic Church with 398,738; The Church of Jesus Christ of Latter-day Saints with 147,965; and the Assemblies of God with 45,492.  Oregon also contains the largest community of Russian Old Believers to be found in the United States.  The Northwest Tibetan Cultural Association is headquartered in Portland. There are an estimated 6,000 to 10,000 Muslims in Oregon, most of whom live in and around Portland. 
Most of the remainder of the population had no religious affiliation; the 2008 American Religious Identification Survey (ARIS) placed Oregon as tied with Nevada in fifth place of U.S. states having the highest percentage of residents identifying themselves as "non-religious", at 24 percent.   Secular organizations include the Center for Inquiry (CFI), the Humanists of Greater Portland (HGP), and the United States Atheists (USA).
During much of the 1990s, a group of conservative Christians formed the Oregon Citizens Alliance, and unsuccessfully tried to pass legislation to prevent "gay sensitivity training" in public schools and legal benefits for homosexual couples.

Projections from the U.S. Census Bureau show Oregon's population increasing to 4,833,918 by 2030, an increase of 41.3% compared to the state's population of 3,421,399 in 2000.  The state's own projections forecast a total population of 5,425,408 in 2040. 
In 2016, the largest school districts in the state were:  Portland Public Schools, comprising 47,323 students; Salem-Keizer School District, comprising 40,565 students; Beaverton School District, comprising 39,625 students; Hillsboro School District, comprising 21,118 students; and North Clackamas School District, comprising 17,053 students.
Especially since the 1990 passage of Measure 5, which set limits on property tax levels, Oregon has struggled to fund higher education. Since then, Oregon has cut its higher education budget and now ranks 46th in the country in state spending per student. However, 2007 legislation funded the university system far beyond the governor's requested budget though still capping tuition increases at 3% per year.  Oregon supports a total of seven public universities and one affiliate. It is home to three public research universities: The University of Oregon (UO) in Eugene and Oregon State University (OSU) in Corvallis, both classified as research universities with very high research activity, and Portland State University which is classified as a research university with high research activity. 
UO is the state's highest nationally-ranked and most selective  public university by U.S. News & World Report and Forbes.  OSU is the state's only land-grant university, has the state's largest enrollment for fall 2014,  and is the state's highest ranking university according to Academic Ranking of World Universities, Washington Monthly, and QS World University Rankings.  OSU receives more annual funding for research than all other public higher education institutions in Oregon combined.  The state's urban Portland State University has Oregon's second largest enrollment.
The state has three regional universities: Western Oregon University in Monmouth, Southern Oregon University in Ashland, and Eastern Oregon University in La Grande. The Oregon Institute of Technology has its campus in Klamath Falls. The quasi-public Oregon Health & Science University (OHSU) includes medical, dental, and nursing schools, and graduate programs in biomedical sciences in Portland and a science and engineering school in Hillsboro. The state also supports 17 community colleges.
Oregon is home to a wide variety of private colleges, the majority of which are located in the Portland area. The University of Portland and Marylhurst University are both Catholic universities located in or near Portland, affiliated with the Congregation of Holy Cross, and the Sisters of the Holy Names of Jesus and Mary, respectively. Reed College, a rigorous liberal arts college in Portland, was ranked by Forbes as the 52nd best college in the country in 2015. 
Other private institutions in Portland include Concordia University; Lewis & Clark College; Multnomah University; Portland Bible College; Warner Pacific College; Cascade College; the National University of Natural Medicine; and Western Seminary, a theological graduate school. Pacific University is in the Portland suburb of Forest Grove. There are also private colleges further south in the Willamette Valley. McMinnville is home to Linfield College, while nearby Newberg is home to George Fox University. Salem is home to two private schools: Willamette University (the state's oldest, established during the provisional period) and Corban University. Also located near Salem is Mount Angel Seminary, one of America's largest Roman Catholic seminaries. The state's second medical school, the College of Osteopathic Medicine of the Pacific, Northwest, is located in Lebanon. Eugene is home to three private colleges: Northwest Christian University, New Hope Christian College, and Gutenberg College.
Until 2011, the only major professional sports team in Oregon was the Portland Trail Blazers of the National Basketball Association. From the 1970s to the 1990s, the Blazers were one of the most successful teams in the NBA in terms of both win-loss record and attendance.  In the early 21st century, the team's popularity declined due to personnel and financial issues, but revived after the departure of controversial players and the acquisition of new players such as Brandon Roy and LaMarcus Aldridge.   The Blazers play in the Moda Center in Portland's Lloyd District, which also is home to the Portland Winterhawks of the junior Western Hockey League. 
The Portland Timbers play at Providence Park, just west of downtown Portland. The Timbers have a strong following, with the team regularly selling out its games.  The Timbers repurposed the formerly multi-use stadium into a soccer-specific stadium in fall 2010, increasing the seating in the process.  The Timbers operate Portland Thorns FC, a women's soccer team that has played in the National Women's Soccer League since the league's first season in 2013. The Thorns, who also play at Providence Park, have won two league championships, in the inaugural 2013 season and also in 2017, and have been by far the NWSL's attendance leader in each of the league's seasons.
Eugene, Salem and Hillsboro have minor-league baseball teams: the Eugene Emeralds, the Salem-Keizer Volcanoes, and the Hillsboro Hops all play in the Single-A Northwest League.  Portland has had minor-league baseball teams in the past, including the Portland Beavers and Portland Rockies, who played most recently at Providence Park when it was known as PGE Park.
The Oregon State Beavers and the University of Oregon Ducks football teams of the Pac-12 Conference meet annually in the Civil War. Both schools have had recent success in other sports as well: Oregon State won back-to-back college baseball championships in 2006 and 2007,  winning a third in 2018;  and the University of Oregon won back-to-back NCAA men's cross country championships in 2007 and 2008.
