About Portland, OR

Portland ( PORT-lənd) is the most populous city in the U.S. state of Oregon. Located in the Pacific Northwest at the confluence of the Willamette and Columbia rivers, it is the 28th-most populous city in the United States, sixth most populous on the West Coast, and third most populous in the Pacific Northwest (after Seattle and Vancouver, British Columbia) with a population of 652,503 at the 2020 census. The Portland metropolitan area, with over 2.54 million residents, is the 26th-largest metropolitan area in the nation. Almost half of Oregon's population resides within the Portland metro area. It is the county seat of Multnomah County, Oregon's most populous county. The Portland area was shaped by massive ice-age floods. It was inhabited by the Chinookan peoples. European American settlers arrived in the 1840s. Following a coin toss, Portland was named after Portland, Maine, which was itself named after England's Isle of Portland. In the 19th century, Portland became a major port and lumber center and gained a reputation for saloons and crime. The 20th century saw population growth, World War II shipbuilding, Japanese-American internment, organized crime, and a hippie/counterculture movement. Since the 1990s, it has experienced growth in the technology sector and rising housing costs. It saw major George Floyd protests in 2020–2021. Portland is located near volcanic features such as Mount Tabor and is also close to active faults. The city is divided into six addressing sectors and comprises diverse neighborhoods. Portland has a predominantly White population. The city’s economy is driven by technology, athletic and outdoor brands, shipping, and craft industries. Social issues include homelessness and property crime, although recent trends indicate a low violent crime rate. The city prioritizes urban planning, sustainability, and diverse transportation options, while managing growth with an urban growth boundary. Portland also has numerous schools and universities, media outlets, healthcare facilities, and global sister-city connections. The city operates with a mayor–council government system, guided by a mayor and 12 city councilors, as well as Metro, the only directly elected metropolitan planning organization in the United States. Its climate is marked by warm, dry summers and cool, rainy winters. This climate is ideal for growing roses, and Portland has been called the "City of Roses" for more than a century. Portland is known for its vibrant music and performing arts scene, extensive parks including Forest Park, and professional sports teams such as the Trail Blazers, Timbers, and Thorns.
