The city of Erbil in Kurdistan has a radial urban structure centred on an ancient fortress.

A city is a human settlement of a substantial size. The term "city" has different meanings around the world and in some places the settlement can be very small. Even where the term is limited to larger settlements, there is no universally agreed definition of the lower boundary for their size. In a narrower sense, a city can be defined as a permanent and densely populated place with administratively defined boundaries whose members work primarily on non-agricultural tasks. Cities generally have extensive systems for housing, transportation, sanitation, utilities, land use, production of goods, and communication. Their density facilitates interaction between people, government organizations, and businesses, sometimes benefiting different parties in the process, such as improving the efficiency of goods and service distribution.

Historically, city dwellers have been a small proportion of humanity overall, but following two centuries of unprecedented and rapid urbanization, more than half of the world population now lives in cities, which has had profound consequences for global sustainability. Present-day cities usually form the core of larger metropolitan areas and urban areas—creating numerous commuters traveling toward city centres for employment, entertainment, and education. However, in a world of intensifying globalization, all cities are to varying degrees also connected globally beyond these regions. This increased influence means that cities also have significant influences on global issues, such as sustainable development, climate change, and global health. Because of these major influences on global issues, the international community has prioritized investment in sustainable cities through Sustainable Development Goal 11. Due to the efficiency of transportation and the smaller land consumption, dense cities hold the potential to have a smaller ecological footprint per inhabitant than more sparsely populated areas. Therefore, compact cities are often referred to as a crucial element in fighting climate change. However, this concentration can also have some significant harmful effects, such as forming urban heat islands, concentrating pollution, and stressing water supplies and other resources.

View toward Mount Illimani from El Alto

La Paz, officially Nuestra Señora de La Paz (Aymara: Chuqiyapu or Chuqi Yapu), is the seat of government of the Plurinational State of Bolivia. With 755,732 residents as of 2024, La Paz is the third-most populous city in Bolivia. Its metropolitan area, which is formed by La Paz, El Alto, Achocalla, Viacha, and Mecapaca makes up the second most populous urban area in Bolivia, with a population of 2.2 million, after Santa Cruz de la Sierra with a population of 2.3 million. It is also the capital of the La Paz Department.

The city, in west-central Bolivia 68 km (42 mi) southeast of Lake Titicaca, is set in a canyon created by the Choqueyapu River. It is in a bowl-like depression, part of the Amazon basin, surrounded by the high mountains of the Altiplano. Overlooking the city is the triple-peaked Illimani. Its peaks are always snow-covered and can be seen from many parts of the city. At an elevation of roughly 3,650 m (11,975 ft) above sea level, La Paz is the highest capital city in the world. Due to its altitude, La Paz has an unusual subtropical highland climate, with rainy summers and dry winters. (Full article...)

Omaha (/ˈməhɑː/ OH-mə-hah) is the most populous city in the U.S. state of Nebraska and the county seat of Douglas County. It is located in the Midwestern United States along the Missouri River, about 10 mi (15 km) north of the mouth of the Platte River. The nation's 41st-most-populous city, Omaha had a population of 486,051 as of the 2020 United States census. It is the anchor of the eight-county Omaha–Council Bluffs metropolitan area, which extends into Iowa and is the 55th-largest metro area in the United States, with a population of 1,001,010. Furthermore, the greater Omaha–Council Bluffs–Fremont combined statistical area had 1,038,894 residents in 2024.

Omaha's pioneer period began in 1854, when the city was founded by speculators from neighboring Council Bluffs, Iowa. The city was founded along the Missouri River, and a crossing called Lone Tree Ferry earned the city its nickname, the "Gateway to the West". Omaha introduced this new West to the world in 1898, when it played host to the World's Fair, dubbed the Trans-Mississippi Exposition. During the 19th century, Omaha's central location in the United States spurred the city to become an important national transportation hub. Throughout the rest of the 19th century, the transportation and jobbing sectors were important in the city, along with its railroads and breweries. In the 20th century, the Omaha Stockyards, once the world's largest, and its meatpacking plants gained international prominence. (Full article...)

"Keep Portland Weird" on a building in Old Town

"Keep Portland Weird" is a popular slogan that appears on bumper stickers, signs, and public buildings throughout Portland, Oregon and its surrounding metro area. It originated from the "Keep Austin Weird" slogan and was originally intended to promote local businesses, though it has since evolved into an all-encompassing slogan that secondarily promotes individuality, expressionism, local art, as well as atypical lifestyle choices and leisure activities. The slogan frequently inspires articles and debate that attempt to quantify the exact level to which Portland is considered weird, unusual or eccentric. It has been called the unofficial motto of Portland, as well as the informal mantra of the city's residents.

The slogan has also been used for a number of years in the Isle of Portland in Dorset, England. Here a landscape heavily changed through extensive quarrying combined with the social and architectural legacy of a long military presence has created a unique environment which has led to the adoption of the "Weird" tag and "Keep Portland Weird" bumper stickers are frequently seen on local vehicles.
