Urban agglomeration in the context of Greater Piraeus

This is a list of urban areas in the European Union with over 500,000 inhabitants as of 2022. The data comes from Demographia and the United Nations Department of Economic and Social Affairs. Demographia provides figures for urban areas (including conurbations), while the UN DESA figures are a mix agglomerations, cities proper and metropolitan areas. For comparison, Function Urban Area (FUA) population figures by Eurostat are also provided, however, these measure the wider metropolitan areas.

A city proper is the geographical area contained within city limits. The term proper is not exclusive to cities; it can describe the geographical area within the boundaries of any given locality. The United Nations defines the term as "... the single political jurisdiction which contains the historical city centre."

City proper is one of the three basic concepts used to define urban areas and populations. The other two are urban agglomeration, and the metropolitan area. In some countries, city limits that act as the demarcation for the city proper are drawn very wide, in some very narrow. This can be cause for recurring controversy.

East Attica (Greek: Ανατολική Αττική) is one of the regional units of Greece. It is part of the region of Attica. The regional unit covers the eastern part of the urban agglomeration of Athens, and also the rural area to its east.

A eurodistrict is a European administrative entity that contains urban agglomerations which lie across the border between two or more states. A eurodistrict offers a program for cooperation and integration of the towns or communes which it comprises: for example, improving transport links for people who live and work on different sides of the border.

The first Eurodistricts created or currently undergoing creation are:

This is a list of the largest urban agglomerations in Africa. Figures are from the United Nations World Urbanization Prospects report, as well as from citypopulation.de. Figures for administrative areas are also given.

A megacity is a very large city, typically with a population of more than 10 million people. The United Nations Department of Economic and Social Affairs (UN DESA) in its "World Urbanization Prospects" report defines megacities as urban agglomerations with over 10 million inhabitants. A University of Bonn report holds that they are "usually defined as metropolitan areas with a total population of 10 million or more people". Elsewhere in other sources, from five to eight million is considered the minimum threshold, along with a population density of at least 2,000 per square kilometre. The terms conurbation, metropolis, and metroplex are also applied to the latter.

The total number of megacities in the world varies between different sources and their publication dates. The world had 32 according to EU Global Human Settlement Layer (in 2024), 33 according to UN DESA (in 2025), 39 according to the OECD, 42 according to Demographia (in 2025), and 45 according to CityPopulation.de (in 2023). The later two add 13 additional cities that are calculated outside the range otherwise. In total, at most 53 unique places are mentioned as megacities across these sources, although some of these are just agglomerated differently between them. A good percentage of these urban agglomerations are in China and India. The other three-to-five countries with more than one megacity are Brazil, Indonesia, Japan, Pakistan, and the United States. African megacities are present in Angola, Democratic Republic of the Congo, Egypt, Nigeria and South Africa; European megacities are present in France, Germany, Russia, the United Kingdom, and Turkey (also in Asia); megacities can be found in Latin America in the countries of Brazil, Mexico, Colombia, Peru, and Argentina.

Štip (Macedonian: Штип [ʃtip] ) is the largest urban agglomeration in the eastern part of North Macedonia, serving as the economic, industrial, entertainment and educational focal point for the surrounding municipalities.

As of the 2021 census, Štip had a population of about 44,866, making it North Macedonia's sixth most populous city.

Piraeus (/paɪˈriːəs, pɪˈreɪəs/ py-REE-əs, pirr-AY-əs; Greek: Περιφερειακή ενότητα Πειραιώς, romanized: Perifereiakí enótita Peiraiós), also sometimes called Greater Piraeus (as distinct from the City of Piraeus; Ευρύτερος Πειραιάς Evrýteros Peiraiás), is one of the regional units of Greece. It is part of the region of Attica. The regional unit covers the west-central part of the Athens urban area (or agglomeration).

Chile's 2017 census reported a population of 17,574,003 people. Its rate of population growth has been decreasing since 1990, due to a declining birth rate. By 2050 the population is expected to reach approximately 20.2 million people, at which point it is projected to either stagnate or begin declining. About 85% of the country's population lives in urban areas, with 40% living in Greater Santiago alone. The largest agglomerations according to the 2002 census are Greater Santiago with 5.6 million people, Greater Concepción with 861,000 and Greater Valparaíso with 824,000.

Zurich (German: Zürich; Alemannic German: Züri; see below) is the largest city in Switzerland and the capital of the canton of Zurich. It is in north-central Switzerland, at the northwestern tip of Lake Zurich. As of the end of 2024, the municipality has a population of 436,551, while the urban area was home to 1.45 million people (2020), while the Zurich metropolitan area had a total population of 2.1 million (2020). Zurich is a hub for railways, roads, and air traffic. Both Zurich Airport and Zurich's main railway station are the largest and busiest in the country.

Evidence of early, sparse settlements in the area dates back more than 6,400 years, indicating human presence prior to the establishment of the town. Permanently settled for over 2,000 years, Zurich was eventually founded by the Romans, who called it Turicum. During the Middle Ages, Zurich gained the independent and privileged status of imperial immediacy and, in 1519, became a primary centre of the Protestant Reformation in Europe under the leadership of Huldrych Zwingli.

Brisbane (/ˈbrɪzbən/ BRIZ-bən; Turrbal/Yagara: Meanjin, Meaanjin, Maganjin or Magandjin) is the capital and largest city of the state of Queensland and the third-most populous city in Australia, with a population of approximately 2.8 million. Brisbane lies at the centre of South East Queensland and is located roughly in the midpoint of Australia's eastern coastline. It is an urban agglomeration with a population of over 4 million. The central business district is situated within a peninsula of the Brisbane River about 15 km (9 mi) from its mouth at Moreton Bay. Greater Brisbane sprawls over the hilly floodplain of the Brisbane River Valley between Pacific Ocean and the Taylor and D'Aguilar mountain ranges, encompassing several local government areas, most centrally the City of Brisbane, the most populous local government area in Australia. The demonym of Brisbane is Brisbanite or Brisbaner.

The Moreton Bay penal settlement was founded in 1824 at Redcliffe as a place for secondary offenders from the Sydney colony, but in May 1825 moved to North Quay on the banks of the Brisbane River, so named for the Governor of New South Wales Sir Thomas Brisbane. German Lutherans established the first free settlement of Zion Hill at Nundah in 1838, and in 1859 Brisbane was chosen as Queensland's capital when the state separated from New South Wales. During World War II, the Allied command in the South West Pacific was based in the city, along with the headquarters for General Douglas MacArthur of the United States Army.

Southern California (commonly shortened to SoCal) is a geographic and cultural region that generally comprises the southern portion of the U.S. state of California. Its densely populated coastal region includes Greater Los Angeles (the second-most populous urban agglomeration in the United States) and San Diego County (the second-most populous county in California). The region generally contains ten of California's 58 counties: Los Angeles, San Diego, Orange, Riverside, San Bernardino, Kern, Ventura, Santa Barbara, San Luis Obispo, and Imperial counties.

Although geographically smaller than Northern California in land area, Southern California has a higher population, with 23.76 million residents as of the 2020 census. The sparsely populated desert region of California occupies a significant portion of the area: the Colorado Desert, along with the Colorado River, is located on Southern California's eastern border with Arizona, and the Mojave Desert shares a border with Nevada to the northeast. Southern California's southern border with Baja California is part of the Mexico–United States border.

Daegu (Korean: 대구 [tɛ̝.ɡu]), formerly spelled Taegu and officially Daegu Metropolitan City (대구광역시), is a city in southeastern South Korea. It is the third-largest urban agglomeration in South Korea after Seoul and Busan; the fourth-largest metropolitan city in the nation with over 2.3 million residents; and the second-largest city after Busan in the Yeongnam region in southeastern South Korea. Daegu and the surrounding North Gyeongsang Province are often referred to as Daegu-Gyeongbuk, with a total population of over 5 million.

Daegu is located in south-eastern Korea about 80 km (50 mi) from the coast, near the Geumho River and its mainstream, Nakdong River in Gyeongsang Province. The Daegu basin is the central plain of the Yeongnam region. In ancient times, the Daegu area was part of the proto-kingdom Jinhan. Subsequently, Daegu came under the control of the Silla Kingdom, which unified the Korean Peninsula. During the Joseon period, the city was the capital of Gyeongsang Province, one of the traditional eight provinces of the country.

The government of Indonesia defines a metropolitan area as an urban agglomeration where its spatial planning is prioritised due to its highly important influence on the country. The metropolitan areas in Indonesia are managed based on Presidential Regulation (Peraturan Presiden). The national government has established 10 metropolitan areas across the country, anchored by the cities of Jakarta, Surabaya, Bandung, Semarang, Medan, Makassar, Palembang, Denpasar, Banjarmasin, and Manado. Despite having no official metropolitan areas recognised on national level, there are several other cities whose urbanised area exceeds their city limits such as Yogyakarta, Malang, and Cirebon.

This is a list of the 50 largest cities in the Americas by population residing within city limits based on the most recent official census results, estimates, or short-term projections available for all of these cities, which refer to mid-2020 populations. These figures do not reflect the population of the urban agglomeration or metropolitan area which typically do not coincide with the administrative boundaries of the city. For a list of the latter, see List of metropolitan areas in the Americas by population. These figures refer to mid-2020 populations with the following exceptions:

1. Mexican cities, whose figures derive from the 2015 Intercensal Survey conducted by INEGI with a reference date of March 15, 2020;
2. Chilean cities, whose figures derive from the 2017 Census projection by Instituto Nacional de Estadísticas;
3. Venezuelan cities, whose figures originate from the 2015 estimate given by the Instituto Nacional de Estadística, with a reference date of 2016.

The following list sorts all cities (including towns and villages) in the Japanese prefecture of Hyōgo with a population of more than 10,000 according to the 2020 Census. As of October 1, 2020, 41 places fulfill this criterion and are listed here. This list refers only to the population of individual cities, towns and villages within their defined limits, which does not include other municipalities or suburban areas within urban agglomerations.
