Urban agglomeration in the context of "Urbanization"

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.
