Megacity Think-Tank Alliance (MeTTA)
A megacity is a very large city, typically with a population of more than 10 million people. Precise definitions vary: the United Nations Department of Economic and Social Affairs in its 2018 "World Urbanization Prospects" report counted urban agglomerations having over 10 million inhabitants. A University of Bonn report held that they are "usually defined as metropolitan areas with a total population of 10 million or more people". Others list cities satisfying criteria of either 5 or 8 million and also having a population density of 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: The world had 33 according to the UN (in 2018), 37 according to ''CityPopulation.de'' (in 2020), and 35 according to ''Demographia'' (in 2020). About half these urban agglomerations are in China and India. The other four countries with more than one megacity are Br ...

Cities generally have extensive systems for housing, transportation, sanitation, utilities, land use, production of goods, and communication. Their density facilitates interaction between people, government organisations and businesses, sometimes benefiting different parties in the process, such as improving 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 g ...
