This is a list of lists of cities :
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 in its 2018 "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, alongside a population density of at least 2,000 per square kilometre. The terms conurbation, metropolis, and metroplex are also applied to the latter.
A metropolitan area or metro is a region consisting of a densely populated urban agglomeration and its surrounding territories which are sharing industries, commercial areas, transport network, infrastructures and housing. A metropolitan area usually comprises multiple principal cities, jurisdictions and municipalities: neighborhoods, townships, boroughs, cities, towns, exurbs, suburbs, counties, districts and even states and nations in areas like the eurodistricts. As social, economic and political institutions have changed, metropolitan areas have become key economic and political regions.
A conurbation is a region comprising a number of metropolises, cities, large towns, and other urban areas which, through population growth and physical expansion, have merged to form one continuous urban or industrially developed area. In most cases, a conurbation is a polycentric urbanised area in which transportation has developed to link areas. They create a single urban labour market or travel to work area.
The London metropolitan area is the metropolitan area of London, England. It has several definitions, including the London Travel to Work Area, and usually consists of the London urban area, settlements that share London's infrastructure, and places from which it is practicable to commute to work in London. It is also known as the London commuter belt, or Southeast metropolitan area.
The Randstad is a roughly crescent- or arc-shaped conurbation in the Netherlands, that houses almost half the country's population. With a central-western location, it connects and comprises the Netherlands' four biggest cities, their suburbs, and many towns in between, that all grew and merged into each other. Among other things, it includes the Port of Rotterdam, the Port of Amsterdam, and Amsterdam Airport Schiphol. With a population of approximately 8.4 million people it is one of the largest metropolitan regions in Europe,[b] comparable in population size to the Rhine-Ruhr metropolitan region or the San Francisco Bay Area, and covers an area of approximately 11,372 km2 (4,391 sq mi).[a] The Randstad had a gross regional domestic product of €510 billion in 2022, making it the second most productive region in the European Union, only behind the Paris metropolitan area. It encompasses both the Amsterdam metropolitan area and Rotterdam–The Hague metropolitan area. It is part of the larger Blue Banana megalopolis.
An urban area is a human settlement with a high population density and an infrastructure of built environment. This is the core of a metropolitan statistical area in the United States, if it contains a population of more than 50,000.
A primate city is a city that is the largest in its country, province, state, or region, and disproportionately larger than any others in the urban hierarchy. A primate city distribution is a rank-size distribution that has one very large city with many much smaller cities and towns and no intermediate-sized urban centers, creating a statistical king effect.
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."
A metropolis is a large city or conurbation which is a significant economic, political, and cultural area for a country or region, and an important hub for regional or international connections, commerce, and communications.
This is a list of cities in Asia by country.
Earth has a human population of over 8 billion as of 2024, with an overall population density of 50 people per km2. Nearly 60% of the world's population lives in Asia, with almost 2.8 billion in the countries of India and China combined. The percentage shares of China, India and rest of South Asia of the world population have remained at similar levels for the last few thousand years of recorded history. The world's literacy rate has increased dramatically in the last 40 years, from 66.7% in 1979 to 86.3% today. Lower literacy levels are mostly attributable to poverty. Lower literacy rates are found mostly in South Asia and Sub-Saharan Africa.
