What is List of largest cities?
This is a '''list of the largest cities in the world by [[population|number of people]]'''. The number of people in a city can be counted in three ways:<ref>[[UNICEF]]. 2012. [https://www.unicef.org/media/89226/file/The%20State%20of%20the%20World's%20Children%202012.pdf ''The State of the World’s Children 2012: Children in an Urban World'']. New York, UNICEF.</ref> *[[City proper]]: The area that is officially part of the [[city]], according to the government. *[[Urban area]]: An area of built-up land, with many roads, buildings, and [[infrastructure]]. It usually has many people close together, who do not work in [[farming]]. [[Rural]] land is the opposite: it has a small number of people and buildings. In this list, an urban area is an area of urban land that is [[wikt:continuous|continuous]]: it has no spaces in between that are rural. *[[Metropolitan area]]: An urban area, and nearby areas where people frequently travel ([[commuting|commute]]) to the urban area. Some of these areas are [[suburbs]] and some can have a small number of people. This is according to the government, so it can mean different things in different countries. __TOC__ ==List== {{Static row numbers}} {| {{static row numbers table}} |- {{static row numbers header}} ! rowspan=2 | City{{efn|For urban/metropolitan areas that have more than one [[core city]], the number for their city proper should use either the most populous one (e.g. [[Dallas]] for [[Dallas–Fort Worth metroplex]]) or the best-known one (e.g. [[Manila]] for [[Metro Manila]], instead of [[Quezon City]]).}} ! rowspan=2 | Country ! rowspan=2 style=max-width:4em | UN 2018 population estimates{{efn|UN numbers for each cities are varied between city proper, metropolitan area, and urban area.<ref name=UNpopulation>{{Cite web |url=https://population.un.org/wup/Publications/Files/WUP2018-Highlights.pdf |year=2019 |work=United Nations |location=New York |title=World Urbanization Prospects 2018 |access-date=14 April 2020 |archive-date=11 February 2020 |archive-url=https://web.archive
