List of urban areas by population
of world cities
This is a list of contiguous urban areas of the world ranked according to population. Figures have been taken from two sources: Demographia's "World Urban Areas" study, and from citypopulation.de, created by Thomas Brinkhoff of the Institut für Angewandte Photogrammetrie und Geoinformatik.
Definitions and issues
Demographia defines an urban area (urbanized area agglomeration or urban centre) as a continuously built up land mass of urban development that is within a labor market (i.e. metropolitan area or metropolitan region), without regard for administrative boundaries (i.e. municipality, city or commune). Except in Australia, the authorities use a minimum urban density definition of 400 persons per square kilometer (or the nearly identical 1,000 per square mile in the United States). Demographia uses maps and satellite photographs to estimate continuous urbanization. Demographia also uses small area population data, where available, to match population estimates to urbanized land area. National census authority data are presented in Australia, Canada, France, Norway, Sweden, the United Kingdom and the United States. Census of India urban agglomerations are not used in some cases because the geographical size of constituent units (municipalities) often includes large rural (non-urban) areas.
Sources for population estimates and land area definitions are coded by letter in the Table below, respectively.
- A: National census authority data agglomeration data (land area or population).
- B: Demographia land area estimate based upon map or satellite photograph analysis.
- C: Demographia population estimate from lower order jurisdictions, including reduction for rural areas.
- D: Population estimate based upon the United Nations agglomeration estimate.
- E: Demographia population estimate from national census authority data.
- F: Other Demographia population estimate, such as from unofficial local reports.
- L: Demographia population estimate from local authority data.
- N: Combined urban area using national census authority data.
- W: Population estimate based upon the World Bank Urban Area 2015 estimate.
The estimates are quite different from the list of World's largest urban agglomerations produced by the United Nations that reports inconsistently on urban geographic, despite its reference to agglomerations. This is evident, for example, in Manila, Kuala Lumpur, Jakarta, Seoul and Moscow, where the UN data are for political jurisdictions, rather than urban areas. In other cases, the UN data is for metropolitan area, which are larger than urban areas (such as in Brazil). Finally, the United Nations data is incomplete, excluding some significant urban areas (such as Essen–Düsseldorf in Germany).
Urban areas are confined to a single nation, unless there is freedom of movement (including labor) between the adjacent nations. Currently, this condition is met only between some continental nations of the European Union and Switzerland (e.g. Lille–Kortrijk in both France and Belgium, Aachen–Vaals in both Germany and Netherlands, Saarbrücken–Forbach in both Germany and France, Geneva–Annemasse in both Switzerland and France, and Basel–Lörrach–Saint-Louis in Switzerland, Germany and France). Thus, Detroit–Windsor in both the United States and Canada, and San Diego–Tijuana in both the United States and Mexico are not treated as single urban areas. Moreover, Shenzhen–Hong Kong is treated as separate urban areas, principally because labor movement between the two is limited, with the former within China and the latter a special administrative region of China.
According to the report, there are 875 identified urban areas in the world with 500,000 or more population as of 2013. Demographia released along with the report include a disclaimer that this list of data is compiled on best available information, the vary nature of which is changing rapidly and quality is improving as it becomes available, yet still remains highly variable between nations, and hefty revisions are not unforeseen for the future. Appropriate caution is therefore advised.

- Includes large areas of Tokyo, Kanagawa, Chiba and Saitama prefectures and small areas of Gunma, Tochigi and Ibaraki prefectures.
- Various international sources limit their population estimates to DKI Jakarta itself (the national capital district). However, the urbanization of Jakarta extends into the regencies of Tangerang, Bekasi, Bogor and Karawang and the separate cities of Bekasi, Depok and Bogor. Excludes urban areas of Karawang (650,000; 207 km2) and Serang (525,000; 65 km2).
- Includes Faridabad, Ghaziabad, Noida, Gurgaon and Bahadurgarh. Excludes urban area of Meerut (1,489,000; 104 km2).
- The population is higher than other agglomeration estimates (such as the United Nations and the Philippine Statistics Authority). The continuous urbanization of Manila extends outward into other neighbouring provinces such as Bulacan, Cavite, Laguna, Rizal and Batangas provinces. The Demographia population estimate is a "build-up" of municipality population within the continuously developed area (urban area or agglomeration).
- Includes satellite cities in Gyeonggi Province such as Suwon, Goyang, Seongnam, Yongin, Bucheon and Ansand which are treated as separate urban agglomerations by the United Nations. Excludes urban area of Cheonan (500,000; 57 km2) in Chungcheongnam-do.
- Shanghai, Hangzhou, Nanjing, Suzhou, Wuxi, Ningbo, Changzhou, Shaoxing, and urban area of Zhangjiaggang-Jiangyin within the prefecture-level cities of Suzhou and Wuxi are treated as separate urban areas which constitute the Yangtze River Delta economic zone. Huai'an (1,856,000; 148 km2), Xuzhou (1,246,000; 233 km2), Nantong (1,036,000; 233 km2), Lianyungang (985,000; 155 km2), Zhenjiang (983,000; 168 km2), Yancheng (797,000; 207 km2), Huzhou (690,000; 111 km2), Taizhou (in Jiangsu Province; 300,000; 117 km2) and Suqian (220,000; 36 km2), as well as urban areas of Yangzhou (1,593,000; 233 km2) and Gaoyou (180,000; 39 km2) within the prefecture-level city of Yangzhou, urban areas of Kunshan (1,596,000; 492 km2), Changshu (1,139,000; 285 km2) and Taicang (523,000; 117 km2) within the prefecture-level city of Suzhou, urban areas of Cixi (1,200,000; 298 km2) and Yuyao (650,000; 122 km2) within the sub-provincial city of Ningbo, urban areas of Jiaxing (1,044,000; 259 km2) and Tongxiang (510,000; 52 km2) within the prefecture-level city of Jiaxing, urban areas of Wenling (510,000; 52 km2), Jiaojiang (375,000; 41 km2) and Huangyan (200,000; 34 km2) within the prefectrure-level city of Taizhou (in Zhejiang Province), urban areas of Zhuji (500,000; 117 km2) and Shangyu (400,000; 158 km2) within the prefecture-level city of Shaoxing, urban areas of Yiwu-Dongyang (925,000; 233 km2), Jinhua (520,000; 186 km2), Yongkang (500,000; 223 km2), Dongyang (260,000; 104 km2) and Lanxi (220,000; 34 km2) within the prefecture-level city of Jinhua, and urban area of Fuyang (450,000; 49 km2) within the sub-provincial city of Hangzhou are also excluded.
- Includes Kalyan, and the Panvel urban area. As of 2016, also includes the Census of India urban areas of Bhiwandi, Kalyan, VasaiVirar beginning in 2016.
- Demographia defines urban area of New York as a combination of New York–Newark, Bridgeport–Stamford, New Haven, Trenton, Danbury and Twin Rivers urbanized areas. New York and Philadelphia (same with Philadelphia urbanized area) are treated as separate urban areas. Urban areas of Hartford (925,000; 1,336 km2), Allentown–Bethlehem (665,000; 896 km2), Springfield (621,000; 904 km2), Harrisburg (446,000; 673 km2), Poughkeepsie (427,000; 847 km2), Lancaster (405,000; 642 km2), Reading (284,000; 269 km2), Atlantic City (250,000; 324 km2), York (235,000; 342 km2), Norwich–New London (209,000; 394 km2), Waterbury (195,000; 233 km2) and Pottstown (108,000; 205 km2) are also excluded.

- Hong Kong in the Hong Kong Special Administrative Region and Shenzhen are treated as separate urban areas because of the lack of freedom of labor movement without trade, immigration or customs barriers. Guangzhou–Foshan, Shenzhen, Dongguan and Zhongshan are also treated as separate urban areas which constitute the Pearl River Delta economic zone. While Guangzhou and Foshan are combined into a single urban area because they have become more economically integrated than the other urban areas, other areas in the Pearl River Delta economic region remain classified as separate urban areas. Thus, urban areas of Huizhou (1,387,000; 168 km2), Zhuhai (1,274,000; 246 km2) and Zhaoqing (500,000; 65 km2) as well as urban areas of Jiangmen (920,000; 259 km2) and Taishan (204,000; 44 km2) within the prefecture-level city of Jiangmen, urban area of Lishui (300,000; 44 km2) within the prefecture-level city of Foshan and urban are of Macau (560,000; 21 km2) in the Macau Special Administrative Region are excluded.

Other estimates (such as the United Nations estimate) include only the municipality of Moscow, which includes only part of the urban footprint. Includes Elektrostal–Noginsk within Moscow Oblast, which has been excluded in the 2011 edition.
