Definitions and issues 
(For more on definitions, see World's largest cities)
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, 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 resuction 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.
The most reliable population estimates are A and N. Population estimates C are generally reliable. Population estimates D are less reliable, because it is sometimes difficult to determine whether the data is based upon metropolitan area, urban area populations or some other definition. Population estimates E are also less reliable, for generally these estimates are derived by subtracting estimated population for the rural parts of metropolitan areas based upon estimated urban versus rural population differentials. Population estimates coded F and L are the least reliable (e.g. Pyongyang in Democratic People's Republic of Korea (North Korea) and Tunis in Tunisia).
The projected year (2013) population estimate is further calculated from the base year population estimate using population growth rate based upon the United Nations population growth rate with some exceptions.
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 or Pattaya in Thailand).
Urban areas are confined to a single metropolitan area or labor market area. In some cases, urban areas have virtually grown together (e.g. Taiheiyō Belt in Japan, the Pearl River Delta in the People's Republic of China and the Northeast megalopolis in the United States), yet are still considered separate urban areas.
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. It is important to recognize that most of the data are estimated. Appropriate caution is therefore advised.

- The population is higher than other agglomeration estimates (such as the United Nations), tend to be limited to Metro Manila, which is a province level jurisdiction. The continuous urbanization of Manila extends outward into 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).
- The population is lower than other estimates (such as the United Nations), which include metropolitan area population not within the continuously developed urban area.
- 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.

- Excludes urban areas of Toluca (1,747,000; 220 km2) and Cuernavaca (675,000; 171 km2).
- Excludes urban areas of Baoding (1,283,000; 220 km2), Zhangjiakou (1,322,000; 220 km2) and Chengde (108,000; 23 km2).
- 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. Urban area of Guangzhou–Foshan includes Shunde within the prefecture-level city of Foshan, which has been excluded in the 2011 edition. Urban area of Shenzhen includes Huiyang within the prefecture-level city of Huizhou, which has been excluded in the 2010 edition. Urban area of Huizhou includes only Huicheng District. The Demographia estimate for Dongguan is lower than last year, because local estimates previously used were higher than reported in the 2010 census.
- Mumbai and Kalyan are treated as separate urban areas, although the census of India classifies Kalyan within the Mumbai agglomeration. Kalyan is excluded by Demographia because of the lack of continuous urbanization Mumbai. Urban area of Mumbai includes Panvel and Navi Mumbai, but excludes urban area of Vasai–Virar (1,147,000; 91 km2) and Bhiwandi (737,000; 52 km2), which have been included in the 2011 edition. A large part of the municipality of Mumbai is rural, composed of the Sanjay Gandhi National Park and thus not included in the urban area.
- Includes Nara and Himeji. United Nations estimates separate Osaka–Kobe and Kyoto and exclude both Nara and Himeji. Excludes urban area of Ōtsu (775,000; 303 km2) and Wakayama (430,000; 91 km2).
- The population estimate is suspect, due to the lack of readily available data for local areas outside the city jurisdiction (Moscow Oblast). Demographia is indebted to Richard Forstall, who has provided local authority area population data for portions of Moscow Oblast within the Moscow urban areas. 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.
