The largest urban areas in the world by population in 2013 game: http://www.purposegames.com/game/largest-megacities-of-the-world-game The largest urban areas in the world by population in 2013 : largest cities in the world The largest urban areas in the world by population in 2013 : largest cities in the world 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 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.
