KEY:

1 Where it is indicated 'Yes', a City population is exactly the same as a Metropolitan Area population. If it’s not indicated 'Yes', then those figures are for a Greater Metropolitan Area that includes at least one city/town and adjoining population centres. For example, Baghdad Greater Metropolitan Area is considered the 27th most populous metropolitan area in the World with 11,786,212 residents, while Baghdad City is considered the 67th most populous metropolitan area in the World because only 5,402,486 live within the 'city limits'.
2 "Africa: most populous metropolitan areas" World Gazetteer - All statistics © Stefan Helders, www.world-gazetteer.com. Stefan Helders has been independently collating data relating to population statistics since 1998 on what is now known as the World Gazetteer website. According to Helders... "If possible, official data sources are used. In many cases however no official figures are available. In that case, secondary sources such as year books, encyclopediae, atlases etc. are used. I have also received data from other stats lovers". Along with another useful population statistics website called CityPopulation.de, Stefan Helders/World Gazetteer provides some of the most accurate and up-to-date analysis of population levels in the World's countries, cities and metropolitan areas.
