Africapolis defines an urban  agglomeration using two criteria, a boundary encompasses an area where thereis a population of 10 000 people or more and where buildings are less than 200 metres apart. The 2015 version of Africapolis is the first time where data for all 54 countries is available, which was then updated in 2020. Africapolis closes one major data gap by integrating smaller cities, i.e., those under 500 000 people.",
