This document discusses the Africapolis initiative, which maps Africa's changing urban geography. It notes that Africa's urbanization is driven by diverse processes and the emergence of new urban forms beyond large cities. Africapolis defines urban areas as having a minimum of 10,000 inhabitants within continuously built up areas no more than 200 meters apart. It aims to provide comparative and long-term analysis of African urbanization dynamics through data on emerging agglomerations, the absence of rural exodus, and new drivers of urban transformations.
