Les 32 plus grandes agglomérations du monde : comment l’urbanisation repousse-t-elle ses limites ?

The classification of the largest agglomerations in the world, called megacities, proposed by the UN is supported by countless scientific or non-scientific publications. Yet the statisticians who make these lists do not conceal the existence of serious problems of comparability due to the fact that...
