Several recent evolutions have modified the spatial distribution of the Senegalese population, which historically used to be in a few parts of the country: the densification of previously sparsely inhabited territories; the process of urbanisation, which expands to the whole country and is associated to the transformation of rural villages into fullfledged municipalities; the extension of the road network to areas that were previously isolated from urban centers. Despite the fact that the Eastern part of the country has long considered itself forgotten, and that the lower Casamance area remains home to irredentist mouvements partly due to its distance from the country centre, the national territory appears to be caught up by spatial dynamics that only concerned the West until then.
