Did you not read the end of his post ? <| sep |> The link doesn ' t seem to be working for mewas it removed ? <| sep |> wallonia had more inhabitants because they had more jobs , then the antwerp port became a think and since then , most jobs were in FlandersI will argue in the sense of terrain . at least partly . See there are dense regions in Wallonia , the main cities West to east of Charleroi , Namur and Lige . All those cities are linked in the sillon sambre et Meuse and are through that connected with canal to the sea and the Rhine during the industrial revolution it was a very important metallurgic region , but the developpement was limited to that area as it had all the necessary elements coal and transportation infrastructure . But further south there is no coal , the terrain is less flat and the forest more dense so it ' s no wonder that it was a bit forgotten .
