Here is the distribution of Y-DNA haplogroups by province for Belgium based on the current results from the Brabant DNA project. The project having originated in Flanders, with a special emphasis on the old Duchy of Brabant (provinces of Antwerp, Flemish Brabant, Walloon Brabant and Brussels) there are far more Flemish samples than Walloon ones at the moment.
