Gabiley district may be small but it's densely populated since it's a farming region.
Land wise you guys are the largest clan in Toghdeer but not the majority. From the picture you posted, it looks like the red is around 40 %. In Waqooyi Galbeed you only partially settle in one of the three districts (Hargeisa) where the Habar Awal are still the largest clan. In Sanaag, Ceel Afweyne is a shared district with HJ and you guys form a majority in Ceerigabo, but Badhan is 100 % Warsangeli. So at most you guys got half of Sanaag, 40 % of Toghdeer, and maybe 20 % of Waqooyi Galbeed.
