This has little to do with geographic spread and more to do with your lack of numbers. You just do not have the numbers to have a city as large as Hargeisa or Xamar. We have already established you are a minority 3rd place clan in Somalia after Hawiye and Raxanweyn, you are also an even more insignificant minority in Somaliland coming 3rd after Isaaq and Dir.Darood are spread out. Darood live in most northern Somali land which is Caluula, the most western Somali town which is Tuuli Gulled and most Southern Somali which is Ijaraa, Garissa County. In conclusion; Darood have more land than all other Somalis combine. Darood have a lot small towns
The geographic spread argument is not sound, remember, midgaans are also geographically spread out.
