The facts are simple, UNFPA study is way more recent and way more accurate than an estimate from near 100 years ago, it is also in line with findings of the only study ever conducted by a central government on Somalis. Its astounding that you are attempting to ignore that the Nugaal region which included all 3 Dhulbahante districts from Sool was the least populated region in the union state.
Every study conducted in the last 80 years prove Dhulbahante territory to be very sparsely populated and Dhulbahante were a small minority in Somali Republic just like they are a minority in Somaliland today.
This is not true. Firstly because Sool is not 80% Dhulbahante as you claim. Outside of Las Anod, Cayabo district is the largest in the region. Additionally, a region with only HJ as inhabitants would most certainly have larger population than Sool. What you dont seem to want to understand is that Dhulbahante territory is more sparsely populated than HJ:

As clearly shown in the map, Dhulbahante territory is much more sparsely populated even than adjacent clans like HJ, GX and WS.
Almost no one lives outside of Las Anod in places like Xudun and Taleex according to the population density map.
