Xplaya, Your list of districts are out of accuracy. You have also omitted many districts and towns intentionally.
There are nine Zonal adminstration in that Somali region. Liban zone, the Gode Zone and 7 others. I will get the info if time permits.
Let us come back to Gode zone, which you intentionally ignored.
IImey reer AMaadin , Ogaaden
Kalafo, Bahgeri
Gode, Tolomoge, Ogaden
Dhanan, Reer Ugaas Nuur , Ogaden
Ferfeer , Hawiye
Jigjiga, the Capital, is settled by Geri, Jidwaq only and it is the largest city in the regino. The current president hails from Geri. The Geri has unequivocal history of extending their rule to Dir tribes and Some Oromo. These clans have been paying tribute to Geri since up to recently for fear that Geri will put them to death.
You can read also this quote from a well-trusted source. UNITED Nation, Somalia Study. It states Darood as the largest tribe in Somalia. Also, if you read, "Clanship and Contracts" of I.M Lewis, It refers to Somali population when we were numerically less than today. He estimated Darood to be over a Million and Half out of 3 Million. You can't deny that Source also.

Harrying of the Hawiye
The Hawiye occupy the south central portions of Somalia (see Samaal , ch. 2). The capital of Mogadishu is located in the country of the Abgaal, a Hawiye subclan. In numbers the Hawiye in Somalia are roughly comparable to the Isaaq, OCCUPYING A SECOND DISTANT PLACE to the Daarood clans. Southern Somalia's first prime minister during the UN trusteeship period, Abdullaahi Iise, was a Hawiye; so was the trust territory's first president, Aadan Abdullah Usmaan. The first commander of the Somali army, General Daauud, was also a Hawiye. Although the Hawiye had not held any major office since independence, they had occupied important administrative positions in the bureaucracy and in the top army command."
This map highlights the clan distribution of Kenya,
http://www.ejoka.com/ken-eth.jpgThere are other sources that indicate that Juballand, an area settled by Marehan, Harti, and Ogaden to be 23 % of Somali population. Alone that region.
I have used sources. I expect you to use sources.
My time is limited. Northern Harti alone accopies more lands than All Isaaq put together.
I am giving all of this info to be impartial and show the world the numerical supremacy of Darod Ismail.
