Members of the Ogaden clan primarily live in the central Ogaden plateau of Ethiopia (Somali Region), the North Eastern Province of Kenya, and theJubaland region of Southern Somalia. They also inhabit Somalia's major cities such as Mogadishu and Kismayo.
According to Human Rights Watch, the Ogaden is the largest Darod clan in Ethiopia's Somali Region, and may account for 40 to 50 percent of the Somali population in Ethiopia. The Ogaden clan "constitutes the backbone of the ONLF". In particular, the ONLF operates in areas inhabited by the Reer Adulle sub-clan of the Mohamed Zubeir.
There is no clear agreement on the clan and sub-clan structures and many lineages are omitted. The following listing is taken from the World Bank's Conflict in Somalia: Drivers and Dynamics from 2005 and the United Kingdom's Home Office publication, Somalia Assessment 2001.
