Somali clans

The demographics of Somalia encompass the demographic features of Somalia's inhabitants, including ethnicity, languages, population density, education level, health, economic status, religious affiliations and other aspects of the population.

Somalis constitute the largest ethnic group in Somalia, at approximately 85% of the nation's inhabitants. They are organized into clan groupings, which are important social units; clan membership plays a central part in Somali culture and politics. Clans are patrilineal and are typically divided into sub-clans, sometimes with many sub-divisions. Through the xeer system (customary law), the advanced clan structure has served governmental roles in many rural Somali communities.

Somali society is traditionally ethnically endogamous. So to extend ties of alliance, marriage is often to another ethnic Somali from a different clan. Thus, for example, a recent study observed that in 89 marriages contracted by men of the Dhulbahante clan, 55 (62%) were with women of Dhulbahante sub-clans other than those of their husbands; 30 (33.7%) were with women of surrounding clans of other clan families (Isaaq, 28; Hawiye, 3); and 3 (4.3%) were with women of other clans of the Darod clan family (Majerteen 2, Ogaden 1).

Certain clans are traditionally classed as noble clans, referring to their nomadic lifestyle in contrast to the sedentary Sab who are either agropastoralists or artisanal castes. The two noble clans are Darod, [[Dir (clan)|Dir]. Of these, the Dir are regarded as descended from Irir Samaale, the likely source of the ethnonym Somali. The Darod have separate agnatic (paternal) traditions of descent through Abdirahman bin Isma'il al-Jabarti (Sheikh Darod). Sheikh Darod is, in turn, asserted to have married a woman from the Dir, thus establishing matrilateral ties with the Samaale main stem. Although often recognized as a sub-clan of the Dir, the Isaaq clan claims paternal descent from one Shaykh Ishaq ibn Ahmad al-Hashimi (Sheikh Isaaq). "Sab" is the term used to refer to minor Somali clans in contrast to "Samaale". Both Samaale and Sab are the children of their father "Hiil" whose is the common ancestor all Somali clans.
