A general understanding of Somalia's geographic, demographic and culture is important in this analysis. Somalia sits on the Horn of Africa at the Entrance of the Gulf of Aden and the Red Sea. Djibouti to the North, Ethiopia to the West and Kenya to the South provides its borders of approximately 8.5 million people, more than 98 percent are Somali giving it unusual ethnic homogeneity. More than 45 percent of the population are under 15 years of age. About 70 percent of Somali's are nomads who travel with their livestock, herds through Somalia, Kenya and Ethiopia. A lack of definite borders contributes to the unresolved land disputes between Somalia and its neighbors.
