Addis Ababa is the capital and largest city of Ethiopia. It is the seat of the Ethiopian federal government. According to the 2007 population census, the city has a total population of 2,739,551 inhabitants.
As a chartered city, Addis Ababa has the status of both a city and a state. It is where the African Union is headquartered and where its predecessor the Organisation of African Unity was based. It also hosts the headquarters of the United Nations Economic Commission for Africa, as well as various other continental and international organizations. Addis Ababa is therefore often referred to as "the political capital of Africa" for its historical, diplomatic and political significance for the continent.
