Ethiopia is divided into ten ethnically based and politically autonomous regional states (''kililoch'', singular ''kilil'' ) and two chartered cities (''astedader akababiwoch'', singular ''astedader akababi'' ), the latter being Addis Ababa and Dire Dawa. The ''kililoch'' are subdivided into sixty-eight zones, and then further into 550 ''woredas'' and several special ''woredas''.
