Tunisia, officially the Tunisian Republic, is the northernmost country in Africa. It is a Maghreb country and is bordered by Algeria to the west, Libya to the southeast, and the Mediterranean Sea to the north and east. Its area is almost 165,000 square kilometres (64,000 sq mi), with an estimated population of just over 10.4 million. Its name is derived from the capital Tunis located in the north-east. Tunisia is the smallest of the nations situated along the Atlas mountain range. The south of the country is composed of the Sahara desert, with much of the remainder consisting of particularly fertile soil and 1,300 kilometres (810 mi) of coastline. Tunisia is an export-oriented country in the process of liberalizing and privatizing an economy that has averaged 5% GDP growth since the early 1990s.
