Libya is a large country with a relatively small population, but the population is concentrated very narrowly along the coast. Population density is about 50 persons per km² (130/sq. mi.) in the two northern regions of Tripolitania and Cyrenaica, but falls to less than one person per km² (2.6/sq. mi.) elsewhere.
Tripoli is the de jure capital city and the largest city of Libya. Tripoli, with its metropolitan area, has a population of about 1.1 million people. The city is located in the northwestern part of Libya on the edge of the desert, on a point of rocky land projecting into the Mediterranean and forming a bay.
Libya extends over 1,759,540 square kilometres (679,362 sq mi), making it the 17th largest nation in the world by size. Libya is somewhat smaller than Indonesia in land area, and roughly the size of the US state of Alaska. It is bound to the north by the Mediterranean Sea, the west by Tunisia and Algeria, the southwest by Niger, the south by Chad and Sudan and to the east by Egypt. Libya lies between latitudes 19° and 34°N, and longitudes 9° and 26°E.
