Andorra is a small landlocked country in western Europe, located in the eastern Pyrenees mountains and bordered by Spain and France. Once isolated, it is currently a prosperous country mainly because of tourism and its status as a tax haven. The people of Andorra are currently listed as having the highest human life expectancy in the world, at an average of 83 years at birth (2008 est). Andorra is the sixth smallest nation in Europe. Its name is thought to be derived from that of an ancient Basque tribe, the Andosinos, that is believed to have inhabited that region of the Pyrenees thousands of years ago.
