Western Sahara is a disputed territory on the northwest coast and in the Maghreb region of North and West Africa, partially controlled by the self-proclaimed Sahrawi Arab Democratic Republic and partially occupied by neighboring Morocco. Its surface area amounts to 266,000 square kilometres (103,000 sq mi). It is one of the most sparsely populated territories in the world, mainly consisting of desert flatlands. The population is estimated at just over 500,000, of which nearly 40% live in Laayoune, the largest city in Western Sahara.
