Kazakhstan is the world's largest landlocked country. It is found in the middle of Central Asia, surrounded by powerful neighbors like China and Russia. However, despite its vast size, the population of Kazakhstan is only 18 million, which gives it one of the world's lowest population densities. The population density of Kazakhstan is around 7 people per square kilometer. A relatively mysterious country to the western world, Kazakhstan is known for its coastline on the Caspian Sea, its stunning steppe, and the mountain ranges that lay around the perimeter of the country.
