The Kingdom of Bhutan is a small, mountainous, landlocked country in South Asia, located in the eastern Himalayas, bordered by India and China. Bhutan is home to a population of about 740,000 spread over approximately 47,000 square kilometers, roughly the size of Switzerland, with about 70% of its land under forest cover. Much of the population lives in the central highlands, and almost two-thirds are classified as rural inhabitants. The terrain is mostly mountainous, with alpine peaks in the north and some sub-tropical foothills in the south. Per capita gross national income (GNI), one of the highest in South Asia, has consistently risen from $730 in 2000 to $2,070 in 2011.
