Nepal, officially the Federal Democratic Republic of Nepal, is a landlocked country in South Asia. With a population of about 27 million, it has an area of 147,181 square km, making it the 41st most populous and 93rd largest nation in the world. It is bordered by India in the southwest and by China in the northeast. Interestingly, Nepal is unique in the United Nations by virtue of two idiosyncrasies. First, it has the only non-rectangular flag, and second it is the only country which measures its annual economic progress not by GDP growth, but by overall happiness of its citizens.
