Bangladesh,[a] officially the People’s Republic of Bangladesh,[b] is a country in South Asia. It is the eighth-most populous country in the world and among the most densely populated with a population of over 171 million within an area of 148,460 square kilometres (57,320 sq mi). Bangladesh shares land borders with India to the north, west, and east, and Myanmar to the southeast. It has a coastline along the Bay of Bengal to its south and is separated from Bhutan and Nepal by the Siliguri Corridor, and from China by the Indian state of Sikkim to its north. Dhaka, the capital and largest city, is the nation’s political, financial, and cultural centre. Chittagong is the second-largest city and the busiest port of the country.
Bangladesh is in South Asia on the Bay of Bengal. It is surrounded almost entirely by neighbouring India, and shares a small border with Myanmar to its southeast, though it lies very close to Nepal, Bhutan, and China. The country is divided into three regions. Most of the country is dominated by the fertile Ganges Delta, the largest river delta in the world.[83] The northwest and central parts of the country are formed by the Madhupur and the Barind plateaus. The northeast and southeast are home to evergreen hill ranges.
