Bangladesh, officially the People's Republic of Bangladesh is the eighth most populous country and ranks among the most densely populated countries in the world. Geographically, most of the country is located on the fertile Ganges-Brahmaputra Delta at the confluence of the Ganges (Padma), Brahmaputra (Jamuna) and Meghna Rivers and their tributaries. It is surrounded by India on all sides except for a small border with Myanmar to the far southeast and by the Bay of Bengal to the south. To the south, Bangladesh is surrounded by a dominantly marshy coastline nearly 710 kilometers ling. Hills rise above the plain only in the Chittagong Hill Tracts in the far southeast and the Sylhet division in the northeast. Straddling the Tropic of Cancer, Bangladesh has a subtropical monsoonal climate characterized by heavy seasonal rainfall, moderately warm temperatures, and high humidity. Natural calamities, such as floods, tropical cyclones, tornadoes, and tidal bores affect the country almost every year. Bangladesh also is affected by major cyclones on average 16 times a decade. Dhaka, the capital of Bangladesh is one of the most populated cities with a population of estimated 7.0 million (including areas under the jurisdiction of the Dhaka city corporation). The population of Dhaka is growing by an estimated 4.2% per year, one of the highest rates amongst Asian cities.
