GEOGRAPHY

Bangladesh is a low-lying, riparian country located in South Asia with a largely marshy jungle coastline of 710 kilometers (440 mi.) on the northern littoral of the Bay of Bengal. Formed by a deltaic plain at the confluence of the Ganges (Padma), Brahmaputra (Jamuna), and Meghna Rivers and their tributaries, Bangladesh's alluvial soil is highly fertile but vulnerable to flood and drought. 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.

Urbanization is proceeding rapidly, and it is estimated that only 30% of the population entering the labor force in the future will be absorbed into agriculture, although many will likely find other kinds of work in rural areas. The areas around Dhaka and Comilla are the most densely settled. The Sundarbans, an area of coastal tropical jungle in the southwest and last wild home of the Bengal tiger, and the Chittagong Hill Tracts on the southeastern border with Burma and India, are the least densely populated.

PEOPLE
The area that is now Bangladesh has a rich historical and cultural past, combining Dravidian, Indo-Aryan, Mongol/Mughul, Arab, Persian, Turkic, and west European cultures. Residents of Bangladesh, about 98% of whom are ethnic Bengali and speak Bangla, are called Bangladeshis. Urdu-speaking, non-Bengali Muslims of Indian origin, and various tribal groups, mostly in the Chittagong Hill Tracts, comprise the remainder. Most Bangladeshis (about 88.3%) are Muslims, but Hindus constitute a sizable (10.5%) minority. There also are a small number of Buddhists, Christians, and animists. English is spoken in urban areas and among the educated.

Sufi religious teachers succeeded in converting many Bengalis to Islam, even before the arrival of Muslim armies from the west. About 1200 AD, Muslim invaders established political control over the Bengal region. This political control also encouraged conversion to Islam. Since then, Islam has played a crucial role in the region's history and politics, with a Muslim majority emerging, particularly in the eastern region of Bengal.
