Bangladesh is largely ethnically homogeneous. Indeed, its name derives from the Bengali ethno-linguistic group, which comprises 98% of the population. Bengalis, who also predominate in the West Bengal province of India, are one of the most populous ethnic groups in the world. Variations in Bengali culture and language do exist of course. There are many dialects of Bengali spoken throughout the region. The dialect spoken by those in Chittagong and Sylhet are particularly distinctive. In 2009 the population was estimated at 156 million. Religiously, about 90% of Bangladeshis are Muslims and the remainders are mostly Hindus.
Bangladesh became one of the large nation states in 1971when it seceded from Pakistan. Prior to the creation of Pakistan in 1947, modern-day Bangladesh was part of ancient, classical, medieval and colonial India.
Since independence, the government has experienced periods of democratic and military rule. The founding leader of the country and its first president was Sheikh Mujibur Rahman. His daughter Sheikh Hasina Wazed is currently the prime minister, as leader of the Awami League.
Physical features of Bangladesh
Location & size
Bangladesh is situated in southern Asia, on the delta of the 2 largest rivers on the Indian subcontinent—the Ganges and Jamuna (Brahmaputra).
It borders with India in the west, north, and east, with Burma (also known as Myanmar) in the southeast, and with the Bay of Bengal in the south. The country's area is 144,000 square kilometers (55,598 square miles), and it is divided into 6 administrative divisions (Dhaka, Chittagong, Khulna, Barisal, Rajshai and Sylhet) and 4 major municipal corporations (Dhaka, Chittagong, Khulna and Rajshahi). Comparatively, the territory of Bangladesh is slightly greater than the state of New York.
Bangladesh's capital city, Dhaka, is located in the central part of the country. Bangladesh occupies the eastern part of the Bengal region (the western part of the region is occupied by the Indian state of West Bengal), which historically was part of the great civilizations in the northeast of the Indian subcontinent. Climate of Bangladesh
Bangladesh has a tropical monsoon-type climate, with a hot and rainy summer and a dry winter. January is the coolest month with temperatures averaging near 26 deg C (78 d F) and April the warmest with temperatures from 33 to 36 deg C (91 to 96 deg F). The climate is one of the wettest in the world. Most places receive more than 1,525 mm of rain a year, and areas near the hills receive 5,080 mm ). Most rains occur during the monsoon (June-September) and little in winter (November-February).
Bangladesh is subject to devastating cyclones, originating over the Bay of Bengal, in the periods of April to May and September to November. Often accompanied by surging waves, these storms can cause great damage and loss of life. The cyclone of November 1970, in which about 500,000 lives were lost in Bangladesh, was one of the worst natural disasters of the country in the 20th century.
Bangladesh has warm temperatures throughout the year, with relatively little variation from month to month. January tends to be the coolest month and May the warmest. In Dhaka the average January temperature is about 19°C (about 66°F), and the average May temperature is about 29°C (about 84°F).
Surface water inflow and river system of Bangladesh
Surface Water made up of rivers, streams, lakes, beels and ponds. In other words, all waters on the surface of the earth including fresh and salt water, ice and snow. In Bangladesh, rainfall and trans-boundary river flows are the main sources of surface water. Bangladesh has an average annual surface flow of about 1,073 million acre feet (MAF), of which about 870 MAF (93%) are received from India as inflow and rest 203 MAF (7%) as rainfall. This water is enough to cover the entire country to a depth of 9.14m. About 132...
