new age is here.............
Bangladesh (i /ˈbɑːŋɡlədɛʃ/ or i /bæŋɡləˈdɛʃ/; Bengali: বাংলাদেশ), officially the People's Republic of Bangladesh (Bangla: গণপ্রজাতন্ত্রী বাংলাদেশ Gônoprojatontri Bangladesh) is a sovereign state located in South Asia. It is bordered by India on all sides except for a small border with Burma (Myanmar) to the far southeast and by the Bay of Bengal to the south. Together with the Indian state of West Bengal, it makes up the ethno-linguistic region of Bengal. The name Bangladesh means "Country of Bengal" in the official Bengali language.

The borders of present-day Bangladesh were established with the partition of Bengal and India in 1947, when the region became East Pakistan, part of the newly formed nation of Pakistan. However, it was separated from the western wing by 1,600 km (994 mi) of Indian territory. Due to political exclusion, ethnic and linguistic discrimination, and economic neglect by the politically-dominant West Pakistan, popular agitation grew against West Pakistan and led to the Bangladesh Liberation War in 1971, which the Bengali people won with the support of India. After independence, the new state endured famines, natural disasters and widespread poverty, as well as political turmoil and military coups. The restoration of democracy in 1991 has been followed by relative calm and economic progress.

Bangladesh is a secular republic and a parliamentary democracy, with an elected parliament called the Jatiyo Sangshad. It is the eighth most populous country and among the most densely populated countries in the world. A high poverty rate prevails, although the United Nations has acclaimed Bangladesh for achieving tremendous progress in human development.[6][7]Geographically, the country straddles the fertile Ganges-Brahmaputra Delta and is subject to annual monsoon floods and cyclones.

The country is listed among the Next Eleven economies and Global Growth Generator countries. It is a founding member of the South Asian Association for Regional Cooperation, the D-8 and BIMSTEC, and a member of the Commonwealth of Nations, the Organisation of the Islamic Conference and the Non-Aligned Movement. However, Bangladesh continues to face a number of major challenges, including widespread political and bureaucratic corruption, economic competition relative to the world, serious overpopulation, widespread poverty, and an increasing danger of hydrologic shocks brought on by ecological vulnerability to climate change.

History Main articles: History of Bangladesh and History of Bengal Somapura Mahavihara in Paharpur, Bangladesh, is the greatest Buddhist Vihara in the Indian Subcontinent, built by Dharmapala of Bengal. Remnants of civilization in the greater Bengal region date back four thousand years,[8] when the region was settled by Dravidian, Tibeto-Burman, and Austro-Asiatic peoples. The exact origin of the word "Bangla" or "Bengal" is not known, though it is believed to be derived from Bang, the Dravidian-speaking tribe that settled in the area around the year 1000 BC.[9]

The kingdom of Gangaridai was formed from at least the 7th century BC, which later united with Bihar under the Magadha, Nanda, Mauryan and Sunga Empires. Bengal was later part of the Gupta Empire and Harsha Empire from the 3rd to the 6th centuries CE. Following its collapse, a dynamic Bengali named Shashanka founded an impressive short-lived kingdom. After a period of anarchy, the bengali Buddhist Pala dynasty ruled the region for four hundred years, followed by a shorter reign of the Hindu Sena dynasty. Medieval European geographers located paradise at the mouth of the Ganges and although this was overhopeful, Bengal was probably the wealthiest part of the subcontinent up until the 16th century. The area's early history featured a succession of Indian empires, internal squabbling, and a tussle between Hinduism and Buddhism for dominance.

Islam was introduced to Bengal in the 12th century by Arab Muslim merchants; Sufi missionaries and subsequent Muslim conquests helped spread Islam throughout the region.[10] Bakhtiar Khilji, a Turkic general, defeated Lakshman Sen of the Sena dynasty and conquered large parts of Bengal in the year 1204. The region was ruled by dynasties of Sultans and land lords Bhuiyan for the next few hundred years. By the 16th century, the Mughal Empire controlled Bengal, and Dhaka became an important provincial centre of Mughal administration.

Sixty Dome Mosque in Mosque city of Bagerhat was built in the 15th century and is the largest historical mosque in Bangladesh, as well as a World Heritage site. European traders arrived late in the 15th century, and their influence grew until the British East India Company gained control of Bengal following the Battle of Plassey in 1757.[11] The bloody rebellion of 1857 – known as the Sepoy Mutiny – resulted in transfer of authority to the crown with a British viceroy running the administration.[12] During colonial rule, famine racked the Indian subcontinent many times, including the Great Bengal famine of 1943 that claimed 3 million lives.[13]

Between 1905 and 1911, an abortive attempt was made to divide the province of Bengal into two zones, with Dhaka being the capital of the eastern zone.[14] When India was partitioned in 1947, Bengal was partitioned along religious lines, with the western part going to India and the eastern part (Muslims majority) joining Pakistan as a province called East Bengal (later renamed East Pakistan), with its capital at Dhaka.[15]

Sheikh Mujibur Rahman (3rd person from right) and Maulana Bhashani (4th person from right) in 1953 In 1950, land reform was accomplished in East Bengal with the abolishment of the feudal zamindari system.[16] Despite the economic and demographic weight of the east, however, Pakistan's government and military were largely dominated by the upper classes from the west. The Bengali Language Movement of 1952 was the first sign of friction between the two wings of Pakistan.[17] Dissatisfaction with the central government over economic and cultural issues continued to rise through the next decade, during which the Awami League emerged as the political voice of the Bengali-speaking population. It agitated for autonomy in the 1960s, and in 1966, its president, Sheikh Mujibur Rahman (Mujib), was jailed; he was released in 1969 after an unprecedented popular uprising. In 1970, a massive cyclone devastated the coast of East Pakistan, killing up to half a million people,[18] and the central government responded poorly. The Bengali population's anger was compounded when Sheikh Mujibur Rahman, whose Awami League won a majority in Parliament in the 1970 elections,[19] was blocked from taking office.

After staging compromise talks with Mujib, President Yahya Khan arrested him in the early hours of 26 March 1971, and launched Operation Searchlight,[20] a sustained military assault on East Pakistan. Yahya's methods were extremely bloody, and the violence of the war resulted in many civilian deaths .[21] Chief targets included intellectuals and Hindus, and about ten million refugees fled to neighbouring India.[22] Estimates of those massacred throughout the war range from three hundred thousand to 3 million.[23]

Before his arrest by the Pakistan Army, Sk. Mujibur Rahman formally declared the independence of Bangladesh, and directed everyone to fight till the last soldier of the Pakistan army was evicted from East Pakistan. Awami League leaders set up a government-in-exile in Calcutta, India. The exile government formally took oath at Mujib Nagar in Kustia district of East Pakistan on 17 April 1971, with Tajuddin Ahmad as the first Prime Minister.

After Mujib declared independence of Bangladesh, Yahyah’s brutal crackdown, including a virtual massacre of the intelligentsia in the universities of Bangladesh, was comparable in method to the war crimes of the Nazis. International public opinion was revolted and a tidal wave of hapless refugees, their number soon reaching 10 million, sought shelter in India.[24]

The Bangladesh Liberation War lasted for nine months. The Bangladesh Forces formed within 11 sectors led by General M.A.G. Osmani consisting of Bengali Regulars, and Mukti Bahini conducted a massive guerilla war against the Pakistan Forces with all out support from the Indian Armed Forces. Jointly, the Mitro Bahini achieved a decisive victory over Pakistan on 16 December 1971, with Indian Armed Forces taking over 90,000 prisoners of war.

After its independence, Bangladesh became a parliamentary democracy, with Mujib as the Prime Minister. In the 1973 parliamentary elections, the Awami League gained an absolute majority. A nationwide famine occurred during 1973 and 1974,[13] and in early 1975, Mujib initiated a one-party socialist rule with his newly formed BAKSAL. On 15 August 1975, Mujib and most of his family members were assassinated by mid-level military officers.[25] A series of bloody coups and counter-coups in the following three months culminated in the ascent to power of General Ziaur Rahman, who reinstated multi-party politics, and founded the Bangladesh Nationalist Party (BNP). Zia's rule ended when he was assassinated by elements of the military in 1981.[25]

Bangladesh's next major ruler was General Hossain Mohammad Ershad, who gained power in a bloodless coup in 1982, and ruled until 1990, when he was forced to resign after a massive revolt of all major political parties and the public, along with pressure from western donors (which was a major shift in international policy after the fall of the Soviet Union). Since then, Bangladesh has reverted to a parliamentary democracy. Zia's widow, Khaleda Zia, led the Bangladesh Nationalist Party to parliamentary victory at the general election in 1991, and became the first female Prime Minister in Bangladeshi history. However, the Awami League, headed by Sheikh Hasina, one of Mujib's surviving daughters, won the next election in 1996. It lost again to the Bangladesh Nationalist Party in 2001.

On 11 January 2007, following widespread political unrest, a caretaker government was appointed to administer the next general election. The country had suffered from extensive corruption,[26] disorder and political violence. The new caretaker government has made it a priority to root out corruption from all levels of government. To this end, many notable politicians and officials, along with large numbers of lesser officials and party members, have been arrested on corruption charges. The caretaker government held what observers described as a largely free and fair election on 29 December 2008.[27] Awami League's Sheikh Hasina won the elections with a landslide victory and took the oath of Prime Minister on 6 January 2009.[28]

Government and politics Main article: Politics of Bangladesh See also: Constitution of Bangladesh Jatiyo Sangshad Bhaban houses the Parliament of Bangladesh and is one of the largest legislative complexes in the world National symbols of Bangladesh Anthem Amar Shonar Bangla Animal Royal Bengal Tiger Bird Oriental Magpie Robin Fish Hilsa Flower White Water Lily Fruit Jack fruit Tree Mango Tree Sport Hadudu Calendar Bengali calendar Bangladesh is a unitary state and parliamentary democracy.[29] Direct elections in which all citizens, aged 18 or over, can vote are held every five years for the unicameral parliament known as Jatiya Sangsad. The parliamentary building is known as the Jatiyo Sangshad Bhaban and was designed by architect Louis Kahn. Currently the parliament has 345 members including 45 reserved seats for women, elected from single-member constituencies. The Prime Minister, as the head of government, forms the cabinet and runs the day-to-day affairs of state. While the Prime Minister is formally appointed by the President, he or she must be an MP who commands the confidence of the majority of parliament. The President is the head of state but mainly a ceremonial post elected by the parliament.[30]

However the President's powers are substantially expanded during the tenure of a caretaker government, which is responsible for the conduct of elections and transfer of power. The officers of the caretaker government must be non-partisan and are given three months to complete their task. This transitional arrangement is an innovation that was pioneered by Bangladesh in its 1991 election and then institutionalized in 1996 through its 13th constitutional amendment.[31]

The Constitution of Bangladesh was drafted in 1972 and has undergone 14 amendments.[31] The highest judicial body is the Supreme Court. Justices are appointed by the President. The judicial and law enforcement institutions are weak.[32] Separation of powers, judicial from executive was finally implemented on the 1st of November, 2007. It is expected that this separation will make the judiciary stronger and impartial. Laws are loosely based on English common law, but family laws such as marriage and inheritance are based on religious scripts, and therefore differ between religious communities.

Major parties in Bangladesh are the Bangladesh Awami League and the Bangladesh Nationalist Party (BNP). BNP is led by Khaleda Zia and has traditionally been allied with Islamist parties like Jamaat-e-Islami Bangladesh and Islami Oikya Jot,[33] while Sheikh Hasina's Awami League aligns with leftist and secularist parties. Hasina and Zia are bitter rivals who have dominated politics for over 15 years; each is related to one of the leaders of the independence movement. Another important player is the Jatiya Party, headed by former military dictator Ershad. The Awami League-BNP rivalry has been bitter and punctuated by protests, violence and murder. Student politics is particularly strong in Bangladesh, a legacy from the liberation movement era. Almost all parties have highly active student wings, and student leaders have been elected to the Parliament.

Two radical terrorist organizations, Jagrata Muslim Janata Bangladesh (JMJB) and Jama'atul Mujahideen Bangladesh (JMB), were banned in February 2005. Several small-scale bomb attacks taking place since 1999 have been blamed on those groups, and dozens of suspected members have been detained in security operations, including the heads of those two parties in 2006. The masterminds were tried and executed. The Bangladesh government won praise from world leaders, including Western leaders, for its strong anti-terrorist stance.

The January 22, 2007 election was postponed indefinitely and emergency law declared on January 11, 2007 as the Army backed caretaker government of Fakhruddin Ahmed aimed to prepare a new voter list and crack down on corruption. They also assisted the interim Government of Bangladesh in a drive against corruption, which resulted in Bangladesh's position in Transparency International's Corruption Perceptions Index changed from the very bottom, where they had been for 3 years in a row, to 147th in just 1 year.[34] A large alliance led by the Bangladesh Awami League won the December 29, 2008 poll, in a landslide victory. They got 230 seats among 300 seats in the parliament.[35]

Foreign policy and military Main articles: Foreign relations of Bangladesh and Military of Bangladesh A Bangladeshi Air Force MiG-29 lands at a BAF Base. BNS Bangabandhu, a Bangladeshi Navy frigate. Bangladesh pursues a moderate foreign policy that places heavy reliance on multinational diplomacy, especially at the United Nations. In 1974 Bangladesh joined both the Commonwealth of Nations and the United Nations and has since been elected to serve two terms on the Security Council in 1978–1979 and 2000–2001. In the 1980s, Bangladesh played a lead role in founding the South Asian Association for Regional Cooperation (SAARC) in order to expand relations with other South Asian states. Since the founding of SAARC 1985, a Bangladeshi has held the post of Secretary General on two occasions.

Bangladesh's most important and complex foreign relationship is with India. This relationship is informed by historical and cultural ties and forms an important part of the domestic political discourse. Bangladesh's relationship with India began on a positive note because of India's assistance in the independence war and reconstruction. Throughout the years, relations between both countries have fluctuated for a number of reasons.

A major source of tension between Bangladesh and India is the Farakka Dam.[36] In 1975, India constructed a dam on the Ganges River 11 miles (18 km) from the Bangladeshi border. Bangladesh alleges that the dam diverts much needed water from Bangladesh and adds a man-made disaster to the country already plagued by natural disasters. The dam also has terrible ecological consequences.[36] On the other hand, India has voiced concerns about anti-Indian separatists and Islamic militants allegedly being harboured across their 2,500-mile (4,000 km) border, as well as the flow of illegal migrants, and is building a fence along most of it.[37] But at the 2007 SAARC meeting both nations pledged to work cooperatively on security, economic and border issues.[38]

The current strength of the army is around 200,000 including reservists,[39] the air force 22,000,[39] and navy 14,950.[40] In addition to traditional defense roles, the military has been called on to provide support to civil authorities for disaster relief and internal security during periods of political unrest. Bangladesh is not currently active in any ongoing war, but it did contribute 2,300 troops to the coalition that fought in Operation Desert Storm in 1991 and Bangladesh is consistently a top contributor to UN peacekeeping forces around the world. As of May 2007, Bangladesh had major deployments in Democratic Republic of Congo, Liberia, Sudan, Timor-Leste and Côte d'Ivoire.[41] Presently Bangladesh is the largest troop contributor country to the UN.[42]

Bangladesh enjoys relatively warm ties with the People's Republic of China which has, particularly in the past decade, increased economic cooperation with the South Asian nation. Between 2006 and 2007, trade between the two nations rose by 28.5% and there have been agreements to grant various Bangladeshi commodities tariff-free access to the Chinese market. Cooperation between the Military of Bangladesh and the People's Liberation Army is also increasing, with joint military agreements signed and Bangladesh procuring Chinese arms which range from small arms to large naval surface combatants such as the Chinese Type 053H1 Missile Frigate.

Divisions, districts and upazilas Main articles: Divisions of Bangladesh, Districts of Bangladesh, and Upazilas of Bangladesh Administrative divisions of Bangladesh. This map shows the highest level unit called a Division. Bangladesh is divided into seven administrative divisions,[43][44] each named after their respective divisional headquarters: Barisal (বরিশাল), Chittagong (চট্টগ্রাম), Dhaka (ঢাকা), Khulna (খুলনা), Rajshahi (রাজশাহী), Sylhet (সিলেট), and Rangpur (রংপুর).

Divisions are subdivided into districts (zila). There are 64 districts in Bangladesh, each further subdivided into upazila (subdistricts) or thana. The area within each police station, except for those in metropolitan areas, is divided into several unions, with each union consisting of multiple villages. In the metropolitan areas, police stations are divided into wards, which are further divided into mahallas. There are no elected officials at the divisional, district or upazila levels, and the administration is composed only of government officials. Direct elections are held for each union (or ward), electing a chairperson and a number of members. In 1997, a parliamentary act was passed to reserve three seats (out of 12) in every union for female candidates.[45]

Dhaka is the capital and largest city of Bangladesh. Other major cities include Chittagong, Khulna, Rajshahi, Sylhet, Barisal, Bogra, Comilla, Mymensingh and Rangpur. These cities have mayoral elections, while other municipalities elect a chairperson. Mayors and chairpersons are elected for a span of five years.

Geography and climate Main article: Geography of Bangladesh Satellite image presenting physical features of Bangladesh Karnaphuli River in Kaptai, Chittagong. Bangladesh lies between latitudes 20° and 27°N, and longitudes 88° and 93°E.

Bangladesh is in the low-lying GangesBrahmaputra River Delta or Ganges Delta. This delta is formed by the confluence of the Ganges (local name Padma or Pôdda), Brahmaputra (Jamuna or Jomuna also known as "Yamuna"), and Meghna rivers and their respective tributaries. The Ganges unites with the Jamuna (main channel of the Brahmaputra) and later joins the Meghna to eventually empty into the Bay of Bengal. The alluvial soil deposited by these rivers has created some of the most fertile plains in the world. Bangladesh has 57 trans-boundary rivers, making water issues politically complicated to resolve – in most cases as the lower riparian state to India.[47] Most parts of Bangladesh are less than 12 m (39.4 ft) above the sea level, and it is believed that about 10% of the land would be flooded if the sea level were to rise by 1 m (3.28 ft).[48]

In south east Bangladesh experiments have been done since the sixties to 'build with nature'. By implementing cross dams, the natural accretion of silt has created new land. With Dutch funding, the Bangladeshi government began to help develop this new land in the late 1970s. The effort has since become a multiagency operation building roads, culverts, embankments, cyclone shelters, toilets and ponds, as well as distributing land to settlers. By fall 2010, the program will have allotted some 27,000 acres (10,927 ha) to 21,000 families.[49]

The highest point in Bangladesh is in Mowdok range at 1,052 m (3,451 ft) in the Chittagong Hill Tracts to the southeast of the country.[50] Cox's Bazar, south of the city of Chittagong, has a beach that stretches uninterrupted over 120 kilometres (75 mi).

Straddling the Tropic of Cancer, Bangladeshi climate is tropical with a mild winter from October to March, a hot, humid summer from March to June. A warm and humid monsoon season lasts from June to October and supplies most of the country's rainfall. Natural calamities, such as floods, tropical cyclones, tornadoes, and tidal bores occur almost every year,[51] combined with the effects of deforestation, soil degradation and erosion. The cyclones of 1970 and 1991 were particularly devastating. A cyclone that struck Bangladesh in 1991 killed some 140,000 people.[52]

In September 1998, Bangladesh saw the most severe flooding in modern world history. As the Brahmaputra, the Ganges and Meghna spilt over and swallowed 300,000 houses, 9,700 kilometres (6,027 mi) of road and 2,700 kilometres (1,678 mi) of embankment 1,000 people were killed and 30 million more were made homeless with 135,000 cattle killed, 50 square kilometres (19.3 sq mi) of land destroyed and 11,000 kilometres (6,835 mi) of roads damaged or destroyed. Two-thirds of the country was underwater. There were several reasons for the severity of the flooding. Firstly, there were unusually high monsoon rains. Secondly, the Himalayas shed off an equally unusually high amount of melt water that year. Thirdly, trees that usually would have intercept rain water had been cut down for firewood or to make space for animals.[53]

Bangladesh is now widely recognized to be one of the countries most vulnerable to climate change. Natural hazards that come from increased rainfall, rising sea levels, and tropical cyclones are expected to increase as climate change, each seriously affecting agriculture, water & food security, human health and shelter.[54] It is believed that in the coming decades the rising sea level alone will create more than 20 million[55] climate refugees.[56] Bangladeshi water is contaminated with arsenic frequently because of the high arsenic contents in the soil. Up to 77 million people are exposed to toxic arsenic from drinking water.[57][58] Bangladesh is among the countries most prone to natural floods, tornados and cyclones.[59][60]

Flora and fauna : Royal Bengal Tiger A major part of the coastline comprises a marshy jungle, the Sundarbans, the largest mangrove forest in the world and home to diverse flora and fauna, including the Royal Bengal Tiger. In 1997, this region was declared endangered.[61] The Magpie Robin is the National Bird of Bangladesh and it is common and known as the Doyel or Doel (Bengali: দোয়েল). It is a widely used symbol in Bangladesh, appearing on currency notes and a landmark in the city of Dhaka is named as the Doyel Chatwar (meaning: Doyel Square).The national flower of the country is water lily, which is known as Shapla. The national fruit is jackfruit (Artocarpus heterophyllus) , which in Bengali is known as Kathal. In late 2010, the Bangladeshi government selected the Mango tree as the national tree.[62]

Economy Main article: Economy of Bangladesh Worker in a paddy field – a common scene throughout Bangladesh. Two thirds of the population works in the agricultural sector. A prepared field for sowing paddy plants. At April 2010, USA - based ratings agency Standard & Poor's (S&P) awarded Bangladesh a BB- for a long term in credit rating which is below India and well over Pakistan and Sri Lanka in South Asia.[63] And, despite continuous domestic and international efforts to improve economic and demographic prospects, Bangladesh remains a developing nation.[64] However, Bangladesh gradually decreased its dependency on foreign grant and loan from 85% (In 1988)[65] to 2% (In 2010) [66] for its annual development budget. Its per capita income in 2010 was US$641 compared to the world average of $8,985.[67] But, if purchasing power parity (PPP) is taken into account, Bangladesh's economy is the 44th largest in the world at US$257 billion according to the IMF.

Jute was once the economic engine of the country. Its share of the world export market peaked in the Second World War and the late 1940s at 80%[68] and even in the early 1970s accounted for 70% of its export earnings. However, polypropylene products began to substitute for jute products worldwide and the jute industry started to decline. Bangladesh grows very significant quantities of rice, tea, potato, mango, onion and mustard. According to FAOSTAT, Bangladesh is one of world's largest producers of:[69] Rice (4th), Potato (11th), Mango (9th), Pineapple (16th), Fruit, Tropical (5th), Onion (16th), Banana (17th), Jute (2nd), Tea (11th).

Although two-thirds of Bangladeshis are farmers, more than three quarters of Bangladesh’s export earnings come from the garment industry,[70] which began attracting foreign investors in the 1980s due to cheap labour and low conversion cost. In 2009-10 fiscal year the industry exported US$ 12.6 billion[71] worth of products where in 2002 the exported amount was US$ 5 billion. Recently Bangladesh has been ranked as the 4th[72] largest clothing exporter by the WTO (The World Trade Organization) .[73] The industry now employs more than 3 million workers, 90% of whom are women.[74] A large part of foreign currency earnings also comes from the remittances sent by expatriates living in other countries.

Jamuna Bridge: one of the longest bridges in the world Obstacles to growth include frequent cyclones and floods, inefficient state-owned enterprises, mismanaged port facilities, a growth in the labour force that has outpaced jobs, inefficient use of energy resources (such as natural gas), insufficient power supplies, slow implementation of economic reforms, political infighting and corruption. According to the World Bank, "among Bangladesh’s most significant obstacles to growth are poor governance and weak public institutions."[75] Despite these hurdles, the country has achieved an average annual growth rate of 5% since 1990, according to the World Bank.

Bangladesh has seen expansion of its middle class (world's Fifty Forth largest, just below of Singapore & Vietnam), and its consumer industry has also grown. In December 2005, four years after its report on the emerging "BRIC" economies (Brazil, Russia, India, and China), Goldman Sachs named Bangladesh one of the "Next Eleven",[76] along with Egypt, Indonesia, Vietnam and seven other countries.

Bangladesh has seen a dramatic increase in foreign direct investment. A number of multinational corporations and local big business houses such as Beximco, Square, Akij Group, Ispahani, Navana Group, Transcom Group, Habib Group, KDS Group, Dragon Group and multinationals such as Unocal Corporation and Chevron, have made major investments, with the natural gas sector being a priority. In December 2005, the Central Bank of Bangladesh projected GDP growth around 6.5%.[77] In order to enhance economic growth, the government set up several export processing zones to attract foreign investment. These are managed by the Bangladesh Export Processing Zone Authority.

One significant contributor to the development of the economy has been the widespread propagation of microcredit by Muhammad Yunus (awarded the Nobel peace prize in 2006) through the Grameen Bank. By the late 1990s, Grameen Bank had 2.3 million members, along with 2.5 million members of other similar organisations.[78]

Demographics Main articles: Demographics of Bangladesh, Education in Bangladesh, and Religion in Bangladesh See also: Bengali people Recent (2007–2010) estimates of Bangladesh's population range from 150 to 164 million and it is the 8th most populous nation in the world. In 1951, the population was 44 million.[79] It is also the most densely populated large country in the world, and it ranks 11th in population density, when very small countries and city-states are included.[80] A striking contrast is offered by Russia which has a slightly smaller population spread over a land area that is 120 times larger than Bangladesh. Bangladesh's population growth was among the highest in the world in the 1960s and 1970s, when the country swelled from 50 to 90 million. With the promotion of birth control in the 1980s, the growth rate has slowed. The population is relatively young, with 60% being 25 or younger and 3% being 63 or older. Life expectancy is 63 years for both males and females.[81]

The overwhelming majority of Bangladeshis are ethnic Bengalis, comprising 98% of the population.[82] The remainder are mostly Biharis and indigenous tribal groups. There is also a small but growing population of Rohingya refugees from Myanmar around Cox's Bazaar, which Bangladesh seeks to repatriate to Myanmar. The indigenous tribal peoples are concentrated in the Chittagong Hill Tracts in the southeast. There are 13 tribal groups located in this region, the largest being the Chakma. The Hill Tracts region has been a source of unrest and separatism since and before the inception of Bangladesh.[83] Outside the Hill Tracts, the largest tribal groups are the Santhals and Garos (Achiks), while smaller groups include the Kaibartta, Meitei, Mundas, Oraons, and Zomi.

Nearly all Bangladeshis speak Bangla as their mother tongue and it is the official language.[84] It is an Indo-Aryan language of Sanskrit origin with its own script. English is used as a second language among the middle and upper classes.[85] English is also widely used in higher education and the legal system. Historically, laws were written in English and translated into Bengali until 1987 when the procedure was reversed.[86] The Bihari population speaks Urdu, which was also the language associated with the government prior to separation from Pakistan.

Health and education levels remain relatively low, although they have improved recently as poverty (31% at 2010[87]) levels have decreased. Most Bangladeshis continue to live on subsistence farming in rural villages. Health problems abound, springing from poor water quality and prevalence of infectious diseases. The water crisis is acute, with widespread bacterial contamination of surface water and arsenic contamination of groundwater.[88] Common diseases include malaria, leptospirosis and dengue. The literacy rate in Bangladesh rose to 53.5% in 2007.[89] There is gender disparity, though, as literacy rates are 50% among men and 31% among women, according to a 2004 UNICEF estimate.[89] Among the most successful literacy programs are the Food for education (FFE) introduced in 1993,[90] and a stipend program for women at the primary and secondary levels.[91]

The main religion practiced in Bangladesh is Islam (89.7%), but a significant percentage of the population adheres to Hinduism (9.2%).[92] The majority of Muslims are Sunni. There is a small Shia and an even smaller Ahmadiyya community. Ethnic Biharis are predominantly Shia Muslims. Sufi influences in the region go back many centuries.[93] Other religious groups include Buddhists (0.7%, mostly Theravada), Christians (0.3%, mostly of the Roman Catholic denomination), and Animists (0.1%). Bangladesh has the fourth largest Muslim population after Indonesia, Pakistan, and India, with over 130 million. Bangladesh was founded as a secular state, but Islam was briefly made the state religion, before returning by decree of the High Court to the principles of its 1972 constitution.[94] The High Court also strengthened its stance against punishments by Islamic edict (fatwa), following complaints of brutal sentences carried out against women by extra-legal village courts.[95]
