Bangladesh (previously East Pakistan between 1947 and 1971 and East Bengal before 1947) is largely ethnically homogeneous and its name derives from the Bengali ethno-linguistic group which comprises 99% of the population. The Chittagong Hill Tracts, Sylhet, Mymensingh, Barisal and North Bengal regions are home to diverse tribal peoples. There are many dialects of Bengali spoken throughout the region. The dialect spoken by those in Chittagong and Sylhet are particularly distinctive. About (91.04%) of Bangladeshis are Muslims, followed by Hindus (largest-minority) at (7.95%), Buddhists (0.61%) and Christians (0.30%) and others (0.12%) as per 2022 census.

Bangladesh has one of the highest population densities in the world. The total fertility rate (TFR) has been reduced by more than two thirds since Independence. The current TFR in Bangladesh is 1.930 per woman,^[13] globally considered to be below the benchmark for replacement level fertility.

At this TFR and without migration, Bangladesh's population is expected to soon reach a stage where it neither grows nor shrinks, once the top of its age pyramid fills in.^[14]

Population

The April 2023 total population was 169,532,362 which makes Bangladesh the eighth-most populous country in the world.

According to the OECD/World Bank population in Bangladesh increased from 1990 to 2008 with 44 million and 38% growth in population compared to 34% growth in India and 54% growth in Pakistan. The annual population growth 2007–2008 was 1.4% compared to India 1.35%, Pakistan 2.2%, Dem. Rep. of Congo 2.9%, Tanzania 2.9%, Syria 3.5% or Yemen 4.0%. According to the OECD/World Bank population statistics between 1990 and 2008 the world population growth was 27% and 1,423 million persons.^[24]

Population growth rate

A view of Paltan and Segunbagicha areas in Dhaka in 2017

Bangladesh had high rates of population growth in the 1960s and 1970s. Since then however it has seen significant reduction in its total fertility rate. Over a period of three decades it dropped from almost 7 to 0.74 in 2005–2018.^[16]

Urban and rural

The sprawling mega-city of Dhaka has a huge population, but the majority of the people nonetheless still live in villages in rural areas.

Urban population: 37.4% of total population (2019 est.)

Rate of urbanization: 3.13% annual rate of change (2019 est.)

Bangladesh is considered an urban country based on their population density^{[citation needed]}

Population density

Based on United Nations Data 2020 figures for population (164,689,383) and land area (130,170 km²), Bangladesh has the highest population density among large countries, 1265 persons per square kilometre, and 10th overall, when small countries and city-states are included.^[26]

Ethnic group

The vast majority (about 99%) of Bangladeshis are of the Bengali ethno-linguistic group. This group also spans the neighboring Indian province of West Bengal. Minority ethnic groups include Meitei, Tripuri, Marma, Tanchangya, Barua, Khasi, Santhals, Chakma, Rakhine, Garo, Biharis, Oraons, and Mundas.

Biharis are Urdu-speaking, non-Bengalis who emigrated from the state of Bihar and other parts of northern India during the 1947 partition. They are concentrated in the Dhaka and Rangpur areas and number some 300,000.^[34][35] In the 1971 independence war many of them sided with Pakistan, as they stood to lose their positions in the upper levels of society.^[36] Hundreds of thousands went to Pakistan and those that remained were interned in refugee camps. Their population declined from about 1 million in 1971 to 600,000 in the late 1980s.^[36] Refugees International has called them a "neglected and stateless" people as they are denied citizenship by the governments of Bangladesh and Pakistan.^[37] As nearly 40 years has passed, two generations of Biharis have been born in these camps. Biharis were granted Bangladeshi citizenship and voting rights in 2008.^[38]

Bangladesh's tribal population was enumerated at 897,828 in the 1981 census.^[36] These tribes are concentrated in the Chittagong Hill Tracts and around Mymensingh, Sylhet, and Rajshahi. They are of Sino-Tibetan descent and differ markedly in their social customs, religion, language and level of development. They speak Tibeto-Burman languages and most are Buddhist or Hindu.^[36] The four largest tribes are Chakmas, Marmas, Tipperas, Tanchangya, and Mros. Smaller groups include the Santals in Rajshahi and Dinajpur, and Khasis, Garos, and Khajons in Mymensingh and Sylhet regions.^[36]

There are small communities of Meitei people (alias Manipuri people) in the Sylhet district, which is close to the Meitei homeland across the border in Manipur, India.^[39][40]

There is a large population of Rohingya refugees from Myanmar near the border in the southeast. There are 28,000 living in two UN refugee camps in Cox's Bazar as well as some 200,000 "unregistered people of concern" living outside of the camps.^[41] The refugee crisis originated in the early 1990s when the first wave numbering some 250,000 of the predominantly Muslim ethnic group fled persecution from their home in Rakhaine—Myanmar's westernmost state. Bangladesh seeks to repatriate the refugees back to Myanmar.^[42] Since 2017, there are approximately 1.1 million Rohingya refugees living in Bangladesh.
