Demographics of Bangladesh

Bangladesh is the eighth-most populated country in the world with almost 2.2% of the world's population. As per the 2022 Census of Bangladesh, the country's population is 165,158,616.

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 98% 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 2.0, globally considered to be a 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.

Population growth rate

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.

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 kilometer, and 10th overall, when small countries and city-states are included.

Ethnic group

The vast majority (about 98%) 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 people, Garo, Biharis, Oraons, Mundas.

Biharis are Urdu and other parts of northern India during the 1947 partition. They are concentrated in the Dhaka and Rangpur areas and number some 300,000. In the 1971 independence war many of them sided with Pakistan, as they stood to lose their positions in the upper levels of society.Ethnic and Linguistic Diversity

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. Refugees International has called them a "neglected and stateless" people as they are denied citizenship by the governments of Bangladesh and Pakistan. 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.

Bangladesh's tribal population was enumerated at 897,828 in the 1981 census. 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. 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.

There are small communities of Meitei people in the Sylhet district, which is close to the Meitei homeland across the border in Manipur, India.

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. 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. Since 2017, there are approximately 1.1 million Rohingya refugees living in Bangladesh.

In Bangladesh it represents about 83% of maternal lineages.Mait Metspalu et al., ''Most of the extant mtDNA boundaries in South and Southwest Asia were likely shaped during the initial settlement of Eurasia by anatomically modern humans''.
