List of endangered languages in Bangladesh
According to Bangladesh Bureau of Statistics data from 2011, the country has 27 "small anthropological groups" consisting of 17,84,000 people in total. Ethnologists in Bangladesh and indigenous leaders claim that 48 indigenous communities, a total of 5 million people, are present in Bangladesh. They host 4 language families with 30 ethno-languages. 12-18 of them are endangered at varying degrees. International Mother Language Institute (IMLI) in Dhaka, a government institute, launched a project to reservation and mobilization of 37 languages (including Bengali, the dominant language of Bangladesh). Only 4 of the target languages have their own scripts — Chakma, Marma, Mru, and Meithei. Some other indigenous communities, especially the 2 lakh people living in Rajshahi, use a language called "Sadri" adopting alphabets from Hindi, Bangla, Urdu and other languages. It is used in the Sylhet tea garden area by Telegu, Santhali, Nepali and Rai communities as a lingua franca.
