The number of Bangladeshis living in India has come down by 800,000 since 2000 and now stands at 3.1 million, a UN report said. In 2000, there were 3.9 million migrants from Bangladesh living in India, according to the 2017 International Migration Report released here on Monday. It said that the number of migrants from all countries living in India now was 5.2 million, a fall of 1.22 million from 2000. The definition of international migrants used in the report is broad and takes into account anyone living in a country different from their own and includes refugees and economic migrants, both those immigrating officially and those who do so "irregularly," said Bela Hovy, the chief of the Migration Section of the UN Department of Economic and Social Affairs (UNDESA).
