"Thus, we encounter a scenario of ‘missing Hindu population’ in the successive census periods. The extent of this missing population was about 1.22 million during the period of 1974-1981, and about 1.73 million during the last intercensual period 1981-91. As many as 475 Hindus are ‘disappearing’ every day from the soil of Bangladesh on an average since 1974. How this phenomenon would be interpreted in terms of demography? The relevant parameter is obviously ‘migration’ which provides a clue to the missing link."
