The Press Information Bureau explainer assesses claims that India has around 20 million undocumented Bangladeshi migrants. It argues that official census patterns do not support such a large estimate, and it uses census omission rates, birthplace reporting, and migrant-stock data to test the claim.
What the explainer says
The explainer sets out three possible ways undocumented migrants could appear in census data: they may evade the census entirely, they may be counted but falsely report India as their birthplace, or they may report their birthplace truthfully. It then uses census evidence to examine each possibility.
UPSC may ask how census methodology, post-enumeration surveys, and demographic evidence can be used to evaluate claims on undocumented migration, and what the limits of such official data are.
