As of 2026. Land acquisition for dams, mining and industry continues, and the cumulative estimate is periodically revised upward as state-level studies are completed.
Since independence India has acquired land on a vast scale for dams, canals, mines, industrial estates and urban expansion under the colonial-era Land Acquisition Act of 1894 and its successors, displacing tens of millions of people. Estimates of the cumulative total range from about 21 million in an Indian government working-group calculation to 40-60 million in the state-by-state reconstruction by the sociologist Walter Fernandes and colleagues; Adivasi (tribal) and Dalit communities are heavily over-represented, holding perhaps a quarter of the displaced despite being under a tenth of the population, and a large share of those displaced were never resettled. The Sardar Sarovar dam on the Narmada became the emblematic case: sustained protest by the Narmada Bachao Andolan led the World Bank to commission the Morse Committee independent review, which in 1992 found resettlement and environmental requirements unmet, and the Bank withdrew from the project in 1993; construction continued with Indian funding and the Supreme Court of India permitted the dam to be raised in judgments from 2000. India replaced the colonial land-acquisition law in 2013 with legislation requiring consent, social impact assessment and resettlement entitlements, whose implementation and subsequent amendment remain contested. Displacement is administrative and compensated in law rather than violent, but the compulsion, the scale and the failure of resettlement are documented by government committees themselves.

The 1951 census counted 361,088,090 people. The 40 million figure for development-induced displacement comes from the work of Walter Fernandes and colleagues at the Indian Social Institute and North Eastern Social Research Centre, compiled state by state from land-acquisition records because no national register of displaced persons exists; other estimates range from about 20 to 60 million, and much of the variation turns on whether people who lost land but not homes are included.
There is no mass death toll; this is displacement by compulsory acquisition rather than violence. Deaths have occurred in police action against protests, including at the Narmada and at anti-acquisition protests elsewhere, and impoverishment following unresettled displacement is documented, but no mortality figures exist.
Indian government committees, the World Commission on Dams and the 1992 Morse independent review documented submergence and demolition of homes ahead of, or without, adequate resettlement.
