Selected figures, with their definitions
| Measure | Value | Reference period |
|---|---|---|
| India: final Census 2011 populationpeople | 1,21,08,54,977 | 2011 Official source |
| India: projected populationpeople | 1,42,59,08,000 | 1 March 2026 Official source |
Final/revised historical count using Census 2011 boundaries; retained without relabelling as current population.
Published as 14,25,908 thousand. Converted to persons; precision remains thousands. Equivalent to 142.5908 crore. This is a projection from the July 2020 report.
Start with the kind of number
A census count describes people enumerated for a particular census. A population projection carries a baseline forward using assumptions about births, deaths and migration. Both can answer useful questions, but their dates and methods do different work. A report published in 2020 can contain a projection for 2026 without providing new observations collected in 2026.
Choose a source and a geographic unit
For the historical baseline, use final Census 2011 totals and the boundaries belonging to that table. For a more recent planning figure, the government’s Population Projections for India and States 2011–2036 provides a consistent published series. Our selected totals refer to 1 March 2026 and come from the July 2020 report. Its state geography separates places that were combined in some Census 2011 tables.
A state, district, municipality and urban agglomeration are different areas. Confirm the unit before comparing totals with the same familiar place name. Also retain the report’s original precision: converting a figure from thousands into people does not turn it into an exact enumeration.
Use the total as a denominator
Population can establish the scale of a service area or provide a denominator for another measure. First match the eligible population, year and territory. A service for children needs the relevant age group; a household product needs a household basis. Record any assumptions when the available evidence does not match your intended audience.
Compare without hiding uncertainty
Keep census observations and projections visibly labelled in tables and charts. A growth calculation needs comparable boundaries and compatible source definitions. Avoid treating a difference between two publishers’ projections as measured population change, and avoid interpolating a daily counter that suggests continuously observed precision.
