1.08% annual pace implied by the model’s 2021–2026 values. This is not measured annual growth.
Estimate, source count and method
The source projects 35,64,829 people for 1 March 2026. It uses a district ratio method with Government of India state projection inputs. This is a published estimate, not a new Census enumeration or a live count.
The 2011 Census counted 29,59,918 people here. Literacy, density, rural/urban shares and sex ratio below still refer to 2011; they have not been relabelled 2026.
Annual model pace = ((2026 projection ÷ 2021 projection)^(1/5) − 1) × 100. Displayed lakh values are rounded; calculations use source integers.

Census literacy refers to the population aged seven and above. The total rate is the source’s published rate, not a simple average of male and female rates. Sex ratio comes from the separate Census-labelled DES chart series.
