District factbook / BU-28
Bihar · LGD 213 · Map source name: Purba Champaran
Estimated population of East Champaran. Rank 2 of 38 in this projection.
1.69% annual pace implied by the model’s 2021–2026 values. This is not measured annual growth.
The source projects 67,19,808 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 50,99,371 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.
