35.65 lakh

UNFPA district projection 1 Mar 2026

Estimated population of Rohtas. Rank 18 of 38 in this projection.

2021 projection33.78 lakh
2026 projection35.65 lakh

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.

The population is a 2011 Census count, not a present-day projection. Literacy is republished to one decimal. Density is the source’s 2011 figure; it is not calculated using the later map.

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.

02 / ECONOMY

Income, in its year.

Bihar DES 2023–24
Gross district domestic product · current prices₹25,298.7 crore

Source value: ₹25,29,874 lakh.

Per-capita income · source label₹73,067

2023–24 · rupees per person

Per-capita income is not GDP per person or a household’s earnings. These are current-price figures for 2023–24. They have not been adjusted for inflation or carried forward to 2026.

A PMFME programme designation. It does not mean this is the district’s only product, largest crop, or a geographical indication.

Rice, wheat and maize are components of the cereals total. Do not add the total to those components. The endpoint’s separate “food grain” field is excluded because its period and definition could not be reconciled.

Son

Natural Earth 1:10m dataset

Names reflect a geometric intersection of two approximate map datasets. This is not a complete river inventory; absence here does not mean absence of rivers. “Ganges”, “Ghäghara” and “Sapt” are the source’s labels.

Approximate mapped area · 2021 source
3,894 km²
East–west envelope span
97 km

Map-derived area is not the official Census area and is not used as the denominator for population density. The span is not a road distance. Geographic methods.

07 / EVIDENCE

Keep the source
with the fact.

This page combines a 2011 demographic snapshot, 2023–24 income, 2024–25 crop output, a 2024 product list and separate historical climate series. It does not describe one common year.

Male/female population counts, workforce and religion are not available in this edition. Rounded sex ratios are not used to reconstruct counts.
