Estimated population of Patna. Rank 1 of 38 in this projection.

1.38% annual pace implied by the model’s 2021–2026 values. This is not measured annual growth.
Estimate, source count and method
The source projects 73,42,209 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 58,38,465 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.

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.

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.
04 / CLIMATE
Rain and warmth. Different records.
Rainfall and temperature have different reference periods and geographic methods. They are shown separately.
Historical station-based district normals, using available records within 1951–2000. The publication’s district geography is not asserted to match the 2021 map. This is not a current rainfall forecast.
Sampling point 25.48374° N, 85.38602° E, chosen on the source polygon. Grid: MERRA-2 native meteorology grid: 0.5° latitude × 0.625° longitude. Seasonal means use equal month weights. Summer model maximum: 47.07 °C. Winter model minimum: 1.11 °C. These extrema are reanalysis model values for the period, not observed station records.
A coarse grid-cell sample, not a district average. We requested 2001–2020 explicitly and checked each response period; the API’s default uses a different period.
05 / PLACES & HERITAGE
Beyond the number.

A courtyard, a young tree, the shadow of its branches on stone. This photograph was taken at Bihar Museum in 2017, two years after its inauguration. The museum tells Bihar's history through objects; the courtyard offers a moment between galleries.
Bapu Tower is a Gandhi-focused memorial and exhibition building in Gardanibagh, Patna. The district description distinguishes its copper-faced circular tower from an adjoining rectangular structure. Its displays and turntable theatre were conceived to present episodes from Gandhi’s life. The source describes the project, rather than providing a dependable current schedule for the exhibitions.
That table totals 70 sites for Bihar. A newer March 2026 reply reports 71 statewide, without a district crosswalk. We keep the dated district figures instead of labelling them current.

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.
