Elections and representation
ECI publishes Assembly reports for 1978, 1980, 1984, 1990, 1995, 1999, 2004, 2009, 2014, 2019 and 2024. The present Assembly has 60 seats and the State has two Lok Sabha constituencies. The 2024 Assembly poll was held on 19 April and counted on 2 June.
People, economy and development
GSDP/NSDP must state current or constant prices, base year and advance/provisional/revised status. Calendar overlap with a Chief Minister does not prove causation.
| Census | Population | Boundary and interpretation note |
|---|---|---|
| 2001 | 1,097,968 | Reported on the State boundary and district structure used by Census 2001. |
| 2011 | 1,383,727 | Latest completed decennial Census total; later district creation does not alter the State total but breaks district-level comparability. |
2011 social baseline
Census 2011 recorded 713,912 males and 669,815 females, a sex ratio of 938 females per 1,000 males, and literacy of 65.38%.
Official SDP series
The Directorate publishes 2011–12 to 2023–24 advance-estimate tables with GSDP, NSDP, sector shares and current/constant prices. Numeric rows will be admitted only after the PDF table units and estimate labels are machine-checked.
Comparison rule
Census-year geography and population projections are not interchangeable. Economic tables must retain their base year, price basis and revision status.
Forests, wildlife and protected areas
79.63% of the State's geographical area in the State department's ISFR 2021 summary.
11.90% of geographical area, as reported by the competent State department.
The department also records three tiger reserves, two elephant reserves, nine community reserves and one biosphere reserve.
| Class | Official inventory and area (km²) |
|---|---|
| National parks | Namdapha 1,985.24; Mouling 483.00 |
| Wildlife sanctuaries | Pakke 861.95; Kamlang 783.00; Eaglenest 217.00; Mehao 281.50; Dibang 4,149.00; Daying Ering Memorial 190.00; Kane 31.00; Yordi Rabe Supse 397.00; Itanagar 140.30; Tale 337.00; Sessa Orchid 100.00; Ringba-Roba 49.20; Kamala 77.61 |
| Elephant reserves | Kameng 1,892.00; Southern Arunachal 1,957.50 |

Public finance and accountability
CAG State Finances, year ended 31 March 2023
Audit observation—not an allegation of personal guilt: CAG calculated that classification and transfer issues overstated the reported 2022–23 revenue surplus by ₹382.28 crore and the fiscal deficit by ₹386.42 crore. Against the reported ₹6,370.47 crore revenue surplus, the adjusted figure in the report was ₹5,988.19 crore.
CAG compliance audit, transactions tested in 2022–23
Audit scope: the 2025 report examined selected transactions across social, economic, general and revenue sectors, including construction-worker welfare cess, tourism infrastructure and PMGSY. It records expenditure of ₹26,268.80 crore against a ₹32,965.08 crore budget provision in those sectors, with savings of ₹6,696.28 crore. These are audit findings and budget outcomes, not criminal findings.
Labels remain distinct: audit observation, allegation, inquiry, investigation, charge, trial, conviction, acquittal, closure and appeal. An audit paragraph, complaint or FIR is not proof of guilt.
