Bihar: the political economy of demographic weight without an industrial base

The standing government: the November 2025 verdict

Bihar did not vote in the 2026 round of state elections; its standing government was returned in November 2025. Polling for the 243-seat Vidhan Sabha was held on 6 and 11 November 2025 and the National Democratic Alliance won 202 of the 243 seats — the BJP taking 89 and the JD(U) 85 — against 35 for the opposition Mahagathbandhan, within which the RJD fell to 25 seats, its lowest since 2010. Turnout was 67.25%, roughly ten points above the previous assembly election, and the eighteenth Vidhan Sabha was constituted on 20 November 2025. We carry the seat and vote figures at reference tier: they are consistently reported and reflected in the Bihar dossier’s timeline, but this brief has not read them off the Election Commission’s own results portal.

The composition matters more than the headline. The alliance that governs is a coalition of the BJP and the JD(U), and although the BJP returned the larger bloc of seats, the office of Chief Minister is held by the JD(U) — the same arrangement, with the partner roles by seat count reversed, that has run the state across most of the last two decades. The verdict also holds the state government and the Union government in the same political alignment, which changes the day-to-day texture of Centre–state dealings without dissolving the structural seams set out below. Governments in Bihar have alternated between an RJD-led and a JD(U)-led pole since the RJD’s long incumbency ended in 2005; the durable object here is the state and its position in the federation, not any incumbent.

Political economy: demographic weight without an industrial base

Bihar’s weight in the Union is electoral before it is economic, and the gap between the two is the whole story. At the 2011 Census it held about 10.41 crore people, some 8.6% of India, and it sends 40 members to the Lok Sabha and 16 to the Rajya Sabha — one of the largest state blocs in Parliament. It was also the most rural of the large states, 88.7% rural in 2011. That demographic mass gives it a pull on national policy — on reservation, on caste enumeration, on rural programmes — out of all proportion to what it produces.

What it produces is comparatively little per head. The state’s own Bihar Economic Survey (published by the Finance Department) puts per-capita net state domestic product at 2011-12 constant prices near Rs 36,000 — on the order of a third of the all-India average, the lowest of any major state; Bihar has for years sat at or near the bottom of the Union’s per-capita income table. The NITI Aayog summary for the state records it as carrying among the highest multidimensional poverty burdens in the country, and the state’s own 2022-23 caste survey found roughly a third of families in severe economic distress (reported at around a third of households earning up to Rs 6,000 a month — a figure we carry as reported and do not independently vouch for). We tier these figures honestly: the economic-survey and caste-survey numbers are the state’s own instruments, read as reported rather than lifted line-by-line from the source PDFs.

The structural cause is the 2000 bifurcation. The Bihar Reorganisation Act moved the Chota Nagpur mineral belt and the Dhanbad–Bokaro–Jamshedpur industrial corridor into the new state of Jharkhand and left the population behind, so the state that remained carries most of the people and little of the resource base. What Bihar’s economy now rests on is agriculture on the fertile Gangetic plain — it is a leading producer of vegetables, maize, litchi and makhana (fox nut) — together with a remittance flow from labour that migrates out. The state is the country’s largest source of out-migrant workers, and studies such as the ODI work on migration and remittances in Bihar document how central remitted income is to rural household budgets; the precise share of GSDP that remittances represent is estimated variously and we do not fix a single number to it. The short characterisation is that Bihar exports labour and imports fiscal transfers, and its politics is organised around both.

Fiscal position: the transfer-and-borrow structure

The finances follow directly from the output gap. The 2025-26 budget put GSDP at Rs 10.97 lakh crore and planned expenditure excluding debt repayment at Rs 2,94,075 crore against receipts excluding borrowings of Rs 2,61,357 crore, with the shortfall financed by net borrowings of Rs 32,918 crore, per the independent PRS budget analysis. The budget targeted a fiscal deficit of 3% of GSDP after a revised 9.2% figure in 2024-25 — a spike PRS attributes to accounting for prior liabilities rather than a change in the underlying stance, but a large number on its face nonetheless. A state on one of the Union’s lowest own-revenue bases is correspondingly dependent on Union tax devolution and grants, which is why the Finance Commission cycle matters more here than in richer states: the 16th Finance Commission’s field team visited Bihar as part of the exercise that sets the devolution formula for the coming award period. The recurring feature is that Bihar’s fiscal room is set less by what it raises than by what the Centre transfers — the condition that drives the fault lines below.

Centre–state fault lines specific to Bihar

Below the election result sit the seams in Bihar’s position in the Republic that outlast any government, and the change of alignment in 2025 resolves none of them.

• Special Category Status and the package that replaced it. Bihar has pressed a standing claim for Special Category Status — the enhanced-transfer designation that raises the Union’s share of centrally sponsored schemes and opens concessional finance — arguing from its low per-capita income and its post-2000 resource loss. The Centre denied the claim again in 2024, telling Parliament that no case was made out and noting that the 15th Finance Commission had effectively closed the category. In its place the Union Budget of July 2024 announced a project package for the state — reported at around Rs 26,000 crore for road corridors, Rs 11,500 crore for Kosi-linked flood control and irrigation, a 2,400 MW power plant at Pirpainti, and new airports and medical colleges (DD News, flood-control allocation). The pattern is settled in form and recurring in practice: the special-status demand is refused at the level of principle and partly answered at the level of discretionary project money, and it returns at every Union budget and every Finance Commission.

• Caste enumeration and reservation off a state survey. Bihar used its own legislative room to conduct a caste-based survey in 2022-23 and then, in November 2023, raised total reservation to 65% (EBC to 25%, OBC to 18%, with SC at 20% and ST at 2%) — 75% counting the 10% EWS quota — past the Supreme Court’s Indra Sawhney 50% ceiling. The state sought Ninth Schedule protection from the Union to insulate the law from judicial review; it was not granted, and the Patna High Court struck down the enhanced quotas in June 2024 while leaving the survey itself standing (Reservation in India). The unresolved question — how far a state may legislate reservation off its own enumeration, and whether the Union shields such a law — is a Centre–state and state–judiciary seam at once, and Bihar is the leading test case for it.

• The revised electoral rolls (SIR). Bihar was the proving ground for the Election Commission’s Special Intensive Revision of electoral rolls. The first SIR ran here from June to September 2025, cutting the roll from 7.89 crore to 7.42 crore — about 47 lakh deletions, near 6% of the electorate — months before the November assembly election, and was contested throughout the campaign. The Supreme Court upheld the exercise on 27 May 2026 as consistent with the Representation of the People Act and within the Commission’s constitutional duty, and the revision was extended nationwide from 27 October 2025 (Special Intensive Revision). A federal-institution exercise thus began in Bihar and became a national template; the dispute over whether it altered outcomes is live in other states (see the national SIR brief and the West Bengal brief).

• The Kosi, the embankments and the Nepal seam. Bihar’s floods are the clearest place where the state’s fate is set outside its own jurisdiction. The Kosi and its sister rivers (Gandak, Bagmati, Mahananda) rise in Nepal, and their flows — and the barrages that release them — are governed by India–Nepal arrangements that are Union, not state, business. In late September 2024 the Kosi flood was the worst in decades: about 6.61 lakh cusecs were released from the Birpur barrage after heavy rain in the Nepal catchment, and embankments breached at multiple points across North Bihar, displacing thousands (2024 Koshi flood); a comparable flood-like situation recurred in 2025. Siltation of a river whose bed rises year on year, and a barrage regime that depends on cross-border coordination, mean the state carries the human cost of a hydrology it does not control — which is the standing rationale behind both the special-status claim and the Union’s Kosi-Mechi and flood-control allocations.

• Prohibition as a state instrument. Bihar has enforced statewide prohibition since April 2016 — a ban on the manufacture, sale, storage and consumption of alcohol, re-enacted in stricter form after the Patna High Court struck the first version and the Supreme Court stayed that ruling. It is an example of the state using its List II room hard, and it carries a fiscal edge: the state forgoes the excise revenue that liquor sales provide to almost every other state, deepening the reliance on transfers described above.

Contested vs settled, as of 28 July 2026

Settled (reported and not seriously disputed): that an NDA coalition governs on 202 of 243 seats after the November 2025 election, with the Chief Minister’s office held by the JD(U); that Bihar carries roughly 8.6% of India’s population and 40 Lok Sabha seats on the lowest per-capita income of any major state; that the 2000 bifurcation removed the mineral and industrial base; that the Centre denied Special Category Status in 2024 and answered with a project package; that the Patna High Court struck down the 65% reservation law in June 2024; and that the first SIR was run in Bihar in 2025 and upheld by the Supreme Court in 2026.

Contested / unresolved: how far a state may legislate reservation off its own caste enumeration, and whether the Union extends Ninth Schedule protection — the question the struck-down 2023 law left open. Unsettled on our own record: the exact per-capita and poverty figures (carried as reported from the state’s economic and caste surveys, not read off the source documents), the precise share of GSDP that out-migrant remittances represent (estimated variously in the literature), and the seat and vote totals for the 2025 election (carried at reference tier, not read off the ECI portal).

Who owns this topic (and why we are here)

A search today for “Bihar economy”, “Bihar special category status” or “Bihar election result” surfaces the primary layer — the state finance department’s economic survey, PRS budget analyses, News on AIR and DD News, the Chief Electoral Officer’s portal — alongside live news copy and the exam-prep and encyclopaedic-mirror ecosystem (Drishti-IAS, Vision-IAS, Wikipedia mirrors) that ranks for state-politics questions. What none of them maintains is a single, dated, provenance-tiered state-of-play that holds the political economy, the standing verdict, the fiscal structure and the specific Centre–state seams — special-category status, caste-survey reservation, the revised rolls, the Kosi — in one frame and keeps them current. That is the gap this brief fills, anchored to the structured Bihar dossier and cross-linked to the Election Commission dossier, the national SIR brief and the caste-and-reservation brief. We out-structure the explainer layer on freshness and on the one thing it consistently drops: which figure came from whom, and at what tier.
