Districts of Bihar & One District One Product

In 30 of Bihar's 38 districts the district and its headquarters town share the same name — Patna district, Patna town; Gaya district, Gaya town. Only 8 districts break this rule, and those 8 are among the most reliably asked facts in the whole Bihar GK paper. Learn only these eight; everything else follows the default.

Superlatives are the cheapest marks in Bihar GK because there are only a dozen of them and they almost never change. All population, density and literacy figures below are from Census 2011 — the last completed census, and therefore the one BPSC uses.

Bihar is landlocked. Its only international neighbour is Nepal in the north, and three Indian states surround it: Uttar Pradesh in the west, Jharkhand in the south, West Bengal in the east. The border-district lists are pure memory work, and BPSC asks them almost every cycle.

1. West Champaran — westernmost of the Nepal-border districts; Valmiki National Park runs along the frontier.
2. East Champaran — HQ Motihari; Raxaul here is a major Indo-Nepal land crossing.
3. Sitamarhi — Bairgania/Sonbarsa sector; the Bagmati enters Bihar near here.
4. Madhubani — Jainagar crossing; the heart of Mithila.
5. Supaul — the Kosi Barrage at Bhimnagar sits on this border.
6. Araria — Seemanchal; Jogbani is the crossing point.
7. Kishanganj — the only district touching Nepal AND West Bengal; Bihar's wettest district.

This is the core of the chapter. Each row gives you four things: the headquarters, the division, the district's signature product (its ODOP under the PMFME scheme, where identified), and one fact BPSC actually asks. Do not try to memorise all 38 at once. Cover one division per sitting; revise the whole table on Sundays.

Bihar's villages are full of tiny food businesses — a makhana popping unit, a litchi pulping shed, a sattu chakki. Almost all are unregistered, so they cannot get bank credit, cannot print a label, cannot sell outside the district. ODOP is the government's answer: pick one product per district, build the whole support chain around it, and formalise the micro units clustered there.

• The parent scheme is PMFME — Pradhan Mantri Formalisation of Micro Food Processing Enterprises, run by the Ministry of Food Processing Industries (MoFPI), launched on 29 June 2020 as part of Atmanirbhar Bharat Abhiyan.
• It is a centrally sponsored scheme with a 60:40 Centre–State funding pattern, an outlay of about ₹10,000 crore over five years (2020-21 to 2024-25), targeting about 2 lakh micro enterprises.
• Credit-linked capital subsidy of 35% of eligible project cost, capped at ₹10 lakh per unit, for individual micro enterprises.
• Seed capital of ₹40,000 per SHG member for working capital and small tools; grants for FPOs, SHGs and co-operatives for common infrastructure.
• The ODOP approach is the delivery method: because a district's units all make the same product, they can share a common processing facility, cold chain, lab, packaging and brand — a genuine cluster. ODOP has been approved for 713 districts across 35 States/UTs.
• Bihar's biggest ODOP story is makhana (foxnut): Darbhanga, Madhubani, Saharsa, Katihar, Araria and Supaul all carry makhana, and Bihar alone accounts for roughly 85% of India's makhana production — India in turn produces about 80% of the world's makhana.

Thirty-eight districts will not stick as a flat list. They stick when each district is hooked to something you already picture — a river, a division, or a product. Use all three hooks; whichever fires first in the exam hall wins you the mark.

• Hook 1 — by river. Gandak: West & East Champaran, Gopalganj, Muzaffarpur, Saran (joins the Ganga at Sonepur). Bagmati: Sitamarhi, Sheohar, Muzaffarpur. Kosi ("Sorrow of Bihar"): Supaul, Saharsa, Madhepura, Khagaria, Araria, Katihar. Son: Rohtas, Aurangabad, Arwal, Bhojpur, Patna. Falgu/Punpun: Gaya, Jehanabad. Mahananda: Kishanganj, Purnia, Katihar.
• Hook 2 — by division, in one breath. Patna = PN-BB-RK (Patna, Nalanda, Bhojpur, Buxar, Rohtas, Kaimur). Tirhut = the two Champarans + Sitamarhi, Sheohar, Muzaffarpur, Vaishali. Saran = Saran, Siwan, Gopalganj (the three "S/G" of the west). Darbhanga = Darbhanga, Madhubani, Samastipur (Mithila three). Kosi = Saharsa, Supaul, Madhepura (the flood three). Purnia = Purnia, Katihar, Araria, Kishanganj (Seemanchal four). Bhagalpur = Bhagalpur, Banka (the only pair). Munger = Munger, Begusarai, Khagaria, Jamui, Lakhisarai, Sheikhpura. Magadh = Gaya, Nawada, Aurangabad, Jehanabad, Arwal.
• Hook 3 — by signature product. Makhana belt (Mithila + Seemanchal): Darbhanga, Madhubani, Saharsa, Supaul, Araria, Katihar. Litchi belt (Tirhut): Muzaffarpur, East Champaran, Sitamarhi. Rice/poha belt (south-west + Munger): Rohtas, Kaimur, Munger; add Katarni rice for Banka. Sweets & pulses belt (Shahabad–Magadh): Bhojpur, Buxar, Jehanabad, Arwal, and Patna's bakery. Vegetable belt: Nalanda (potato), Saran & Lakhisarai (tomato), Sheikhpura (onion), Begusarai (chilli), Samastipur (turmeric). Fruit belt of the east: Kishanganj (pineapple), Khagaria & Sheohar (banana), Madhepura (mango), Bhagalpur (Jardalu mango), Gopalganj (papaya).
