Location and Distribution of Industrial Centres in India: ISC Class 12 Geography

What Location and Distribution of Industrial Centres is about

Weightage: CISCE publishes no chapter or unit weightage for ISC Geography. Location and Distribution of Industrial Centres is part of 5. Industries (a) of the 2027 syllabus and can be asked anywhere in the 70-mark Paper I (Section A one-mark and map items, Section B 4-mark short answers, Section C 7-mark long answers).Source: CISCE ISC Geography (853) syllabus, examination year 2027; ISC 2027 specimen question paper

Key concepts

Factors of industrial location: physical and economic

1. Raw materials: industries using heavy, bulky or weight-losing raw materials locate near their source to save transport costs (iron and steel near iron ore and coal in Chota Nagpur; sugar mills near cane fields because cane loses sucrose soon after cutting; cement near limestone). Industries using light or pure raw materials (cotton textiles) can locate near markets.
2. Power: early industries clustered near coalfields (Damodar valley); today electricity transmitted through grids allows wider dispersal, though power-hungry industries (aluminium) still seek cheap power.
3. Labour: large supplies of cheap or skilled labour attract industries (textiles in Mumbai and Ahmedabad; IT in Bengaluru).
4. Market: industries producing perishable, fragile or bulky finished goods locate near consumers (bakeries, soft drinks, furniture); large cities attract consumer industries.
5. Transport: railways, highways and ports reduce the cost of assembling raw materials and distributing products; port cities (Mumbai, Kolkata, Chennai, Visakhapatnam) attract industry.
6. Water: needed for cooling, processing and power (steel, textiles, chemicals, paper); hence riverside locations (Hooghly belt, Damodar).
7. Capital and banking: available in big cities.
8. Land: cheap, flat land for factories.
9. Climate: humid climate helped cotton spinning in Mumbai; not very important now.

Worked example

[2] How do raw materials pull certain industries towards particular places? Use an Indian example. (Understand)

Try it first, then show the solutionSolution

1. Industries using heavy, bulky or weight-losing raw materials locate near the source to cut transport costs - 1 mark.
2. Example: iron and steel plants in the Chota Nagpur region near iron ore and coal; sugar mills near cane fields - 1 mark.

Answer: Industries whose raw materials are heavy, bulky or lose weight in processing locate near the source to save transport costs, as iron and steel plants do in the Chota Nagpur region close to iron ore and coal, and sugar mills do near sugarcane fields.

Factors of industrial location: political and historical

1. Government policy: licensing, incentives, subsidies, tax concessions and public sector investment; deliberate location of public sector plants in backward areas (Bhilai, Rourkela, Bokaro); industrial corridors and Special Economic Zones (SEZs); 'Make in India' and production-linked incentives.
2. Industrial inertia: once established, industries tend to stay even after the original advantage has gone, because of existing infrastructure, skilled labour and linkages (Mumbai's cotton mills, Jamshedpur).
3. Agglomeration economies: industries cluster to share infrastructure, suppliers, services and skilled workers (automobile clusters around Chennai, Pune and Gurugram).
4. Political stability and law and order.
5. Historical factors: colonial ports and their hinterlands (Mumbai, Kolkata, Chennai) became the first industrial centres.
6. Banking, insurance and entrepreneurship: availability of finance and business communities.

Types of industry by location tendency:

• Raw-material oriented: iron and steel, sugar, cement, paper.
• Market oriented: consumer goods, food processing, petroleum refining in some cases.
• Footloose: not tied to raw materials or power; can locate almost anywhere with good communication and skilled labour (electronics, software, gems). (The next chapters distinguish key and footloose industries.)

Worked example

[2] Explain industrial inertia with an Indian example. (Understand)

Try it first, then show the solutionSolution

1. Industrial inertia: an industry continues at its original location even after the original advantages have weakened - 1 mark.
2. Example: cotton mills remained in Mumbai, or steel at Jamshedpur, because of established infrastructure, skilled labour and markets - 1 mark.

Answer: Industrial inertia is the tendency of an industry to remain where it began even after the original reasons have weakened, because moving would waste existing factories, skills and links. Mumbai's cotton textile industry continued long after raw cotton could be grown and processed elsewhere.

Distribution of important industrial centres

India's industries are concentrated in a few regions and centres:
1. Mumbai-Pune region (Maharashtra): cotton textiles, engineering, chemicals, petrochemicals, automobiles, pharmaceuticals, IT, film.
2. Hooghly region (West Bengal): jute, engineering, chemicals, paper, around Kolkata and Howrah; Haldia (petrochemicals).
3. Gujarat region (Ahmedabad-Vadodara-Surat-Jamnagar): cotton textiles, petrochemicals and refineries, chemicals, diamonds, pharmaceuticals.
4. Chota Nagpur region (Jharkhand, Odisha, West Bengal, Chhattisgarh): iron and steel (Jamshedpur, Bokaro, Rourkela, Durgapur), heavy engineering, coal-based power.
5. Bengaluru-Chennai-Coimbatore region: electronics, software, aircraft, automobiles, textiles.
6. Gurugram-Delhi-Meerut region: automobiles, electronics, light engineering, agro-processing.
7. Visakhapatnam-Guntur region: steel, shipbuilding, refinery, fertilisers.

Isolated industrial centres also exist: Kanpur, Indore, Nagpur, Bhilai, Kochi, Bhubaneswar, Hyderabad.

General pattern: industries are concentrated around the large port cities (Mumbai, Kolkata, Chennai), the mineral belt of the north-east Peninsula, and the capital region, with growing dispersal along highway corridors.

Worked example

[4] Name four major industrial regions of India and one industry characteristic of each. (Recall)

Try it first, then show the solutionSolution

1. Mumbai-Pune: cotton textiles, automobiles, chemicals - 1 mark.
2. Hooghly: jute, engineering - 1 mark.
3. Chota Nagpur: iron and steel, heavy engineering - 1 mark.
4. Bengaluru-Tamil Nadu: electronics and software (or Gujarat: petrochemicals) - 1 mark.

Answer: The Mumbai-Pune region is known for cotton textiles, chemicals and automobiles; the Hooghly region for jute and engineering; the Chota Nagpur region for iron and steel and heavy engineering; and the Bengaluru-Tamil Nadu region for electronics and software.

Regional disparities in industrial development

Industrially developed states: Maharashtra, Gujarat, Tamil Nadu, Karnataka, Haryana, and the Delhi region; also parts of West Bengal, Uttar Pradesh (western) and Telangana.
Industrially backward areas: Bihar, much of Uttar Pradesh (eastern), Odisha's interior, the north-eastern states, Jammu and Kashmir, Himachal Pradesh, Madhya Pradesh's interior, Rajasthan's desert districts.

Causes of uneven location:
1. Uneven availability of raw materials, power, water, capital and skilled labour.
2. Colonial legacy: industry grew around the port cities and their hinterlands.
3. Infrastructure: developed regions have better transport, power and communication.
4. Agglomeration and industrial inertia reinforce existing centres.
5. Market size and purchasing power concentrated in large cities.
6. Difficult terrain, poor accessibility, political instability or insecurity in some regions.
7. Differences in state government policies and governance.

Consequences: income and employment gaps between states; migration from backward to developed regions; congestion and pollution in industrial centres.

Measures to reduce disparities: locating public sector plants in backward areas (Bhilai, Rourkela, Bokaro); industrial licensing and concessions for backward districts; growth centres and industrial estates; special packages for the north-east and hill states; industrial corridors and SEZs; improving infrastructure and skills in backward regions.

Worked example

[1] Give one reason why industries are unevenly located in India. (Understand)

Try it first, then show the solutionSolution

1. Name a specific factor that is unevenly available: raw materials, power, transport, market, capital, water or labour (or policy, industrial inertia, colonial legacy) - 1 mark.

Answer: Because the factors industries need, such as raw materials, power, transport, capital, skilled labour and large markets, are available only in certain regions, industries cluster there and other areas remain backward.

Port-based industrial growth: Haldia

Haldia, at the confluence of the Haldi and the Hooghly about 100 km downstream of Kolkata, illustrates how a new port can create an industrial centre.

Why it was established: Kolkata port, 128 km up the Hooghly, suffers from silting and a shallow, winding channel, so large ships cannot reach it. Haldia was built (operational from the 1970s) as a deep-water satellite port to decongest Kolkata and handle bulk cargo such as crude oil, coal, iron ore and fertilisers.

Industries that grew around it: oil refinery (IOCL, Haldia); petrochemicals (Haldia Petrochemicals); fertilisers; chemicals and pharmaceuticals; engineering; port-based warehousing. These are port-based industries using imported raw materials such as crude oil.

(The full case study of Haldia port and its hinterland is in Regional Economic Development.)

Worked example

[3] Why was the port of Haldia established? Name two industries that led to its further growth. (Understand)

Try it first, then show the solutionSolution

1. Established to reduce congestion at Kolkata port and avoid its silting problem, taking large ships - 1 mark.
2. Industry: oil refinery - 1 mark.
3. Industry: petrochemicals (or fertilisers, chemicals) - 1 mark.

Answer: Haldia was established as a deep-water port downstream of Kolkata to decongest Kolkata port, whose channel on the Hooghly silts up, and to handle large ships carrying bulk cargo. Its further growth was led by port-based industries such as the oil refinery and petrochemicals (also fertilisers and chemicals).

Where students lose marks in Location and Distribution of Industrial Centres

The slips examiners see most often, and what to write instead.

• ✗Mistake: Restating that industries are uneven without naming a factor

  CISCE examiners' comments, 2024: on why industries are unevenly located, candidates 'Did not name the factors affecting industrial location' and 'Gave a general statement about uneven location instead of specific factors'.

  ✓Do this: Name a factor: uneven raw materials, power, transport, market, capital, labour, water; or policy, inertia.

  Usually costs: 1 mark.

• ✗Mistake: Naming the port instead of explaining it, and wrong industries

  CISCE examiners' comments, 2025: on the port marked P, candidates 'Named the port Haldia (not required/marks not awarded for naming)' and 'Named Jute and Fishing instead of port-based industries'.

  ✓Do this: Give the reason (decongest silting Kolkata) and port-based industries (refinery, petrochemicals, fertilisers, chemicals).

  Usually costs: Up to 3 marks.

• ✗Mistake: Treating all factors as equally important everywhere

  The decisive factor depends on the industry (raw materials for steel, labour and communication for software).

  ✓Do this: Match the factor to the industry type.

  Usually costs: 1 mark in analysis questions.

• ✗Mistake: Listing remedies when causes are asked

  Mixing parts (a) and (b) of a disparity question.

  ✓Do this: Causes explain why gaps exist; measures say what is done about them.

  Usually costs: 1-2 marks.

   Why did early industries cluster in the Damodar valley?

   Hint

   Coal and water.

   Answer

   Coal for power and fuel, nearby iron ore, water from the Damodar and its tributaries, and rail links to Kolkata.

5. Q5 · 2 marks · Short answerHarder board level

   [2] What is agglomeration economy? Give an example.

   Hint

   Clustering benefits.

   Answer

   The cost advantages firms gain by clustering together, such as shared infrastructure, suppliers, services and skilled labour; for example the automobile cluster around Chennai.

6. Q6 · 4 marks · Short answerHarder board level

   [4] Explain four factors that make Mumbai a major industrial centre.

   Hint

   Port, capital, labour, market.

   Answer

   (1) A natural harbour and major port for importing machinery and raw materials and exporting goods. (2) Capital, banking and the stock exchange. (3) Large supply of skilled and unskilled labour. (4) A huge market and good rail and road links to a cotton-growing, industrial hinterland; historical start with cotton mills (inertia).

7. Q7 · 4 marks · Short answerHOTS / competency

   [4] 'Government policy can overcome the disadvantages of a location.' Evaluate with examples.

   Hint

   Bhilai, SEZs; limits.

   Answer

   Policy can help: public sector plants like Bhilai and Rourkela turned backward districts into industrial towns, and incentives, SEZs and corridors have attracted firms to new areas. But policy cannot fully replace basic advantages: units set up without raw materials, markets or infrastructure, or in insecure areas, often remained small or sick. Policy works best when it builds infrastructure and skills alongside incentives.

8. Q8 · 7 marks · Long answerHOTS / competency

   [7] (a) Distinguish between raw-material oriented and market oriented industries with two examples each. [4]
   (b) Explain why the north-eastern states are industrially backward. [3]

   Hint

   (b) terrain, access, market, capital.

   Answer

   (a) Raw-material oriented industries locate near their raw materials because these are heavy, bulky, weight-losing or perishable, such as iron and steel and sugar. Market oriented industries locate near consumers because their products are perishable, fragile or bulky, such as bakery products and soft drinks. (b) The north-east has rugged, forested terrain and heavy rain that make transport and construction costly; it is connected to the rest of India only through the narrow Siliguri corridor and is far from major markets and ports; and it has limited capital, power infrastructure and skilled labour, with periods of insecurity discouraging investment.
