Factors Affecting the Location of Industries (ISC Class 12 Geography)

Updated 18 October 2026 · Fact-checked

Industries locate where the combined costs of raw materials, power, labour, transport and reaching markets are lowest, helped by water, capital, land and government policy. Heavy or weight-losing raw materials pull industries to their source; perishable or bulky products pull them to markets. Industrial inertia, agglomeration and history reinforce existing centres.

Understand Factors Affecting the Location of Industries

1. Physical and economic factors

  • *Raw materials*: heavy, bulky or weight-losing raw materials pull industries to the 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. Light or pure raw materials (cotton textiles) allow location near markets.
  • *Power*: early industries clustered near coalfields (Damodar valley); grids now allow wider dispersal, though power-hungry industries such as aluminium still seek cheap power.
  • *Labour*: cheap or skilled labour attracts industry (textiles in Mumbai and Ahmedabad; IT in Bengaluru).
  • *Market*: perishable, fragile or bulky finished goods locate near consumers (bakeries, soft drinks, furniture).
  • *Transport*: railways, highways and ports cut the cost of assembling and distributing; port cities attract industry.
  • *Water*: for cooling, processing and power (steel, textiles, chemicals, paper); riverside locations in the Hooghly belt and the Damodar.
  • *Capital and banking*: available in big cities. *Land*: cheap, flat land. *Climate*: humid climate helped cotton spinning in Mumbai; not very important now.

2. Political and historical factors

  • *Government policy*: licensing, incentives, subsidies, tax concessions and public sector investment; public sector plants in backward areas (Bhilai, Rourkela, Bokaro); industrial corridors and Special Economic Zones; Make in India and production-linked incentives.
  • *Industrial inertia*: an industry stays where it began even after the original advantage has weakened, because of existing infrastructure, skilled labour and links (Mumbai's cotton mills, Jamshedpur).
  • *Agglomeration economies*: industries cluster to share infrastructure, suppliers, services and skilled workers (automobile clusters around Chennai, Pune and Gurugram).
  • *Political stability and law and order.*
  • *Historical factors*: colonial ports and their hinterlands (Mumbai, Kolkata, Chennai) became the first industrial centres.
  • *Banking, insurance and entrepreneurship.*

3. Types 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).

4. Why industries are unevenly located. Because the factors industries need are unevenly available, existing centres are reinforced by inertia and agglomeration, and policy differs between states.

5. A transport-cost sum (imaginary). To make 1 tonne of steel needs 3 tonnes of raw material at Rs 6 per tonne per 100 km transport, and the finished steel moves at the same rate. If the plant is at the mine, moving the steel 400 km costs 1 x 6 x 4 = Rs 24. If it is at the market, moving the raw materials 400 km costs 3 x 6 x 4 = Rs 72. Locating at the mine saves 72 - 24 = Rs 48 per tonne, which is why such industries are raw-material oriented. (The rates are invented.)

Factors Affecting the Location of Industries in real life

The idea, met in an everyday situation. Answer the question in your own words, then compare with the model answer. The one-line hook is what to remember.

Raw material pull

Suppose a sugar mill is built at a village in the middle of a cane belt, though the city is 60 km away.

Why is it located there?

Try it first, then show the solutionSolution
  1. Cane loses sucrose soon after cutting.
  2. Locating near the fields saves transport time and loss.

Answer: The raw material is bulky and perishable, so the mill is raw-material oriented.

Memory hook: Cane to the mill, not the mill to the city.

Industrial inertia

Imagine a textile cluster still operates in an old port city although cotton is now grown far inland.

Name the reason it stays.

Try it first, then show the solutionSolution
  1. Existing mills, skilled workers and markets make moving costly.

Answer: Industrial inertia.

Memory hook: Staying put is cheaper than moving.

Ordered from board level to HOTS. Try each one before you open the solution.

Example 1: Footloose industry · 1 mark · MCQBoard level

An industry not tied to raw materials or power that can locate almost anywhere with good communication and skilled labour is called:
(a) raw-material oriented (b) market oriented (c) footloose (d) basic

Try it first, then show the solutionSolution
  1. This is the definition of a footloose industry, such as electronics or software.

Answer: (c)

Example 2: Industrial inertia · 2 marks · Short answerBoard level

What is industrial inertia? Give one Indian example.

Try it first, then show the solutionSolution
  1. An industry continues at its original location even after the original advantages have weakened.
  2. Example: Mumbai's cotton mills or Jamshedpur.

Answer: Staying at the original site after the advantage has gone; Mumbai's cotton mills.

Example 3: Where to locate · 4 marks · Short answerHarder board level

To make 1 tonne of steel needs 3 tonnes of raw material. Transport costs Rs 6 per tonne per 100 km. Calculate the cost of moving the product 400 km from a mine-site plant and of moving the raw materials 400 km to a market-site plant, and decide the location. (Rates are invented.)

Try it first, then show the solutionSolution
  1. Mine-site plant: move 1 tonne of steel 400 km = 1 x 6 x 4 = Rs 24.
  2. Market-site plant: move 3 tonnes of raw materials 400 km = 3 x 6 x 4 = Rs 72.
  3. Saving at the mine = 72 - 24 = Rs 48 per tonne.
  4. Locate near the raw materials: a weight-losing, raw-material oriented industry.

Answer: Rs 24 against Rs 72; locate at the mine; saving Rs 48 per tonne.

Example 4: Match the factor · 4 marks · Short answerHarder board level

Try it first, then show the solutionSolution
  1. (i) Market: perishable product.
  2. (ii) Power: power-hungry industry.
  3. (iii) Skilled labour (and footloose nature).
  4. (iv) Government policy.

Answer: (i) market, (ii) power, (iii) skilled labour, (iv) government policy.

Example 5: Planning an industrial park · 8 marks · Long answerHOTS / competency

Suppose a state wants to attract a car-making cluster. Identify at least six factors it must provide, linking each to the theory of industrial location, and explain how a cluster, once formed, tends to grow.

Try it first, then show the solutionSolution
  1. Transport: highways, rail and a port for parts and exports.
  2. Power and water in assured supply.
  3. Skilled and semi-skilled labour and training institutes.
  4. Capital and banking, and cheap flat land.
  5. A market and a stable political environment with supportive policy, such as incentives or an SEZ.
  6. Suppliers nearby: agglomeration economies reduce costs.
  7. Once formed, the cluster grows through agglomeration and industrial inertia, as around Chennai, Pune and Gurugram.
  8. Conclusion: factors work together; no single factor decides.

Answer: Transport, power, water, labour, capital, policy and suppliers; clusters grow by agglomeration and inertia.

Where students lose marks in Factors Affecting the Location of Industries

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

  • Mistake: Listing factors without examples

    Indian examples earn marks.

    Wrong working

    Raw materials, power, labour.

    Right working

    Raw materials: steel near iron ore and coal in Chota Nagpur.

    Do this: One example each.

    Usually costs: 1-2 marks.

  • Mistake: Confusing inertia with agglomeration

    Different ideas.

    Wrong working

    Inertia is industries clustering to share services.

    Right working

    That is agglomeration; inertia is staying after the advantage has gone.

    Do this: Stay versus cluster.

    Usually costs: 1 mark.

  • Mistake: Wrong industry type

    Footloose is not raw-material oriented.

    Wrong working

    Software is raw-material oriented.

    Right working

    Software is footloose.

    Do this: Learn the three types.

    Usually costs: 1 mark.

Exam tips

  • Group factors in your answer and give an example for each.
  • Use correct industrial terms: inertia, agglomeration, footloose.
  • Link sugar to cane, steel to ore and coal, cement to limestone.
  • Questions asking for reasons for the uneven distribution of industries are common in ISC papers.

Practice questions on Factors Affecting the Location of Industries

Write each answer on paper first. Open the hint only if you are stuck, and the answer only when you have finished.

  1. Q1 · 1 mark · Very short answerBoard level

    Why do sugar mills locate near cane fields?

    Hint

    Sucrose.

    Answer

    Cane loses sucrose soon after cutting, so the mill must be near the fields.

  2. Q2 · 2 marks · Short answerBoard level

    State two ways in which government policy affects industrial location.

    Hint

    Backward areas.

    Answer

    Public sector plants in backward areas (Bhilai, Rourkela, Bokaro) and incentives such as tax concessions, Special Economic Zones and industrial corridors.

  3. Q3 · 2 marks · Short answerHarder board level

    What are agglomeration economies?

    Hint

    Clusters.

    Answer

    The cost advantages that industries gain by clustering together and sharing infrastructure, suppliers, services and skilled workers, as in the automobile clusters around Chennai, Pune and Gurugram.

  4. Q4 · 4 marks · Short answerHarder board level

    A factory moves 8 tonnes of raw material and 2 tonnes of finished product, each over 200 km, at Rs 5 per tonne per 100 km. Compute the total transport cost.

    Hint

    Total tonnes times rate times distance.

    Answer

    Total tonnes moved = 8 + 2 = 10 tonnes. Cost = 10 x 5 x 2 = Rs 100 (200 km is 2 units of 100 km).

  5. Q5 · 4 marks · Short answerHOTS / competency

    A mill owner says 'We stay in this old city because of tradition, not economy.' Examine the claim using industrial inertia.

    Hint

    Cost of moving.

    Answer

    Partly right. Industrial inertia is the tendency to stay after the original advantage has gone, but it has economic reasons: existing factories, skilled labour, infrastructure and links would be lost by moving. So tradition is backed by the cost of relocation, not tradition alone.
