Industries
Overview
From raw material to product — that is industry. Cloth, cars, electricity, biscuits — all are products of industry. This chapter covers types of industries, factors affecting their location, and the industrial system.
Typed Notes
What is Industry — Classification
Raw material → process → product = industry. (1) Based on raw material: agro-based (cotton textile, sugar — from farming), mineral-based (iron and steel, cement, aluminium — from mines), marine-based (fish pickle and oil), forest-based (paper, furniture). (2) Based on size: small or cottage — family level (handloom, earthen pots, papad); large scale — big plants with thousands of workers (Tata Steel). (3) Based on ownership: private (Tata, Reliance), public or state-owned (SAIL, railways), joint (both private and public), cooperative (owned by farmers — Amul).
Where Industries are Set Up — Factors of Location
Where should a factory be set up — 8 factors: (1) Nearness to raw material (sugarcane mill near the farm — otherwise it will rot); (2) Water (for processing and cooling); (3) Power or electricity (needed the most); (4) Labour (skilled and available workforce); (5) Transport (road, rail, port — for movement of goods); (6) Market (place where products can be sold); (7) Capital (money for investment); (8) Government policy (concessions and special zones). All these together create industrial belts: Chhotanagpur (iron and coal), Mumbai–Pune, Hooghly (jute).
Industrial System — A Chain
Industry works as a system: (1) Input — raw material (cotton), labour, machines, money; (2) Process — ginning, spinning, weaving, dyeing (cotton → cloth); (3) Output — product (cloth) + profit. And the output of one industry becomes the input of another (cloth → garment factory). Everything is linked — it is a chain. If one link is weak, the whole chain breaks (for example, if electricity goes, the factory stops).
Major Industries — India and the World
(1) Iron and Steel — the 'backbone' of all industries: machines, railways, cars, bridges, buildings are all made from steel — India: Jamshedpur (Tata — the oldest), Bhilai, Rourkela; world: USA and China are the largest producers. (2) Cotton Textile — the oldest industry (Mumbai — called 'cottonopolis', Ahmedabad): warm and dry region — Maharashtra and Gujarat. (3) Jute — Hooghly belt (West Bengal) — used for making sacks. (4) Sugar — Uttar Pradesh, Bihar, Maharashtra (sugarcane belt). Major industrial regions of the world — North America, Europe, East Asia.
Key Concepts
Revision ke liye ek nazar — exam se pehle yahi padhna hai.
- 01Industry = work that processes raw material into a valuable product — cotton into cloth, wheat into flour and biscuits.
- 02Classification: (1) Raw material — agro-based (cotton textile, sugar), mineral-based (iron and steel, cement), marine-based (fish products), forest-based (paper, furniture); (2) Size — small or cottage (handloom, earthen pots) vs. large scale (Tata Steel); (3) Ownership — private (Tata), public or government (SAIL, railways), joint, cooperative (Amul).
- 03Factors of location: nearness to raw material, water, power, labour, transport, market, capital, and government policy.
- 04Industrial system: input (raw material, labour) → processes (machines, work) → output (product) + profit. Everything is linked.
- 05Major industries: Iron and Steel (the backbone — Chhotanagpur belt), Cotton Textile (Mumbai–Ahmedabad — the oldest), Jute (Hooghly), Sugar (Uttar Pradesh–Bihar).

Industry = raw material → product. Types: agro-based, mineral-based, marine-based, forest-based; small scale or large scale; private, public, joint, or cooperative. Location factors: raw material, water, power, labour, transport, market. System: input → process → output. Major industries: iron and steel (Jamshedpur), cotton textile (Mumbai), jute (Hooghly), sugar (Uttar Pradesh).
