Why this chapter matters for UPSC: Industrial location is one of the oldest themes in GS1 geography: why steel plants sit near coal and ore or near ports, why mini mills sit near cities, why textiles moved to low-wage countries, why high-tech firms cluster on the edges of metropolitan areas. In the 2026-27 NCERT reprint the chapter is Chapter 5, "Secondary Activities", but shorter: it drops the sections on traditional large-scale industrial regions, the Ruhr, the iron and steel industry and the cotton textile industry. They stay on this page, marked as 2021-22 text, because Mains has asked about the world map of steel more than once.

Contemporary hook: The world made 1,849.4 million tonnes of crude steel in 2025, according to the World Steel Association. China made 960.8 Mt, down 4.4%; India made 164.9 Mt, up 10.4%, and is the second-largest producer, far ahead of the USA (82.0 Mt) and Japan (80.7 Mt). The location logic NCERT teaches is visible in the inputs: a tonne of steel from a blast furnace needs about 1.4 tonnes of iron ore and 0.8 tonnes of coking coal, which is why integrated plants were built on the coalfields and ore belts.

🧠 First Principles — Read This First

Secondary activities add value by transforming raw materials. NCERT's examples are simple: cotton in the boll has limited use, but spun into yarn it becomes valuable; iron ore cannot be used straight from the mine, but turned into steel it becomes machines and tools. Secondary activities are therefore "concerned with manufacturing, processing and construction (infrastructure) industries". Manufacturing ranges from handicrafts to moulding steel and assembling spacecraft, and its common features are the application of power, mass production of identical products, and specialised labour in factories.

Every industry is located where its costs are lowest. "Industries maximise profits by reducing costs", so they settle where the total cost of getting raw materials in, power and labour, and products out to the market is least. Bulky, weight-losing raw materials pull industries towards their sources; perishable ones too; power-hungry industries go to cheap energy; others go to the market, to skilled labour, to good transport, to where governments offer incentives, or to where other industries already are. Each industry in this chapter is an application of that rule.

PART 1 — Quick Reference

Factors of Industrial Location (NCERT)

Factor	NCERT's point	Example (NCERT)
Access to market	The most important factor; a market is people with demand and purchasing power	Europe, North America, Japan, Australia; dense South and South-east Asia; aircraft and arms have global markets
Access to raw material	Cheap, bulky, weight-losing materials pull industry to the source; perishables too	Steel, sugar, cement; agro-processing, dairy
Labour supply	Some manufacturing still needs skilled labour; mechanisation reduces dependence
Sources of energy	Power-intensive industries locate near energy	Aluminium
Transport and communication	Moving raw materials in and goods out; managing information	Western Europe, eastern North America
Government policy	Regional policies for balanced development
Agglomeration economies	Savings from links with a leader industry and other industries

Footloose industries "can be located in a wide variety of places": they do not depend on any specific raw material, use components obtainable anywhere, produce in small quantities, employ few workers, are generally non-polluting, and depend mainly on road access.

PART 2 — Concepts & Narrative

Manufacturing and "Manufacturing Industry"

Manufacturing literally means "to make by hand", but now includes goods made by machines: it is "a process which involves transforming raw materials into finished goods of higher value for sale". An industry is a geographically located manufacturing unit that keeps accounts and records under a management system. Because "industry" is also used for activities that are not carried on in factories (the entertainment industry, the tourism industry), NCERT uses the longer term manufacturing industry for clarity. Most Third World countries still "manufacture" in the literal sense.

Features of Modern Large-Scale Manufacturing

Specialisation of skills and methods. The craft method makes a few pieces to order at high cost; mass production makes large quantities of standardised parts, each worker repeating one task.
Mechanisation and automation. Mechanisation uses gadgets to do tasks; automation, work without the aid of human thinking during production, is its advanced stage, with feedback and closed-loop computer control.
Technological innovation through research and development, for quality control, cutting waste and inefficiency, and combating pollution.
Organisational structure and stratification: complex machine technology, extreme specialisation and division of labour, vast capital, large organisations and executive bureaucracy.
Uneven geographic distribution. Major concentrations cover less than 10% of the world's land and have become centres of economic and political power. Manufacturing is far more intensive than farming: NCERT's example is that 2.5 sq km of the American Corn Belt holds about four large farms employing 10-20 workers and supporting 50-100 people, while the same area could hold several large factories employing thousands.

Classifying Industries

NCERT classifies manufacturing industries in four ways (the figure in Part 1 shows all four):

By size, measured by capital, workers and volume of production:

Household or cottage manufacturing, the smallest unit: artisans use local raw materials and simple tools at home with family or part-time labour; goods are for the household, the village market or barter (foodstuffs, fabrics, mats, containers, tools, furniture, shoes, pottery, bricks, jewellery, bamboo crafts).
Small-scale manufacturing: a workshop outside the home, local raw materials, simple power-driven machines and semi-skilled labour; it provides jobs and raises local purchasing power, which is why India, China, Indonesia and Brazil developed labour-intensive small-scale industry.
Large-scale manufacturing: a large market, varied raw materials, enormous energy, specialised workers, advanced technology, assembly-line mass production and large capital; it developed over the last 200 years in the UK, the north-eastern USA and Europe and has since spread almost everywhere.

By inputs or raw materials:

Agro-based: food processing (canning, cream, fruit processing, confectionery), sugar, pickles, juices, beverages (tea, coffee, cocoa), spices, oils and fats, textiles (cotton, jute, silk) and rubber. Agri-business is "commercial farming on an industrial scale often financed by business whose main interests lie outside agriculture", mechanised and reliant on chemicals: "agro-factories".
Mineral-based: ferrous (iron and steel), non-ferrous (aluminium, copper, jewellery) and non-metallic (cement, pottery).
Chemical-based: petrochemicals from mineral oil; salts, sulphur and potash; synthetic fibre and plastics; chemicals from wood and coal.
Forest-based: timber for furniture; wood, bamboo and grass for paper; lac.
Animal-based: leather, wool, and ivory from elephant tusks.

By output or product: basic industries make products used as raw materials for other goods (iron and steel → textile machines → clothes); consumer goods (non-basic) industries make goods consumed directly (bread, biscuits, tea, soap, writing paper, televisions).

By ownership: public sector (owned and managed by governments; India's PSUs; state-owned industries in socialist countries); private sector (owned by individual investors; typical of capitalist countries); joint sector (joint stock companies, or public and private sectors together). Mixed economies have both public and private enterprises.

Key Term

Weight-losing raw materials and footloose industries: the two ends of location

At one end, an industry whose raw material is bulky and loses weight in processing (iron ore and coal into steel, cane into sugar, limestone into cement) saves transport cost by locating at or near the source: it would be wasteful to carry the waste across the country. At the other end, a footloose industry uses light components available anywhere and makes small, high-value products, so no raw material ties it down; road access and other factors decide. NCERT's exercise turns on this: the statement that "sugar, cotton textiles and vegetable oils are footloose industries" is wrong, because they are tied to agricultural raw materials.

Two Types of Industrial Region

NCERT groups the world's major industrial regions under large-scale manufacturing into two types: traditional large-scale industrial regions, thickly clustered in a few developed countries, and high-technology industrial regions, which have spread to less developed countries.

Traditional regions (2021-22 text) are based on heavy industry, often near coalfields: metal smelting, heavy engineering, chemicals or textiles, now called smokestack industries. They are recognised by a high share of employment in manufacturing; high-density, often inferior housing and poor services; an unattractive, polluted environment with waste heaps; and unemployment, emigration and derelict land after factory closures.

The Ruhr coalfield, Germany (2021-22 text) was long one of Europe's major industrial regions, built on coal and iron and steel. As demand for coal fell, industry shrank; after local ore ran out, steelmaking continued on ore imported by waterway. NCERT states that the Ruhr produced 80% of Germany's steel (an undated figure). Its future, NCERT says, lies less in coal and steel and more in new industries such as the Opel car plant, chemical plants and universities, with out-of-town shopping centres: a "New Ruhr" landscape.

Iron and Steel (2021-22 text)

The iron and steel industry is a basic industry, because its products are raw materials for other industries such as machine tools, and a heavy industry, because it uses large quantities of bulky raw materials and its products are heavy. Iron is extracted from iron ore by smelting in a blast furnace with carbon (coke) and limestone; the molten iron is cooled into pig iron, which is converted into steel by adding strengthening materials such as manganese.

Location. The large integrated steel plant is traditionally located close to its raw materials (iron ore, coal, manganese and limestone) or where they can be easily brought, such as ports. Mini steel mills depend more on markets than inputs: they are cheaper to build and run, use scrap as their main input, and do only one step, steelmaking. NCERT notes that mini mills are gaining ground. The World Steel Association's averages show why. The blast-furnace route (about 70% of world steel) uses 1,370 kg of iron ore, 780 kg of metallurgical coal, 270 kg of limestone and 125 kg of recycled steel per tonne of crude steel; the electric arc furnace route (about 30%), the technology of the mini mill, uses 710 kg of recycled steel, 586 kg of iron ore, 150 kg of coal, 88 kg of limestone and 2.3 GJ of electricity. The figure below sets the two side by side.

Inputs are worldsteel's averages per 1,000 kg of crude steel. Dark boxes are the products; orange-edged boxes are the location rule NCERT gives for each route. Sources: World Steel Association, "Raw materials" (accessed 3 October 2026); NCERT Class XII, Fundamentals of Human Geography, ch. 6, "Iron and Steel Industry".

Distribution. NCERT calls steel one of the most complex and capital-intensive industries, concentrated in the advanced countries of North America, Europe and Asia:

USA: the north Appalachian region (Pittsburgh), the Great Lakes (Chicago-Gary, Erie, Cleveland, Lorain, Buffalo, Duluth) and the Atlantic coast (Sparrows Point, Morrisville); the industry has also moved south to Alabama. Pittsburgh "is now losing ground" and has become the "rust bowl" of the USA.
Europe: the UK (Scunthorpe, Port Talbot, Birmingham, Sheffield), Germany (Duisburg, Dortmund, Düsseldorf, Essen), France (Le Creusot, St Étienne), Russia (Moscow, St Petersburg, Lipetsk, Tula) and Ukraine (Krivoi Rog, Donetsk).
Asia: Japan (Nagasaki, Tokyo-Yokohama), China (Shanghai, Tianjin, Wuhan) and India (Jamshedpur, Kulti-Burnpur, Durgapur, Rourkela, Bhilai, Bokaro, Salem, Visakhapatnam and Bhadravati).

The 2025 production table in Part 1 shows how far the map has moved since NCERT's list: China alone made more than half the world's steel, and India is second.

Jamshedpur, India's first steel town. Tata Steel records that the Tata Iron and Steel Company was registered on 26 August 1907 and that the first ingot of steel was rolled in February 1912. Its coal came from the Jharia coalfield, where the company's collieries began operating in 1910, and the iron-ore deposits of the Gorumahisani hills in Mayurbhanj had been found by the geologist P. N. Bose in 1903.

Cotton Textiles (2021-22 text)

The cotton textile industry has three sub-sectors. The handloom sector is labour-intensive, employs semi-skilled workers and needs little capital; it covers spinning, weaving and finishing (NCERT asks why Gandhi promoted Khadi in the freedom movement). The powerloom sector uses machines, needs less labour and raises output. The mill sector is highly capital-intensive and produces fine cloth in bulk.

The industry needs good-quality cotton. NCERT names India, China, the USA, Pakistan, Uzbekistan and Egypt as producing more than half of the world's raw cotton, and notes that the UK, north-western Europe and Japan make textiles from imported yarn, with Europe accounting for nearly half of world cotton imports. Facing stiff competition from synthetic fibres, the industry has declined in many countries: Germany's cotton textile industry grew from the Second World War until the 1970s and then declined, shifting to less developed countries with low labour costs.

High-Technology Industry

High-tech is "the latest generation of manufacturing activities": intensive research and development leading to products of an advanced scientific and engineering character. White-collar professional workers greatly outnumber blue-collar production workers. Robots on assembly lines, computer-aided design and manufacturing, electronic control of smelting and refining, and new chemical and pharmaceutical products are typical. The landscape is one of neatly spaced, low, modern office-plant-lab buildings, and planned business parks for start-ups are now part of regional development schemes. High-tech industries that are regionally concentrated, self-sustained and highly specialised are called technopolies: Silicon Valley near San Francisco and Silicon Forest near Seattle.

Explainer

Why high-tech industry settles on the edges of big cities (NCERT exercise)

NCERT asks why high-tech industries are attracted to the peripheral areas of major metropolitan centres. The chapter's own features give the answer. High-tech plants need space for "neatly spaced, low, modern, dispersed" office-plant-lab buildings and planned business parks, which are easier to find on the urban fringe than in the crowded core. They draw on the professional, white-collar workforce and the universities and research bodies of the metropolis, and they gain agglomeration economies from being near one another. Their products are light and high-value, so, like footloose industries, they depend more on road access than on raw materials. And regional and local development schemes now plan such business parks deliberately. A technopoly such as Silicon Valley is the result: regionally concentrated, self-sustained and highly specialised.

NCERT ends by naming iron and steel, textiles, automobiles, petrochemicals and electronics as some of the world's most important manufacturing industries.

India's Industry Today

Manufacturing employed 12.1% of India's workers in 2025, up from 11.6% in 2024 (PLFS Annual Report 2025). In technology services, NASSCOM's Strategic Review 2026 (February 2026) estimates that India's technology industry grew 6.1% to about $315 billion in FY2026, with exports above $246 billion. To spread IT-enabled work beyond the big metros, the India BPO Promotion Scheme, run by Software Technology Parks of India, supports BPO and ITES units in smaller cities with up to 50% of capital and operating expenditure, capped at ₹1 lakh per seat, for 48,300 seats with an outlay of ₹493 crore (STPI).

PART 3 — UPSC Integration

UPSC Connect

Cross-paper relevance

GS1 (Geography): factors of industrial location; world and Indian distribution of steel and textiles; why industries shift.
GS3 (Economy, Infrastructure): manufacturing's share of jobs, small and large industry, IT-BPM, regional policy and industrial corridors.
Essay: themes on industrialisation and the environment, and the future of work.

Frames that score. For "why are steel plants moving away from raw materials?", combine NCERT's integrated-versus-mini-mill contrast with the input data: the blast-furnace route needs ore and coking coal by the tonne, the electric-arc route mostly scrap and electricity, so the second can sit near markets and ports. For "spatial change in the world steel industry", use NCERT's centres, the rust bowl and the 2025 production table. For India's textiles, use NCERT's three sectors and the shift of the industry to low-wage countries.

Exam Strategy

For Prelims: Learn the seven location factors with NCERT's examples, the footloose definition, the four classifications and their categories, the features of traditional industrial regions, the meaning of technopolies (Silicon Valley, Silicon Forest), the Indian steel centres, and the 2025 steel ranks.

For Mains: Use the factor table as a checklist, pick the two or three factors that dominate for the industry asked about, and support them with a dated example.

Avoid: calling agro-based industries footloose (NCERT's exercise trap) and repeating "3-4 tonnes of raw material per tonne of steel": worldsteel's average for the blast-furnace route is about 2.4 tonnes of ore, coal and limestone.
