What is manufacturing?
Secondary activities add value to natural resources by changing them into goods. Cotton in a boll has little use; spun into yarn and woven into cloth, it becomes valuable. This process is manufacturing. It means making goods by hand or by machine, from a small workshop to a giant factory.
Features of modern large-scale manufacturing
- Specialisation of skills: each worker does one task again and again; goods are made in large numbers at low cost (mass production).
- Mechanisation: machines do the work; the most advanced form is automation, where machines need little human help.
- Technological innovation: research and development (R&D) keeps improving quality and cutting waste.
- Organisational structure and stratification: complex machines, many bosses and workers, big capital, a formal chain of command (managers → supervisors → workers).
- Uneven geographic distribution: large factories are packed in a few areas, often less than 10% of the world's land, mostly in developed regions.
Factors that decide where industries are located
Industries try to keep costs low, so they choose the place with the best mix of:
- Access to market: people who can buy. Developed regions have large markets.
- Access to raw material: cheap and easy to carry. Weight-losing or perishable raw materials (iron ore, sugarcane, milk) pull factories close to them.
- Access to labour: skilled or cheap workers.
- Access to power: industries that use a lot of energy (aluminium) settle near cheap power.
- Transport and communication: cheap, fast movement of raw materials and goods.
- Government policy: tax breaks and plans to develop backward areas.
- Agglomeration economies: factories gain from being near each other (shared services, suppliers, skilled workers).
Footloose industries can be located almost anywhere because they use small, light parts and are not tied to one raw material (for example, electronics). They mostly need road access and skilled workers.
Classification of industries
By size
Household or cottage: smallest; family members at home, simple tools, local raw material (pottery, baskets, handloom). Small scale: workshops, some power machines, hired workers. Large scale: big market, many workers, advanced technology, big capital.
By raw material (inputs)
Agro-based (sugar, cotton textiles, food processing), mineral-based (iron and steel, cement, aluminium), chemical-based (fertilisers, plastics, medicines), forest-based (paper, furniture, lac), animal-based (leather, wool).
By output (product)
Basic industries make goods used by other industries (steel, machine tools). Consumer goods industries make things people use directly (soap, bread, TV).
By ownership
Public sector (run by government), private sector (owned by individuals or firms), joint sector (government and private together).
High-tech industry
High-technology industry is the newest kind of manufacturing. It uses intensive research and development to make advanced goods: computers, chips, aircraft parts, medicines, biotech products.
- Many workers are white-collar professionals (scientists, engineers), not machine operators.
- Robots and computer-aided design are used.
- Buildings are neat, low and modern, often in landscaped office-plant parks, not smoky factory zones.
- Clusters of such industries are called technopolis: for example Silicon Valley near San Francisco, Seattle, and Bengaluru in India.
Key formulas and definitions
- Manufacturing = changing raw material into more valuable goods (value addition)
- Modern manufacturing: specialisation, mechanisation (automation), innovation, organisation, uneven distribution
- Location factors: market, raw material, labour, power, transport, government policy, agglomeration
- Footloose industry = not tied to one raw material; light parts; can locate widely
- By size: cottage → small → large
- By input: agro, mineral, chemical, forest, animal; by output: basic, consumer
- By ownership: public, private, joint
- High-tech = R&D + white-collar workers; clusters = technopolis
Worked examples
1. Why are iron and steel plants often built near iron ore and coal mines?
The raw materials are heavy and lose weight in processing, so it is cheaper to carry the lighter finished steel than the heavy ore.
2. A potter's family makes pots at home and sells them in the village. Which type by size?
Household (cottage) industry.
3. A company makes machine tools used by other factories. Basic or consumer?
Basic industry, because its output is used to make other goods.
4. An electronics firm builds a plant near a highway, far from any mine. Why is this possible?
It is a footloose industry: its parts are small and light, and it is not tied to one raw material.
5. A steel plant is owned by the government. Which ownership type?
Public sector industry.
Common mistakes
- Thinking all industries go to raw materials. Perishable or bulky finished goods (bread, furniture) often go near the market.
- Mixing basic and consumer industries. Basic = for other industries; consumer = for people directly.
- Believing footloose means 'no location factor'. They still need transport and skilled labour.
- Saying high-tech industries need many blue-collar workers. They mainly use white-collar professionals.
