Key concepts

Meaning of tertiary activities

NCERT section Introduction

Services are special skills offered for payment: health, education, law, governance and recreation need professional skills, theoretical knowledge and practical training. Manpower is a key component; most tertiary work is done by skilled labour, trained experts and consultants.

Development and employment: in early stages, most people work in the primary sector; in a developed economy, most work in the tertiary sector and a moderate share in the secondary.

Production and exchange:

• Production: 'provision' of services that are 'consumed'; output measured indirectly through wages and salaries.
• Exchange: trade, transport and communication to overcome distance.
• Examples: plumber, electrician, technician, launderer, barber, shopkeeper, driver, cashier, teacher, doctor, lawyer, publisher.

Tertiary vs secondary: services rely on skills, experience and knowledge of workers, not on production techniques, machinery and factory processes.

Worked example

How do tertiary activities differ from secondary activities? (3 marks)

Try it first, then show the solutionSolution

1. Tertiary activities produce services, not tangible goods, and do not process raw materials.
2. Their output is measured indirectly through wages and salaries.
3. They depend on specialised skills, experience and knowledge of workers rather than on machinery and factory processes, as secondary activities do.

Answer: Tertiary activities sell skills and services; secondary activities transform materials with machines.

Trade and commerce: marketing centres

NCERT section Trade and Commerce

Trade is buying and selling items produced elsewhere; retail and wholesale services aim at profit; the places where this happens are trading centres. Trade grew from barter to international money exchange, creating collection and distribution centres.

Rural marketing centres:

• Serve nearby settlements; quasi-urban; the most rudimentary trading centres.
• Personal and professional services are not well developed.
• Local collecting and distributing centres, with mandis (wholesale markets) and retail areas, supplying goods most frequently demanded by rural people.

Periodic markets:

• Found where there are no regular markets; held at intervals (weekly, bi-weekly) on specified dates, moving from place to place.
• People meet their temporally accumulated demand; shopkeepers stay busy every day while serving a large area.

Urban marketing centres:

• More specialised services; ordinary and specialised goods; markets for labour, housing, semi-finished and finished products; services of educational institutions and professionals (teachers, lawyers, consultants, physicians, dentists, veterinarians).

Worked example

What are periodic markets? Why are they useful in rural areas? (3 marks)

Try it first, then show the solutionSolution

1. Periodic markets are held at fixed intervals (weekly or bi-weekly) on specified dates where there are no regular markets.
2. They move from place to place, so people from surrounding areas meet their accumulated demand on market days.
3. Shopkeepers stay busy every day while one set of traders serves a large rural area.

Answer: Rotating weekly or bi-weekly markets that serve dispersed rural demand efficiently.

Retail and wholesale trading

NCERT section Retail Trading; Wholesale Trading

Retail trading: selling goods directly to consumers.

• Mostly in fixed stores devoted to selling.
• Non-store retailing: selling from handcarts and trucks, by hawkers on streets, from house to house, by post or phone orders, through vending machines and over the internet.
• Stores (box): consumer cooperatives were the first large-scale retail innovation; departmental stores delegate purchasing and sales responsibility to department heads; chain stores buy most economically (even having goods made to their specification), employ skilled specialists, and can experiment in one store and apply results to many.

Wholesale trading: bulk business through numerous intermediary merchants and supply houses, not retail stores.

• Some large stores, including chain stores, buy directly from manufacturers, but most retailers get supplies from intermediaries.
• Wholesalers often extend credit so that retailers operate largely on the wholesaler's capital.

Worked example

Distinguish between retail and wholesale trading. (3 marks)

Try it first, then show the solutionSolution

1. Retail trading sells goods directly to consumers, mostly through fixed stores, but also non-store channels like door-to-door, vending machines and the internet.
2. Wholesale trading is bulk business through intermediary merchants and supply houses, supplying retailers rather than consumers.
3. Wholesalers often give credit so retailers run largely on the wholesaler's capital; some chain stores buy directly from manufacturers.

Answer: Retail serves consumers in small quantities; wholesale supplies retailers in bulk, often on credit.

Transport

NCERT section Transport; Network and Accessibility; Factors Affecting Transport

Transport is the service by which people, materials and goods are physically carried from one place to another; an organised industry meeting the basic need for mobility. Modern society needs speedy, efficient transport for production, distribution and consumption; value is enhanced at every stage.

Measuring distance:

• Km distance: actual route length.
• Time distance: time taken on a route.
• Cost distance: expense of travelling on a route.

In choosing a mode, time or cost distance is decisive. Isochrone lines join places equal in travel time.

Network and accessibility: linked places form a network of nodes and links.

• Node: meeting point of two or more routes, an origin, destination or sizeable town on a route.
• Link: every road joining two nodes.
• A developed network has many links, so places are well connected.

Factors affecting transport:

• Demand depends on population size: more people, more demand.
• Routes depend on location of cities, towns, villages, industries and raw materials; pattern of trade; nature of landscape; climate; and funds to overcome obstacles.

Worked example

What are nodes and links? What does a well-developed network indicate? (3 marks)

Try it first, then show the solutionSolution

1. A node is where two or more routes meet, or a starting point, an end point or a large town on a route.
2. A link is every road that joins two nodes.
3. A developed network has many links, meaning places are well connected and accessible.

Answer: Nodes are junctions or places; links are routes joining them; many links mean high connectivity.

Communication

NCERT section Communication; Telecommunications

Communication transmits words, messages, facts and ideas.

• Writing preserved messages and made communication depend on transport (carried by hand, animals, boat, road, rail, air), so all forms of transport are called lines of communication. Efficient transport spreads communication easily.
• Mobile telephony and satellites have made communication independent of transport, but older systems remain because they are cheap; post offices still handle very large volumes of mail.

Telecommunications: linked to modern technology; revolutionised communication by speed: time cut from weeks to minutes. Mobile telephony makes communication direct and instantaneous anywhere, anytime; the telegraph, Morse code and telex are almost things of the past.

Mass media: radio and television relay news, pictures and calls to vast audiences; vital for advertising and entertainment; newspapers cover the whole world.

Satellite communication relays information about the earth and from space; the internet has truly revolutionised global communication.

Worked example

How has telecommunication revolutionised communication? (3 marks)

Try it first, then show the solutionSolution

1. It is based on modern technology and has cut the time for sending messages from weeks to minutes.
2. Mobile telephony makes communication direct and instantaneous at any time from anywhere, making communication independent of transport.
3. Radio, television, satellites and the internet relay information to vast audiences worldwide; old systems like the telegraph and telex are almost obsolete.

Answer: By making communication instant, global and independent of transport.

Services and people engaged in them

NCERT section Services; People Engaged in Tertiary Activities

Levels of services: some serve industry, some people, some both (e.g. transport).

• Low-order services (grocery shops, laundries) are more common than high-order specialised services (accountants, consultants, physicians).
• Gardeners, launderers and barbers do mainly physical labour; teachers, lawyers, physicians and musicians do mental labour.

Regulated services: governments or companies supervise or perform highways and bridges, fire fighting, education and customer care; legislation created corporations to supervise marketing of transport, telecommunication, energy and water supply.

• Professional services: mainly health care, engineering, law and management.
• Recreational and entertainment services locate by market: multiplexes and restaurants within or near the CBD; a golf course where land is cheaper.
• Personal services: facilitate daily life; workers often unskilled rural migrants in domestic work (housekeepers, cooks, gardeners); unorganised. Example: Mumbai's dabbawala (tiffin) service for about 1,75,000 customers.

People engaged: today most people are service workers; developed countries have a higher share in services; service employment is rising, while primary and secondary employment is unchanged or falling.

Worked example

Distinguish between low-order and high-order services with examples. (3 marks)

Try it first, then show the solutionSolution

1. Low-order services, like grocery shops and laundries, are common and widespread.
2. High-order services, like those of accountants, consultants and physicians, are more specialised and less common.
3. Services are provided to consumers who can pay; some involve physical labour (barber) and others mental labour (lawyer).

Answer: Low-order services are common and basic; high-order services are specialised and fewer.

Tourism and medical tourism

NCERT section Some Selected Examples: Tourism; Medical Services for Overseas Patients in India

Tourism: travel for recreation rather than business. The textbook calls it the largest single tertiary activity worldwide, both in registered jobs (250 million) and in revenue (40 per cent of total GDP). Locals provide accommodation, meals, transport, entertainment and special shops; tourism fosters infrastructure, retail and craft (souvenir) industries. Some regions are seasonal; others attract visitors all year.

Tourist regions: warmer places around the Mediterranean coast and the West Coast of India; winter sports regions in mountains; scenic landscapes and national parks; historic towns with monuments, heritage sites and culture.

Tourist attractions:

• Climate: people from colder regions want warm, sunny beach holidays; hence tourism in southern Europe and the Mediterranean (higher temperatures, long sunshine, low rainfall in peak season). Winter holidaymakers want warmth or snow for skiing.
• Landscape: mountains, lakes, spectacular coasts and landscapes not completely altered by humans.
• History and art: ancient or picturesque towns, archaeological sites, castles, palaces and churches.
• Culture and economy: ethnic and local customs; low costs; home-stays such as heritage homes in Goa, Madikere and Coorg.

Medical services for overseas patients in India:

• About 55,000 patients from the USA visited India in 2005 for treatment (small compared with US surgeries).
• India has emerged as the leading country of medical tourism; world-class hospitals in metropolitan cities serve patients worldwide. Medical tourism benefits India, Thailand, Singapore and Malaysia.
• Medical tourism = medical treatment combined with international tourism.
• Outsourcing of medical tests and data interpretation: hospitals in India, Switzerland and Australia read radiology images and interpret MRIs and ultrasound tests; it helps patients if focused on quality or specialised care.

Worked example

What is medical tourism? Why has India emerged as a leader in it? (3 marks)

Try it first, then show the solutionSolution

1. Medical tourism is medical treatment combined with international tourism activity.
2. India has world-class hospitals in metropolitan cities that cater to patients from all over the world (about 55,000 US patients came in 2005).
3. Developing countries like India, Thailand, Singapore and Malaysia benefit greatly; Indian hospitals also do outsourced work like reading radiology images and MRIs.

Answer: Treatment combined with travel; India leads due to world-class metro hospitals serving global patients.

Quaternary and quinary activities, outsourcing and the digital divide

NCERT section Quaternary Activities; Quinary Activities; Outsourcing; The Digital Divide

Knowledge-oriented services (a CEO in Copenhagen or New York, a medical transcriptionist in Bangalore) form the quaternary and quinary activities.

Quaternary activities: collection, production and dissemination of information; centred on research and development; an advanced form of services needing specialised knowledge and technical skills.

• With the tertiary sector, it has replaced most primary and secondary employment as the basis of economic growth; over half of workers in developed economies are in the 'knowledge sector'.
• Examples: mutual fund managers, tax consultants, software developers, statisticians; people in offices, schools, universities, hospitals, theatres, accounting and brokerage firms.
• Can be outsourced; not tied to resources, affected by environment or necessarily localised by market.

Quinary activities: the highest level of decision-makers and policy-makers: creation, re-arrangement and interpretation of ideas, data interpretation and evaluation of new technologies. Called 'gold collar' professions: senior executives, government officials, research scientists, financial and legal consultants. Their importance far outweighs their numbers.

Outsourcing: giving work to an outside agency to improve efficiency and reduce costs; to overseas locations it is off-shoring. Outsourced work: IT, HR, customer support, call centres, sometimes manufacturing and engineering.

• Call centres in India, China, Eastern Europe, Israel, Philippines, Costa Rica created jobs where cheap, skilled workers are available (out-migrating countries; migration may fall). Outsourcing countries face resistance from job-seeking youth. Comparative advantage keeps it going.
• Data processing in Asian, East European and African countries: IT-skilled staff with good English at lower wages; e.g. a firm in Hyderabad or Manila doing GIS work for the USA or Japan; even Botswana.
• New trends: KPO (knowledge processing outsourcing) and 'home shoring' (alternative to outsourcing). KPO differs from BPO as it uses highly skilled workers: information-driven knowledge outsourcing: R and D, e-learning, business research, intellectual property research, legal and banking work; it creates additional business opportunities.

Digital divide: ICT opportunities are unevenly distributed. Developed countries surged ahead; developing countries lagged: the digital divide. It also exists within countries: in India or Russia, metropolitan centres have better connectivity than peripheral rural areas.

Worked example

What is the digital divide? Give an example within a country. (3 marks)

Try it first, then show the solutionSolution

1. Opportunities from information and communication technology are unevenly distributed because of economic, political and social differences; how fast countries provide ICT access decides benefits.
2. Developed countries have surged ahead while developing countries lag behind: this gap is the digital divide.
3. Within countries too, e.g. in India or Russia, metropolitan centres have better connectivity than peripheral rural areas.

Answer: Unequal access to ICT between and within countries, e.g. metros vs rural areas in India.

Where students lose marks in Tertiary and Quaternary Activities

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

• ✗Mistake: Classifying university teaching as tertiary only

  Teaching seems a basic service.

  ✓Do this: The textbook places university classrooms in the quaternary (knowledge) sector.

  Usually costs: 1 mark.

• ✗Mistake: Confusing BPO and KPO

  Both are outsourcing.

  ✓Do this: KPO uses highly skilled workers for knowledge work; BPO handles routine processes.

  Usually costs: 1 mark.

• ✗Mistake: Writing factors affecting tourism

  Older syllabus.

  ✓Do this: Write tourist attractions (climate, landscape, history and art, culture and economy); 'factors affecting tourism' is dropped.

  Usually costs: Relevance.

• ✗Mistake: Defining the digital divide only between countries

  Incomplete.

  ✓Do this: Add divides within countries: metros vs rural areas in India or Russia.

  Usually costs: 1 mark.

5. Q5 · 3 marks · Short answerBoard level

   Explain the role of chain stores in retailing. (3 marks)

   Hint

   Economical buying.

   Answer

   Chain stores purchase merchandise most economically, often having goods manufactured to their own specifications. They employ highly skilled specialists for executive tasks. They can experiment in one store and apply the results to many stores.

6. Q6 · 3 marks · Short answerHOTS / competency

   Suppose a hill state with snow-covered slopes, heritage temples and village home-stays wants to attract tourists throughout the year. Using the chapter, suggest which attractions it can use in different seasons. (3 marks)

   Hint

   Climate, landscape, history, culture.

   Answer

   Winter: snow cover suitable for skiing attracts winter-sports tourists (climate). Summer: cool mountain landscapes, lakes and scenery not completely altered by humans attract people from hot plains (landscape). All year: heritage temples and historic towns (history and art), and low-cost home-stays with local customs (culture and economy), like heritage homes in Goa or Coorg, reduce seasonality.

7. Q7 · 3 marks · Short answerHarder board level

   Name the countries where outsourcing has opened many call centres and explain its effects. (3 marks)

   Hint

   Comparative advantage.

   Answer

   India, China, Eastern Europe, Israel, the Philippines and Costa Rica. It has created new jobs where cheap, skilled workers are available, and may reduce out-migration from these countries. But outsourcing countries face resistance from their own job-seeking youth. Comparative advantage is the main reason it continues.

8. Q8 · 5 marks · Long answerHOTS / competency

   Compare quaternary and quinary activities. (5 marks)

   Hint

   Information vs decisions.

   Answer

   Quaternary activities involve the collection, production and dissemination of information, centred on research and development and requiring specialised knowledge and technical skills; examples: software developers, statisticians, mutual fund managers, tax consultants, people in schools, universities, hospitals and brokerage firms. Over half of workers in developed economies are in this knowledge sector, and such work can be outsourced. Quinary activities are performed by the highest-level decision-makers and policy-makers: creating, re-arranging and interpreting ideas, interpreting data and evaluating new technologies. They are 'gold collar' professions: senior executives, government officials, research scientists, financial and legal consultants; their importance far outweighs their numbers. KPO is a new trend in quinary services.
