Detail

1. What tertiary activities are

  • We use services every day. We visit a doctor when ill, send children to a teacher, and hire a lawyer in a court case. All three sell a skill, not a thing.
  • Tertiary activities are services. A service is a special skill that a person provides in return for payment.
  • The output is a service, not a tangible good. A tangible good is a physical object you can touch, such as cloth or steel.
  • Tertiary activities do not process physical raw materials. A barber does not turn iron ore into anything. A miner or a steel plant does.

  • Many fields need professional skills, theoretical knowledge and practical training:

  • health (doctors, nurses)
  • education (teachers)
  • law (lawyers, judges)
  • governance (civil servants)
  • recreation (entertainers, sports trainers)

  • Commercial services: services that are sold for money, such as banking, retail and transport. Tertiary activities produce these in place of factory goods.

  • Official statistics: the World Bank counts these as services:
  • wholesale and retail trade, and repair of motor vehicles
  • hotels and restaurants
  • transport, storage and communication
  • finance, real estate, renting and business activities
  • public administration and defence
  • education, health and social work
  • other community, social and personal services
  • private households that employ people [6]

2. The key input is manpower

  • Manpower means human workers and their skill. It is the main input of tertiary activities. Workers range from skilled labour (plumber, electrician) to trained experts and consultants (doctor, chartered accountant, software consultant).
  • How tertiary differs from secondary activities:
  • Secondary activities (manufacturing and processing) depend on machinery and factory processes.
  • Tertiary activities depend on specialised skills, experience and knowledge.
  • So a service gets better through training and experience, not through a bigger machine.
Feature Primary Secondary Tertiary
What is done Taking resources from nature Turning raw materials into goods Providing skills as services
Output Raw materials (grain, ore, fish) Tangible goods (cloth, steel, cars) Intangible services (treatment, teaching, transport)
Key input Land, natural resources Machinery, factory processes Manpower: skill, experience, knowledge
Raw material processing Extracts it Processes it Does not process it
Examples Farmer, miner, fisher Factory worker, weaver Teacher, doctor, driver, cashier

3. Two parts of tertiary activities: production and exchange

Part What it means How output is seen or measured Examples
Production Providing services that people consume (use up) Indirectly, through wages and salaries, because a service leaves no physical product to count Doctor treating a patient; teacher teaching a class; barber cutting hair
Exchange Trade, transport and communication Movement of goods, people and information Shopkeeper, truck driver, telephone and internet services
  • Why output is measured indirectly: a lesson or a haircut cannot be weighed or counted like tonnes of steel.
  • So we measure the money paid to the person giving the service, in wages, salaries and fees.

  • Why exchange matters: trade, transport and communication help people overcome distance.

  • Producers and consumers live far apart.
  • Trade, transport and communication connect them.
  • Goods, people and information move between places.

4. Examples across the skill ladder

  • Lower to middle skill: plumber, electrician, barber, shopkeeper, driver, cashier.
  • High skill or professional: teacher, doctor, lawyer, publisher.
  • All of them sell a skill or a service. None of them makes a physical product from raw material.

5. The sectoral shift in employment

  • Sectoral shift in employment: as an economy develops, workers move from one sector to another.
  • Workers first move out of the primary sector (farming, mining).
  • They then move into the secondary sector (industry).
  • Above all, they move into the tertiary sector (services).

  • How the shift happens, step by step:

  • Early stage of development: most people work in the primary sector, because farm productivity is low and most labour is needed to grow food.
  • Middle stage: machines and better farming methods free workers from the land. Factories take in many of them, so the secondary sector grows.
  • Developed economy: incomes rise, and people spend more on health, education, banking, travel and entertainment. Most workers are in tertiary activities, and a moderate share remains in the secondary sector.

  • Trend in developed economies: jobs in the tertiary sector keep rising. Jobs in the primary and secondary sectors stay the same or fall.

Stage Largest employer Secondary share Tertiary share
Early or developing Primary Small Small
Industrialising Primary or secondary Rising Rising
Developed Tertiary Moderate, steady or falling Highest, still rising
  • The world picture:
  • Services rose from 53% of global GDP in 1970 to 67% in 2021. That is about two-thirds of world GDP [4].
  • Services now give about 50% of all jobs worldwide [4].
  • Services make up 50% of world trade in value-added terms (counting only the value each country adds), compared with 34% for industry and 16% for agriculture [4].

  • Urban India: services give most of the jobs in Delhi, Mumbai, Chennai and Kolkata. Large cities gather government offices, banks, ports, hospitals, colleges, trade and IT offices.

6. India: services-led growth without services-led jobs

  • Rising share of output: the services share of India's GVA rose from 50.6% in FY14 to about 55.3% in FY25 [2].
  • GVA (Gross Value Added) is the value of all goods and services an economy produces, minus the value of the inputs used to make them.

  • Latest figure: services reached a record 56.4% of GVA in FY26 (First Advance Estimates). Services output grew by about 9.1% in FY26, up from 7.2% in FY25 [3].

  • Share of jobs: services employ only about 30% of India's workforce (PLFS) [2].
  • PLFS (Periodic Labour Force Survey) is MoSPI's regular survey of jobs and unemployment.

  • The gap: services give more than half of India's output but less than a third of its jobs. This pattern is called "services-led growth without services-led jobs".

  • Cause: India's fastest-growing services (IT, finance, telecom) need high skills and employ relatively few people.
  • Result: many workers stay in agriculture or move to low-paid informal services. Few move into factory jobs.
  • Contrast: the usual path is farm → factory → services. India has moved more directly from farm to services.

  • IT-BPM and knowledge outsourcing:

  • IT-BPM means Information Technology and Business Process Management. Firms abroad hand over software, back-office and customer-support work to Indian companies.
  • Share of world services exports: India's share rose from 1.9% in 2005 to about 4.3% in 2023 [5].
  • Telecom, computer and information services: India holds 10.2% of world exports and is the 2nd-largest exporter in the world (Economic Survey 2024-25) [5].

  • These links lead to the notes on sectors-of-economy (economic structure) and india-population (workforce and employment).

Prelims Hooks

  • Tertiary activities produce services, not tangible goods, and do not process physical raw materials.
  • The key input of tertiary activities is manpower (skill, experience, knowledge). For secondary activities it is machinery and factory processes.
  • Output of the production part of services is measured indirectly, through wages and salaries.
  • The exchange part of tertiary activities includes trade, transport and communication, which are used to overcome distance.
  • Trap: a publisher, a cashier and a barber are all tertiary workers. A weaver in a mill is secondary.
  • In a developed economy: most workers are in the tertiary sector and a moderate share is in the secondary sector.
  • In India's four big metros (Delhi, Mumbai, Chennai, Kolkata), most jobs are in services.
  • World services share of GDP: 53% (1970) → 67% (2021). Services also give about 50% of world jobs [4].
  • India, services share of GVA: 50.6% (FY14) → 55.3% (FY25) → 56.4% (FY26 First Advance Estimates) [2][3]. Share of jobs: only about 30% [2].
  • India in telecom, computer and information services exports: 2nd in the world, with a 10.2% share [5].

Mains Points

  • Sectoral shift as a sign of development:
  • What happens: as incomes and productivity rise, labour moves from primary to secondary to tertiary.
  • Where it is seen: developed economies employ most workers in services. Services are about 67% of world GDP and about 50% of world jobs [4].
  • Why it matters: this explains why big cities such as Delhi, Mumbai, Chennai and Kolkata depend on service jobs.

  • India's growth–jobs gap:

  • The gap: services give about 55–56% of GVA but only about 30% of jobs [2][3].
  • Cause: India's high-value services (IT-BPM, finance) need high skills and employ few people. Factory jobs, which usually absorb farm workers, have grown too little.
  • Effect: workers stay in low-productivity farming and informal services, and incomes rise slowly.

  • Policy responses:

  • Train workers through skilling programmes so they can enter skilled service jobs.
  • Encourage services that employ many people, such as tourism, retail, logistics and healthcare.
  • Expand labour-intensive manufacturing alongside services.
  • Spread service hubs to smaller cities so jobs do not gather only in the metros.

  • Services as an export strength:

  • India's share of world services exports rose from 1.9% (2005) to 4.3% (2023) [5].
  • India's IT and knowledge outsourcing makes it the 2nd-largest exporter of computer services [5].
  • This is a major source of foreign exchange.
  • Risks: automation, AI and protectionism (countries shielding their own firms and workers from foreign competition) could threaten these jobs and earnings.
