Tertiary activities

Also called: Tertiary sector, Service sector · Topic: Tertiary, Quaternary and Quinary Activities · NCERT: Class 12, Ch 6 "Tertiary and Quaternary Activities"

Meaning

Tertiary activities are economic activities that provide services (a special skill given in return for payment) instead of making tangible goods (physical objects you can touch, such as cloth or steel). They do not process any physical raw material. They matter because, as a country develops, most of its workers move into services. Services now make up about two-thirds of world GDP and give about half of all jobs worldwide [4].

Explanation

What makes an activity "tertiary"

• The output is a service, not a thing.
• A doctor sells treatment, a teacher sells teaching and a lawyer sells legal help.

• None of them turns iron ore, cotton or grain into a product.

• The key input is manpower (human workers and their skill).

• Workers range from skilled labour (plumber, electrician) to trained experts and consultants (doctor, chartered accountant, software consultant).

• Many fields need professional skills, theoretical knowledge and practical training. Examples are health, education, law, governance (civil servants) and recreation (entertainers, sports trainers).

• How it differs from secondary activities:

• Secondary activities (manufacturing) 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
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	Extracts it	Processes it	Does not process it

Two parts: production and exchange

• Production of services: services that people consume (use up), such as a doctor treating a patient or a barber cutting hair.
• Output is measured indirectly, through wages and salaries.

• This is because a lesson or a haircut cannot be weighed or counted like tonnes of steel.

• Exchange: trade, transport and communication (shopkeeper, truck driver, telephone and internet services).

• Producers and consumers often live far apart.

• Exchange helps people overcome distance by moving goods, people and information between places.

• Official list: the World Bank counts these as services [6]:

• 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, and private households that employ people

The sectoral shift: why services grow with development

• Sectoral shift in employment means that as an economy develops, workers move from one sector to another.
• Early stage: most people work in the primary sector. Farm productivity is low, so most labour is needed to grow food.
• Middle stage: machines and better farming methods free workers from the land. Factories take many of them, so the secondary sector grows.
• Developed stage: incomes rise, and people spend more on health, education, banking, travel and entertainment.
• Most workers are in tertiary activities.
• A moderate share stays in the secondary sector.
• Tertiary jobs keep rising, while primary and secondary jobs stay the same or fall.

Where it occurs

• World:
• Services rose from 53% of global GDP in 1970 to 67% in 2021 [4].
• Services 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].

• Developed economies employ most of their workers in services.

• India: share of output and jobs:

• The services share of GVA (Gross Value Added: the value of everything an economy produces, minus the inputs used) rose from 50.6% in FY14 to about 55.3% in FY25 [2].
• It reached a record 56.4% of GVA in FY26 (First Advance Estimates). Services growth rose from 7.2% in FY25 to about 9.1% in FY26 [3].

• But services employ only about 30% of India's workforce, according to the PLFS (Periodic Labour Force Survey, MoSPI's regular survey of jobs) [2].

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

• India in world services trade:
• India's share of world services exports rose from 1.9% in 2005 to about 4.3% in 2023 [5].
• In telecom, computer and information services, India holds 10.2% of world exports. This makes it the 2nd-largest exporter in the world [5].
• This strength comes from IT-BPM (Information Technology and Business Process Management). Firms abroad hand over software, back-office and customer-support work to Indian companies.

Don't confuse with

• Secondary activities: these turn raw materials into tangible goods using machinery. A weaver in a mill is secondary. A cashier, a barber or a publisher is tertiary.
• Primary activities: these take resources directly from nature (farmer, miner, fisher). Tertiary activities neither extract nor process any physical raw material.
• Quaternary activities: these are a specialised, knowledge-based part of services that focus on collecting, processing and spreading information, such as research and IT. Tertiary is the broader group of all services, including routine and low-skill ones like a driver or a barber.
• Production vs exchange (within tertiary): production means services that are consumed and measured indirectly through wages and salaries. Exchange means trade, transport and communication, which overcome distance.

Prelims Hooks

• Tertiary activities produce services, not tangible goods, and do not process physical raw materials. Their key input is manpower. For secondary activities, the key input is machinery and factory processes.
• The output of the production part of services is measured indirectly, through wages and salaries. The exchange part is trade, transport and communication, which overcome distance.
• Trap: a publisher, a cashier and a barber are all tertiary workers. A weaver in a mill is secondary.
• World services share of GDP: 53% (1970) → 67% (2021). Services give about 50% of world jobs [4].
• India, services share of GVA: 50.6% (FY14) → 55.3% (FY25) → 56.4% (FY26 First Advance Estimates), but only about 30% of jobs [2][3].
• In telecom, computer and information services exports, India ranks 2nd in the world with a 10.2% share [5].

Mains Points

• Sectoral shift as a sign of development:
• As incomes and productivity rise, labour moves from primary to secondary to tertiary.
• Services are about 67% of world GDP and about 50% of world jobs [4].

• This explains why Delhi, Mumbai, Chennai and Kolkata depend on service jobs.

• India's "services-led growth without services-led jobs":

• The gap: services give about 55–56% of GVA but only about 30% of jobs [2][3].
• Cause: fast-growing services (IT-BPM, finance, telecom) need high skills and employ few people. Factory jobs, which usually take in farm workers, have grown too little. India has moved more directly from farm to services, skipping the usual farm → factory → services path.
• Effect: many workers stay in low-productivity farming or low-paid informal services, so incomes rise slowly.

• Policy responses: skilling programmes; services that employ many people, such as tourism, retail, logistics and healthcare; labour-intensive manufacturing alongside services; and service hubs in smaller cities, not only in the metros.

• Services as an export strength, and its risks:

• India's share of world services exports rose from 1.9% (2005) to 4.3% (2023), and it is 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.
