7.1 Primary, secondary and tertiary sectors (NCERT Class 10)

🏫 School level · NCERT Class 9–12 (the base for UPSC, BPSC, SSC and Bank exams)

Classified by the nature of the activity

NCERT Class 10 (Sectors of the Indian Economy) groups all economic activities into three sectors by the nature of the activity:

Table 7.1 The three sectors
Sector	What it does	Examples	Other name
Primary	Uses natural resources directly	Agriculture, dairy, fishing, forestry, mining	Agriculture and related sector
Secondary	Changes natural products into other forms through manufacturing	Sugar from sugarcane, cloth from cotton, bricks, construction, electricity	Industrial sector
Tertiary	Does not produce a good itself but supports the other two	Transport, storage, trade, banking, communication, IT, teaching, health	Service sector

💡 The sectors depend on each other

A farmer (primary) grows sugarcane, a mill (secondary) turns it into sugar, and a truck and a shop (tertiary) carry it to buyers. If the mill closes, the farmer loses a buyer; if trucks stop, both lose. NCERT also uses this to show that GDP counts only final goods (Module 6).

Fig 7.1 Services produce over half of India’s output, but agriculture still employs the largest share of workers. Sources: Economic Survey 2023-24 (GVA at current prices); PLFS 2023-24 (employment).

📈 Structural change: the Fisher–Clark idea

As countries develop, the main source of output and jobs moves from primary to secondary to tertiary (A. G. B. Fisher and Colin Clark). Why the tertiary sector grows: basic services (hospitals, schools, police) are needed everywhere; agriculture and industry need transport, storage and credit; higher incomes raise demand for tourism, restaurants and private schools; and new IT-based services have grown fast. India is unusual: services overtook industry while a large share of workers stayed in agriculture.

⭐ Key Points for Exams

Primary: natural resources; secondary: manufacturing; tertiary: services.
Dairy and fishing are primary; sugar-making is secondary.
India 2023-24: services ≈ 55% of GVA; agriculture ≈ 46% of workers.
Fisher–Clark: development shifts activity from primary to tertiary.

[School] Agriculture, fishing, forestry and mining belong to the:

These activities exploit natural resources directly, which defines the primary sector (also called the agriculture and related sector).

[School] Making sugar from sugarcane is an activity of the:

Growing sugarcane is primary; turning it into sugar through a manufacturing process is secondary; transporting and selling the sugar is tertiary.

[School] The tertiary sector is also called the:

The tertiary sector produces services rather than goods: transport, trade, banking, communication, education and health.

[School · NCERT 10] Dairy farming is an activity of which sector?

NCERT Class 10 says dairy is a primary activity: we depend on the biological process of animals and the availability of fodder. Turning milk into packaged cheese in a factory would be secondary.

[UPSC level] In India’s gross value added at current prices (2023-24), the largest share comes from:

The Economic Survey 2023-24 put services at about 55% of GVA, industry about 28% and agriculture and allied about 18%. Services have been the largest sector for decades.

[Bank PO pattern] According to PLFS 2023-24, which sector employs the largest share of India’s workers?

About 46% of workers were in agriculture in 2023-24, against about 30% in services and about 11% in manufacturing. So agriculture has the largest share of jobs but a small share of output: low productivity and disguised unemployment.

[RBI Grade B level] The Fisher–Clark thesis states that as an economy develops:

A. G. B. Fisher and Colin Clark observed this structural change across countries. India partly fits it: services lead output, but the shift of workers out of agriculture has been slow.

7.2 Organised and unorganised, public and private; disguised unemployment

🏫 School level · NCERT Class 9–12 (the base for UPSC, BPSC, SSC and Bank exams)

Three more ways to divide the same economy

Table 7.2 Organised and unorganised sectors (NCERT Class 10)
Feature	Organised	Unorganised
Registration	Registered with the government; follows laws such as the Factories Act, Minimum Wages Act, Payment of Gratuity Act	Small, scattered units, largely outside government control
Employment	Regular, with formal terms; job security	Low-paid, often not regular; no job security
Benefits	Paid leave, provident fund, medical benefits, fixed hours	No paid leave or holidays; overtime often unpaid
Examples	Bank employees, government teachers, factory workers in large firms	Street vendors, construction labourers, domestic workers, small workshops

📗 Public and private sectors

This classification is by ownership. In the public sector the government owns most assets and provides services (Indian Railways, India Post, many hospitals and schools); the motive is public welfare. In the private sector individuals or companies own the assets (Tata Steel, Reliance Industries); the motive is profit. Some things a society needs (roads, dams, basic health) cost too much or earn too little for private firms, so the government steps in: this links back to the mixed economy (Module 4).

⚠️ Disguised unemployment and underemployment

NCERT’s example: a small farm needs 5 people but all 8 family members work on it. If 3 leave, output does not fall. Those 3 are disguisedly unemployed: they appear to be working, but their marginal productivity is zero. This is common in Indian agriculture and is a form of underemployment. The Mahatma Gandhi National Rural Employment Guarantee Act (MGNREGA), 2005 guarantees 100 days of wage employment a year to every rural household whose adults volunteer for unskilled manual work; if work is not given within 15 days, an unemployment allowance is payable.

🧠 Beyond three sectors (competitive level)

Quaternary: knowledge-based services — research and development, IT, consultancy, information processing (“white-collar” knowledge work).
Quinary: highest-level decision making — senior executives, top government officials, policy makers (“gold-collar” professions).
Both are sub-divisions of the tertiary sector, taught in NCERT Class 12 Human Geography.

⭐ Key Points for Exams

Organised: registered, regular jobs, benefits. Unorganised: small, scattered, insecure.
Public vs private: by ownership.
Disguised unemployment: marginal productivity zero.
MGNREGA 2005: 100 days of wage employment per rural household.
Quaternary = knowledge services; quinary = top decision makers.

[School · NCERT 10] Which is a feature of the organised sector?

Organised enterprises are registered and must follow laws such as the Factories Act and Minimum Wages Act, giving regular jobs, paid leave and provident fund. The other options describe the unorganised sector.

[School] Indian Railways is an example of the:

It is owned and run by the Government of India, so it is in the public sector (and, by activity, the tertiary sector).

[School] MGNREGA, 2005 guarantees every rural household that volunteers for unskilled manual work:

The Act guarantees at least 100 days of wage employment per household per financial year; if work is not given within 15 days of applying, an unemployment allowance is payable. It addresses rural underemployment.

[School] Eight family members work on a farm that needs only five. If three leave, output stays the same. The three are:

They appear to work but add nothing to output; their marginal productivity is zero. Seasonal unemployment is lack of work in some months; frictional unemployment is short gaps while changing jobs.

[SSC pattern] Research and development, IT and consultancy are grouped under the:

Quaternary activities are knowledge-based services. Quinary activities are the highest level of decision making (senior executives, top officials).

[State PSC pattern] “Gold-collar” professions of senior executives and top policy makers belong to the:

NCERT Class 12 Human Geography: quinary activities centre on the creation, rearrangement and interpretation of ideas and on top-level decisions; they are called gold-collar professions.

[School] Which worker is most likely to be in the unorganised sector?

Casual construction labourers usually have no written contract, paid leave or social security, which marks the unorganised sector. The other three have regular, formal jobs.

🎯 Competitive Level (UPSC Pre · BPSC Pre · State PSC · SSC · Bank PO · RBI Grade B): Sectors, jobs and disguised unemployment

Exam map
Exam	What it asks from this module
UPSC Prelims	disguised unemployment (2013); structure of output and employment
BPSC / State PSC	sector shares (India and Bihar), MGNREGA, organised vs unorganised
SSC / Railways	which activity belongs to which sector; quaternary/quinary
Bank PO / RBI Grade B	jobless growth, Fisher–Clark, informality and credit access

🏆 Previous Year Question · UPSC Prelims 2013

UPSC CSE Prelims 2013

Disguised unemployment generally means (a) large number of people remain unemployed (b) alternative employment is not available (c) marginal productivity of labour is zero (d) productivity of workers is low

Disguised: people look employed (working on the family farm) but are surplus.
Removing them leaves output unchanged, so the extra output from the last worker (marginal product) is zero.
“Low productivity” (d) is not the same as zero marginal productivity.

🏛️ BPSC / State PSC pattern (Bihar focus)

Like India, Bihar’s output is now led by the tertiary sector (trade, transport, real estate, public administration), while most of its workers depend on agriculture. BPSC asks this contrast together with MGNREGA and migration. For exact current shares, use the latest Bihar Economic Survey (Finance Department, Government of Bihar), which is released with the State Budget.

🛠️ SSC / Railways quick practice

Quick practice

Classify: (i) fishing (ii) a software engineer writing code (iii) brick kiln (iv) a bank clerk (v) beekeeping

Fishing and beekeeping use natural resources directly: primary.
Brick-making turns clay into a new product: secondary.
Bank clerk and software engineer provide services: tertiary (the software engineer also fits “quaternary”).

(i), (v) primary; (iii) secondary; (ii), (iv) tertiary

🏦 Bank PO / RBI Grade B angle

Jobless growth: GDP rises but jobs do not rise in step, often because growth comes from capital- or skill-intensive services. Informal (unorganised) enterprises find it hard to get bank credit because they lack records and collateral; priority sector lending, MUDRA loans and the Udyam registration portal try to bridge that gap.

⭐ Key Points for Exams

UPSC 2013: disguised unemployment = zero marginal productivity of labour.
Bihar: tertiary leads output; agriculture leads jobs.
Jobless growth: output rises faster than employment.

[UPSC Pre 2013] Disguised unemployment generally means:

Workers who appear employed but whose withdrawal would not reduce output have zero marginal productivity. Low productivity (d) is a weaker condition; (a) describes open unemployment.

[UPSC level] Consider: 1. Services are the largest contributor to India’s GVA. 2. Agriculture is the largest employer in India. 3. Manufacturing employs more workers than agriculture. Which are correct?

Services ≈ 55% of GVA (statement 1 correct); agriculture ≈ 46% of workers (statement 2 correct); manufacturing ≈ 11% of workers, far less than agriculture (statement 3 wrong).

[BPSC pattern] In Bihar’s economy, the sector that contributes the largest share of state output (GSVA) is:

Bihar’s Economic Surveys show the tertiary sector (trade, transport, real estate, public administration) as the largest part of GSVA, even though most workers depend on agriculture. Mining is small in Bihar after the 2000 bifurcation.

[SSC pattern] “Jobless growth” refers to a situation where:

It happens when growth is led by capital- or skill-intensive activities, so output rises much faster than jobs. It is a classic case of growth without development (Module 1).

[Bank PO pattern] Unorganised enterprises find it hard to borrow from banks mainly because they:

Without registration, accounts and collateral, banks cannot assess risk, so informal units turn to moneylenders at high interest. Priority sector lending, MUDRA loans and Udyam registration aim to formalise and finance them.

[School] Classification of the economy into public and private sectors is based on:

Public/private = who owns. Primary/secondary/tertiary = nature of activity. Organised/unorganised = conditions of employment and registration.
