Chapter at a glance

The table below shows at a glance how the chapter is put together — its sections, its figures and the exercise questions it closes with. The chapter’s main parts run in this order:

• Sectors of economic activities — the three-way division by nature of activity, and why the sectors are interdependent (pp. 19–21)
• Comparing the three sectors — counting production, GDP and GVA, and the historical shift between sectors (pp. 22–23)
• Primary, secondary and tertiary sectors in India — Graphs 1–3 on GVA and employment over forty years (pp. 24–25)
• Underemployment and how to create more employment — from disguised unemployment to the Right to Work (pp. 25–29)
• Organised and unorganised sectors — Kanta and Kamal, and protecting unorganised workers (pp. 30–32)
• Public and private sectors — who owns assets, and why the government must act (pp. 33–34)
• Summing Up and exercises — the chapter’s conclusions and its exercise set (pp. 34–37)

Scattered through the pages you will also find Let’s Work These Out activity boxes, where the book asks you to apply each idea before moving on.

What this chapter covers

The whole chapter rests on one idea: an economy is easier to understand once its activities are grouped into sectors. The book groups them three different ways, each on a different criterion.

• By nature of activity — primary, secondary and tertiary sectors.
• By employment conditions — organised and unorganised sectors.
• By ownership of assets — public and private sectors.

Each classification answers a different question: what is produced, how people are employed, and who owns the assets (NCERT, p. 33). The statistics for India come from two official sources: the Economic Survey for GVA data, and the five-yearly employment surveys of the National Sample Survey Organisation (NSSO), now the National Statistical Office (NSO), for employment data (NCERT, p. 18).

This one table is essentially the chapter in miniature — hold it in your head and every later section becomes detail.

Primary, secondary and tertiary sectors

This is the chapter’s first and most important classification. You will define these three sectors and give examples of each, and you should also know why the three depend on one another.

The primary sector produces goods by directly using natural resources. Cotton cultivation and dairy are the book’s first examples; fishing, forestry and mining fit here too. Because most natural products come from agriculture and related work, this sector is also called the agriculture and related sector.

It is called primary because it forms the base for all products made later (NCERT, p. 19).

The secondary sector changes natural products into other forms through manufacturing, which is why it is also called the industrial sector. The chapter’s examples: spinning yarn and weaving cloth from cotton fibre, making sugar or gur from sugarcane, and turning earth into bricks. Making furniture from timber is a fresh example of the same idea (NCERT, p. 20).

The tertiary sector does not produce goods; it provides services that support production. Transport, storage, communication, banking and trade are the core examples, along with teachers, doctors and lawyers, and newer IT-based services like call centres and software companies. Its other name is the service sector (NCERT, p. 20).

The opening photographs on page 19 do the chapter’s first job: they show that goods-producing and service-producing activities are happening around us constantly. The question to ask of each photo is whether that activity produces a good or a service — that question is the seed of the whole classification (NCERT, p. 19).

The three sectors are not isolated boxes. The book stresses that they are highly interdependent, and Table 2.1 on page 20 proves it with examples. If farmers refuse to sell sugarcane to a sugar mill, the mill shuts down — the secondary sector depends on the primary.

If transporters strike and no lorries carry vegetables from villages, food becomes scarce in cities while farmers cannot sell — the tertiary sector’s absence is felt instantly (NCERT, p. 20).

Keep the order with a memory aid that follows one product’s journey: field → factory → shop. The product is first grown or extracted (primary), then processed (secondary), then transported, stored, financed and sold (tertiary). If you prefer a phrase, remember Plant, Shape, Sell.

GDP, GVA and why only final goods are counted

This section answers a practical question: with thousands of goods and services being produced, how do we measure total production without adding apples to trucks?

The answer is to add money values, not quantities. You cannot add 10,000 kg of wheat to 5,000 coconuts, but you can add their rupee values. One precaution makes the number honest: only final goods and services are counted — goods that reach the consumer.

Intermediate goods, which are used up in producing final goods, are not counted separately because their value is already inside the final good (NCERT, p. 22).

Here is a worked example with fresh numbers to show what happens if you ignore that rule:

• A farmer sells wheat to a flour mill at Rs 28 per kg.
• The mill sells the flour to a bakery at Rs 42 per kg.
• The bakery sells the biscuits to consumers for Rs 95.

Add all three sales and you get \(28 + 42 + 95 = \text{Rs } 165\). But the Rs 95 of biscuits already contains the Rs 42 of flour, which already contains the Rs 28 of wheat. Counting all three counts the same wheat three times, so the total comes out too large. The correct contribution to GDP is only Rs 95 — the final good (NCERT, p. 22).

Gross Domestic Product (GDP) is the value of all final goods and services produced within a country during a particular year; it shows how big the economy is. In India, a central government ministry estimates it with help from the state and union territory governments (NCERT, p. 22).

Gross Value Added (GVA) measures the contribution of the three sectors after adjusting for taxes and subsidies. India now reports the sectors’ GVA shares instead of GDP shares, to stay in line with global practice (NCERT, p. 22). The GVA figures in this chapter come from the Economic Survey at 2026-27 prices (NCERT, p. 18).

How India’s sectors changed between 1977–78 and 2026-27

This section applies the first classification to real Indian data across forty years. Keep two questions apart as you read: what does India produce, and who does India employ? The answers do not match, and that mismatch is the chapter’s central point.

Developed countries followed a clear pattern: the primary sector came first, then the secondary sector became most important, and over the past hundred years the shift went further into the tertiary sector, which became dominant in both production and employment (NCERT, p. 23).

Graph 1 shows production in the three sectors for 1977–78 and 2026-27. Production rose in all three, but it rose the most in the tertiary sector, so by 2026-27 the tertiary sector had become the largest producing sector, replacing the primary sector (NCERT, p. 24).

Why is the tertiary sector rising in importance?

The chapter gives four reasons: basic services such as hospitals, schools, courts and banks that a developing country’s government must provide; the demand for transport, trade and storage created by growing agriculture and industry; new services demanded as incomes rise, such as tourism, eating out and private schools; and the recent spread of information-technology services (NCERT, p. 24).

But not all of the service sector is booming. Many of its workers are small shopkeepers, repair persons and transport workers who barely earn a living, simply because no alternative work is available (NCERT, p. 24).

Graph 2 shows each sector’s percentage share of GVA in the two years, so the shifting importance is directly visible. Graph 3 shows the same exercise for employment — and here the picture is different. While production shifted towards the tertiary sector, a similar shift did not happen in employment: the primary sector is still the largest employer (NCERT, p. 25).

The reason is that not enough jobs were created in the secondary and tertiary sectors. Industrial output rose more than nine times between 1977–78 and 2026-27, but industrial employment only about three times; service-sector production rose about fourteen times, but employment only about five times (NCERT, p. 25).

The result is the chapter’s puzzle: more than half of India’s workers are in the primary sector, mainly agriculture, yet they produce only about one-sixth of the GVA. The secondary and tertiary sectors produce the rest with less than half the workers (NCERT, p. 25). That gap is the clue to underemployment, which is the next section.

Underemployment and disguised unemployment

This section explains the key idea behind the puzzle above: what it means to be underemployed, and how underemployment hides inside families and enterprises.

The book’s example is Laxmi, who owns about two hectares of unirrigated land. All five members of her family work on the plot through the year, but the work is shared so thinly that no one is fully employed.

Everyone appears busy and no one is idle — yet if a landlord hires one or two family members, or two take factory jobs, the family earns more and the farm produces just as much (NCERT, p. 26).

That is underemployment: people are apparently working, but all of them are made to work less than their potential. Because it is hidden inside the family — unlike a person with no job, who is visibly unemployed — this kind of underemployment is called disguised unemployment (NCERT, p. 26).

The photograph on page 26 makes the point that underemployment is not limited to farms. Thousands of casual workers in urban areas — painters, plumbers, repair persons and street vendors — may spend the whole day working and still earn very little, purely because better opportunities do not exist (NCERT, p. 26).

One trap to avoid: underemployment has nothing to do with laziness or unwillingness to work. The chapter’s own exercise on page 27 offers four meanings, and the correct one is that underemployment occurs when people are working less than they are capable of doing (NCERT, p. 27).

How to create more employment

This section turns from the problem to solutions: the practical measures the chapter lists for creating more work, and the Right to Work law that guarantees it.

• Irrigation: A well on Laxmi’s land would let her grow a second, rabi crop of wheat. One hectare of wheat can employ two people for about 50 days, so two more family members work in their own field; canals from a new dam scale this up across many farms (NCERT, p. 27).
• Transport and storage: Better rural roads and storage godowns let farmers sell more, which also creates productive employment in transport and trade (NCERT, pp. 27–28).
• Cheap agricultural credit: A bank loan at a reasonable interest rate lets a poor farmer buy seeds, fertilisers and pumpsets, instead of borrowing from a moneylender at high interest (NCERT, p. 28).
• Semi-rural industries and services: A dal mill to process pulse crops, cold storage for potatoes and onions, honey collection centres near forests, and vegetable-processing units all create jobs outside big cities (NCERT, p. 28).
• Education and health: Building schools and hiring teachers could create nearly 20 lakh jobs, and improving rural health needs more doctors, nurses and health workers (NCERT, p. 28).
• Tourism and regional strengths: Every region has potential — tourism, craft industries, new services like IT. Improving tourism alone could add employment for more than 35 lakh people every year (NCERT, p. 29).

The photograph of gur making in Haryana is the book’s example of agro-based work: sugarcane is a natural (primary) product, and turning it into gur is a manufacturing (secondary) activity that can be located in a semi-rural area. That is exactly the kind of employment the chapter wants to create close to where people live (NCERT, p. 28).

Because long-term measures take time, the government also made a quick, guaranteed response. The Mahatma Gandhi National Rural Employment Guarantee Act 2005 (MGNREGA 2005) was implemented in about 625 districts. It guarantees 100 days of employment in a year to all rural people who are able to work and need it.

If the government fails to provide work, it must pay an unemployment allowance; work that improves production from the land gets preference (NCERT, p. 29).

In 2025, MGNREGA 2005 was replaced by the Viksit Bharat-Guarantee for Rozgar and Ajeevika Mission (Viksit Bharat-G RAM G 2025), which carries the same guarantee. In plain language, “right to work” means the government is legally bound to provide work — and pays an unemployment allowance when it cannot (NCERT, p. 29).

The photo above accompanies the passage that makes this point in the book: structural measures are slow, so the government paired them with a quick, guaranteed Right to Work (NCERT, p. 29).

Organised and unorganised sectors

This section switches from what is produced to how people are employed — the rules, security and conditions of work. The book uses two neighbours to make the difference concrete.

Kanta works in an office from 9.30 a.m. to 5.30 p.m. She gets a regular monthly salary, provident fund, medical and other allowances, a paid holiday on Sundays, and an appointment letter stating her terms of work. Kamal, her neighbour, is a daily wage labourer in a grocery shop from 7.30 a.m. to 8.00 p.m.

He gets only his wages — no allowances, no paid leave, no appointment letter, and he can be asked to leave anytime (NCERT, p. 30).

Read the two photographs together: Kanta’s formal, regular employment conditions versus Kamal’s unprotected daily-wage work. The contrast is the whole organised-versus-unorganised idea in one glance (NCERT, p. 30).

Kanta works in the organised sector: enterprises where the terms of employment are regular and assured, which are registered with the government and must follow laws such as the Factories Act, Minimum Wages Act, Payment of Gratuity Act and Shops and Establishments Act (NCERT, p. 30).

Workers in this sector enjoy security of employment, fixed working hours, overtime pay, paid leave, provident fund, gratuity, medical benefits, a safe working environment and pensions on retirement (NCERT, pp. 30–31).

Kamal works in the unorganised sector: small and scattered units largely outside government control, where rules exist but are not followed. Work is low-paid and often irregular; there is no overtime, paid leave, sick leave or job security, and employment depends on the employer’s whims.

Farmers working on their own and hiring labour as needed, street sellers and repair persons also belong here (NCERT, p. 31).

Why do unorganised workers need protection? Organised-sector jobs are the most sought-after but have been expanding slowly, so most workers are forced into the unorganised sector. Some enterprises even shift to the unorganised sector to evade taxes and labour laws, and since the 1990s many organised-sector workers have lost jobs and slipped into low-paid unorganised work (NCERT, p. 32).

The vulnerable groups include landless agricultural labourers, small and marginal farmers, sharecroppers and artisans such as weavers, blacksmiths, carpenters and goldsmiths in rural areas — nearly 80 per cent of rural households are small and marginal farmers. In urban areas they include small-scale industry workers, casual construction and transport workers, street vendors, headload workers, garment makers and rag pickers (NCERT, p. 32).

The picture above accompanies the discussion of who needs protection most, and the book’s point is sharp: many workers from scheduled castes, scheduled tribes and backward communities are concentrated in the unorganised sector, where they face social discrimination on top of low, irregular pay. Protection is needed for both economic and social development (NCERT, p. 32).

Public and private sectors

This section adds the third classification — who owns the assets — and explains why some activities can never be left to the private sector alone.

In the public sector, the government owns most of the assets and provides the services. In the private sector, assets and services belong to private individuals or companies, guided by the motive to earn profit. The railways and the post office are public-sector examples; TISCO and Reliance Industries are private ones.

The government raises money through taxes and other ways to pay for its services, so its purpose is not profit alone (NCERT, p. 33).

The chapter lists three situations that force the government to step in:

• Activities needing huge sums. Roads, bridges, railways, harbours, electricity generation and dams need spending beyond the private sector’s capacity, and collecting money from millions of users is not easy. Even if the private sector provided them, it would charge high rates (NCERT, p. 33).
• Activities the private sector would price too high. Selling electricity at generation cost would raise production costs everywhere and could shut down small units, so the government supplies it at affordable rates and bears part of the cost. In the same way, the government buys wheat and rice at a fair price and sells them cheaper through ration shops, supporting both farmers and consumers (NCERT, pp. 33–34).
• Activities that are the government’s basic duty. Health and education for all — especially elementary education — safe drinking water, housing for the poor, food and nutrition, and care for the poorest regions are responsibilities the government must spend on (NCERT, p. 34).

Figure walkthrough: reading the chapter’s graphs and pictures

This section is a short reading guide so you get something from the chapter’s figures instead of skipping them.

• Opening photos (p. 19): the point is variety. For each picture, ask “goods or services?” — that is the first step of classification.
• Graph 1 (p. 24): read the bar heights for 1977–78 and 2026-27 inside each sector. All three rise, but the tertiary bars rise highest — this graph answers “which sector has grown the most over forty years?” (the question on p. 24).
• Graph 2 (p. 25): percentages of GVA. The primary share falls while the tertiary share rises across the two years, so you can see directly which sector replaced which as the largest producer.
• Graph 3 (p. 25): percentages of employment. Now read the same two years for where people work: the primary share stays dominant. Comparing Graphs 2 and 3 side by side is the entire “largest producer vs largest employer” idea in one glance.
• Underemployment photo (p. 26): apparent work with little earnings — the visual meaning of disguised unemployment outside agriculture.
• Gur making (p. 28): a secondary-sector activity in a semi-rural setting — the chapter’s answer to where new jobs can be created.
• Kanta and Kamal (p. 30): read as a pair. Same neighbourhood, opposite working conditions; every organised-versus-unorganised feature is in the contrast.

Revision summary

Sixty-second version of the chapter, built from its own Summing Up (NCERT, p. 34):

• Three classifications, three criteria. Nature of activity (primary/secondary/tertiary), employment conditions (organised/unorganised) and ownership (public/private).
• Production and employment tell different stories. The tertiary sector contributes most to production, but employment still sits in the primary sector (p. 34).
• Agriculture has more workers than it needs. That hidden underemployment is disguised unemployment; the answer is creating more work elsewhere (pp. 25–27).
• Employment can be created. Through irrigation, cheap credit, transport and storage, semi-rural industries, education, health, tourism — and the Right to Work guarantee (pp. 27–29).
• Most workers are in the unorganised sector. Low pay, irregular work and no security mean they need protection (p. 34).
• The public sector must act where the private sector will not. Huge-cost projects, services priced too high, and basic duties like health and education (pp. 33–34).

Keep the sector order in mind with the journey memory aid: field → factory → shop.

Why does GDP count only final goods and not intermediate goods?

Because the value of intermediate goods is already included in the value of the final good. If a biscuit sells for Rs 95, that price already covers the flour inside it — counting the flour separately would count the same wheat more than once (NCERT, p. 22).

Why is the tertiary sector the largest producer in India but not the largest employer?

Because employment did not shift along with production. Between 1977–78 and 2026-27, industrial output rose more than nine times but industrial employment only about three times, and service-sector output rose about fourteen times while employment rose about five times.

Not enough jobs were created, so the primary sector still employs more than half of India’s workers while producing only about one-sixth of the GVA (NCERT, p. 25).

What is the difference between disguised unemployment and open unemployment?

Open unemployment is visible: a person has no job at all. Disguised unemployment is hidden: people appear to be working, but more people are doing the work than needed, so each works less than their potential — as on Laxmi’s small farm, where removing two workers would not reduce output (NCERT, p. 26).

What is the difference between organised and unorganised sectors?

The criterion is employment conditions. The organised sector has regular and assured terms of employment, is registered with the government, and follows labour laws — giving workers job security, paid leave, provident fund and pensions. The unorganised sector has small, scattered units outside government control, where work is low-paid and irregular and there is no security (NCERT, pp. 30–31).

What is Viksit Bharat-G RAM G 2025 and how is it related to MGNREGA?

MGNREGA 2005 was the law that guaranteed 100 days of employment in a year to rural people who need it, with an unemployment allowance if the government failed to provide work. In 2025 it was replaced by the Viksit Bharat-Guarantee for Rozgar and Ajeevika Mission (Viksit Bharat-G RAM G 2025), which carries the same Right to Work guarantee (NCERT, p. 29).
