Key concepts

Primary, Secondary and Tertiary Sectors

NCERT section Sectors of Economic Activities

There are thousands of economic activities around you. To make sense of them, we group them using a criterion. Here the criterion is the nature of the activity: what does the activity produce?

• Primary sector: produces a good by directly using natural resources. Cotton farming, dairy, fishing, forestry and mining are examples. These depend mainly, though not fully, on nature: rainfall, sunshine, climate or the biological process of animals. It is called primary because it is the base for everything else we make. Since most natural products come from agriculture and related work, it is also called the agriculture and related sector.
• Secondary sector: changes natural products into other forms through manufacturing, in a factory, a workshop or even at home. Cotton becomes yarn and cloth, sugarcane becomes sugar or gur, earth becomes bricks. It is also called the industrial sector.
• Tertiary sector: does not produce a good. It supports production through transport, storage, communication, banking and trade. It also includes essential services such as teachers, doctors, barbers, cobblers and lawyers, and new IT-based services like call centres, ATM booths and software companies. It is called the service sector.

Quick test: ask whether the end result is a natural good, a made good or a service.

Worked example

Classify each of the following into the primary, secondary or tertiary sector and give a reason for each:
(i) A bee-keeper
(ii) A worker in a match factory
(iii) A call centre employee
(3 marks)

Try it first, then show the solutionSolution

1. (i) Bee-keeper: primary sector, because honey is a natural product obtained through the biological process of bees, directly from nature. (1 mark)
2. (ii) Worker in a match factory: secondary sector, because raw materials are changed into a manufactured good, matches, through a factory process. (1 mark)
3. (iii) Call centre employee: tertiary sector, because the person produces a service based on information technology, not a good. (1 mark)

Answer: (i) Primary: honey is a natural product. (ii) Secondary: raw materials are manufactured into matches. (iii) Tertiary: a call centre gives an IT-based service, not a good.

Interdependence of the Three Sectors

NCERT section Sectors of Economic Activities

The three sectors are grouped separately, but they are highly interdependent. A change in one sector quickly affects the others. The chapter shows this with four situations.

• Secondary depends on primary: if farmers refuse to sell sugarcane to a sugar mill, the mill has to shut down, because it has no raw material.
• Primary depends on secondary as a buyer: if companies stop buying Indian cotton and import all of it, cotton prices fall, cultivation becomes less profitable and farmers may go bankrupt if they cannot switch crops.
• Primary depends on secondary for inputs: farmers buy tractors, pumpsets, pesticides and fertilisers. If these become costlier, the cost of cultivation rises and profits fall.
• Everyone depends on tertiary: if transporters go on strike and lorries stop carrying vegetables and milk from villages, food becomes scarce in cities and farmers cannot sell their produce.

Why does this matter? In an answer about development, you must show that growth or trouble in one sector spreads along the chain. That is why the board often asks you to match a sector with how it depends on the others.

Worked example

Read the statements and choose the correct option.
Assertion (A): If lorry owners go on strike, farmers may be unable to sell their vegetables and milk.
Reason (R): The tertiary sector supports the primary and secondary sectors by providing services such as transport.
(a) Both A and R are true and R is the correct explanation of A.
(b) Both A and R are true but R is not the correct explanation of A.
(c) A is true but R is false.
(d) A is false but R is true.
(1 mark)

Try it first, then show the solutionSolution

1. Check A: a transport strike stops produce moving from villages to towns, so farmers cannot sell. A is true.
2. Check R: transport is a tertiary activity that helps the other two sectors. R is true.
3. Link: farmers are hurt precisely because the service that carries their goods has stopped, so R explains A. (1 mark)

Answer: (a) Both A and R are true and R is the correct explanation of A.

Gross Domestic Product and Final Goods

NCERT section Comparing the Three Sectors

To compare sectors, you need the total production of each. But you cannot add cars, nails and computers as numbers. So economists add up values: quantity multiplied by price. For example, 10,000 kg of wheat sold at ₹ 20 per kg is worth ₹ 2,00,000.

One precaution: count only final goods and services, the ones that reach consumers. Goods used up in making final goods are intermediate goods. In the NCERT example, wheat goes to a flour mill, flour goes to a biscuit company, and biscuits reach consumers. The price of the biscuits already includes the value of the flour and wheat. If you add wheat, flour and biscuits, you count the same wheat three times. This is double counting.

The value of final goods and services in a sector in a year is that sector's production. Adding the three sectors gives Gross Domestic Product (GDP): the value of all final goods and services produced within a country during a particular year. It shows how big an economy is. In India a central government ministry estimates it with help from state and union territory departments. For sector shares, the government now uses Gross Value Added (GVA), which adjusts for taxes and subsidies, to match global practice.

Worked example

A farmer grows cotton without buying any inputs and sells it to a spinning mill for ₹ 300. The mill sells the yarn to a weaver for ₹ 500. The weaver sells the finished cloth to a customer for ₹ 900. A student calculates the contribution to GDP as ₹ 300 + ₹ 500 + ₹ 900 = ₹ 1,700.
(a) Identify the error in the student's working.
(b) State the correct value to be included in GDP.
(c) Show that the value-added method gives the same figure.
(3 marks)

Try it first, then show the solutionSolution

1. (a) Cotton and yarn are intermediate goods. Their value is already included in the price of the cloth, so adding them counts the same cotton more than once (double counting). (1 mark)
2. (b) Only the final good, cloth, which reaches the consumer, is counted: ₹ 900. (1 mark)
3. (c) Value added: farmer ₹ 300; mill ₹ 500 − ₹ 300 = ₹ 200; weaver ₹ 900 − ₹ 500 = ₹ 400. Total = ₹ 900, the same as the value of the final good. (1 mark)

Answer: The student double-counted intermediate goods. The correct figure is ₹ 900, the value of the cloth. Value added at each stage (₹ 300 + ₹ 200 + ₹ 400) also totals ₹ 900.

Changing Importance of Sectors and the Rise of the Tertiary Sector

NCERT section Primary, Secondary and Tertiary Sectors in India

The importance of sectors changes as a country develops. In the history of many developed countries, the primary sector came first. Better farming produced more food, so some people could become craftspersons, traders, transporters and administrators, though most still worked on farms. Over more than a hundred years, new manufacturing methods brought factories, and people moved into them. The secondary sector became most important in production and employment. In the past 100 years, developed countries shifted again, to the tertiary sector, which now leads in both production and jobs.

In India, between 1977-78 and 2017-18, production grew in all three sectors but grew the most in the tertiary sector. By 2017-18 it had replaced the primary sector as the largest producing sector. Four reasons:

• Basic services (hospitals, schools, post offices, police, courts, banks, defence) are needed everywhere, and in a developing country the government must provide them.
• Growth of farming and industry raises demand for transport, trade and storage.
• Higher incomes create demand for eating out, tourism, shopping, private schools and hospitals, and professional training.
• New information and communication technology services are growing fast.

But growth is uneven: a few skilled jobs at one end, and a very large number of low-earning small shopkeepers, repair and transport persons at the other.

Worked example

'The tertiary sector has become the largest producing sector in India, but not all of it is growing equally.' Explain this statement. (5 marks)

Try it first, then show the solutionSolution

1. Reason 1: basic services such as hospitals, schools, post offices, police, courts, banks and defence are needed in every country; in a developing country the government provides them. (1 mark)
2. Reason 2: development of agriculture and industry increases demand for transport, trade and storage. (1 mark)
3. Reason 3: as incomes rise, people demand more services like eating out, tourism, shopping, private schools and hospitals, and professional training. (1 mark)
4. Reason 4: new services based on information and communication technology have become essential and are growing rapidly. (1 mark)
5. Uneven growth: only a few services employ highly skilled, educated workers; a very large number of small shopkeepers, repair persons and transport persons barely earn a living because they have no other work. (1 mark)

Answer: In 2017-18 the tertiary sector replaced the primary sector as India's largest producing sector because:
- Basic services like hospitals, schools, police, courts, banks and defence are needed, and the government must provide them.
- Growing agriculture and industry need more transport, trade and storage.
- Rising incomes raise demand for eating out, tourism, shopping, private schools and hospitals.
- New information and communication technology services are expanding fast.
However, growth is uneven. A limited number of services employ highly skilled, educated people, while very many small shopkeepers, repair persons and transport persons barely earn a living. They do this work only because no better jobs are available, so only part of the sector is really growing.

Production Shifted but Employment Did Not: Disguised Unemployment

NCERT section Primary, Secondary and Tertiary Sectors in India

In developed countries, jobs moved along with production. In India, the share of sectors in GVA changed, but employment did not shift in the same way. The primary sector is still the largest employer.

Why? Not enough jobs were created in the secondary and tertiary sectors. Over the forty years, industrial output rose more than nine times but industrial employment only about three times. Service output rose 14 times but service employment only about five times. So more than half of India's workers are still in the primary sector, mainly farming, yet they produce only about one sixth of GVA.

This means there are more people in agriculture than needed. Take Laxmi, a small farmer with about two hectares of rain-fed land. All five family members work on it all year because they have nowhere else to go. Everyone looks busy, but the work is divided and no one is fully employed. If two members leave to work elsewhere, the farm's output stays the same and family income rises.

This is underemployment, also called disguised unemployment, because it is hidden. In open unemployment, a person clearly has no job. Disguised unemployment also exists in cities: casual painters, plumbers and repair persons who do not find work every day, or street sellers who earn very little all day.

Worked example

Between 1977-78 and 2017-18, industrial output in India rose more than nine times but industrial employment rose only about three times. Service output rose 14 times but service employment rose only about five times.
(a) What does this data show about job creation?
(b) How does it explain the situation in the primary sector?
(c) Link it to disguised unemployment.
(3 marks)

Try it first, then show the solutionSolution

1. (a) Production in the secondary and tertiary sectors grew much faster than employment, so not enough new jobs were created there. (1 mark)
2. (b) Workers could not move out of farming, so the primary sector is still the largest employer: more than half the workers produce only about one sixth of GVA. (1 mark)
3. (c) There are more people on farms than needed; each works below potential and removing some would not reduce output. This hidden underemployment is disguised unemployment. (1 mark)

Answer: The data shows output rose much faster than jobs in industry and services, so too few jobs were created. Workers stayed in farming, where more than half the workforce produces about one sixth of GVA. Farms have more workers than needed, each working below potential: this is disguised unemployment.

How to Create More Employment

NCERT section Primary, Secondary and Tertiary Sectors in India

Underemployment in farming and open unemployment both need solutions. The chapter suggests long-term and short-term measures.

Within agriculture: a well, built by the government or with a bank loan, lets Laxmi irrigate and grow a second crop, wheat, in the rabi season. The chapter supposes that one hectare of wheat employs two people for 50 days. Dams and canals for many farms would create much more work.

Linked services: government investment in transport, storage and better rural roads lets farmers sell more and gives jobs in transport and trade. Cheap credit from banks frees farmers from moneylenders' high interest, so they can buy seeds, fertilisers and pumpsets on time.

Semi-rural industry: a dal mill for arhar and chickpea, cold storage for potatoes and onions, honey collection centres near forests, and processing units for vegetables and fruit.

Other sectors: a Planning Commission (now NITI Aayog) study estimated nearly 20 lakh jobs in education alone, and over 35 lakh extra jobs every year from tourism. Health, regional crafts and IT also offer scope.

Short term: the Right to Work law, MGNREGA 2005, in about 625 districts, guaranteed 100 days of work a year to rural people able and in need of work, or an unemployment allowance. Work that raises production from land got preference. In 2025 it was replaced by Viksit Bharat-G RAM G 2025.

Worked example

Imagine you are the head of a village where most families farm small plots of unirrigated land and many members have little work for part of the year. Suggest five measures that would create more employment and raise incomes in your village. (5 marks)

Try it first, then show the solutionSolution

1. Irrigation: build wells, or dams and canals, so farmers can take a second crop such as wheat in the rabi season, giving more workdays on the same land. (1 mark)
2. Cheap credit: banks should lend at a reasonable rate of interest so farmers can buy seeds, fertilisers and pumpsets in time instead of borrowing from moneylenders. (1 mark)
3. Roads, transport and storage: better rural roads, storage and cold storage let farmers sell when prices are good and create jobs in transport and trade. (1 mark)
4. Semi-rural industries: set up units such as a dal mill or food-processing unit that buy local produce and employ local people. (1 mark)
5. Right to Work: use the 100-day guaranteed work under MGNREGA 2005, now replaced by Viksit Bharat-G RAM G 2025, for works that increase production from land. (1 mark)

Answer: - Build wells, dams and canals so farmers can grow a second crop like wheat in the rabi season, creating more workdays.
- Get banks to give farmers cheap credit so they can buy seeds, fertilisers and pumpsets in time, avoiding moneylenders.
- Improve rural roads, transport and storage, including cold storage, so produce sells at good prices and transport and trade jobs grow.
- Set up a dal mill or food-processing unit nearby to process local crops and employ villagers.
- Use the guaranteed 100 days of rural work under MGNREGA 2005, replaced in 2025 by Viksit Bharat-G RAM G 2025, for works that raise production from land.

Organised and Unorganised Sectors

NCERT section Division of Sectors as Organised and Unorganised

This grouping uses a new criterion: the conditions in which people are employed. Are there rules, and are they followed?

The organised sector covers enterprises where terms of employment are regular, so people have assured work. These places 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. It is called organised because it has formal processes. Even self-employed people are organised if they register and follow the rules. Workers here, like Kanta in an office, get an appointment letter, fixed hours, overtime pay, paid leave and holidays, provident fund, gratuity, medical benefits, safe workplaces and a pension on retirement.

The unorganised sector has small, scattered units largely outside government control. Rules exist but are not followed. Jobs, like Kamal's at a grocery shop, are low-paid and irregular, with no overtime, paid leave or sick leave, and no appointment letter. Workers can be asked to leave anytime, for example in a slack season. It also includes many self-employed people doing small jobs like street selling or repairs, and farmers who hire labourers when needed.

The key test is not the type of work but whether the job is registered, regular and protected.

Worked example

Distinguish between the organised and unorganised sectors on any three bases. (3 marks)

Try it first, then show the solutionSolution

1. Registration and rules: organised units are registered with the government and follow laws like the Factories Act and Minimum Wages Act; unorganised units are small, scattered, largely outside government control, and rules are not followed. (1 mark)
2. Job security: organised workers have regular, assured work and an appointment letter; unorganised workers can be asked to leave without any reason. (1 mark)
3. Benefits: organised workers get fixed hours, overtime, paid leave, provident fund, gratuity and pension; unorganised workers get low, irregular pay and no such benefits. (1 mark)

Answer: - Rules: organised units are registered and follow labour laws; unorganised units are outside government control and ignore rules.
- Security: organised jobs are regular with appointment letters; unorganised workers can be removed anytime.
- Benefits: organised workers get overtime, paid leave, provident fund and pension; unorganised workers get low, irregular wages only.

Protecting Unorganised Sector Workers

NCERT section How to Protect Workers in the Unorganised Sector?

Most Indian workers are in the unorganised sector, and they need protection and support. Why is the problem growing?

• Organised sector jobs are the most sought after, but they have been expanding very slowly.
• Some organised enterprises operate in the unorganised sector to evade taxes and avoid labour laws.
• Since the 1990s, many workers have lost organised jobs and moved to low-paid unorganised work, such as selling goods or pushing a cart.

Who needs protection? In villages, the people most at risk are those who own no land and work on other people's farms, farmers with very small plots, farmers who share their crop with the landowner, and craftspeople such as weavers, smiths and carpenters. About four out of every five rural households farm only small or marginal plots, so this group is huge. They need seeds and other inputs on time, credit, storage and places to sell their crops. In towns, the group includes people working in small-scale industry, casual workers in construction, trade and transport, street sellers, porters who carry head loads, garment makers and rag pickers. Small-scale industry needs help to get raw material and to sell what it makes. Many workers from scheduled castes, tribes and backward communities also face social discrimination.

Link to income: when most workers earn low and irregular wages, the average income per person (per capita income) stays low. Many of them are also underemployed, so they produce less than they could. If workers are protected on wages, safety and health, and more of them move into regular, productive work, they earn more and the country produces more. So protection is needed for both economic and social development.

Worked example

In Ahmedabad, researchers counted 15,00,000 workers in all, and 11,00,000 of them did unorganised work. The city earned ₹ 60,000 million in 1997-98, and ₹ 32,000 million of this came from the organised sector.
(a) What percentage of workers were in the unorganised sector, and what share of the city's income did they produce?
(b) Compare the average income per worker in the two sectors.
(c) Suggest one step that would raise the city's average income.
(3 marks)

Try it first, then show the solutionSolution

1. (a) Unorganised workers: 11,00,000 out of 15,00,000, about 73 per cent. Their income: ₹ 60,000 million − ₹ 32,000 million = ₹ 28,000 million, about 47 per cent of the total. (1 mark)
2. (b) Organised: ₹ 32,000 million ÷ 4,00,000 workers = ₹ 80,000 per worker. Unorganised: ₹ 28,000 million ÷ 11,00,000 workers, about ₹ 25,450 per worker. Organised workers earn roughly three times as much. (1 mark)
3. (c) Support small-scale industry with raw material and marketing and make units register and follow minimum wage laws, so more workers get regular, better-paid work; this raises average income per person. (1 mark)

Answer: (a) About 73 per cent of workers were unorganised but produced only about 47 per cent of income. (b) An organised worker earned about ₹ 80,000 against about ₹ 25,450 for an unorganised worker, roughly three times more. (c) Help small-scale units with raw material and marketing and enforce wage laws so more workers earn regular, fair incomes.

Public and Private Sectors

NCERT section Sectors in Terms of Ownership: Public and Private Sectors

The third grouping is by ownership of assets and responsibility for delivering services.

• Public sector: the government owns most of the assets and provides the services. Railways and the post office are examples.
• Private sector: private individuals or companies own the assets and deliver the services, for example TISCO or RIL. Their activities are guided by the motive to earn profit, and you pay them for what you get.

The public sector's purpose is not just profit. The government raises money through taxes and other ways. Why must it act?

• Huge costs: roads, bridges, railways, harbours, electricity and irrigation dams need sums beyond the private sector's capacity. Collecting money from thousands of users is hard, and private firms would charge high rates.
• Supporting others: selling electricity at full cost could force small-scale units to shut, so the government supplies it at affordable rates and bears part of the cost. It buys wheat and rice from farmers at a fair price, stores them, and sells them cheaper through ration shops, helping both farmers and consumers.
• Primary duties: health and education for all, especially elementary education. Infant mortality in Odisha (36) and Madhya Pradesh (43) is higher than in some of the poorest regions of the world. Safe drinking water, housing for the poor, food and nutrition, and spending on the poorest regions are also the government's duty.

Worked example

'The government cannot leave all economic activities to the private sector.' Justify this statement with five reasons. (5 marks)

Try it first, then show the solutionSolution

1. Large investment: roads, bridges, railways, harbours, electricity and dams need sums beyond private capacity, and private firms would charge users high rates. (1 mark)
2. Support to industry: the government supplies electricity at affordable rates so small-scale units do not shut down, bearing part of the cost itself. (1 mark)
3. Support to farmers and consumers: it buys wheat and rice at a fair price and sells them at a lower price through ration shops. (1 mark)
4. Health and education: providing these for all, especially quality elementary education, is the government's duty. (1 mark)
5. Human development and backward regions: safe drinking water, housing for the poor, food and nutrition, and extra spending on the poorest regions. (1 mark)

Answer: The private sector works for profit, so some needs would be unmet:
- Roads, railways, harbours, electricity and dams need huge funds; private firms would charge high rates, so the government builds them for everyone.
- It supplies electricity at affordable rates so small-scale units survive.
- It buys wheat and rice from farmers at a fair price and sells them cheaper in ration shops, helping both groups.
- It must provide health and education for all, especially elementary education.
- It must ensure safe drinking water, housing for the poor, food and nutrition, and spend more on the poorest regions.

Sectors of the Indian Economy in real life

Each concept, met in an everyday situation. Read the situation, answer the question in your own words, then compare with the model answer. The one-line hook is what to remember.

Sectors of the Indian Economy: key facts

Primary sector

Produces goods by directly using natural resources; also called agriculture and related sector.

Use for farming, dairy, fishing, forestry, mining, bee-keeping, flower cultivation.

Secondary sector

Changes natural products into other forms through manufacturing; also called industrial sector.

Manufacturing can be in a factory, workshop or home: a potter or basket weaver is secondary.

Tertiary sector

Provides services that support production, plus essential services; also called service sector.

Transport, storage, communication, banking, trade, teachers, doctors, couriers, call centres.

Three criteria of classification

Nature of activity (primary/secondary/tertiary); employment conditions (organised/unorganised); ownership (public/private).

MCQs often ask which criterion a grouping uses.

GDP

Value of all final goods and services produced within a country during a particular year.

Write all three keywords: final, within a country, particular year.

Intermediate goods

Goods used up in making final goods; not counted separately, to avoid double counting.

Wheat and flour in the biscuit example are intermediate goods.

GVA

Contribution of the three sectors after adjusting for taxes and subsidies.

India now reports sector shares in GVA to match global practice.

2017-18

Tertiary sector became India's largest producing sector, replacing the primary sector.

Use in answers on the rising importance of the tertiary sector.

Production versus jobs (1977-78 to 2017-18)

Industry output rose more than 9 times, jobs about 3 times; service output 14 times, jobs about 5 times.

Proof that not enough jobs were created outside agriculture.

Primary sector today

More than half of workers are in the primary sector but produce only about one sixth of GVA.

Use to explain disguised unemployment.

Disguised unemployment

People seem to be working but all work less than their potential; removing some does not cut output.

Also called underemployment; contrast with open unemployment, which is visible.

MGNREGA 2005

Also called	Right to Work
Guarantee	100 days of work a year
For	rural people able and in need of work
Otherwise	unemployment allowance

Implemented in about 625 districts; replaced in 2025 by Viksit Bharat-G RAM G 2025.

Employment potential (Planning Commission study)

Nearly 20 lakh jobs in education; more than 35 lakh extra jobs every year from tourism.

Use in 5-mark answers on creating employment.

Organised sector laws

Factories Act, Minimum Wages Act, Payment of Gratuity Act, Shops and Establishments Act.

Name one or two when defining the organised sector.

Small and marginal farmers

Nearly 80 per cent of rural households are in this category.

Shows how large the rural unorganised sector is.

Public versus private motive

Private sector works for profit; public sector's purpose is not just profit.

Railways and post office are public; TISCO and RIL are private.

How the board asks Sectors of the Indian Economy

Tricks to remember Sectors of the Indian Economy

Short memory aids. Say each one aloud once, then use it on a question the same day.

• Grown, Made, Served

  Primary = grown or taken from nature. Secondary = made from it. Tertiary = served to help.

  Use it when: Classifying any occupation in a one-mark MCQ or odd-one-out.

Where students lose marks in Sectors of the Indian Economy

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

• ✗Mistake: Adding intermediate goods to GDP

  Students think every sale should count, so they add wheat, flour and biscuits together.

  Wrong working

  GDP = ₹ 20 (wheat) + ₹ 25 (flour) + ₹ 80 (biscuits) = ₹ 125.

  Right working

  Only the final good is counted: ₹ 80 for biscuits, because it already includes the value of wheat and flour.

  ✓Do this: Before adding, ask which good reaches the consumer. Count only that one.

  Usually costs: 1-2 marks in a GDP question.

• ✗Mistake: Describing disguised unemployment as laziness or no work

  The word 'unemployment' makes students think the people are idle.

  Wrong working

  Disguised unemployment is when people do not want to work or work in a lazy manner.

  Right working

  People appear to be working, but more are working than needed, so all work below their potential; removing some does not reduce output.

  ✓Do this: Always include 'appear to work' and 'output does not fall if some leave', plus an example.

  Usually costs: Full 2 marks if the definition is wrong.

• ✗Mistake: Saying the tertiary sector is India's largest employer

  Students mix up the production shift with the employment pattern.

  Wrong working

  The tertiary sector is the largest producer and employer in India.

  Right working

  The tertiary sector is the largest producing sector, but the primary sector is still the largest employer.

  ✓Do this: Keep two lines separate: production moved to services; jobs stayed in farming.

  Usually costs: 1 mark in MCQs, and a value point in 3- and 5-mark answers.

• ✗Mistake: Mixing up the criteria of classification

  Students assume big or famous enterprises are public, or all services are organised.

  Wrong working

  A large private steel company is in the public sector because it employs thousands of workers.

  Right working

  Public or private depends on ownership: a privately owned company is private sector, however large it is.

  ✓Do this: Name the criterion first (nature, employment conditions or ownership), then classify.

  Usually costs: 1 mark per wrong classification.

• ✗Mistake: Putting home-based manufacturing in the primary or tertiary sector

  Students link the secondary sector only with big factories.

  Wrong working

  A potter or basket weaver working at home is in the tertiary sector.

  Right working

  They change raw materials into new goods, so they are in the secondary sector; manufacturing can take place at home.

  ✓Do this: Check the output: a new made good means secondary, wherever it is made.

  Usually costs: 1 mark.

• ✗Mistake: Giving bare points without reasons in 5-mark answers

  Students list headings like 'irrigation, credit, roads' and stop.

  Wrong working

  Measures: irrigation, credit, roads, industries, MGNREGA.

  Right working

  Irrigation through wells and canals lets farmers take a second crop, giving more workdays. (Each point with its reason or result.)

  ✓Do this: Write each point as 'measure plus how it creates jobs or income', within 120 words.

  Usually costs: 2-3 marks in a 5-mark answer.

• ✗Mistake: Wrong features of the Right to Work law

  Students guess that it gives jobs to everyone everywhere.

  Wrong working

  MGNREGA gives permanent government jobs to all unemployed people in India.

  Right working

  MGNREGA 2005 guaranteed 100 days of work a year to rural people able and in need of work, or an unemployment allowance; it was replaced in 2025 by Viksit Bharat-G RAM G 2025.

  ✓Do this: Remember the four anchors: rural, 100 days, allowance if no work, preference to land-improving works.

  Usually costs: 1-2 marks.

1. Q1 · 1 mark · Assertion-reasonBoard level

   Read the statements and choose the correct option.
   Assertion (A): More than half of India's workers are employed in the primary sector.
   Reason (R): The primary sector produces the largest share of India's GVA.
   (a) Both A and R are true and R is the correct explanation of A.
   (b) Both A and R are true but R is not the correct explanation of A.
   (c) A is true but R is false.
   (d) A is false but R is true.

   Hint

   Keep employment share and production share apart.

   Answer

   (c) A is true but R is false. More than half of workers are in the primary sector, but it produces only about one sixth of GVA. Since 2017-18 the tertiary sector has been the largest producing sector. Workers stay in farming because too few jobs were created elsewhere, not because farming produces the most.

2. Q2 · 3 marks · Short answerHarder board level

   Suppose State Y has this GVA (₹ crore). Year 1: primary 40,000, secondary 20,000, tertiary 40,000. Year 2: primary 50,000, secondary 50,000, tertiary 1,00,000. The share of workers in the primary sector was 70 per cent in Year 1 and 65 per cent in Year 2.
   (a) Calculate the primary sector's share of GVA in both years.
   (b) Compare this change with the change in its share of workers.
   (c) What conclusion can you draw? (3 marks)

   Hint

   Find each year's total first. Production can rise while its share falls.

   Answer

   (a) Year 1 total ₹ 1,00,000 crore, primary share 40 per cent. Year 2 total ₹ 2,00,000 crore, primary share 25 per cent.
   (b) Its GVA share fell by 15 points, but its share of workers fell only 5 points, from 70 to 65 per cent.
   (c) Production shifted away from farming much faster than jobs. Too few jobs were created elsewhere, so farming holds more workers than it needs: disguised unemployment.

3. Q3 · 5 marks · Long answerHOTS / competency

   Suppose a town has 10,000 workers. 2,000 work in the organised sector and together earn ₹ 40 crore a year. The other 8,000 work in the unorganised sector and together earn ₹ 24 crore a year.
   (a) What percentage of the town's workers are unorganised? (1)
   (b) Find the average yearly income per worker in each sector and for the town as a whole. What does this show? (2)
   (c) Suggest two steps that would reduce the unorganised sector's drag on the town's income. (2)
   (5 marks)

   Hint

   ₹ 1 crore = ₹ 1,00,00,000. Divide total income by the number of workers.

   Answer

   (a) 8,000 of 10,000 workers = 80 per cent unorganised.
   (b) Organised: ₹ 40 crore ÷ 2,000 = ₹ 2,00,000. Unorganised: ₹ 24 crore ÷ 8,000 = ₹ 30,000. Town: ₹ 64 crore ÷ 10,000 = ₹ 64,000. Most workers earn far below the average, so the large, low-paid unorganised sector pulls the town's average income down.
   (c) Help small-scale units get raw material and markets, and make them register and follow minimum wage and safety rules. Create regular jobs in local industries and services, so more workers move into productive, better-paid work.

4. Q4 · 3 marks · Short answerHarder board level

   Explain how constructing a dam and canals in a dry region can reduce underemployment in agriculture. (3 marks)

   Hint

   Use Laxmi's farm and a second crop.

   Answer

   With irrigation, farmers on rain-fed land can grow a second crop such as wheat in the rabi season. One hectare of wheat can employ two people for 50 days for sowing, watering, fertilising and harvesting. Canals serving many farms create a lot of work within agriculture, so idle family members get productive work.

5. Q5 · 3 marks · Short answerHarder board level

   Why are a large number of workers forced into unorganised sector jobs in India? (3 marks)

   Hint

   Look at both the supply of organised jobs and the behaviour of enterprises.

   Answer

   Organised sector jobs have been expanding very slowly. Many organised enterprises operate as unorganised ones to evade taxes and avoid labour laws. Since the 1990s many workers have also lost organised jobs. So people are pushed into low-paid, insecure unorganised work.

6. Q6 · 5 marks · Long answerHarder board level

   'Spending on health, education and human development is the primary responsibility of the government.' Explain with five points. (5 marks)

   Hint

   Use the chapter's facts on illiteracy, malnutrition and infant mortality.

   Answer

   Running proper schools, especially for elementary education, is the government's duty. India's illiterate population is one of the largest in the world. Nearly half of India's children are malnourished, and a quarter are critically ill. Infant mortality in Odisha (36) and Madhya Pradesh (43) is higher than in some of the poorest regions of the world. The government must also provide safe drinking water, housing for the poor, and food and nutrition. It must spend more on the poorest and most neglected regions. The private sector works for profit and will not do these things on its own.

7. Q7 · 3 marks · Short answerHarder board level

   Show with two examples how the primary, secondary and tertiary sectors depend on one another. (3 marks)

   Hint

   Pick one example of industry needing farms and one of farms needing industry or services.

   Answer

   Secondary depends on primary: if farmers refuse to sell sugarcane to a sugar mill, the mill has to shut down. Primary depends on secondary: farmers buy tractors, pumpsets and fertilisers, so if their prices rise, farming costs rise and profits fall. The tertiary sector links both through transport, storage and trade.

8. Q8 · 3 marks · Short answerHarder board level

   What is Gross Value Added (GVA), and why does the government now report sector contributions in GVA? Also explain why only final goods and services are counted when measuring a sector's production. (3 marks)

   Hint

   Taxes and subsidies, global practice, and the wheat-flour-biscuit example.

   Answer

   GVA measures the contribution of each sector after adjusting for taxes and subsidies. (1)
   The government reports sector contributions in GVA to be at par with global practice. (1)
   The value of a final good already includes the intermediate goods used to make it (wheat and flour inside the biscuits), so counting them separately would count the same value several times. (1)

9. Q9 · 3 marks · Short answerHarder board level

   Classify each worker on all three bases (nature of activity, employment conditions, ownership): (i) a nurse with a regular salary in a government hospital (ii) a labourer hired for harvest on a private farm (iii) a salaried worker in a large, registered privately owned steel plant. (3 marks)

   Hint

   Give three labels for each worker.

   Answer

   (i) Tertiary, organised, public.
   (ii) Primary, unorganised, private.
   (iii) Secondary, organised, private.
   For each worker, you decide the sector by the nature of the activity, the employment conditions and who owns the assets.

10. Q10 · 3 marks · Short answerHOTS / competency

    Suppose a hilly district has forests, scenic spots and an old weaving tradition, but young people leave for city jobs. As a planner, suggest three ways to raise employment there, and say why the government's role matters. (3 marks)

    Hint

    The chapter says every region has its own potential.

    Answer

    Develop tourism, which the Planning Commission study linked to large job gains across the country. Promote the regional craft by helping weavers get raw material and markets. Start honey collection centres in forest villages. Each of these needs proper planning and support from the government, such as roads and credit, to succeed.
