Primary sector: goods produced by exploiting natural resources (agriculture, fishing, mining). Secondary: natural products changed into other forms through manufacturing. Tertiary (service): activities that help the other sectors (transport, banking, trade, communication) and services such as teaching and health care. GDP is the value of all final goods and services produced within a country in a year. The organised sector has registered enterprises with regular, secure jobs; the unorganised sector is made of small, scattered units largely outside government control.

  2. Vegetable vendor: the others are trained professionals with formal qualifications; the vendor is in the unorganised sector.
  3. Cobbler: the others are employed by the government (public sector); the cobbler is self-employed in the private, unorganised sector.
  4. Air India: it was sold to the Tata Group in 2022 and is now in the private sector; MTNL, Indian Railways and All India Radio are in the public sector.

(i) Farmer (ii) Vegetable vendor (iii) Cobbler (iv) Air India (now privately owned)

5
A research scholar studied working people in Surat: in offices and factories registered with the government – organised, 15%; own shops, offices, clinics in marketplaces with formal licence – 15%; people working on the street, construction and domestic workers – 20%; working in small unregistered workshops – (blank). Complete the table. What percentage of workers are in the unorganised sector?

The last row is per cent. Unorganised sector per cent.

70 per cent of the workers are in the unorganised sector.

6
Do you think the classification of economic activities into primary, secondary and tertiary is useful? Explain how.
Solution

Yes. The classification is useful because:

  • it shows how much each sector contributes to production (GDP) and employment, and how this changes over time, which tells us the stage of development of the economy;
  • it helps the government find problem areas (for example, too many people dependent on agriculture, disguised unemployment) and plan policies for each sector;
  • it shows the interdependence of sectors: e.g. farmers need transport and banks (tertiary), and industries need raw materials (primary);
  • it helps in comparing the economic structure of different countries and states.

Yes; it shows each sector's contribution to output and jobs, reveals problems, helps plan policies, and shows how the sectors depend on each other.

7
For each of the sectors in this chapter, why should one focus on employment and GVA? Could there be other issues which should be examined? Discuss.
Solution
  • GVA shows how much each sector produces, i.e. its contribution to the economy's income and growth.
  • Employment shows how many people depend on each sector for their livelihood. Comparing the two reveals important facts: in India the primary sector's share in GVA has fallen sharply, but it still employs the largest number of people, which shows underemployment in agriculture and a lack of jobs elsewhere.

Other issues to examine:

  • Quality of jobs: wages, job security, working conditions, social security;
  • Income distribution and poverty among workers of each sector;
  • Regional balance, gender equality in employment;
  • Environmental impact and sustainability of each sector;
  • productivity, technology and access to credit.

GVA shows each sector's contribution to output and employment shows how many depend on it; we should also look at the quality of jobs, incomes, inequality, regional balance and environmental effects.

8
Make a long list of all kinds of work that adults around you do for a living. How can you classify them? Explain your choice.
Solution

Example list: farmer, dairy farmer, fisherman, brick-kiln worker, carpenter, tailor, factory worker, mason, shopkeeper, vegetable vendor, teacher, doctor, nurse, bank clerk, auto-rickshaw driver, postman, police constable, software engineer, domestic worker, electrician, mobile repairer.

BasisClassification
Nature of activityPrimary: farmer, dairy farmer, fisherman. Secondary: carpenter, tailor, factory worker, mason, brick-kiln worker. Tertiary: shopkeeper, vendor, teacher, doctor, nurse, bank clerk, driver, postman, police, software engineer, electrician, repairer, domestic worker.
Employment conditionsOrganised: teacher in a government school, bank clerk, postman, police constable, factory worker in a registered factory. Unorganised: vendor, domestic worker, mason, small farmer, auto driver.
OwnershipPublic sector: postman, police constable, government teacher and doctor. Private sector: shopkeeper, software engineer, private factory worker.

The classification by nature of activity is the most basic, since it tells us what kind of work is done; the other two tell us about job security and ownership.

Jobs can be classified by activity (primary, secondary, tertiary), by employment conditions (organised, unorganised) and by ownership (public, private), as in the table.

9
How is the tertiary sector different from other sectors? Illustrate with a few examples.
Solution
  • The primary and secondary sectors produce goods: the primary sector exploits natural resources (e.g. growing wheat, fishing, mining), and the secondary sector converts them into other products by manufacturing (e.g. making flour, cloth, steel).
  • The tertiary sector does not produce goods; it produces services that support the other sectors and people. Examples: transport (trucks carrying wheat to mills), storage (warehouses), communication, banking (loans to farmers and factories), trade (shops selling cloth), and also services such as teaching, health care, law and IT.

The tertiary sector produces services, not goods; it supports the primary and secondary sectors through transport, banking, trade and communication, and provides services such as education and health.

10
What do you understand by disguised unemployment? Explain with an example each from urban and rural areas.
Solution

Disguised unemployment is a situation where more people are working than are actually needed. Everyone seems to be employed, but the extra workers contribute nothing to production; if some of them are removed, total output does not fall. It is also called underemployment.

  • Rural example: a small farmer's plot needs only two people, but five members of the family work on it. Three of them are disguisedly unemployed; if they leave, the output stays the same.
  • Urban example: casual workers such as painters, plumbers or street vendors who search for work every day and get only a few hours of work; or a small shop run by four family members where one or two could handle the work.

When more people work on a job than needed, so that removing some does not reduce output; e.g. five family members on a small farm needing two, or several family members running a small shop.

11
Distinguish between open unemployment and disguised unemployment.
Solution
Open unemploymentDisguised unemployment
A person is willing and able to work but gets no work at allA person appears to be employed, but is not really needed; their contribution to output is zero
Clearly visible; the person is counted as unemployedHidden; everyone seems to be working
Common in the industrial sector and among educated youth in citiesCommon in agriculture, among family members on small farms, and in small family businesses

In open unemployment a person has no work at all and it is visible; in disguised unemployment more people work than needed, so it is hidden.

12
"The tertiary sector is not playing any significant role in the development of the Indian economy." Do you agree? Give reasons.
Solution

No, I disagree. The tertiary sector plays a very significant role:

  • It has become the largest producing sector in India: its share in GVA is more than half (about 53 per cent in 2021-22, from the data in Q24).
  • It provides basic services such as hospitals, schools, post and telegraph, police, courts, transport, banks and insurance, which every country needs.
  • The development of agriculture and industry depends on transport, storage, trade and finance, which are tertiary services.
  • As incomes rise, people demand more services such as eating out, tourism, shopping and private schools.
  • New services based on information and communication technology (software, call centres) are growing rapidly and earn foreign exchange.

However, not all of it is growing equally: many workers in services (small shopkeepers, repair persons, transport workers) barely earn a living, and the sector has not created enough jobs. Still, its role is very significant.

I disagree: the tertiary sector is now the largest contributor to GVA, supports agriculture and industry, provides essential services and fast-growing IT services, though it has not created enough good jobs.

13
The service sector in India employs two different kinds of people. Who are these?
Solution
  • At one end, a limited number of highly skilled and educated workers in services such as banking, IT, finance, medicine and teaching, who earn well and have secure jobs.
  • At the other end, a very large number of workers in low-paid services such as small shopkeepers, repair persons, transport workers (rickshaw pullers, drivers), street vendors and domestic workers, who barely manage to earn a living, often because no other work is available.

Highly skilled, well-paid workers (IT, banking, doctors) and a much larger number of low-paid, unskilled workers (small shopkeepers, repair persons, vendors).

14
Workers are exploited in the unorganised sector. Do you agree? Give reasons.
Solution

Yes, I agree.

  • Low and irregular wages, often below the legal minimum, and no fixed working hours; overtime is not paid.
  • No job security: workers can be asked to leave at any time without a reason; employment is often seasonal.
  • No paid leave, holidays, sick leave, provident fund, gratuity or pension.
  • Poor working conditions: no safety measures, unhealthy surroundings, no medical benefits.
  • The rules and regulations exist but are not followed, as the enterprises are not registered with the government. Most workers are from weaker sections (SCs, STs, landless labourers, women) and cannot bargain.

Yes; unorganised workers get low, irregular wages, no job security, no paid leave or social security, and unsafe working conditions, because laws are not followed.

15
How are the activities in the economy classified on the basis of employment conditions?
Solution
  • Organised sector: enterprises or places of work where the terms of employment are regular, so people have assured work. They are registered by the government and have to follow its rules and regulations (Factories Act, Minimum Wages Act, Payment of Gratuity Act, Shops and Establishments Act). Workers get job security, fixed hours, paid leave, provident fund and medical benefits.
  • Unorganised sector: small and scattered units, largely outside the control of the government. Rules exist but are not followed; jobs are low-paid, often not regular, with no paid leave or job security.

Into the organised sector (registered, regular jobs with security and benefits) and the unorganised sector (small, unregistered units with irregular, insecure jobs).

16
Compare the employment conditions prevailing in the organised and unorganised sectors.
Solution
Organised sectorUnorganised sector
Regular jobs with job securityNo job security; workers can be removed any time
Fixed working hours; overtime is paidLong, irregular hours; no extra pay for overtime
Paid leave, holidays, provident fund, gratuity, pension and medical benefitsNo paid leave, holidays or social security
Safe working environment, as rules must be followedOften unsafe and unhealthy conditions
Registered with the governmentNot registered; largely outside government control
Higher, assured wagesLow and irregular wages

Organised-sector jobs are regular, secure, well paid and come with benefits; unorganised-sector jobs are irregular, insecure, low paid and without benefits.

17
Explain the objective of implementing the MGNREGA 2005 or Viksit Bharat-G RAM G 2025.
Solution

The Mahatma Gandhi National Rural Employment Guarantee Act, 2005 (MGNREGA) implemented the Right to Work in about 625 districts of India. Its objectives were:

  • to guarantee 100 days of employment in a year to all those in rural areas who are able to work and in need of work;
  • if the government fails to provide work, to give unemployment allowance to the people;
  • to give preference to work that would in future increase production from land (e.g. digging wells and ponds, building check dams, afforestation, rural roads), so that rural incomes rise;
  • to reduce poverty and disguised unemployment in rural areas and check migration to cities.

In 2025, MGNREGA was replaced by the Viksit Bharat–Guarantee for Rozgar and Ajeevika Mission (Viksit Bharat-G RAM G 2025), which continues the aim of providing guaranteed wage employment and livelihood support to rural households.

To guarantee rural households wage employment (100 days a year under MGNREGA) or an unemployment allowance, through works that build productive rural assets; the Viksit Bharat-G RAM G Act, 2025 replaced it with the same aim.

18
Using examples from your area, compare and contrast the activities and functions of the private and public sectors.
Solution
Public sectorPrivate sector
The government owns most assets and provides services (e.g. government schools and hospitals, Indian Railways, the post office, electricity boards)Ownership of assets and delivery of services are in the hands of private individuals or companies (e.g. private schools and hospitals, Tata Steel, Reliance, local shops)
Main aim is public welfare, not just profitMain aim is to earn profit
Services are cheaper, sometimes freeServices are often costlier
Raises money through taxesRaises money from owners and loans

Similarity: both provide goods, services and employment, and contribute to the economy.

The public sector is government-owned and works for welfare (government schools, railways, post office); the private sector is privately owned and works for profit (private schools, companies, shops).

19
Fill in the table with one example each from your area of a well managed and a badly managed public sector and private sector organisation.
Solution
Well managed organisationBadly managed organisation
Public sectore.g. Indian Railways reservation and metro rail services, State Bank of India branch, a well-run Kendriya Vidyalayae.g. a government hospital with long queues and shortage of doctors, a poorly maintained bus depot
Private sectore.g. a reputed private hospital or school, a well-known retail chaine.g. a private bus operator with unsafe buses, an unregistered coaching centre or a builder who delays flats

Fill in the actual names of organisations from your own area after discussing with your classmates.

Examples vary by area; the table shows the kind of organisations to list.

20
Give a few examples of public sector activities and explain why the government has taken them up.
Solution

Examples: railways, post offices, roads, bridges, ports, irrigation (dams and canals), electricity generation, schools and colleges, hospitals, the public distribution system (ration shops), police and courts, water supply and sanitation.

Why the government takes them up:

  • Some require huge spending that is beyond the capacity of the private sector (railways, dams, power plants).
  • Collecting money from thousands of users for things like roads and street lights is difficult, so private firms will not provide them, but they are needed by all.
  • Some activities must be supported to keep prices low, such as electricity for farmers and industries, and food grains for the poor.
  • Providing health and education for all, and food and nutrition for the poor, is the duty of a welfare government; private firms would charge high prices.

Railways, roads, power, irrigation, schools, hospitals and ration shops; the government runs them because they need huge investment, private firms will not supply them at affordable prices, and the welfare of all citizens depends on them.

21
Explain how the public sector contributes to the economic development of a nation.
Solution
  • It builds infrastructure (roads, railways, ports, power, irrigation), which is essential for agriculture and industry to grow.
  • It provides essential services such as health, education, water and sanitation, which improve human development.
  • It creates employment on a large scale.
  • It promotes balanced regional development by setting up industries and services in backward areas.
  • It supplies goods at reasonable prices (electricity, food grains through the PDS), protecting the poor and small producers.
  • It reduces inequality and supports the weaker sections through welfare schemes.
  • It uses its earnings for further development and nation-building.

By building infrastructure, providing health and education, creating jobs, developing backward regions, keeping essential goods affordable and reducing inequality.

22
Workers in the unorganised sector need protection on wages, safety and health. Explain with examples.
Solution
  • Wages: unorganised workers are often paid less than the minimum wage. Example: construction and agricultural labourers, and domestic workers, who may be paid very little with no fixed rates. The government should enforce minimum wages and ensure timely payment.
  • Safety: many work in hazardous conditions without safety equipment. Example: workers in fireworks or chemical units, brick kilns, construction sites and manual scavenging. Safety rules must be enforced.
  • Health: they get no medical benefits or paid sick leave, and long hours and unhealthy surroundings damage their health. Example: rag pickers and workers in small textile or bidi units. Health insurance and medical facilities are needed.

The government should also give support through cheap credit, training, social security schemes and registration of workers.

Unorganised workers need minimum wages (e.g. construction labour, domestic workers), safety at work (e.g. fireworks units, brick kilns) and health benefits (e.g. rag pickers, bidi workers).

23
A study in Ahmedabad (1997-98) found that out of 15,00,000 workers, 11,00,000 worked in the unorganised sector. The city's total income was Rs 60,000 million, of which Rs 32,000 million was generated in the organised sector. Present this data as a table. What ways should be thought of for generating more employment in the city?
Solution
SectorNumber of workersShare of workersIncome (Rs million)Share of income
Organised4,00,00026.7%32,00053.3%
Unorganised11,00,00073.3%28,00046.7%
Total15,00,000100%60,000100%

So about a quarter of the workers earn more than half the city's income, while nearly three-quarters share the rest.

Ways to generate more (and better) employment:

  • Set up more small-scale and cottage industries, with cheap credit from banks.
  • Promote the service sector: tourism, IT, transport, health and education.
  • Give skill training and vocational education to workers.
  • Invest in infrastructure (housing, roads, metro), which creates jobs.
  • Help unorganised enterprises to register and grow, and protect workers with minimum wages and social security.

The organised sector has 4 lakh workers earning Rs 32,000 million, the unorganised 11 lakh earning Rs 28,000 million; more jobs can come from small industries, services, skill training, infrastructure and cheap credit.

24
The table gives GVA in Rupees (crore) by the three sectors: 2001-02 – Primary 13,23,000, Secondary 10,40,000, Tertiary 19,31,000; 2021-22 – Primary 24,79,400, Secondary 40,73,000, Tertiary 73,25,000. (i) Calculate the share of the three sectors in GDP for the two years. (ii) Show the data as a bar diagram. (iii) What conclusions can we draw?
Solution

(i) Share . (The question in the book says "2000 and 2013", but the table gives 2001-02 and 2021-22, so we use these years.)

YearTotal GVA (Rs crore)PrimarySecondaryTertiary

Share of the three sectors in GVA, 2001-02 and 2021-22 (calculated from the table)

(iii) Conclusions:

  • The tertiary sector is the largest, and its share has grown from 45 to about 53 per cent: it now produces more than half of India's output.
  • The share of the primary sector has fallen sharply, from about 31 to 18 per cent, even though its output has nearly doubled in value.
  • The secondary sector's share has risen, from about 24 to 29 per cent.
  • So India's economy has shifted from agriculture towards services and industry, though (as the chapter shows) employment has not shifted in the same way.

Shares: 2001-02 – primary 30.8%, secondary 24.2%, tertiary 45.0%; 2021-22 – 17.9%, 29.3%, 52.8%. The tertiary sector has grown to over half of GVA while the primary sector's share has fallen sharply.
