- Economic activities are grouped into three sectors by the nature of activity: primary (nature-based, e.g. farming), secondary (manufacturing), tertiary (services).
- GDP = value of all final goods and services produced within a country in a year — the standard measure of an economy's size.
- In India the tertiary sector now produces the most (largest share of GVA), but the primary sector still employs the most people — leading to underemployment / disguised unemployment.
- A second classification by conditions of work gives the organised (secure, regulated) and unorganised (insecure, scattered) sectors; a third by ownership gives the public and private sectors.
- MGNREGA 2005 (now replaced by Viksit Bharat–G RAM G 2025) guarantees 100 days of wage employment a year in rural areas — the "Right to Work".
- Board weightage: ~4 marks/year — favourites are GDP/final goods, disguised unemployment, organised vs unorganised, and MGNREGA.
1. Why classify the economy into sectors?
Around us, people are busy in countless economic activities — some produce goods (a farmer growing cotton, a worker baking bricks), others produce services (a teacher, a courier, a banker). To make sense of this huge variety, economists group activities using some sensible criterion. Each group is called a sector.
The same activities can be sorted in different ways depending on what we want to find out. This chapter uses three different criteria, giving three classifications:
- By nature of activity → primary, secondary, tertiary.
- By conditions of work / employment → organised, unorganised.
- By ownership of assets → public, private.
Classification is just a tool to analyse a situation — to see which sectors are big, which create jobs, and where problems lie.
2. Primary, secondary and tertiary sectors
This first classification is based on the nature of the activity.
| Sector | What it does | Also called | Examples |
|---|---|---|---|
| Primary | Produces goods by directly exploiting natural resources | Agriculture & related sector | Farming, dairy, fishing, forestry, mining |
| Secondary | Changes natural products into other forms through manufacturing | Industrial sector | Cotton → cloth, sugarcane → sugar/gur, earth → bricks |
| Tertiary | Provides services that support the other two sectors | Service sector | Transport, storage, communication, banking, trade, teaching, IT |
Why "primary"? Because it forms the base for all other products — everything we manufacture starts from a natural product (cotton, sugarcane, ore). The product of the primary sector is mostly a natural product, depending mainly, but not entirely, on natural factors like rainfall, sunshine and climate.
The secondary sector is the next step: the product is not produced by nature but is made through some process of manufacturing — in a factory, a workshop or even at home.
The tertiary sector is different from the first two: these activities by themselves do not produce a good but are an aid or support to production. Goods made in the primary/secondary sectors need to be transported, stored, sold (trade), and money may need to be borrowed (banking). The service sector also includes essential services like teachers, doctors, lawyers, washermen, barbers and cobblers, plus new IT-based services such as internet cafes, ATMs, call centres and software companies.
The three sectors are highly interdependent. If farmers refuse to sell sugarcane, the sugar mill (secondary) shuts down. If fertiliser prices rise, farmers' (primary) profits fall. If transporters strike, food does not reach cities (tertiary failure hurts everyone). No sector can stand alone.
3. Comparing the three sectors — counting production
Once we have the three sectors, the next step is to measure how much each produces and how many people each employs. But thousands of different goods and services are produced — you cannot simply add up cars and computers and nails and furniture.
The trick: use the value (in money) of goods and services, not their physical numbers. If 10,000 kg of wheat is sold at Rs 20 per kg, its value is Rs 2,00,000; 5000 coconuts at Rs 15 each is worth Rs 75,000. Add up such values across each sector.
Only final goods and services are counted, never intermediate goods. Example: a farmer sells wheat to a flour mill at Rs 20/kg; the mill sells flour to a biscuit company at Rs 25/kg; the company sells biscuits to consumers at Rs 80. Only the Rs 80 (the final good) is counted — because its value already includes the value of the flour (Rs 25) and the wheat (Rs 20). Counting wheat and flour separately would mean counting the same thing several times (double counting).
4. GDP and GVA
Gross Domestic Product (GDP) is the value of all final goods and services produced within a country during a particular year. The value of final goods produced in each sector gives that sector's total production; summing across all three sectors gives the GDP. GDP shows how big the economy is.
In India this mammoth task is carried out by a central government ministry, which (with the help of departments in all states and union territories) collects data on the total volume of goods and services and their prices, and estimates the GDP.
Recently the Indian Government also reports the Gross Value Added (GVA) of the three sectors, to be at par with global practice. GVA measures each sector's contribution to the economy after adjusting for taxes and subsidies. (The detailed difference between GDP and GVA is for higher classes — here GVA is simply used to compare how the sectors have changed.)
In the early stages of development, the primary sector was the most important. As farming methods improved, more food was produced and people took up crafts, trade and other work. Over a hundred years, with new methods of manufacturing and expanding factories, the secondary sector became the most important. In the past 100 years there has been a further shift — in developed countries the tertiary (service) sector has become the most important in both production and employment. This is the general pattern in developed countries.
5. The three sectors in India — rising tertiary sector
Graph 1 in the NCERT compares GVA of the three sectors in 1977–78 and 2017–18. Over these forty years production in all three sectors grew, but it grew most in the tertiary sector. As a result, by 2017–18 the tertiary sector has emerged as the largest producing sector in India, replacing the primary sector.
Why is the tertiary sector becoming so important in India?
- Basic services: in any country, hospitals, schools, post offices, police, courts, defence, transport, banks and insurance are needed. In a developing country the government takes responsibility for providing these basic services.
- Linked to growth: as agriculture and industry develop, they create demand for services like transport, trade and storage. The more the primary and secondary sectors grow, the more such services are needed.
- Rising incomes: as incomes rise, people (especially in cities) demand more services — eating out, tourism, shopping, private hospitals, private schools, professional training.
- New IT services: over the past decade or so, services based on information and communication technology have become essential and have grown rapidly.
The service sector employs very different kinds of people. At one end are a limited number of highly skilled, well-paid jobs. At the other end are a very large number of workers — small shopkeepers, repair persons, transport persons — who barely manage to earn a living because no better opportunities exist. So only part of the service sector is truly growing in importance.
6. Where are most people employed?
A remarkable fact about India: although the share of the three sectors in GVA changed, a similar shift did NOT happen in employment. The primary sector continues to be the largest employer even now.
Graph 3 of the NCERT shows the share of employment: in 1977–78 the primary sector employed about 71% of workers; even in 2017–18 it still employed about 44%. Meanwhile the primary sector produces only about one-sixth of the GVA, while the secondary and tertiary sectors together produce the rest while employing only about half the people.
Why didn't workers shift out of the primary sector? Because not enough jobs were created in the secondary and tertiary sectors. Even though industrial output went up by more than nine times and service output by about fourteen times over the period, employment in industry rose only about three times and in services only about five times. So people had nowhere else to go and stayed in agriculture.
7. Underemployment / disguised unemployment
Because there are more people in agriculture than is necessary, the workers there are underemployed: they are apparently working, but all of them are made to work less than their potential. Even if a few people are moved out, production will not fall.
Laxmi owns about two hectares of unirrigated land growing jowar and arhar. All five members of her family work on the plot the whole year because they have nowhere else to go. None remains idle, yet the labour effort gets divided — no one is fully employed. If two members moved out (say, to work on a landlord's field or in a factory), the farm's output would not fall, and the family's total income would rise.
This kind of underemployment is hidden: unlike a person who has no job and is clearly visible as unemployed, here everyone looks busy. So it is also called disguised unemployment. It happens in other sectors too — e.g. casual service workers (painters, plumbers, street vendors) who may spend the whole day but earn very little because they have no better opportunity.
Why worry about it? Because it means a large share of the workforce is not being used productively. If these people were given proper work elsewhere, total output and incomes would rise — so it is a waste of the country's human resources.
8. How to create more employment
The NCERT suggests several measures, mostly aimed at rural areas where underemployment is high:
- Irrigation & credit: the government or banks can fund a well so Laxmi can take a second crop in the rabi season — providing more days of work for her family and others. Cheap agricultural credit reduces dependence on moneylenders.
- Better transport, storage and rural roads: so farmers can sell their surplus — this also creates jobs in transport and trade.
- Local industries in semi-rural areas: a dal mill (for arhar/chickpea), a cold storage (for potatoes/onions), honey-collection centres near forests, or units that process vegetables and farm produce — all generate employment near villages.
- Social sectors: a Planning Commission (now NITI Aayog) study estimated nearly 20 lakh jobs could be created in education and many in health; tourism could add over 35 lakh jobs a year if improved.
For the short term, quick measures are needed. The Union Government made a law — the Mahatma Gandhi National Rural Employment Guarantee Act 2005 (MGNREGA 2005) — implemented in about 625 districts. Under it, all those who are able to and in need of work in rural areas are guaranteed 100 days of employment in a year by the government. If the government fails to provide work, it must give an unemployment allowance. Types of work that help raise future production from land are given preference. Because it legally guarantees a job, it is called the "Right to Work". In 2025 this Act was replaced by Viksit Bharat–Guarantee for Rozgar and Ajeevika Mission (Viksit Bharat–G RAM G 2025).
9. Organised and unorganised sectors
This second classification is based on the conditions of work — the rules and regulations that apply to employment.
| Organised sector | Unorganised sector | |
|---|---|---|
| Meaning | Enterprises where terms of employment are regular; registered by government; must follow its rules | Small, scattered units largely outside government control; rules exist but are not followed |
| Job security | Secure; cannot be removed easily | Insecure; can be asked to leave anytime |
| Hours & pay | Fixed hours; overtime paid; assured salary | Long hours; low, often irregular pay; no overtime |
| Benefits | Paid leave, provident fund, gratuity, medical benefits, pension, safe conditions | No paid leave, no PF, no benefits |
| Example | Kanta — office worker with appointment letter, PF, paid holidays | Kamal — daily-wage grocery worker, no letter, no leave |
The organised sector is governed by laws such as the Factories Act, Minimum Wages Act, Payment of Gratuity Act, Shops and Establishments Act. Even some self-employed people are "organised" if they register and follow rules. Most workers in India (over 90%) are in the unorganised sector; organised-sector employment is available to only a small share.
10. Protecting workers in the unorganised sector
Organised-sector jobs are the most sought-after, but they have expanded very slowly. Worse, many organised enterprises behave like unorganised ones — to evade taxes and avoid labour laws. So a large number of workers are forced into the unorganised sector, where pay is low, jobs are insecure, and workers are often exploited. Since the 1990s many workers have also lost organised jobs and slipped into low-paid unorganised work.
Who needs protection?
- Rural: landless agricultural labourers, small and marginal farmers (nearly 80% of rural households are small/marginal farmers), sharecroppers, artisans (weavers, blacksmiths, carpenters, goldsmiths). They need timely seeds, inputs, credit, storage and marketing.
- Urban: workers in small-scale industry, casual workers in construction, trade and transport, street vendors, head-load workers, garment makers, rag pickers.
- A majority of workers from Scheduled Castes, Scheduled Tribes and backward communities are in the unorganised sector and also face social discrimination.
Protecting and supporting these workers is necessary for both economic and social development.
11. Public and private sectors
This third classification is based on the ownership of assets and who is responsible for delivering services.
| Public sector | Private sector | |
|---|---|---|
| Owner | The government owns the assets and provides services | Private individuals or companies own the assets |
| Main motive | Public welfare (not just profit) | To earn profit |
| Examples | Railways, post office | Tata Iron and Steel Company (TISCO), Reliance Industries Limited (RIL) |
Why must the government (public sector) spend on certain activities?
- Costly infrastructure the private sector won't provide at a reasonable cost — roads, bridges, railways, harbours, electricity generation, irrigation through dams. These need huge sums and would be charged at high rates by private firms.
- Activities the government must support — e.g. supplying electricity cheaply so industries survive; buying wheat and rice from farmers at a fair price, storing it, and selling at low prices through ration shops (Public Distribution System).
- Primary responsibilities of government — providing health and education for all, safe drinking water, housing for the poor, food and nutrition, and special attention to the poorest, most ignored regions (India has high illiteracy, child malnutrition and infant mortality, e.g. in Odisha and Madhya Pradesh).

Q5. Surat workers table. Own shops/clinics with formal licence = organised (15%); street/construction/domestic workers = unorganised (20%); small unregistered workshops = unorganised (the remaining 50%, since 15+15+20=50). Total unorganised = 20 + 50 = 70%. Organised = 15 + 15 = 30%.
Q6. Is the primary/secondary/tertiary classification useful? Yes. It lets us see how much each sector produces and how many it employs, compare them over time, spot problems (e.g. underemployment in primary), and plan policy accordingly.
Q7. Why focus on employment and GVA? Other issues? Employment and GVA show an economy's size and how it shares work. But other issues matter too — quality of jobs, fair wages, working conditions, security, and whether growth is environmentally sustainable and reaches the poor.
Q8. List kinds of work adults do and classify them. Example: farmer → primary; tailor, carpenter → secondary; shopkeeper, teacher, driver → tertiary. (Open answer; classify by nature of activity, or by organised/unorganised, or public/private.)
Q9. How is the tertiary sector different? Unlike primary and secondary, it does not produce a good; it provides services that support production and people — e.g. transport, banking, communication, trade, teaching, IT.
Q10. Disguised unemployment with urban & rural examples. It is hidden underemployment where people appear to work but contribute little. Rural: all five members of Laxmi's family work a small plot though two would suffice. Urban: a street vendor or repair person who spends the whole day but earns very little for want of better work.
Q11. Open vs disguised unemployment. In open unemployment a person has no job at all and is clearly visible as jobless. In disguised unemployment people appear employed but more are working than needed, so part of their labour is wasted.
Q12. "Tertiary sector plays no significant role" — agree? Disagree. It is now the largest contributor to India's GVA, provides essential basic services (health, education, transport, banking), supports the other two sectors, and IT-based services drive rapid growth.
Q13. Two kinds of people the service sector employs. (a) A small number of highly skilled, well-paid workers; (b) a large number of low-paid workers (small shopkeepers, repair persons, transport persons) who barely earn a living.
Q14. Are unorganised workers exploited? Yes. They are paid low and irregular wages, get no paid leave or benefits, work long hours, have no job security and can be removed anytime — they need protection.
Q15. How are activities classified by employment conditions? Into organised (regular terms, registered, follow rules, secure, with benefits) and unorganised (scattered units outside government control, insecure, low-paid, no benefits).
Q16. Compare employment in organised & unorganised sectors. Organised: fixed hours, assured salary, paid overtime, leave, PF, gratuity, medical benefits, pension, job security. Unorganised: long hours, low and irregular pay, no benefits, no security. (See §9 table.)
Q17. Objective of MGNREGA 2005 / Viksit Bharat–G RAM G 2025. To guarantee 100 days of wage employment a year to every rural household whose adult members are willing to do unskilled manual work — providing the "Right to Work", reducing rural underemployment, and creating assets that raise future production.
Q18. Compare private and public sector activities (examples from your area). Private (a local shop, a private hospital) aims at profit; public (the government school, the post office, the panchayat water supply) aims at public welfare even at a loss. (Open answer.)
Q19. Well-managed vs badly-managed (public & private). Open answer with one local example each — e.g. a clean, punctual government hospital (well-managed public) vs a poorly-run government office; a reliable private firm vs a cheating private trader.
Q20. Public sector activities & why government took them up. Railways, post, defence, dams/irrigation, electricity, roads, schools, hospitals, PDS ration shops — because they need huge investment, must reach everyone at reasonable cost, or are the government's basic responsibility (health, education, welfare of the poor).
Q21. How public sector aids economic development. It builds costly infrastructure (roads, power, railways), supplies essentials cheaply, buys crops at fair prices, provides health and education, supports private industry, and looks after the poorest regions — all of which help the whole economy grow.
Q22. Unorganised workers need protection on wages, safety, health — with examples. Wages: a daily-wage labourer paid below minimum wage needs wage protection. Safety: a construction worker without safety gear risks injury. Health: a rag-picker or factory worker exposed to dust/chemicals needs medical cover.
Q23. Ahmedabad data as a table. Of 15,00,000 workers, 11,00,000 (about 73%) were in the unorganised sector and 4,00,000 (about 27%) in the organised sector. Of Rs 60,000 million total income, Rs 32,000 million (about 53%) came from the organised sector and Rs 28,000 million (about 47%) from the unorganised sector — so most workers (unorganised) earn a smaller share of income. Ways to create more jobs: support small-scale and unorganised units with credit, raw material and marketing; train workers; promote local industry, tourism and services.
Q24. GVA share calculation. Total GVA = Primary + Secondary + Tertiary. For 2001–02: total = 13,23,000 + 10,40,000 + 19,31,000 = 42,94,000 → Primary ≈ 31%, Secondary ≈ 24%, Tertiary ≈ 45%. For 2021–22: total = 24,79,400 + 40,73,000 + 73,25,000 = 1,38,77,400 → Primary ≈ 18%, Secondary ≈ 29%, Tertiary ≈ 53%. Conclusion: the primary share fell while the tertiary share rose and stayed the largest — confirming the rising importance of the service sector.
13. Common confusions
- GDP vs GVA: GDP counts final goods and services; GVA is each sector's contribution after adjusting taxes and subsidies. For this class, both show the same trend.
- Final vs intermediate goods: only final goods are counted in GDP; counting intermediate goods (wheat, flour) too would mean double counting.
- Largest producer vs largest employer: in India the tertiary sector produces the most, but the primary sector employs the most.
- Underemployment vs unemployment: the underemployed appear to work but below potential (disguised); the unemployed have no work at all (open).
- Organised vs public: "organised/unorganised" is about conditions of work; "public/private" is about ownership — a private company can be organised.
- Tertiary ≠ unimportant: services support all production and now lead India's GVA.
14. Quick revision checklist
- Three classifications: nature (primary/secondary/tertiary), work conditions (organised/unorganised), ownership (public/private).
- Primary = natural goods; secondary = manufacturing; tertiary = services that support the rest.
- GDP = value of all final goods and services produced within a country in a year.
- India: tertiary = largest producer; primary = largest employer → underemployment / disguised unemployment.
- Organised = secure + benefits; unorganised = insecure, low-paid, >90% of workers, needs protection.
- Public = government-owned, welfare motive; private = profit motive.
- MGNREGA 2005 = 100 days guaranteed rural work = Right to Work (now Viksit Bharat–G RAM G 2025).
