Chapter 2: Sectors of the Indian Economy
Complete exam-ready notes covering all three sector classifications, GDP/GVA, disguised unemployment, MGNREGA, organised/unorganised, public/private sectors — with UPSC-standard MCQs.
1. Sectors of Economic Activities — Introduction
Economic activities can be classified using several criteria. The NCERT chapter discusses three types of classification:
These groups are called sectors. Though grouped into three categories, all economic activities are highly interdependent.
2. Primary, Secondary and Tertiary Sectors
🌾 Primary Sector
Also called: Agriculture and Related Sector
- Activities undertaken by directly using natural resources
- Products are natural products
- Depends mainly (not entirely) on natural factors: rainfall, sunshine, climate
- Forms the base for all other products
Examples: Agriculture, dairy, fishing, forestry, mining, minerals & ores
🏭 Secondary Sector
Also called: Industrial Sector
- Natural products are changed into other forms through manufacturing
- Product is NOT produced by nature — manufacturing is essential
- Can be in factory, workshop, or at home
- Next step after primary
Examples: Cotton → yarn → cloth; sugarcane → sugar/gur; earth → bricks → houses
🚌 Tertiary Sector
Also called: Service Sector
- Activities that help in the development of primary and secondary sectors
- Do NOT produce a good by themselves — provide aid/support
- Generate services rather than goods
- Also includes essential services not directly linked to production
Examples: Transport, storage, communication, banking, trade, teachers, doctors, IT/software, ATM, call centres
| Example | What This Shows |
|---|---|
| Farmers refuse to sell sugarcane → sugar mill shuts down | Secondary/Industrial sector is dependent on Primary sector |
| Companies import cotton → Indian cotton farmers go bankrupt, prices fall | Primary sector is dependent on Secondary/global markets |
| Price of fertilisers/pumpsets rises → cost of cultivation rises, profits fall | Primary sector is dependent on Secondary sector inputs |
| Transporters’ strike → food scarce in cities, farmers cannot sell | Primary and Secondary sectors are dependent on Tertiary (transport) sector |
| Primary Sector | Secondary Sector | Tertiary Sector |
|---|---|---|
| Flower cultivator, Fishermen, Bee-keeper, Gardener | Basket weaver, Potter, Workers in match factory, Tailor | Milk vendor, Priest, Courier, Moneylender, Astronaut, Call centre employee |
Note: Astronaut and Priest are tertiary as they provide services and do not produce goods through natural or manufacturing processes.
3. Comparing the Three Sectors — GDP and GVA
How to Count Total Production?
Since we cannot add up physically different goods (cars + nails + wheat), economists use values (money terms) rather than numbers. Example: 10,000 kg wheat @ ₹20/kg = ₹2,00,000; 5,000 coconuts @ ₹15 = ₹75,000.
| Stage | Product | Value | Type |
|---|---|---|---|
| Farmer → Flour Mill | Wheat | ₹20/kg | Intermediate Good |
| Flour Mill → Biscuit Company | Flour | ₹25/kg | Intermediate Good |
| Biscuit Company → Consumer | Biscuits (4 packets) | ₹80 (₹20/packet) | Final Good ✓ |
Only Final Goods and Services are counted in GDP. Intermediate goods are used up in producing final goods — their value is already included in the final good’s price. Counting them separately would mean double counting.
GDP = Sum of value of all final goods and services produced within a country during a particular year.
GDP shows how big the economy is. In India, measuring GDP is undertaken by a central government ministry with help from government departments of all states and union territories — collecting data on total volume of goods/services and their prices.
Indian Government recently shifted to reporting Gross Value Added (GVA) by the three sectors — to be at par with global practices.
GVA = Measures the contribution of three sectors after adjusting for taxes and subsidies.
Relation: GDP = GVA + Taxes on products − Subsidies on products
The GVA data in this chapter is at 2011–12 prices (Real GVA at Basic Prices). Source: Economic Survey.
4. Historical Change in Sectors
| Stage / Era | Dominant Sector | Key Change |
|---|---|---|
| Initial stage of development | Primary (Agriculture) | Most goods were natural products; most people employed in agriculture |
| Industrial Revolution (100+ years) | Secondary (Industry) | New manufacturing methods; factories expanded; farm workers moved to factories; goods became cheaper |
| Past 100 years (developed countries) | Tertiary (Services) | Service sector became most important in production; most working people employed in services |
This is the general pattern observed for developed countries.
5. Primary, Secondary and Tertiary Sectors in India (1977–78 to 2017–18)
- Data compared for 1977–78 and 2017–18 (comparable and authentic data).
- In 1977–78: Primary sector was the largest producing sector.
- In 2017–18: Tertiary sector has emerged as the largest producing sector, replacing primary.
- Production increased in all three sectors, but most in the tertiary sector over forty years.
- India’s GDP in 2017–18 was approximately ₹1.4 crore crore (₹140 lakh crore).
Why is the Tertiary Sector Becoming Important in India?
- Basic Services: Essential services like hospitals, schools, post/telegraph, police, courts, municipal corporations, defence, transport, banks, insurance — the government must provide these in a developing country.
- Derived Demand from Other Sectors: Development of agriculture and industry leads to demand for transport, trade, storage. Greater primary/secondary development → more demand for services.
- Rising Incomes: As incomes rise, people demand more services — eating out, tourism, shopping, private hospitals, private schools, professional training — especially visible in big cities.
- IT and ICT Services: Over the past decade, services based on information and communication technology have become important and essential, with rapidly rising production.
The service sector in India has two very different groups:
- High-skill end: Limited number of services employing highly skilled and educated workers (IT, finance, legal, medical professionals).
- Low-skill, low-income end: Very large number of workers — small shopkeepers, repair persons, transport persons — who barely manage to earn a living and perform these services because no alternative opportunities are available.
Hence, only a part of the service sector is truly growing in importance.
6. Employment and the Mismatch with GVA
| Sector | Share in Employment 1977–78 | Share in Employment 2017–18 | Trend in GVA |
|---|---|---|---|
| Primary | 71% | 44% | Share declined but still significant |
| Secondary | 11% | 25% | Share increased |
| Tertiary | 18% | 31% | Largest share in GVA |
A remarkable fact about India: While there has been a change in the share of three sectors in GVA, a similar shift has NOT taken place in employment.
- The primary sector continues to be the largest employer even in 2017–18 (44% of employment).
- Industrial output rose by more than 9 times during the period, but employment in industry rose only about 3 times.
- Production in the service sector rose by 14 times, but employment in services rose only around 5 times.
- Result: More than half the workers work in primary sector, producing only about one-sixth of GVA.
- Secondary and tertiary produce the rest of GVA but employ less than half the people.
7. Underemployment / Disguised Unemployment
Underemployment = When people are apparently working but are made to work less than their potential. Everyone appears employed, but their labour effort is divided.
This is hidden (unlike open unemployment which is clearly visible). Hence it is also called Disguised Unemployment.
Small farmer Laxmi owns about 2 hectares of unirrigated land, dependent only on rain, growing crops like jowar and arhar. All 5 members of her family work in the plot throughout the year.
Why? “They have nowhere else to go for work.”
Everyone is working, none is idle — but in fact, their labour effort gets divided. Each does some work but no one is fully employed. If 2 members leave for a factory, production on the farm does not fall — because only 3 are needed. Those 2 leaving earn wages + the family still produces as much from the land. Total income increases.
There are lakhs of farmers like Laxmi in India. This is why even removing many people from agriculture would not hurt agricultural production.
Thousands of casual workers in the service sector in urban areas search for daily employment. Employed as painters, plumbers, repair persons, odd-job workers — many don’t find work every day. Similarly, people on the street pushing a cart or selling something may spend the whole day but earn very little — doing this because they have no better opportunities.
| Feature | Open (Visible) Unemployment | Disguised Unemployment |
|---|---|---|
| Visibility | Clearly visible | Hidden |
| Employment status | Person has NO job | Person appears employed |
| Productivity | Zero output | Output does not fall if person leaves |
| Typical location | Urban areas mainly | Predominantly agricultural/rural |
| Example | Fresh graduate searching for job | 5 family members on 2-hectare farm where 2 suffice |
8. How to Create More Employment?
- Irrigation infrastructure: Government/banks investing in wells, canals, dams → farmers take a second crop (e.g., rabi wheat) → more employment within agriculture. (1 hectare wheat provides 2 people employment for 50 days.)
- Rural roads and transport: Better rural roads → mini-trucks reach everywhere → farmers like Laxmi can sell crops → employment in transport and trade.
- Agricultural credit: Local bank credit at reasonable interest → farmers buy seeds, fertilisers, equipment → better cultivation → no need for exploitative moneylenders.
- Agro-based industries in semi-rural areas: Dal mills, cold storage (potatoes/onions), honey collection centres, food processing units → employment near villages.
- Education sector: Nearly 20 lakh jobs can be created in education alone (erstwhile Planning Commission/NITI Aayog estimate). More schools → more teachers, staff, buildings.
- Health sector: More doctors, nurses, health workers needed in rural areas.
- Tourism: If tourism is improved, more than 35 lakh additional people can get employment every year (Planning Commission study).
- IT and regional crafts: Every state/region has potential — IT, regional craft industries, new services.
| Feature | Details |
|---|---|
| Full name | Mahatma Gandhi National Rural Employment Guarantee Act 2005 (MGNREGA 2005) |
| Nature | Legal right to work — “Right to Work” legislation |
| Coverage | Implemented in about 625 districts of India |
| Guarantee | 100 days of employment per year to all able and needy persons in rural areas |
| If govt. fails | Government provides unemployment allowances |
| Priority works | Works that increase production from land (dams, roads, irrigation, etc.) |
| Replaced by | In 2025, replaced by Viksit Bharat-Guarantee for Rozgar and Ajeevika Mission (Viksit Bharat-G RAM G 2025) |
About 60% of India’s population belongs to the age group 5–29 years. Out of this, only about 51% are attending educational institutions. The rest (particularly those under 18) may be at home or working as child labourers.
9. Division of Sectors as Organised and Unorganised
Classification based on conditions of employment — whether rules and regulations are followed.
✅ Organised Sector — Kanta
- Enterprises with regular terms of employment
- Registered by government; must follow rules and regulations
- Governed by: Factories Act, Minimum Wages Act, Payment of Gratuity Act, Shops and Establishments Act
- Has formal processes and procedures
- Fixed working hours; overtime paid
- Benefits: paid leave, provident fund, gratuity, medical benefits, pensions
- Safe working environment, drinking water
- Job security; appointment letter given
- Example: Kanta — office 9:30 am to 5:30 pm, regular salary, PF, Sunday holiday
❌ Unorganised Sector — Kamal
- Small and scattered units, largely outside government control
- Rules exist but are not followed
- Jobs are low-paid, often not regular
- No overtime, no paid leave, no holiday, no sickness leave
- Employment is not secure — can be asked to leave anytime
- No formal appointment letter
- Employer’s whims determine employment
- Includes street sellers, repair workers, farmers
- Example: Kamal — grocery shop 7:30 am to 8 pm, daily wages only, no formal contract
| Sector | Organised | Unorganised | Total |
|---|---|---|---|
| Primary | 1 | 231 | 232 |
| Secondary | 41 | 74 | 115 |
| Tertiary | 40 | 88 | 128 |
| Total | 82 | 393 | 475 |
| % of Total | ~17% | ~83% | 100% |
- Nearly 83% of workers in India are in the unorganised sector.
- Organised sector employment is available to only about 17% of workers.
- Agriculture (Primary) is almost entirely unorganised (231 out of 232 million).
Who Needs Protection — Unorganised Sector Workers?
Rural areas:
- Landless agricultural labourers
- Small and marginal farmers
- Sharecroppers
- Artisans (weavers, blacksmiths, carpenters, goldsmiths)
Nearly 80% of rural households in India are in the small and marginal farmer category — they need: seeds, agricultural inputs, credit, storage, marketing outlets.
Urban areas:
- Workers in small-scale industry
- Casual workers in construction, trade, transport
- Street vendors, head load workers, garment makers, rag pickers
Social dimension: Majority of workers from Scheduled Castes, Tribes, and Backward Communities are in the unorganised sector — they face both low/irregular pay AND social discrimination. Protection is necessary for both economic AND social development.
Since the 1990s, many organised sector enterprises operate in the unorganised sector — adopting strategies to evade taxes and refuse to follow labour protection laws. Workers are forced into unorganised sector jobs with very low, irregular earnings. Since the 1990s, a large number of organised sector workers have lost jobs and been forced into unorganised employment.
10. Sectors in Terms of Ownership: Public and Private
| Feature | Public Sector | Private Sector |
|---|---|---|
| Ownership | Government owns most assets | Private individuals or companies own assets |
| Delivery of services | Government provides all services | Private individuals/companies deliver services |
| Primary motive | Not just profit — social welfare, equity, development | Profit motive |
| Funding | Raises money through taxes and other sources | Earns through sale of goods/services |
| Examples | Railways, Post Office, MTNL, Air India, All India Radio | Tata Iron & Steel (TISCO), Reliance Industries (RIL), Jet Airways |
Why Does the Government Spend on Public Activities?
- Large capital needed, private sector cannot afford: Construction of roads, bridges, railways, harbours, generating electricity, irrigation through dams — require huge investment beyond private sector capacity. Also, collecting money from thousands of users is not easy. Even if private sector provides, they would charge a high rate.
- Government must support industries: Selling electricity at cost of generation would push up production costs. Many small-scale units might shut down. Government produces/supplies electricity at affordable rates, bearing part of the cost. Government also buys wheat and rice from farmers at ‘fair price’, stores in godowns, and sells to consumers at lower price through ration shops.
- Primary responsibility of government: Health and education for all — running proper schools, quality elementary education; addressing malnutrition (nearly half of India’s children are malnourished, a quarter critically ill); safe drinking water, housing for the poor, food and nutrition; taking care of poorest regions.
| Group | Odd One Out | Reason |
|---|---|---|
| Tourist guide, dhobi, tailor, potter | Potter | Potter produces goods (secondary); rest provide services (tertiary) |
| Teacher, doctor, vegetable vendor, lawyer | Vegetable vendor | Vendor deals in goods; rest are professional service providers |
| Postman, cobbler, soldier, police constable | Cobbler | Cobbler is in unorganised sector; rest are in organised/government service |
| MTNL, Indian Railways, Air India, Jet Airways, All India Radio | Jet Airways | Jet Airways is private sector; rest are public sector undertakings |
11. Share of Primary Sector in GDP and Employment (Table 2.2)
| Indicator | 1977–78 | 2017–18 |
|---|---|---|
| Share in GVA (Gross Value Added) | ~40%+ | ~15–18% |
| Share in Employment | ~71% | ~44% |
Over 40 years, the primary sector’s share in GVA has declined significantly, but its share in employment, while declining from 71% to 44%, still remains the highest. This means agriculture suffers from low productivity per worker — a key development challenge.
12. Surat Study — Organised vs Unorganised Workers (Exercise Q5)
| Place of Work | Nature of Employment | % of Workers |
|---|---|---|
| Offices and factories registered with government | Organised | 15% |
| Own shops/clinics in marketplaces with formal license | Organised | 15% |
| On the street, construction, domestic workers | Unorganised | 20% |
| Small workshops not registered with government | Unorganised | 50% |
| Total Unorganised Sector Workers | 70% | |
13. Ahmedabad Study — Exercise Q23
| Parameter | Organised Sector | Unorganised Sector | Total |
|---|---|---|---|
| Number of workers | 4,00,000 | 11,00,000 | 15,00,000 |
| % of workers | 26.7% | 73.3% | 100% |
| Income generated (₹ million, 1997–98) | ₹32,000 million | ₹28,000 million | ₹60,000 million |
| % of income | 53.3% | 46.7% | 100% |
The organised sector (26.7% of workers) generates more income (53.3%) than the unorganised sector (73.3% of workers generating only 46.7% of income). This confirms that unorganised sector workers are far less productive and far less paid than organised sector workers.
14. GVA Data — Exercise Q24
| Year | Primary (₹ Crores) | Secondary (₹ Crores) | Tertiary (₹ Crores) | Total GVA |
|---|---|---|---|---|
| 2001–02 | 13,23,000 | 10,40,000 | 19,31,000 | 42,94,000 |
| 2021–22 | 24,79,400 | 40,73,000 | 73,25,000 | 1,38,77,400 |
| Sector | 2001–02 (%) | 2021–22 (%) |
|---|---|---|
| Primary | ~30.8% | ~17.9% |
| Secondary | ~24.2% | ~29.3% |
| Tertiary | ~44.9% | ~52.8% |
Conclusion: Tertiary sector dominates and its share is increasing; Primary sector’s share is declining; Secondary sector’s share has grown moderately.
15. Problems of Farming Sector — Match the Following (Exercise Q3)
| Problem Faced by Farming Sector | Possible Measure / Solution |
|---|---|
| 1. Unirrigated land | (d) Construction of canals by the government |
| 2. Low prices for crops | (b) Cooperative marketing societies |
| 3. Debt burden | (e) Banks to provide credit with low interest |
| 4. No job in the off season | (a) Setting up agro-based mills |
| 5. Compelled to sell grains to local traders soon after harvest | (c) Procurement of food grains by government |
16. Summing Up (NCERT Summary)
| Classification | Criterion | Key Conclusion | Problem & Solution |
|---|---|---|---|
| Primary, Secondary, Tertiary | Nature of activity | Tertiary produces most of GVA; Primary employs most workers | Underemployment in agriculture → create more jobs in secondary & tertiary; develop rural areas |
| Organised, Unorganised | Conditions of employment / rule compliance | ~83% workers in unorganised; low wages, no security | Workers need protection, minimum wages, social security; laws to be enforced |
| Public, Private | Ownership of assets / delivery | Private sector works for profit; cannot provide all essential services | Government must spend on infrastructure, health, education, food security, poorest regions |

- (d) Share of tertiary sector in GVA in 2017–18: (iii) 50 to 60 per cent
18. UPSC Value Addition — Beyond NCERT
The shift from primary → secondary → tertiary as the dominant sector is called Structural Transformation. In India, this transformation is incomplete — the tertiary sector dominates GVA but the primary sector still dominates employment. This creates a productivity gap — agricultural workers produce far less per person than service sector workers.
This is a classic example of Lewis’s Dual Economy Model — a traditional subsistence sector (agriculture with surplus labour) coexisting with a modern capitalist sector (industry/services).
The NCERT chapter notes the rapid rise of IT-based services. In recent years, a new phenomenon — the Gig Economy — has emerged (Uber, Swiggy, Zomato workers, freelancers). These workers fall between organised and unorganised — they have digital contracts but lack traditional social security. This is a new policy challenge for India’s labour market.
- Factories Act: Safety, working conditions, hours of work in factories
- Minimum Wages Act: Sets minimum wages across sectors
- Payment of Gratuity Act: Gratuity for employees after 5 years of service
- Shops and Establishments Act: Regulates commercial establishments
- ESI Act (Employees’ State Insurance): Medical and cash benefits
- EPF Act (Employees’ Provident Fund): Retirement savings
- Labour Codes (2020): India consolidated 44 central labour laws into 4 Labour Codes — on Wages, Industrial Relations, Social Security, and Occupational Safety.
- Primary sector = Agriculture and related = Natural products
- Secondary = Industrial = Manufacturing (factory/workshop/home)
- Tertiary = Service = Aids other sectors; does not produce goods itself
- GDP = Value of all final goods and services produced within India in a year
- GVA = GDP adjusted for taxes and subsidies; India now uses GVA at Basic Prices
- In 2017–18: Tertiary = largest in GVA; Primary = largest in employment
- Disguised unemployment = also called hidden unemployment or underemployment
- MGNREGA 2005: 100 days guaranteed employment; 625 districts; replaced in 2025 by Viksit Bharat-G RAM G 2025
- ~80% of rural households = small and marginal farmers
- ~83% of workers = unorganised sector
- Planning Commission (now NITI Aayog): 20 lakh jobs in education; 35 lakh in tourism
- Organised sector employment = only ~17% of total workers (late 1990s data)
1. It is also called hidden unemployment.
2. It occurs when workers produce nothing — their marginal productivity is zero.
3. It is mainly found in agriculture and some urban service activities.
4. If some disguisedly unemployed workers leave, total output falls significantly.
