Sectors of the Indian Economy

This is Chapter 2 of the Class 10 book Understanding Economic Development: 19 pages (19–37), with a page of notes for teachers (p. 18). It has five headed parts — sectors of economic activities; comparing the three sectors; primary, secondary and tertiary sectors in India (with ‘how to create more employment’); organised and unorganised sectors; public and private sectors — with three graphs, four tables (2.1–2.4), a boxed story (Kanta and Kamal), six ‘Let's work these out’ boxes, a ‘Let's recall’ box, photographs and drawings, and 24 exercise questions. The graphs' bars carry no printed values except Graph 3's, so we read them off and say so; every derived number is recomputed; each figure's year is given; slips are flagged.

• Builds on jess201 (Development — income and public facilities) and leads into jess203 (Money and Credit — Laxmi's need for cheap credit), jess204 (Globalisation — the new IT services) and jess205 (Consumer Rights).
• Pairs with Indian Economic Development (keec1): keec106 (Employment: growth, informalisation — the same story with fuller data), keec105 (Rural Development — credit, MGNREGA), keec103 (Liberalisation — public sector and disinvestment), keec102 (the public sector's place in 1950–90 planning); and Introductory Macroeconomics (leec1): leec102 (National Income Accounting — final vs intermediate goods, value added, GDP and GVA).
• Geography and sociology: Fundamentals of Human Geography legy104 (Primary), legy105 (Secondary) and legy106 (Tertiary and Quaternary Activities); Social Change and Development in India lesy205 (Change and Development in Industrial Society — formal and informal work).
• UPSC, honestly: the ideas here — the rising share of services (Prelims 1991, 1999), disguised unemployment (1992, 2013), who can use the rural employment guarantee (2011) — recur in Prelims, and GS3 has asked why India moved from agriculture straight to services (2014), about ‘jobless growth’ (2015) and informalisation (2016). We link eight. Most other economy questions on these topics test the fuller keec106 and leec102 material.

• Three classifications, three questions: primary/secondary/tertiary by nature of activity; organised/unorganised by conditions of employment; public/private by ownership.
• Count only final goods (biscuits ₹80, not wheat + flour + biscuits = ₹125). Sum over sectors = GDP; India now reports each sector's GVA.
• 1977–78 → 2017–18: services became the largest producing sector (≈30% → ≈53% of GVA, read off Graph 2); agriculture fell from ≈48% to ≈19%.
• But jobs lagged: the primary sector still had 44% of workers in 2017–18 (71% in 1977–78) — underemployment / disguised unemployment: more people than the work needs.
• Creating jobs: irrigation, roads and storage, cheap credit, agro-industry in semi-rural areas, education, health, tourism; short term: MGNREGA 2005 (100 days a year, unemployment allowance) — replaced in 2025 by Viksit Bharat-G RAM G, says the reprint.
• Table 2.3: 82 of 475 million workers organised (17%), 83% unorganised, 99.6% in agriculture. The public sector exists for what private firms won't provide at a reasonable cost.

Primary sector: activities that produce a good by directly using natural resources. Cotton grows within a crop season and depends ‘mainly, but not entirely’ on rainfall, sunshine and climate; milk depends on animals' biology and fodder; minerals and ores are natural products too. It is called primary because it forms the base for all other products; since most natural products come from agriculture, dairy, fishing and forestry, it is also called the agriculture and related sector.

Secondary sector: natural products are changed into other forms through manufacturing — in a factory, a workshop or at home. Cotton fibre becomes yarn and cloth; sugarcane becomes sugar or gur; earth becomes bricks, and bricks houses. Because it came to be associated with industries, it is also called the industrial sector. Tertiary sector: activities that help the development of the other two — transport, storage, communication, banking, trade — and that by themselves produce services, not goods; hence the service sector. It also includes services that don't directly help produce goods: teachers, doctors, washermen, barbers, cobblers, lawyers, administrative and accounting work, and newer IT-based services such as internet cafés, ATM booths, call centres and software companies.

Interdependence. Though grouped separately, the three are highly interdependent. Table 2.1 gives four cases and fills in only the first: if farmers refuse to sell sugarcane to a mill, the mill shuts — the secondary sector depends on the primary. The other three, completed: if mills stop buying Indian cotton and import it, cotton prices fall and farmers may go bankrupt — the primary depends on the secondary as a buyer; if fertiliser or pumpset prices rise, farm costs rise and profits fall — the primary depends on the secondary as a supplier; if transporters strike, food grows scarce in towns and farmers can't sell — both depend on the tertiary sector.

You can't add cars, computers, nails and furniture, so we add their values. NCERT's examples: 10,000 kg of wheat at ₹20 a kg is worth ₹2,00,000; 5,000 coconuts at ₹15 each are worth ₹75,000 (both checked). But only final goods and services are counted. A farmer sells wheat to a flour mill at ₹20 a kg; the mill sells flour to a biscuit company at ₹25 a kg; the company adds sugar and oil and sells four packets of biscuits for ₹80 (₹20 a packet). Wheat and flour are intermediate goods — used up in making the final good — and the ₹80 already includes them. Adding wheat, flour and biscuits (₹20 + ₹25 + ₹80 = ₹125) would count the same wheat three times.

The value of final goods and services produced in a sector in a year is that sector's total production; the sum over all sectors is the Gross Domestic Product (GDP) — the value of all final goods and services produced within a country during a particular year. GDP shows how big the economy is. In India a central government ministry (with state and union-territory departments) collects quantities and prices and estimates it. Recently the government began reporting each sector's contribution to Gross Value Added (GVA) instead of to GDP, ‘to be at par with global practices’; GVA is measured after adjusting for taxes and subsidies (you meet the difference in Class 12).

History of developed countries: at first the primary sector dominated both production and employment. Better farming produced surplus food, so more people became craftspeople, traders, transporters, administrators and soldiers. Over more than a hundred years, new manufacturing methods brought factories; people moved — ‘were forced to’, NCERT notes — from farms to factories, and the secondary sector became the most important in both production and employment. In the past 100 years a further shift took place to the tertiary sector, now the largest in production and in jobs.

India, 1977–78 to 2017–18 (Graph 1, real GVA at 2011–12 prices; the book chose these two years because the data are ‘comparable and authentic’). Production rose in all three sectors but most in the tertiary sector, which replaced the primary sector as the largest producer. Reading the bars (they carry no values): total GVA grew from about ₹15 lakh crore to about ₹122 lakh crore — roughly 8 times; in 2017–18 primary ≈ ₹22, secondary ≈ ₹35 and tertiary ≈ ₹65 lakh crore. Graph 2 gives shares: primary ≈ 48% → 19%, secondary ≈ 22% → 28%, tertiary ≈ 30% → 53%. Applying Graph 2's shares to Graph 1's totals, secondary output rose about 10 times and tertiary about 14 times — matching the text's ‘more than nine times’ and ‘14 times’; primary output rose about 3 times.

Graph 3 shows the share of employment: in 1977–78 primary 71%, secondary 11%, tertiary 18%; in 2017–18 primary 44%, secondary 25%, tertiary 31% (both add to 100 — checked). While output moved sharply out of agriculture, jobs did not follow: the primary sector is still the largest employer. Why? Not enough jobs were created in industry and services. NCERT: industrial output rose more than nine times but industrial employment only about three times; service output rose 14 times but service employment about five times. So in 2017–18 the primary sector held 44% of workers but produced only about 19% of GVA — a primary worker produced well under half (0.43) of the average worker's output, against 1.12 in industry and 1.71 in services (GVA share ÷ jobs share, our arithmetic).

Underemployment. There are more people in agriculture than the work needs; move a few out and production won't fall. NCERT's example: Laxmi, a small farmer with about two hectares of unirrigated, rain-fed land growing jowar and arhar. All five family members work on the plot all year because they have nowhere else to go; their labour effort is divided — everyone works, no one is fully employed. This is underemployment, where people work less than their potential; since it is hidden, unlike someone visibly without a job, it is also called disguised unemployment. If a landlord, Sukhram, hires one or two of them, or two move to a factory, the family earns extra wages while the plot produces as much as before. There are lakhs of farmers like Laxmi. Underemployment exists in services too: urban casual workers — painters, plumbers, repair persons — who don't find work every day, and street vendors who spend the whole day earning very little because they have no better options.

In and around agriculture: (1) irrigation — a well funded by government or a bank loan lets Laxmi grow a second, rabi crop of wheat; if one hectare of wheat employs two people for 50 days (sowing, watering, fertiliser, harvesting), two more family members find work on her own field — on all her 2 hectares that would be up to 200 person-days (our arithmetic); a dam and canals could do this for many farms. (2) Transport and storage — rural roads and storage let farmers sell the extra crop and employ transporters and traders. (3) Cheap credit — seeds, fertiliser, equipment and pumpsets bought on time from a bank at a reasonable rate, instead of a moneylender at a high one (Chapter 3). (4) Industries and services in semi-rural areas — a dal mill for arhar and chickpea, cold storage for potatoes and onions, honey collection centres near forests, processing of vegetables, fruit and grain.

Education, health and tourism: NCERT says about 60% of India's population is aged 5–29 and only about 51% of them attend educational institutions; more schools need more buildings, teachers and staff — a study by the erstwhile Planning Commission (now NITI Aayog) estimated nearly 20 lakh jobs in education alone. Better health needs many more doctors, nurses and health workers in rural areas. The same study says improving tourism could give more than 35 lakh people additional jobs every year. Each region has its own potential: tourism, regional crafts, IT.

Quick measures — the Right to Work. Long-term plans take time, so the Union Government made a law implementing the Right to Work in about 625 districts: the Mahatma Gandhi National Rural Employment Guarantee Act 2005 (MGNREGA 2005). All who are able to, and in need of, work in rural areas were guaranteed 100 days of employment a year by the government; if the government failed, it would pay an unemployment allowance; work that would raise future production from land got preference. The 2026–27 reprint adds: ‘In 2025, this Act was replaced by Viksit Bharat-Guarantee for Rozgar and Ajeevika Mission (Viksit Bharat-G RAM G 2025).’

This classification looks at conditions of employment. In the boxed story, Kanta works in an office from 9.30 a.m. to 5.30 p.m. (8 hours), is paid monthly, gets provident fund, medical and other allowances, a paid Sunday, and had an appointment letter stating her terms. Kamal, her neighbour, is a daily-wage labourer in a grocery shop from 7.30 a.m. to 8 p.m. (12½ hours, our arithmetic), with no allowances, no pay for days off, no leave or paid holidays, no letter, and can be asked to leave any time.

Kanta is in the organised sector: enterprises or places of work with regular terms and assured work, registered by the government and following its rules under laws such as the Factories Act, Minimum Wages Act, Payment of Gratuity Act and Shops and Establishments Act. Even the self-employed can be organised if they register and follow the rules. Organised workers have job security, fixed hours, overtime pay, paid leave and holidays, provident fund, gratuity, medical benefits, safe drinking water and a safe workplace by law, and pensions on retirement. Kamal is in the unorganised sector: small, scattered units largely outside government control; rules exist but are not followed; jobs are low-paid and irregular; no overtime, paid leave, holidays or sick leave; workers can be dismissed without reason, or laid off in slack seasons, at the employer's whim. It includes many self-employed people — street sellers, repair workers — and farmers who hire labour as needed.

Table 2.3 (estimated workers in millions, ‘late 1990s’): organised 1, 41 and 40 in primary, secondary and tertiary (total 82); unorganised 74 and 88 in secondary and tertiary; totals 232, 115 and 128. Filling the blanks: unorganised primary = 232 − 1 = 231; unorganised total = 393; grand total = 475. So 99.6% of primary-sector workers are unorganised; across the country 82.7% (‘about 83%’) of workers are in the unorganised sector and only 17.3% (‘about 17%’) have organised-sector jobs. Agriculture is an unorganised activity because almost all farmers and farm labourers work without registration, contracts or benefits.

Organised jobs are the most sought-after, but they have grown very slowly. Many organised enterprises operate as unorganised ones to evade taxes and avoid labour laws, so workers are pushed into low-paid, insecure, benefit-less jobs where they are often exploited and not paid a fair wage. Since the 1990s many workers have also lost organised-sector jobs and taken unorganised ones with low earnings. Hence the need is not only for more work but for protection and support.

The third classification is by who owns the assets and delivers the services. In the public sector the government owns most assets and provides the services (railways, the post office); in the private sector individuals or companies do (NCERT names Tata Iron and Steel Company — TISCO — and Reliance Industries — RIL). Private activity is guided by profit; the public sector's purpose is not just profit, and governments fund it through taxes and other means.

NCERT stresses the duty to run proper schools, especially for elementary education (India's illiterate population is one of the largest in the world), and to act on health: it says nearly half of India's children are malnourished and a quarter critically ill, and that the infant mortality rates of Odisha (36) and Madhya Pradesh (43) are higher than those of some of the poorest regions of the world.

Numbers

One-liners

• Primary/secondary/tertiary: by the nature of the activity.
• Organised/unorganised: by conditions of employment.
• Public/private: by ownership of assets.
• Count only final goods — intermediate goods are already inside them.
• Services now produce the most; agriculture still employs the most.
• Disguised unemployment: everyone works, but some could leave without output falling.
• Not enough jobs were created in industry and services.
• MGNREGA made work a legal right — 100 days or an allowance.
• About five in six workers in the book's table are unorganised.
• The public sector provides what private firms won't at a reasonable cost.

Traps to avoid

• The text's ‘more than half of workers in the primary sector’ conflicts with Graph 3's 44% (2017–18).
• Graph 3's bar heights don't match its printed labels — quote the labels.
• Graphs 1 and 2 print no values: any number from them is approximate.
• Graph 1 shows GVA, though Q4 asks for ‘GDP’.
• ‘Thirty years’ in Summing up vs forty years in the graphs.
• Table 2.3's ‘late 1990s’ date is doubtful: its split matches 2011–12 data.
• Exercise 24 says ‘2000 and 2013’ and ‘GDP’; the data are GVA for 2001-02 and 2021-22.
• MGNREGA is a legal, not a fundamental, right — for every rural household, not only BPL.
• ‘80% of rural households are small and marginal farmers’: official data count holdings (86.1%), not households.
• Mining is primary in NCERT but usually ‘industry’ in India's national accounts.

Prelims — what UPSC asks

• Structural change: as GNP rises the tertiary share rises (1991); India's tertiary share has risen since 1980 (1999).
• Disguised unemployment = marginal productivity of labour zero (2013); among its rural causes, population pressure with half-hearted agrarian reform (1992, the official key — the chapter's own reason is ‘nowhere else to go’). MGNREGA: adult members of any rural household (2011).
• Also expect: final vs intermediate goods and GVA (see leec102), sector of an occupation, organised vs unorganised, NCEUS, e-Shram, the Labour Codes, PLFS.

Mains — where it appears and how to answer

• GS3: why India went from agriculture straight to services and whether it can develop without industry (2014); ‘jobless growth’ (2015); globalisation and informalisation (2016). Use Graphs 2–3 (19% of GVA, 44% of jobs), the output-per-worker gap, Laxmi for disguised unemployment, Table 2.3 for informality — with each figure's year.
• Set positions side by side — services-led vs manufacturing-led growth; informality as exclusion vs escape from costly rules; the rural employment guarantee's supporters and critics; a large vs a strategic public sector — and give laws and schemes as dated facts. No present-day political commentary.
