Sectors of the economy

Also called: Economic sectors, Sectoral classification, Sector · Topic: Sectors of the Indian Economy · NCERT: Class 6, Ch 14 "Economic Activities Around Us"; Class 10, Ch 2 "Sectors of the Indian Economy"; Class 11, Ch 4 "Presentation of Data"

Meaning

A sector of the economy is a group of economic activities that share one common criterion (a rule used for sorting). The Class 10 NCERT uses three criteria: nature of activity (primary, secondary, tertiary), employment conditions (organised, unorganised) and ownership of assets (public, private).

This matters because India has many kinds of livelihoods, from farming to software. Grouping them lets us see where output comes from, where people work and what policy each group needs. Output is measured as value added:

• GVA (Gross Value Added) = Value of output − Value of intermediate goods used up
• GDP = GVA + product taxes − product subsidies

Explanation

Why we classify, and what gets classified

• Only economic activity is sorted into sectors. Economic activity is any activity that creates monetary value (value that can be measured in money) and adds to GDP (the money value of all final goods and services produced inside a country in one year).
• A farmer selling wheat, a teacher earning a salary and a mechanic paid to repair a bike all count.

• Non-economic activity (a parent cooking for the family, volunteering, sevā such as the langar at a gurdwara) adds to well-being but falls outside GDP.

• Classification is an analytical tool. Class 10's "Let's Recall" calls it that.

• The right criterion depends on what we want to study. A school may group students by age or by class, depending on its purpose.

• Each lens leads to conclusions about production and jobs, and then to policy fixes.

• Kautilya's Arthashastra (quoted in the Class 6 chapter): "The root of prosperity is economic activity, the lack of it brings material distress."

The three lenses (Class 10, Table 2.4)

Classification	Criterion	What it shows
Primary / Secondary / Tertiary	Nature of activity	Services lead output, but agriculture still employs the most people → underemployment
Organised / Unorganised	Employment conditions	Most workers are unorganised and need protection
Public / Private	Ownership of assets	The state must provide infrastructure and basic services. Private firms follow profit

• Primary sector: uses natural resources directly (farming, fishing, mining).
• Secondary sector: turns natural products into other forms through manufacturing (cotton → cloth).
• Tertiary (service) sector: does not make goods itself but supports the other two (transport, banking, trade, IT).
• Organised sector: registered with the government. Jobs are regular, with fixed hours, paid leave and social security.
• Unorganised sector: small, scattered and mostly unregistered units. Jobs are low-paid, irregular and unprotected.
• Public sector: the government owns most of the assets (e.g. Railways).
• Private sector: individuals or companies own the assets. The main aim is profit.

Sectors are linked, not separate boxes

• The AMUL chain (Class 6):
• Farmers rear cattle and produce milk → primary
• The milk is processed into butter and milk powder → secondary
• The products are transported, stored, advertised and sold → tertiary

• If milk procurement stops, the other two sectors suffer as well.

• Value added avoids double counting. A farmer grows wheat worth ₹1,000. A baker turns it into bread worth ₹1,500.

• Farmer's value added = ₹1,000. Baker's value added = ₹1,500 − ₹1,000 = ₹500.
• Total GVA = ₹1,500. Adding ₹1,000 + ₹1,500 = ₹2,500 would count the wheat twice (double counting).
• Each sector's share of GDP and GVA is worked out this way.

Worked example: relative productivity

• Relative productivity = Sector's share of GVA ÷ Sector's share of workers (a rough measure)
• Agriculture: 17.7 ÷ 46.1 ≈ 0.38
• Services: 54.7 ÷ 29.7 ≈ 1.84

• On average, a services worker produces about 4.8 times (1.84 ÷ 0.38) as much value as a farm worker.

• What this means: too many people share too little farm output. This is underemployment (also called disguised unemployment: more people work on a job than it needs, so output does not fall if some leave).

• Caution: this calculation is only an illustration. The GVA figures cover April 2023–March 2024, and the PLFS figures cover July 2023–June 2024.

In India

• Output by sector: shares in GVA at current prices in FY24 (2023-24) were agriculture 17.7%, industry 27.6%, services 54.7% [2].

• The services share of GVA rose from 50.6% (FY14) to about 55% (FY25) [5].

• Jobs by sector: the PLFS (Periodic Labour Force Survey) was launched by the NSSO (MoSPI) in April 2017 [4]. Its figures for 2023-24:

• Agriculture 46.1%, up from 44.1% in 2017-18 [3]
• Manufacturing 11.4%, down from 12.1% [3]
• Services 29.7%, down from 31.1% [3]

• Among women workers, the share in agriculture rose from 57.0% (2017-18) to 64.4% (2023-24). Among men it fell from 40.2% to 36.3% [3].

• Employment conditions: how workers were employed, 2017-18 → 2023-24 [3]:

• Self-employed (running their own work, such as farmers or shopkeepers): 52.2% → 58.4%
• Regular wage/salaried (fixed monthly pay): 22.8% → 21.7%

• Casual labour (daily-wage work with no contract): 24.9% → 19.8%

• Headline labour rates (PLFS 2023-24, age 15+, usual status) [4]:

• LFPR (share of people working, or looking for and available for work) = 60.1%
• WPR (share of people who are employed) = 58.2%
• UR (share of the labour force with no work) = 3.2%. UR = (Unemployed ÷ Labour force) × 100.

• "Usual status" looks back 365 days. Current Weekly Status (CWS) looks back 7 days [4].

• e-Shram portal: launched by the Ministry of Labour and Employment on 26 August 2021. It builds the National Database of Unorganised Workers (NDUW). It had over 30.51 crore registrations by 31 December 2024 [3].

• It became a "One-Stop-Solution" on 21 October 2024, bringing different social-security schemes onto one portal [3].

Don't confuse with

• Number of workers employed: this is not a basis for dividing sectors. It is an outcome that we study through the three lenses. It is a common MCQ distractor.
• Organised sector vs public sector: "organised" is about employment conditions (registration, regular jobs, social security). "Public" is about ownership. A registered private company is in the organised sector and the private sector.
• Economic vs non-economic activity: the difference is payment or market value, not the kind of work. A cook paid by a hotel does economic activity. A mother cooking at home does non-economic activity, and it is outside GDP.
• Underemployment vs open unemployment: UR was only 3.2% (2023-24) [4], but that does not mean the jobs are good. The real problem is too many people sharing farm work, which is disguised unemployment, not people sitting idle.

Prelims Hooks

• The three Class 10 criteria are nature of activity, employment conditions and ownership of assets. "Number of workers" is not a criterion.
• GVA = Output − Intermediate consumption. GDP = GVA + product taxes − product subsidies.
• GVA shares in FY24 (current prices): agriculture 17.7%, industry 27.6%, services 54.7% [2].
• Agriculture's share of the workforce was 46.1% in PLFS 2023-24, up from 44.1% in 2017-18. Do not assume it keeps falling [3].
• 58.2% is the WPR in PLFS 2023-24, not agriculture's share of jobs. LFPR was 60.1% and UR was 3.2% [4]. PLFS is run by the NSSO (MoSPI) and began in April 2017 [4].
• e-Shram (Ministry of Labour and Employment, 26 August 2021) builds the NDUW. It had 30.51 crore registrations by 31 December 2024 [3].

Mains Points

• Output and jobs do not match across sectors. Services produce about 55% of GVA but employ about 30% of workers. Agriculture produces 17.7% of GVA but employs 46.1% of workers [2][3][5].
• Result: low income per farm worker and disguised unemployment.

• Policy link: labour-intensive manufacturing, food processing and rural non-farm jobs can move surplus workers out of farming.

• The farm share of workers has risen since 2017-18, especially among women (57.0% → 64.4%) [3]. It can be read two ways.

• Positive reading: more women are joining the labour force.
• Negative reading: there are not enough non-farm jobs, so workers are going back to farming.

• Use this debate in GS-III answers on employment and inclusive growth.

• Each lens points to a different policy.

• Sector lens → structural transformation (moving workers from low-output to high-output work).
• Organised/unorganised lens → labour protection and social security. With self-employment at 58.4% and casual labour at 19.8% [3], most workers have no social security. e-Shram's 30.51 crore registrations [3] show both how large the problem is and how the state is responding (GS-II: welfare schemes for vulnerable sections).
• Ownership lens → the government must provide infrastructure, health and education where profit-seeking firms will not invest.
