Sectors of the Economy

Prerequisites

• GDP, GNP and NNP: sector shares are shares of GVA at basic prices.
• Measurement of National Income: how sector GVA is estimated.

The Hook: Tendu Leaves, Steel Rails and a Bank Counter

Why it matters: Prelims asks which activity belongs to which sector, the definition of the unorganised sector and the broad sector shares of India. Mains P-V (GS-III) asks about structural transformation, jobless growth and the Chhattisgarh economy, where the contrast between output and employment is sharp.

Three (and More) Sectors by Activity

The quaternary and quinary categories are a geographers’ extension. In the national accounts, all services are in the tertiary sector.

How MoSPI groups GVA

India: Output vs Employment (dated)

Share in GVA

• The tertiary sector contributes more than half of India’s GVA.
• In the new series, the share of agriculture and allied activities was revised upward compared with the old 2011–12 series (about 18% in 2022–23, against about 16.5% in the old series).

Share in employment

• Agriculture remains the largest employer. The PLFS Annual Report 2025 (the first on a calendar-year basis, January to December 2025) puts agriculture’s share of workers at about 43% (usual status), lower than in earlier rounds.
• So agriculture provides roughly four in ten jobs but only about one-sixth to one-fifth of GVA. Output per worker in agriculture is therefore far below the average, which is the root of rural distress and disguised unemployment.

Chhattisgarh: An Industry-Heavy State with a Farm-Dependent Workforce

What this tells you:

1. Industry’s share is far higher than India’s. Chhattisgarh has large deposits of coal, iron ore, bauxite, limestone and dolomite, and it hosts big plants: Bhilai Steel Plant, thermal power at Korba, cement units around Raipur and Baloda Bazar. Mining and these industries are capital-intensive. See Minerals, Energy and Industries.
2. Services are smaller than the national average, though they are growing fastest.
3. Employment is the opposite of output. The largest share of the state’s workforce still depends on paddy farming (the state is called the “rice bowl” (धान का कटोरा)) and on forests (minor forest produce such as tendu leaves, mahua, sal seeds). See Agriculture and Irrigation.
4. Mains point: high GSDP from capital-intensive mining does not automatically mean many jobs or high incomes in the mining districts; it raises questions of displacement, environmental cost and benefit-sharing (for example, District Mineral Foundation funds).

Other Ways to Classify Sectors

By organisation: organised vs unorganised

Official definition (NCEUS): the National Commission for Enterprises in the Unorganised Sector (chair Arjun Sengupta) defined the unorganised sector as all unincorporated private enterprises owned by individuals or households, run on a proprietary or partnership basis, with fewer than ten total workers.

Informal employment is wider: even an organised company can employ workers informally (contract labour without social security). By most estimates, close to nine out of ten Indian workers are informally employed.

Policy response: the e-Shram portal (launched August 2021) to build a national database of unorganised workers; the labour codes extend social security to gig and platform workers.

By ownership: public vs private

India is a mixed economy (मिश्रित अर्थव्यवस्था): public and private sectors co-exist. Since 1991, the balance has shifted towards the private sector (see Industrial Policy and MSMEs). There are also joint (public-private partnership) and cooperative sectors.

Structural Transformation: Analysis for Mains

The classical pattern (Clark–Fisher hypothesis): as per capita income rises, the share of output and employment moves from primary → secondary → tertiary. Allan Fisher and Colin Clark described this sequence in the 1930s–40s; Simon Kuznets documented it across countries.

graph LR
    A["Primary
(farms, forests, mines)"] -->|"industrialisation"| B["Secondary
(factories, construction)"]
    B -->|"post-industrial shift"| C["Tertiary
(services)"]
    A -.->|"India's path:
services-led"| C

India’s deviation:

1. Services-led growth: India’s output share moved from agriculture mainly to services, skipping a large manufacturing phase. IT and business services became a growth engine.
2. Employment lag: labour did not move out of agriculture as fast as output did. Many who left farming went into construction and informal services, not factories.
3. “Premature deindustrialisation” (Dani Rodrik’s term): manufacturing’s share of output and jobs peaked at lower income levels than in earlier industrialisers.
4. Consequences: low productivity in agriculture, disguised unemployment, jobless or job-poor growth, rising informality.

Policy responses: Make in India and Production Linked Incentive (PLI) schemes for manufacturing; MSME support; skilling; agro-processing and food parks to create rural non-farm jobs. In Chhattisgarh, the industrial policy’s focus on value addition to minerals, forest produce and agriculture (e.g. food processing) follows the same logic. See Poverty, Unemployment and Inclusive Growth.
