Primary, Secondary & Tertiary Sectors
Sectors of the Indian Economy
What you'll learn
- Distinguish between primary, secondary, and tertiary sectors.
- Understand how these sectors are interconnected.
- Analyse employment and output share in each sector.
- Explain the concept of organised vs unorganised sectors.
Key concepts
Three Sectors of Economic Activity
| Sector | Activities | Examples |
|---|---|---|
| Primary | Extracts natural resources | Farming, fishing, forestry, mining |
| Secondary | Processes raw materials into goods | Manufacturing, construction, electricity |
| Tertiary | Provides services | Banking, transport, trade, education, healthcare |
Also called Agriculture, Industry, and Services sectors respectively.
How They Are Linked
- Primary sector produces raw materials → Secondary sector processes them → Tertiary sector delivers them.
- Example: Cotton (primary) → Textile factory (secondary) → Retail shop (tertiary).
Contribution to GDP
- GDP (Gross Domestic Product) = total value of goods and services produced.
- Services sector now contributes the largest share of India's GDP (~55%).
- Agriculture employs the most workers but contributes less to GDP (~15-18%).
| Sector | % of GDP (approx.) | % of Employment (approx.) |
|---|---|---|
| Primary | 15–18% | ~44% |
| Secondary | 25–27% | ~25% |
| Tertiary | 55–60% | ~31% |
Historical Shift
- In 1947: Most workers in agriculture (primary sector).
- Over time: Workers moved to secondary and tertiary sectors (structural transformation).
- In developed countries, tertiary sector dominates both GDP and employment.
Organised vs Unorganised Sector
| Feature | Organised | Unorganised |
|---|---|---|
| Registration | Registered with govt | Not registered |
| Job security | High (contracts) | Low (daily wages) |
| Social benefits | Provident fund, ESI | Rarely provided |
| Examples | Government offices, large factories | Street vendors, domestic workers |
Public vs Private Sector
| Feature | Public Sector | Private Sector |
|---|---|---|
| Ownership | Government | Private individuals/companies |
| Aim | Public welfare | Profit |
| Examples | Railways, ONGC, post office | Reliance, Tata, local shops |
Why Primary Sector Employs Most Workers
- Low skills barrier — most rural population works in farming.
- Disguised unemployment: Many workers share the same task; removing some wouldn't reduce output.
- Low productivity per worker → poverty cycle.
Solutions to Improve Employment
- Invest in rural infrastructure (roads, irrigation) to boost farm productivity.
- MGNREGS (Mahatma Gandhi National Rural Employment Guarantee Scheme) — 100 days guaranteed work.
- Develop small and medium enterprises (SMEs) in secondary sector.
- Expand education and healthcare to create skilled tertiary sector jobs.
