Indian Economy: Basic Concepts — GDP, Sectors, RBI, Five Year Plans
Essential Indian economy notes for Kerala PSC — GDP, economic sectors, RBI functions, Five Year Plans, poverty line, and key institutions. Based on NCERT Class 9-10 Economics.
Indian Economy questions appear in every Kerala PSC paper — typically 3-5 questions. The questions are concept-based, not calculation-heavy. These notes cover the essential facts from NCERT Class 9 (Economics) and Class 10 (Understanding Economic Development) plus PSC-specific additions.
Three Sectors of the Economy
| Sector | Also called | Activities | Examples |
|---|---|---|---|
| Primary | Agriculture sector | Extraction of natural resources | Farming, fishing, mining, forestry |
| Secondary | Industrial sector | Manufacturing and processing | Factories, construction, power generation |
| Tertiary | Service sector | Services | Banking, transport, education, IT, healthcare |
Sector contribution to GDP (evolution)
| Period | Dominant sector |
|---|---|
| At Independence (1947) | Primary (agriculture ~55% of GDP) |
| 1970s-1990s | Secondary (industry growing) |
| Current (2020s) | Tertiary (services ~54% of GDP) |
PSC favourite: “Which sector contributes the most to India’s GDP currently?” — Tertiary/Service sector (~54%). But the sector that employs the most people is still the Primary/Agriculture sector (~42% of workforce). This mismatch is a key NCERT concept.
GDP and National Income
| Term | Meaning |
|---|---|
| GDP (Gross Domestic Product) | Total value of all goods and services produced within the country in a year |
| GNP (Gross National Product) | GDP + income earned by citizens abroad − income earned by foreigners within India |
| NNP (Net National Product) | GNP − Depreciation |
| Per Capita Income | National Income ÷ Population |
| Nominal GDP | GDP at current market prices |
| Real GDP | GDP adjusted for inflation (at constant prices) |
PSC distinction: GDP = within the country (territorial). GNP = by citizens (national). Real GDP is used for comparison across years because it removes the inflation effect.
Reserve Bank of India (RBI)
| Fact | Detail |
|---|---|
| Established | 1 April 1935 |
| Under which Act | RBI Act, 1934 |
| Nationalised | 1 January 1949 |
| Headquarters | Mumbai |
| First Governor | Sir Osborne Smith (British) |
| First Indian Governor | C.D. Deshmukh |
| Current Governor | Check current — changes frequently |
Functions of RBI
- Monetary authority — controls money supply through repo rate, reverse repo rate, CRR, SLR
- Banker to the Government — manages government accounts and debt
- Banker’s bank — lender of last resort for commercial banks
- Currency issuer — sole authority to issue currency notes (except ₹1 coin/note — issued by Ministry of Finance)
- Foreign exchange manager — manages forex reserves under FEMA
- Regulator of banking — supervises and regulates commercial banks
Key RBI rates
| Rate | What it means | Effect when raised |
|---|---|---|
| Repo Rate | Rate at which RBI lends to banks | Banks borrow less → less money in system → inflation controlled |
| Reverse Repo Rate | Rate at which RBI borrows from banks | Banks park more money with RBI → less lending → reduces inflation |
| CRR (Cash Reserve Ratio) | % of deposits banks must keep with RBI as cash | Less money available for lending |
| SLR (Statutory Liquidity Ratio) | % of deposits banks must keep in liquid assets (gold, govt securities) | Less money available for lending |
| Bank Rate | Rate for long-term lending by RBI to banks | Higher cost of funds for banks |
PSC staple: “₹1 note/coin is issued by whom?” — Ministry of Finance (signed by Finance Secretary). All other currency notes are issued by RBI (signed by RBI Governor).
Five Year Plans
India adopted Five Year Plans from 1951, inspired by the Soviet model. The Planning Commission (now NITI Aayog) was responsible.
Key Five Year Plans

Economic Reforms of 1991 (LPG)
India faced a balance of payments crisis in 1991. PM P.V. Narasimha Rao and FM Dr. Manmohan Singh introduced reforms:
LPG = Liberalisation, Privatisation, Globalisation
| Reform | Meaning |
|---|---|
| Liberalisation | Reducing government regulations, licensing, and controls on businesses |
| Privatisation | Transfer of government-owned enterprises to private sector (disinvestment) |
| Globalisation | Opening Indian economy to foreign trade, investment, and technology |
PSC context: “In which year were economic reforms introduced?” — 1991. “Who was the Finance Minister?” — Dr. Manmohan Singh (under PM P.V. Narasimha Rao).
Poverty and Development
Poverty Line
The poverty line is the minimum income level below which a person is considered poor.
| Measure | Detail |
|---|---|
| Tendulkar Committee (2011-12) | ₹816/month (rural), ₹1,000/month (urban) |
| Rangarajan Committee (2014) | ₹972/month (rural), ₹1,407/month (urban) |
| Current basis | Calorie intake: 2,400 cal/day (rural), 2,100 cal/day (urban) |
Human Development Index (HDI)
| Component | Measures |
|---|---|
| Health | Life expectancy at birth |
| Education | Mean years of schooling + expected years of schooling |
| Standard of living | Per capita income (GNI) |
- HDI is published by UNDP (United Nations Development Programme)
- Range: 0 to 1 (higher = more developed)
- Kerala has traditionally ranked highest among Indian states in HDI (though Goa and Delhi challenge in some recent reports)
PSC favourite: “Which Indian state has the highest HDI?” — Kerala. This is tested frequently and connects economy with Kerala GK.
Important Economic Institutions
| Institution | Established | Purpose |
|---|---|---|
| RBI | 1935 | Central bank; monetary policy |
| SEBI | 1992 (statutory) | Regulates stock markets |
| NABARD | 1982 | Rural and agriculture credit |

Taxes in India
Direct vs Indirect Taxes
