GDP & National Income

Every quarter, the Government announces: "India's GDP grew by 7.2%!" News channels debate. Stock markets react. But what does it actually mean?

1. What is GDP?

Gross Domestic Product (GDP) = Total value of all goods and services produced within India's borders in one year.

Think of it as: India's Annual Income Statement.

Simple Example:

Imagine India has only 3 people:

  • Farmer grows rice worth ₹100.
  • Baker makes bread worth ₹50 (using rice from farmer).
  • Tailor stitches clothes worth ₹30.

What is GDP? Wrong: 100 + 50 + 30 = ₹180 (This counts rice twice!). Right: Only count final goods = Bread (₹50) + Clothes (₹30) = ₹80.

Or, count value added at each stage:

  • Farmer: ₹100 (Rice).
  • Baker: ₹50 - ₹100 (He bought rice) = Actually, he adds value. Let me correct this.

Actually, simpler approach: GDP = Final consumption + Investment + Govt Spending + Net Exports

2. The GDP Formula (Expenditure Approach)

GDP = C + I + G + (X - M)

  • C = Consumption (You buying groceries, phones, movies).
  • I = Investment (Companies building factories, buying machinery).
  • G = Government Spending (Roads, schools, salaries).
  • X = Exports (India selling IT services abroad).
  • M = Imports (India buying iPhones from China).

Example:

  • Indians spend ₹100 Lakh Cr.
  • Companies invest ₹30 Lakh Cr.
  • Govt spends ₹20 Lakh Cr.
  • Exports: ₹50 Lakh Cr, Imports: ₹60 Lakh Cr.
  • GDP = 100 + 30 + 20 + (50 - 60) = ₹140 Lakh Cr.

3. Nominal vs Real GDP (The Inflation Trick)

Nominal GDP (Current Prices)

Just multiply quantity by current price.

Problem: If prices double but production doesn't change, GDP looks like it doubled!

Real GDP (Constant Prices)

Adjusts for inflation. Uses a base year price.

Example:

  • 2020: 100 apples at ₹10 = ₹1,000 (Base Year).
  • 2023: 100 apples at ₹20 = ₹2,000 (Nominal GDP).
  • Real GDP (2023): Still ₹1,000 (No extra apples produced, just inflation).

Rule: Always look at Real GDP Growth to measure true economic progress.

4. GDP vs GNP

  • GDP: Production inside India (regardless of who owns the company).
    • Apple's iPhone factory in India → Counts in India's GDP.
  • GNP (Gross National Product): Production by Indian citizens (wherever they are).
    • An Indian doctor working in USA → Counts in India's GNP, not GDP.

India's Case: GDP ≈ GNP (Most production is by Indians).

5. Per Capita GDP (The Real Story)

Total GDP is misleading.

  • India's GDP: $3.7 Trillion (5th largest).
  • But Per Capita GDP: $2,500 (Average income per person).
  • USA Per Capita: $70,000.

Why? India has 1.4 billion people. Divide the pie by more people → smaller slice each.

6. Limitations of GDP

GDP is NOT a measure of happiness or well-being.

What GDP Doesn't Capture:

  1. Inequality: India's GDP is high, but 60% of wealth is with 1% of people.
  2. Unpaid Work: Housework, volunteering.
  3. Environmental Damage: Cutting forests increases GDP (Timber sales) but destroys ecology.
  4. Black Money: Unreported income (₹50 Lakh Cr+ in India!).

Better Metric: HDI (Human Development Index) = GDP + Education + Health.

7. India's GDP Growth Story

  • 1991: Liberalization. GDP growth averaged 6-7%.
  • 2000s: IT Boom. GDP crossed $1 Trillion.
  • 2020: COVID crash (-7.3% growth).
  • 2023: Recovered (7%+ growth).

Target: Become a $5 Trillion economy by 2027 (Currently $3.7T).

7-Day Action Plan

Day 1: Google "India GDP growth rate last quarter". Understand the headline.
Day 2: Compare India's GDP per capita with China, USA, and Bangladesh.
Day 3: Read the Economic Survey (Govt releases it every year before the Budget).
Day 4: Understand "GDP Deflator" = (Nominal GDP / Real GDP) x 100. It measures inflation.
Day 5: Check which sectors contribute most to India's GDP (Services 55%, Industry 25%, Agriculture 20%).
Day 6: Learn about "Base Year" revision. India changed base year from 2011-12 to 2022-23 recently.
Day 7: Read Amartya Sen's critique: "GDP measures everything except what makes life worthwhile."
