Describe different methods of measuring National Income and explain by which method National Income is measured in India.

Methods of Measuring National Income and Methodology Used in India

National Income measures the total net monetary value of all final goods and services produced by the normal residents of a country during a financial year (represented as NNP at Factor Cost / NNP at Market Prices).

1. Three Classical Methods of Measuring National Income:

• 1. Product / Value-Added Method (उत्पादन विधि):
  • Calculates the Gross Value Added (GVA) at each stage of production across Agriculture, Industry, and Services: GVA = Value of Output - Intermediate Consumption.
• 2. Income Method (आय विधि):
  • Measures the total factor payments received by factors of production: National Income = Wages (Labor) + Rent (Land) + Interest (Capital) + Profit (Entrepreneurship) + Mixed Income of Self-Employed.
• 3. Expenditure Method (व्यय विधि):
  • Measures total aggregate spending on final goods and services: GDP = C (Private Consumption) + I (Investment / GFCF) + G (Government Expenditure) + (X - M) (Net Exports).

2. National Income Measurement Methodology in India:

• Nodal Agency: Estimated by the National Statistical Office (NSO), Ministry of Statistics and Programme Implementation (MoSPI).
• Combination / Mixed Method Approach:
  • Product (Value-Added) Method: Applied to commodity-producing sectors — Agriculture, Forestry, Fishing, Mining, and Manufacturing.
  • Income Method: Applied to tertiary service sectors — Banking, Insurance, Real estate, Trade, Transport, and Public Administration.
  • Expenditure Method: Used cross-sectionally to compute macroeconomic aggregates (Gross Capital Formation, Final Consumption).
• Headline Metric & Base Year: Since the 2015 methodology revision, GDP at Market Prices (Base Year: 2011–12) and GVA at Basic Prices serve as headline indicators.
