📘 National Income Accounting – Complete UPSC Notes


🔹 1. Basic Concepts

  • Domestic Territory: Political frontiers + embassies, ships, aircrafts owned by residents abroad.

  • Normal Resident: Lives in country ≥1 year; includes citizens abroad (for work ≥1 yr), excludes foreign diplomats.

  • Factor Income: Wages, rent, interest, profits (earned by rendering factor services).

  • Transfer Income: Unilateral, no productive activity (e.g., pensions, donations, subsidies).


🔹 2. Gross Value Added (GVA)

  • At firm level:
    GVAi=Value of Output−Intermediate ConsumptionGVA_i = Value\ of\ Output - Intermediate\ ConsumptionGVAi=Value of Output−Intermediate Consumption
    OR
    GVAi=Sales+ΔInventories−Intermediate ConsumptionGVA_i = Sales + \Delta Inventories - Intermediate\ ConsumptionGVAi=Sales+ΔInventories−Intermediate Consumption

  • At economy level:

    • GVA at Factor Cost = Sum of factor incomes

    • GVA at Basic Prices = GVA at FC + Net Production Taxes

    • GVA at Market Prices = GVA at Basic Prices + Net Product Taxes

CSO (NSO) reports GVA at Basic Prices (base year 2011-12).


🔹 3. GDP (Gross Domestic Product)

  • Definition: Market value of all final goods & services produced within domestic territory in a year (by residents + non-residents).

  • Formulas:

    • Expenditure method:
      GDP=C+I+G+(X−M)GDP = C + I + G + (X - M)GDP=C+I+G+(X−M)

    • Income method:
      GDP=Compensation to Employees+Rent+Interest+Profit+MixedIncome+Net Indirect TaxesGDP = Compensation\ to\ Employees + Rent + Interest + Profit + Mixed Income + Net\ Indirect\ TaxesGDP=Compensation to Employees+Rent+Interest+Profit+MixedIncome+Net Indirect Taxes

  • Variants:

    • GDP at FC = GDP at MP – Net Indirect Taxes

    • NDP = GDP – Depreciation


🔹 4. GNP (Gross National Product)

  • Definition: Market value of all final goods & services produced by residents (within or outside domestic territory).

  • Formula:
    GNP=GDP+NFIAGNP = GDP + NFIAGNP=GDP+NFIA
    Where, NFIA = Factor Income earned from abroad – Factor Income paid to non-residents.

  • NDP (Net Domestic Product) = GDP – Depreciation

  • NNP (Net National Product) = GNP – Depreciation


🔹 5. National Income (NI)

  • Definition: NNP at Factor Cost.

  • Formula:
    NI=NNP at MP−Net Indirect TaxesNI = NNP\ at\ MP - Net\ Indirect\ TaxesNI=NNP at MP−Net Indirect Taxes

  • Includes: Wages, rent, interest, profit, mixed income of self-employed.

  • Excludes: Transfer payments, capital gains, illegal income.


🔹 6. Disposable Incomes

  • Personal Income (PI) = NI – Undistributed Profits – Corporate Tax – Interest on govt. loans + Transfer Payments

  • Personal Disposable Income (PDI) = PI – Personal Taxes – Non-tax Payments

  • National Disposable Income (NDI) = NNP at MP + Net Current Transfers from Abroad


🔹 7. Private Income

  • Definition: Factor income from private sector + interest on national debt + NFIA + Transfers from govt. + Transfers from rest of world


🔹 8. Per Capita Income

  • Formula:
    PCI=NNP at FCPopulationPCI = \frac{NNP\ at\ FC}{Population}PCI=PopulationNNP at FC

  • Importance: Indicates average standard of living.


🔹 9. Price Indices & Deflators

  • GDP Deflator = Nominal GDPReal GDP×100\frac{Nominal\ GDP}{Real\ GDP} \times 100Real GDPNominal GDP×100

    • Broad measure of inflation, includes all goods & services.

  • CPI (Consumer Price Index): Measures retail inflation.

  • WPI (Wholesale Price Index): Bulk transaction prices, not directly consumer oriented.


🔹 10. Methods of NI Estimation

  • Income Method: Sum of factor incomes.

  • Expenditure Method: Sum of final expenditures.

  • Output/Production Method: Sum of value added across sectors.


🔹 11. India’s Practice

  • Agency: National Statistical Office (NSO), MoSPI.

  • Base Year: 2011–12.

  • Reported Measures: GDP at Market Prices, GVA at Basic Prices.

  • Releases: Quarterly + Annual estimates.
