🧾 📊 Who Keeps Track of all the numbers required for counting the GDP or National Income?
👉 The responsibility lies with:
🏛️ National Statistical Office (NSO)
Under: Ministry of Statistics and Programme Implementation (MoSPI)
What they do:
-
Collect data on production, income, expenditure
-
Classify goods into final and intermediate
-
Calculate India’s GDP, GNP, NDP, etc.
-
Release reports like National Accounts Statistics
🔍 How Do They Know What’s Final or Intermediate?
The NSO doesn't track every individual transaction. Instead, they:
📦 Use Sectors & Categories:
-
Agriculture
-
Manufacturing
-
Services
Each sector reports: -
Gross output
-
Inputs used (raw material, energy, etc.)
Then they apply the formula:
🧠 Value Added Method (one of the GDP methods)
Formula:
Value Added = Value of Output – Value of Intermediate Consumption
So instead of counting every stage, they subtract intermediate goods from total output to find the "value added" at each stage.
🏗️ Example: Roti Supply Chain
| Stage | Output Value | Inputs Used | Value Added |
|---|---|---|---|
| Wheat Farmer | ₹100 | ₹0 | ₹100 |
| Flour Mill | ₹200 | ₹100 (wheat) | ₹100 |
| Roti Maker | ₹300 | ₹200 (flour) | ₹100 |
👑 GDP = Sum of Value Added = ₹100 + ₹100 + ₹100 = ₹300
We don’t count ₹100 + ₹200 + ₹300 = ₹600 (❌ double counting!)
🛠️ Tools They Use:
-
Economic Census
-
Annual Survey of Industries
-
Input-Output Tables
-
National Sample Surveys
-
Corporate financial filings (for services/companies)
🧠 So the Answer to Your Question:
Who keeps track of what is final and intermediate?
✅ India's NSO using sector-level data and value-added accounting — not individual transactions.
They ensure:
-
Final goods are properly counted
-
Intermediate goods are excluded (indirectly via subtraction)
