1-1 Decoding the GDP Numbers

Gross Domestic Product measures a country’s economic health. It includes all goods and services produced within a country over a specific period, usually a year or a quarter.

Think of Gross domestic product as the total income of a country. Just like you count how much money you earn in a year from your job. A country counts how much it “earns” from producing goods and services.

How to Measure Gross Domestic Product?

There are three primary Approaches including

1. Production Approach
2. Income Approach
3. Expenditure Approach

Production Approach

This method is used to calculate a country’s Gross Domestic Product. It does so by adding up the total value of goods and services produced within a country. It focuses on measuring economic output at different stages of production.

The Formula for the Production Approach is

Gross Domestic Product = Σ Value of Output – Value of Intermediate Consumption

Where

• C: Consumption expenditure by households.
