Gross Domestic Product (GDP)

Definition

Gross Domestic Product (GDP) refers to the total market value of all final goods and services produced within a country’s borders in a specified time period. GDP is a crucial indicator used to gauge the health of a country’s economy.

GDP can be measured using three approaches:

Production (or Output) Approach: Calculates GDP by adding up total production.
Income Approach: Measures GDP by summing total national income, including wages, profits, and taxes minus subsidies.
Expenditure Approach: Determines GDP by adding up all expenditures or spending in an economy, including consumption, investment, government spending, and net exports (exports minus imports).

In 1991, the United States replaced Gross National Product (GNP) with GDP as its primary measure of economic production.

Examples

United States GDP: In 2021, the GDP of the United States was approximately $23 trillion, representing robust economic activity and growth in various sectors, including technology, healthcare, and retail.
China’s GDP: China’s GDP in the same period was around $17 trillion, highlighting its significant contribution to global manufacturing and export.
India’s GDP: India’s GDP in 2021 stood at about $3 trillion, reflecting its emerging market status and growth in information technology and service industries.
