studying GDP and the methods of measuring macroeconomic activity, national income

helps students understand the income side of the economy. It connects production with

earnings and provides insight into how economic activity supports livelihoods and

standards of living.

Definition and Scope of National Income

National income refers to the total income earned by all factors of production within an
economy during a specific period, usually one year. It includes wages and salaries

earned by workers, rent earned by landowners, interest earned by capital owners, and

profits earned by entrepreneurs. National income focuses on earnings rather than
output, offering a complementary perspective to GDP.

GDP and National Income: Conceptual Relationship

GDP measures the market value of final goods and services produced within a country.

National income measures the income generated by that production. Because

production creates income, GDP and national income are closely linked. Economists

typically start with GDP and make adjustments to arrive at national income, highlighting

that production and income are two sides of the same process.

Factors of Production

Production requires inputs known as factors of production: labor, land, capital, and
entrepreneurship. Each factor contributes to production and receives a specific reward.

Understanding factors of production helps explain how national income is distributed

across the economy.

Wages and Salaries (Income of Labor)

Wages and salaries are payments made to workers in return for their physical and
mental efforts. They include basic pay, salaries, bonuses, and allowances. In most

economies, wages and salaries represent the largest share of national income because

labor is widely used across sectors.
