What does Gross Domestic Product measure?

• A. Gross Domestic Product (GDP)
• B. Gross National Income (GNI)
• C. Net Domestic Product (NDP)
• D. Personal Income

Answer: (A)

Gross Domestic Product measures the total market value of all final goods and services produced inside a country's borders in a given period. It focuses on where production occurs, not who owns the resources, and counts only final goods to avoid double counting. This makes GDP a broad gauge of a country’s overall economic activity and the size of its economy during that time.

GDP can be estimated in several ways, such as by summing expenditures (consumption, investment, government spending, and net exports) or by summing incomes earned in the production process, with real GDP adjusting for price changes to compare across years.

Other measures differ: Gross National Income tracks the income residents earn from all sources, including abroad; Net Domestic Product subtracts depreciation from GDP; Personal Income sums what individuals receive, not the total value of domestic production.
