Standard Measure of Economic Growth

Steps:

• Recall that economic growth tracks the increase in an economy's production of goods and services over time.
• Identify the primary indicator used globally for this purpose.
• Evaluate each option against the definition of comprehensive economic output.
• Select the option that captures total national production.

Why B is correct:

• Gross Domestic Product (GDP) is defined as the total monetary value of all final goods and services produced within a country's borders in a year, directly measuring economic growth via its annual percentage change.

Why the others are wrong:

• A: Consumer spending reflects only household expenditures, a partial component of GDP, not overall growth.
• C: Manufacturing and construction output measures specific sectors, ignoring services and agriculture.
• D: The Retail Price Index (RPI) tracks price changes for consumer goods, indicating inflation rather than production growth.

Final answer: B
