The GDP per capita is the most practical way to
A. Measure how much income households receive.
B. Measure how much output can be consumed on a sustainable basis.
C. Make international comparisons of the standard of living.
D. Analyze the growth rate of the economy through time.
The correct answer and explanation is :
Correct Answer: C. Make international comparisons of the standard of living.
Explanation (300 words):
Gross Domestic Product (GDP) per capita is calculated by dividing a country’s total GDP by its population. It reflects the average income or output per person and is widely used as an indicator of a country’s economic performance and the general well-being of its population.
Why Option C is Correct:
GDP per capita is especially useful for international comparisons of the standard of living. By adjusting for population size, it allows economists to compare the economic well-being of individuals across different countries, regardless of the total size of the country or economy. For example, while China has a much larger GDP than Norway, Norway has a significantly higher GDP per capita, indicating a higher average standard of living.
When GDP per capita is adjusted for purchasing power parity (PPP), it accounts for differences in cost of living and inflation rates, making comparisons even more meaningful across different economies. This adjusted figure gives a clearer picture of what people can actually afford in their countries and helps rank nations in terms of economic prosperity and access to goods and services.
Why the Other Options Are Incorrect:
- A. Measure how much income households receive: This is inaccurate because GDP includes corporate profits, government spending, and other components that are not directly received by households. Measures like disposable income or gross national income (GNI) are more appropriate for analyzing household income.
- B. Measure how much output can be consumed on a sustainable basis: This relates more closely to net national product or sustainable development indicators, not GDP per capita.
- D. Analyze the growth rate of the economy through time: While GDP itself can be used to track economic growth, GDP per capita focuses on the per-person measure and is less about overall growth trends.
GDP per capita remains a key tool in comparing economic conditions across nations.
