Which metric expresses living standards by dividing a country's GDP by its population?

• A. Real GDP
• B. GDP per Capita
• C. GDP Growth Rate
• D. Net Domestic Income

Answer: (B)

GDP per capita shows living standards by distributing the country's economic output across its people. It’s calculated by dividing total GDP by the population, giving an average economic output per person. This per-person perspective lets us compare how prosperous people are across countries with different population sizes and over time, even when total GDP differs. Of course, it has caveats—it doesn’t capture income distribution, non-market activities, or cost of living, but it’s the standard way to gauge the typical level of economic well-being.

Real GDP, by contrast, is about the total value of goods and services adjusted for inflation, not per person. GDP growth rate measures how fast the economy is growing over time, not the average standard of living at a point in time. Net Domestic Income isn’t a standard per-person living-standards metric.
