How to Calculate GDP per Capita
GDP per capita = real GDP ÷ population (real GDP ÷ number of people), a common proxy for average output and living standards per person.
Formula
Steps
- 1Find real GDP. Use real GDP (output valued at base-year prices) rather than nominal GDP, so the measure is not distorted by inflation.
- 2Find the population. Use the total population of the country for the same year as the GDP figure.
- 3Divide real GDP by population. GDP per capita = Real GDP ÷ Population. Keep both in consistent units before dividing.
- 4Interpret the result. The answer is average real output per person, a common proxy for average living standards over time or between countries.
Worked example
If a country has real GDP of $21 trillion and a population of 331 million, then GDP per capita = 21,000,000,000,000 ÷ 331,000,000 = $63,444 per person.
Frequently asked questions
What does GDP per capita tell you?
GDP per capita tells you the average real output (and roughly the average income) produced per person, so it is used to compare living standards across countries or over time. Rising real GDP per capita generally signals improving material living standards.
Why use real GDP instead of nominal GDP for GDP per capita?
Real GDP holds prices constant, so changes reflect actual changes in output rather than inflation. Using real GDP means a rise in GDP per capita reflects more goods and services per person, not just higher prices.
What are the limitations of GDP per capita as a measure of living standards?
It is an average, so it hides how income is distributed and can rise even when most people are worse off. It also omits non-market activity (household and volunteer work), leisure, environmental quality, and the underground economy, so it understates or misstates true well-being.
How is GDP per capita different from GDP?
GDP is a country's total output, while GDP per capita divides that output by population. A country can have a large total GDP but low GDP per capita if its population is very large, which is why per-capita figures are better for comparing living standards.
