What is the term for a country's economic output divided by its population?

The term for a country’s economic output divided by its population is GDP per capita.

GDP per capita is calculated by dividing a country’s gross domestic product by its population. It converts a large economy-wide total into an average amount of output associated with each person, making it useful for broad comparisons between countries or across time. It is an average, however, not a measure of what each individual earns or owns.

Comparisons require care. Nominal GDP per capita uses current prices and exchange rates, while real GDP per capita adjusts for inflation when tracking changes over time. Purchasing-power-parity figures adjust for differences in local price levels and are often more informative for comparing material living standards.

GDP per capita is not the same as GNP per capita: GDP measures production within a country’s borders, whereas GNP focuses on income associated with a country’s residents or nationals, including relevant cross-border flows. It also differs from the GDP deflator, which measures economy-wide price changes, and from GDP growth rate, which measures how quickly output changes.
