What financial concept measures the value of a country's economic output per person?

The concept that measures the value of a country's economic output per person is known as the standard of living. This metric encompasses not just the total economic output but translates it into an average figure that reflects how much economic production is available to each individual in the country. The standard of living takes into account various factors, including income levels, employment opportunities, and overall economic conditions, providing a more comprehensive understanding of how well individuals in that economy are doing.

In contrast, gross domestic product (GDP) focuses on the total value of all goods and services produced within a country over a specified period, without explicitly dividing it by population to assess individual economic well-being. Income distribution pertains to how income is shared among the population, addressing inequality rather than providing a direct per-person measure of output. Lastly, purchasing power parity (PPP) compares different countries' currencies through a "basket of goods" lens, measuring economic productivity and standards, but it is not specifically about output per person in the same straightforward manner as the standard of living.
