Real GDP per capita is a more accurate measure of a country's economic performance than nominal GDP because it accounts for inflation and provides insight into the average income of citizens, but it does not consider income distribution within the population.

Real GDP per capita is a way to measure how well a country's economy is doing by looking at the value of all goods and services produced, adjusted for inflation, and divided by the number of people in the country. This means it gives a clearer picture of the average income that each person might expect, which helps us understand the standard of living. For example, if a country has a nominal GDP of $1 trillion and a population of 100 million, its nominal GDP per capita would be $10,000. However, if inflation is high and we adjust that GDP to account for it, the real GDP per capita might show that people actually earn less in terms of purchasing power. While this measure is useful, it doesn't tell us if the wealth is shared equally among the people, which is important for understanding overall well-being.
