(2) Per capita income Explanation: Some economists believe that economic growth is meaningless if it is not distributed across different segments of population. So per capita income is considered by some as a better indicator of economic growth since it measures the average income earned per person in country in a specified year. It serves as an indicator of a country's living standards and how wealth or income is distributed across the population. However, to a vast majority Gross Domestic Product (GDP) is the most comprehensive measure of over-all economic performance.
