Why is GDP per capita used as an estimate of the average standard of living in a
country?

The GDP is the total output of goods and services produced in a year by everyone within the country's borders. Real GDP per capita removes the effects of inflation or price increases. Real GDP is a better measure of the standard of living than nominal GDP. A country that produces a lot will be able to pay higher wages.
