Many countries use GDP per capita to compare the quality of life in different countries.

Explanation:

GDP per capita is gross domestic product divided by the number of inhabitants of a country. GDP is the sum of all goods in a country, and the higher the GDP, the more it demonstrates how developed that country is, and can be classified among poor, rich or developing countries.

Per capita GDP is used as an indicator of a country's quality of life, because the richer the country is, the more its citizens benefit. For this reason, we can conclude that many countries use per capita GDP to compare the quality of life of different countries.
