Final answer:
GDP per capita is a commonly used measure by European governments to capture changes in living standards. Other ways of comparing the standard of living include the Human Development Index and the Gini coefficient.
Step-by-step explanation:
GDP per capita is a measure commonly used by many European governments to capture changes in living standards. It is a measure of the total economic output of a country divided by the population.
For example, let's say Country A has a GDP of $1 trillion and a population of 10 million. The GDP per capita would be $100,000 ($1 trillion divided by 10 million).
Other ways of comparing the standard of living in countries around the world include the Human Development Index (HDI), which takes into account factors like life expectancy, education, and income; the Gini coefficient, which measures income inequality within a country; and the poverty rate, which indicates the percentage of the population living below a certain income threshold.
