Final answer:
Two other ways to compare the standard of living in countries around the world are by considering factors like life expectancy, education levels, income inequality, and access to healthcare, as well as using the Human Development Index (HDI).
Step-by-step explanation:
One way to compare the standard of living in countries around the world is by looking at their Gross Domestic Product (GDP) per capita. This is calculated by dividing a country's GDP by its population. Another way is to consider factors such as life expectancy, education levels, income inequality, and access to healthcare. Additionally, the Human Development Index (HDI) is a measure that combines multiple indicators of well-being to compare countries' overall quality of life.
