Measuring the wealth of a country can be done in a number of ways. One option is to consider a country's Gross Domestic Product (GDP), which indicates the value of all goods and services produced over a specified period of time. Another way is to analyze GDP alongside the purchasing power parity (PPP) of a given country. The PPP is an indicator of wealth that takes into account factors such as the cost of goods and services, as well as inflation.

A third method, which is the basis of this ranking, is the GDP per capita method, which measures the average income of every individual in the country. The GDP per capita is obtained by dividing a country's total GDP by its population. Unlike the PPP method, the GDP per capita approach does not take into account cost of living and inflation.
