The technological advancement in these countries has brought about wealth and prosperity to their citizens, thereby making it crucial to grade the positions of different countries based on their economic prosperity and even maybe overall happiness of their inhabitants.

The top 10 wealthiest countries in the world will include a list of countries selected based on their current Gross domestic product (GDP) per capita and the Purchasing Power Parity per capita.

The GDP is a monetary representation that shows the market value of the goods and services produced in a country over a specific period, usually one year. GDP per capita represents a country's GDP divided by the population at the time.

The GDP is not a perfect metric in comparing the living standards across different countries or how rich a country is because it does not reflect the cost of living and inflation rates in countries.

The GDP is measured by taking notes of total exports, imports, investments, government spending, etc. However, labour, which contributes to differences in standard of living and the final cost of goods, is not moveable and may not accurately represent the GDP.

For instance, a Big Mac (beverage) might cost 10 USD in the United States but sell at 2000 NGN in Nigeria. Approximate calculations using the FOREX rate (I USD = N560) at the time of this writing shows that with the same 10 USD, a Nigerian can get at least 4 Big Macs in Nigeria; the reason could be as a result of the difference in the cost of labour between Nigeria and the United States.

To better analyse the top 10 richest countries in the world in 2022, the GDP per capita is adjusted based on the Purchasing Power Parity (PPP) per capita, which considers the difference in the standard of living between countries.

PPP is a more accurate measurement of wealth distribution across different countries because it compares currencies by using the various costs of a basket of goods or food in each country.

With the PPP, Economists can measure how rich a country is and get an overview of the standard of living in different countries across the globe.

Below is the list of the world top 10 richest countries in 2022.

The chances of being on the list of the top 10 richest countries in the world are directly related to the GDP (adjusted PPP) per capita and the population.

The above proves that both the government and private corporations have a crucial role in ensuring that wealth is distributed equally.
