Methodology:
To determine the richest country in the world, 24/7 Wall St. reviewed data on gross national income per capita for 193 countries and special regions with available data from the World Bank. The World Bank estimates GNI per capita using the purchasing power parity method, and figures are in current international dollars. All data on GNI per capita is based on the most recent available year for a given country.
Additional data, measuring GDP in current international dollars, population, life expectancy at birth, and access to electricity also came from the World Bank. All data are for the most recent year available for every country.
We also considered data on levels of public sector corruption in 2020 from the nonprofit, international watchdog and anti-corruption group, Transparency International.
