Methodology

To find the 30 countries with the worst wealth inequality, 24/7 Wall St. used income, wealth, and inequality data from WID.world’s (World Inequality Database) 2022 World Inequality Report. Because in some countries, the bottom 50% have zero or even negative net wealth, we ranked countries by the wealth gap as measured by the ratio of the top 10% share of wealth to the bottom 90% share of wealth. We provided the top 10% to bottom 50% when applicable. All 174 countries in the report are included. Data is as of 2021.

The report measures wealth inequality using the distribution of net household wealth among adults, whereas net household wealth is the sum of financial assets and non-financial assets owned by individuals, net of their debts. The report uses purchasing power parity estimates  correct for inflation using the national income deflator (base 2021). The population is of individuals over age 20.

Data on how much wealth the top 10%, mid 40%, and bottom 50% capture also came from the report. Data on gross national income per capita in current international dollars using purchasing power parity method came from the World Bank.
