Across 131 countries worldwide, the richest 3% of residents hold 20% of the total collective household income — as do the poorest 54%. In other words, the 3% reporting the highest household incomes share the same „slice“ of collective income across countries that more than half of residents worldwide — those on the lower end of the income scale — must share. Income inequality levels are highest in sub-Saharan Africa and East Asia (predominantly China).
