Countries With Highest Income Inequality

The Gini Index measures income inequality on a scale of 0 (perfect equality) to 100 (perfect inequality). South Africa consistently has the highest Gini score in the world, a legacy of apartheid that concentrated wealth and land ownership among a small minority. Latin American and sub-Saharan African countries dominate the most unequal end of the spectrum, reflecting colonial legacies, land concentration, weak institutions, and limited social safety nets. High inequality is associated with lower economic growth, worse health outcomes, higher crime rates, and political instability. The most equal countries — in Scandinavia and Central Europe — achieve lower inequality through progressive taxation, universal healthcare, free education, and strong labor protections. The relationship between economic growth and inequality is hotly debated: some argue inequality is a necessary byproduct of dynamism, while others see it as a barrier to shared prosperity.

Methodology

Rankings are based on American Community Survey (ACS) 2023 5-Year estimates from the US Census Bureau. All 50 states and the District of Columbia are included. The ACS surveys approximately 3.5 million households annually and provides detailed demographic, social, economic, and housing data. 5-Year estimates offer the most reliable data for state-level comparisons by averaging responses over a 60-month period. Percentages may not sum to 100% due to rounding.
