How It Works

Calculate the Gini coefficient from income distribution data using the Lorenz curve area method. Values range 0 (perfect equality) to 1 (maximum inequality). Used by the World Bank and UN to compare inequality across nations

Each component has a specific meaning:

  • Income distribution data — The income distribution data recorded for the scenario being assessed.

Note: Interpret the gini coefficient result against the thresholds and context described above.

How to Use
