Calculate Gini with Negative Values
Calculate Gini with Negative Values: A Comprehensive Guide
Introduction & Importance
The Gini coefficient is a widely used measure of income inequality. However, traditional Gini calculations can’t handle negative values, which can occur when comparing incomes to a poverty line. This calculator addresses that limitation, providing a more accurate assessment of income inequality.

Formula & Methodology
The formula for calculating the Gini coefficient with negative values is:
G = 1 – ∑ [(Xi – Xj) * (Yi + Yj)] / (2 * ∑ Xi * ∑ Yj)
Where:
- Xi and Yj are the incomes and poverty lines of the individuals.
- ∑ Xi and ∑ Yj are the total incomes and poverty lines.
