Gini Coefficient Calculator
Category: StatisticsCalculate the Gini coefficient to measure income inequality in a population. The Gini coefficient ranges from 0 (perfect equality) to 1 (perfect inequality). This tool helps economists, researchers, and policy makers understand wealth distribution patterns.

What Is the Gini Coefficient?
The Gini coefficient is a statistical measure used to evaluate income inequality within a population. It helps quantify how evenly or unevenly income is distributed. A Gini value of 0 indicates perfect equality—everyone earns the same amount—while a value of 1 represents perfect inequality—one person earns everything, and everyone else earns nothing.
G = (Σ |xi - xj|) / (2n²μ)
Where:
- xi, xj: individual income values
- n: number of income entries
- μ: mean income

FAQs
Q: What types of data can I input?
You can input raw individual income values, grouped ranges with counts, or percentile-income pairs. Make sure your data follows the format shown in the input area.
Q: What does the Lorenz curve show?
The Lorenz curve visualizes income distribution. The closer the curve is to the line of equality, the more equal the distribution.
Q: Can I use this for wealth data?
No. The Gini coefficient specifically measures income inequality. It doesn't account for wealth or asset distribution.
Q: Is there a recommended sample size?
Larger datasets provide more accurate results. A minimum of 10 income entries is required, but 100+ is ideal for statistical reliability.
