Gini Coefficient Calculator
Calculate income inequality using Gini coefficient
About this calculator
The Gini Coefficient Calculator measures income inequality within a population, providing a statistical representation of wealth distribution. This economic indicator ranges from 0 (perfect equality) to 1 (maximum inequality), helping economists, researchers, and policymakers assess economic disparities. By calculating the Gini coefficient, you can compare inequality levels between different countries, regions, or time periods, making it an essential tool for economic analysis and social policy development.
How to use
Enter income data for your population sample, either as individual incomes or income groups with frequencies. The calculator will automatically sort the data and compute the Gini coefficient using the standard formula. Results display the coefficient value along with an interpretation of the inequality level.
Frequently asked questions
What does a Gini coefficient of 0.5 mean?
A coefficient of 0.5 indicates moderate to high inequality, where income distribution is significantly uneven across the population.
Can I use this for small sample sizes?
Yes, but larger samples provide more accurate representations of true population inequality patterns and trends.
How often should Gini coefficients be calculated?
For policy analysis, annual calculations are common, though the frequency depends on your research objectives and data availability.
