What is the Gini index and what it measures?
The Gini Index is a summary measure of income inequality. The Gini coefficient incorporates the detailed shares data into a single statistic, which summarizes the dispersion of income across the entire income distribution.
What does Gini coefficient include?
The Gini coefficient is the area between the Lorenz curve of the income distribution and the diagonal line of complete equality, expressed as a proportion of the triangular area between the curves of complete equality and inequality.
What does a 0 Gini coefficient mean?
Another way of thinking about the Gini coefficient is as a measure of deviation from perfect equality. The further a Lorenz curve deviates from the perfectly equal straight line (which represents a Gini coefficient of 0), the higher the Gini coefficient and the less equal the society.

What does Gini index measure?
“The Gini index measures the extent to which the distribution of income (or, in some cases, consumption expenditure) among individuals or households within an economy deviates from a perfectly equal distribution.”. The Gini Index ranges from 0% to 100% or 0 to 1.
What is a good Gini?
According to econometrics, the ideal Gini coefficient lies between 0,25 and 0,40. This is because at a level where brain surgeons, rocket scientists and waiters all receive the same wage, there is no financial incentive to study physics or neuroscience.
How does the Gini index work?
The Gini index is often represented graphically through the Lorenz curve , which shows income (or wealth) distribution by plotting the population percentile by income on the horizontal axis and cumulative income on the vertical axis.
