How do you calculate Gini index in statistics?
The Gini index is the ratio of the area below the ‘equality line’ (an area which is exactly 0.5) minus the area below the Lorenz curve to the area below the ‘equality line’. If the area below a specific Lorenz curve is given by 0.20, the Gini coefficient will be (0.5 – 0.20)/(0.5) = 0.6.
How do you interpret Gini coefficient?
The Gini index is a measure of the distribution of income across a population. A higher Gini index indicates greater inequality, with high-income individuals receiving much larger percentages of the total income of the population.
What is the ideal Gini coefficient?
The Gini coefficient ranges from 0, indicating perfect equality (where everyone receives an equal share), to 1, perfect inequality (where only one recipient or group of recipients receives all the income).
What is Gini index What is the formula for calculate same?
The Gini coefficient is equal to the area below the line of perfect equality (0.5 by definition) minus the area below the Lorenz curve, divided by the area below the line of perfect equality. In other words, it is double the area between the Lorenz curve and the line of perfect equality.
What is the difference between Gini index and Gini coefficient?
The Gini coefficient is a measure of inequality of a distribution. The Gini index is the Gini coefficient expressed as a percentage, and is equal to the Gini coefficient multiplied by 100. (The Gini coefficient is equal to half of the relative mean difference.)
What does a 0.5 Gini mean?
Gini index < 0.2 represents perfect income equality, 0.2–0.3 relative equality, 0.3–0.4 adequate equality, 0.4–0.5 big income gap, and above 0.5 represents severe income gap. The Gini Index is the indicator par excellence, used to measure the level of distribution of monetary income and derived from social inequality.
Is a Gini coefficient of 0 good?
A Gini coefficient of zero expresses perfect equality, where all values are the same (e.g. where everyone has the same income). The Gini coefficient was proposed by Gini as a measure of inequality of income or wealth.

What does a low Gini coefficient mean?
The Gini coefficient is the most well-known measure of income inequality. A Gini coefficient of zero means there is an equal distribution of income, whereas a number closer to one indicates greater inequality. The lower the Gini coefficient, the more equal the society is said to be.
What is the meaning of Gini index?
The Gini index (or coefficient) is a synthetic indicator that captures the level of inequality for a given variable and population. It varies between 0 (perfect equality) and 1 (extreme inequality). Between 0 and 1, the higher the Gini index, the greater the inequality.
Is Gini coefficient accurate?
The Gini coefficient is commonly used as a measure of inequality of income, consumption, or wealth. and remains unchanged in the rest of population, then the overall inequality declines. The Gini coefficient does not have this property.
