Explanation:

In economics, the Gini coefficient (sometimes expressed as a Gini ratio or a normalized Gini index) is a measure of statistical dispersion intended to represent the income or wealth distribution of a nation's residents,  and is the most commonly used measure of inequality. Gini Coefficient is a popular statistical measure to gauge the rich-poor income or wealth divide. It measures inequality of a distribution — be it of income or wealth — within nations or States. Its value varies anywhere from zero to 1; zero indicating perfect equality and one indicating the perfect inequality. Gini Coefficients can be used to compare income distribution of a country over time as well. An increasing trend indicates that income inequality is rising independent of absolute incomes.
