Gini coefficient


Definition:
The measure of income distribution inequality; it ranges between 0 and 1 (or if multiplied by 100 – between 0 and 100). This indicator would be 0 (homogenous distribution) if all the persons had the same income, whereas it would be 1 if all the persons except one had 0 income. Thus the higher the indicator, the higher the income concentration and therefore, the greater the income inequalities.
