**The Gini coefficien**t is the most common indicator describing income differences. The higher value the Gini coefficient gets, the more unequally is income distributed. The biggest possible value for the Gini coefficient is one. Then the highest earning income recipient receives all the income. The smallest Gini coefficient value is 0, when the income of all income recipients is equal. In the income distribution statistics, Gini coefficients are presented as percentages (multiplied by one hundred). The Gini coefficient describes relative income differences. The Gini coefficient does not change if the incomes of all income earners change by the same percentage. The Gini coefficient is calculated based on the household-dwelling units’ disposable money income per consumption unit.
