Gini index
Definition
The Gini index (or coefficient) is a composite indicator of inequalities in wages (in income, standard of living, etc.). It varies between 0 and 1. It would be equal to 0 in situations of perfect equality in which all wages, income and standard of living, etc. were equal. At the other end of the scale, it would be equal to 1 in the most unequal situation possible, where all wages (income, standards of living, etc.) except one were zero. Between 0 and 1, the higher the Gini index, the greater the inequality.
Note
A fall in the GINI index observed between two dates indicates an overall reduction in inequalities. Conversely, a rise in the index reflects an overall increase in inequalities.
