Gini coefficient

The Gini coefficient measures inequality in income distribution and its value may vary between 0 and 1. To facilitate its interpretation, frequently its values are multiplied by 100, varying between 0 and 100. The closer it is to zero the more equal the distribution that exists whereas a coefficient close to 100 implies a distribution approaching maximum inequality.

The three aggregates allow the level of equity of income distribution before and after social transfers to be seen and, therefore, the redistributing effect that social transfers have in the different countries. Considering pensions separately allows the reducing effect of the distribution inequalities of social transfers other than pensions to be observed. GC equivalised disposable income means considering all social monetary transfers; CG counting only pensions means that it does not include other social monetary transfers; CG without transfers means that does not include pensions or other social monetary transfers.
