The maximum value of Gini coefficient is "1" and the minimum value is "0". The closer the Gini coefficient is to 0, the more equal the income distribution is. International practice regards income below 0.2 as absolute average, and 0.2-0.3 as relative average; 0.3-0.4 is considered as a relatively reasonable income; 0.4-0.5 is considered as a large income gap, and when the Danquigny coefficient reaches above 0.5, it means income disparity.

Gini coefficient can objectively reflect and monitor the gap between the rich and the poor, and predict, warn and prevent the polarization between the rich and the poor. Therefore, it has been widely recognized and adopted by all countries in the world.

Some issues, such as whether taxes should be excluded, whether beneficiaries of public assistance should be excluded, whether non-local residents should be excluded, or whether they should join the government's welfare, are inconsistent, so there is no comparative standard.
