The Gini coefficient is an important indicator to measure the degree of inequality in distribution. It is generally believed in the international community that when the Gini coefficient is lower than 0.2, it means the absolute average income; 0.3-0.4 means relatively reasonable; 0.4-0.5 means a large income gap; 0.6 or more means the income gap Great disparity.
The option "The Gini coefficient can take any value between zero and 1. The more equal the income distribution, the smaller the Gini coefficient" is incorrect based on the conclusions from the above.
