TED-Ed（视频版）

France has kept its Gini index below 0.32 since 1979.

TED-Ed（视频版）

A Gini index of 0 indicates perfect equality— everyone has exactly the same income or wealth.

基尼系数为 0 表示完全平等——每个人都有完全相同的收入或财富。

TED-Ed（视频版）

One way to estimate inequality is with a number called the Gini index, which is calculated by comparing the income or wealth distribution of a perfectly equal society to the actual income or wealth distribution.

估计不平等的一种方法是使用称为基尼指数的数字，该指数是通过将完全平等社会的收入或财富分配与实际收入或财富分配进行比较来计算的。

2014年世界银行基尼系数世界地图。[1]基尼系数越小收入分配越平均，基尼系数越大收入分配越不平均。
图中横轴为人口累计百分比，纵轴为该部分人的收入占人口总收入的百分比，三条色线各表示不同情况下后者和前者的比例。绿线表示人口收入分配处于绝对平均状态，蓝线表示绝对不平均（即所有收入由一人独占），红线则表示实际情况。红线和绿线之间的面积越小，则收入分配越平等。

坚尼系数（英语：Gini coefficient），是20世纪初意大利学者科拉多·基尼根据劳伦茨曲线所定义的判断年收入分配公平程度的指标。是比例数值，在0和1之间。坚尼指数（Gini index）是指坚尼系数乘100倍作百分比表示。在民众收入中，如坚尼系数最大为“1”，最小等于“0”。前者表示居民之间的年收入分配绝对不平均（即该年所有收入都集中在一个人手里，其余的国民没有收入），而后者则表示居民之间的该年收入分配绝对平均，即人与人之间收入绝对平等，这坚尼系数的实际数值只能介于这两种极端情况，即0～1之间。坚尼系数越小，年收入分配越平均，坚尼系数越大，年收入分配越不平均。要注意基尼系数只计算某一时段，如一年的收入，不计算已有财产，因此它不能反映国民的总积累财富分配情况。

Gini coefficient 基尼系数

Graphical representation of the Gini coefficientThe graph shows that the Gini coefficient is equal to the area marked A divided by the sum of the areas marked A and B, that is, Gini = A / (A + B). It is also equal to 2A and to 1 - 2B due to the fact that A + B = 0.5 (since the axes scale from 0 to 1).
Richest u % of population (red) equally share f % of all income or wealth, others (green) equally share remainder: G = f − u. A smooth distribution (blue) with same u and f always has G > f − u.
The change in Gini indices has differed across countries. Some countries have change little over time, such as Belgium, Canada, Germany, Japan, and Sweden. Brazil has oscillated around a steady value. France, Italy, Mexico, and Norway have shown marked declines. China and the US have increased steadily. Australia grew to moderate levels before dropping. India sank before rising again. The UK and Poland stayed at very low levels before rising. Bulgaria had an increase of fits-and-starts. .svg alt text
Growth spells last longer in more equal countries. A 10 percentile increase in equality (represented by a change in the Gini coefficient from 40 to 37) increases the expected length of a growth spell by 50 percent. Percentage changes in GDP growth spell length are shown as each factor moves from 50th to 60th percentile and all other factors are held constant. Income distribution is measured by the Gini coefficient.[29]

The Gini coefficient (also known as the Gini index or Gini ratio) (/dʒini/ jee-nee) is a measure of statistical dispersion intended to represent the income distribution of a nation's residents, and is the most commonly used measure of inequality. It was developed by the Italian statistician and sociologist Corrado Gini and published in his 1912 paper Variability and Mutability (Italian:Variabilità e mutabilità).
