在讨论Inclusive growth policy 的时候，我提到我们可以用GINI系数来分析relative poverty。

维基百科上的定义是（我知道谁都可以编辑维基百科，但是，维基的审稿人水平还是很高的）。Relative poverty views poverty as socially defined and dependent on social context, hence relative poverty is a measure of income inequality. Usually, relative poverty is measured as the percentage of population with income less than some fixed proportion of median income. There are several other different income inequality metrics, for example the Gini coefficient or the Theil Index.

所以我认为可以用GINI系数去分析相对贫困。但是导师的feedback直接说Please be careful as the Gini coefficient measures inequality NOT relative poverty which is measured using the mean income. You  are again mixing inequality and relative poverty, please clarify your understanding of these two concepts.

只是the percentage of population with income less than some fixed proportion of median income的数据不好找，而且各国之间没有统一标准无法对比，所以哪位前辈可以告诉我导师说的是对是错，还是说我可以继续使用GINI来分析？

诚恳求教
