Analysis:
- The Gini index, a measure of income inequality, fell 0.7 percent in 2018.
- This indicates that the level of wealth inequality has declined.
Economist Corner:
The Gini index is a statistical measure of income inequality where 0 indicates all households having the same share of income and 1 indicates one household has all the income. Thus, a reduction in the Gini index indicates that the distribution of income between households has become more equal from 2017 to 2018.
