Gini index

The United Nations measure the Gini index as the ratio of the average income of the top 10% (richest) compared to the bottom 20% (poorest) in the country. A higher index shows a bigger inequality of income. Here are the findings:

High income countries
Japan            24.9
Germany       28.3
Canada         32.6
France          32.7
Australia       35.2
UK               36.0
Israel             39.2
USA             40.8
Singapore      42.5
Hong Kong   43.4

Low income countries
Indonesia       34.3
Russia            39.9
China             46.9

We have seen unrest in China and Israel about the high cost of living. Both countries have high Gini index. I have included Australia and Canada as these countries are rated to provide a good standard of life for their people.

America is considered to have high income inequality. Singapore is worse than America.
