Inequality: The Gini Coefficient
The Gini coefficient ranges from zero, when everyone has the same income, to 1, when a single individual receives all the income. A Gini coefficient above 0.4 is often seen as an important point. Inequality above this level is frequently associated with political instability and growing social tensions.

Gini coefficients for a selection of countries
(Data is taken from the World Bank databank, most recent published data is used, mainly for 2008-09)
|Country Name||Gini Coefficient Value||Country Name||Gini Coefficient Value|
|Russian Federation||42.3||United Kingdom||36.1|
Inequality is substantially higher in developing than in advanced economies.
- 1.Thinking about countries with much higher values for the Gini coefficient, can you think of reasons why income inequality is much higher?
- 2.Considering countries with lower levels of income inequality – can you spot anything about those countries selected that might explain why their Gini coefficient is lower than for the UK?
- 3.If you were constructing a Gini coefficient for wealth rather than income, would you expect inequality to be higher or lower for the United Kingdom?
