### Economic inequality

income inequalityinequalitywealth gap
Income inequality metrics or income distribution metrics are used by social scientists to measure the distribution of income and economic inequality among the participants in a particular economy, such as that of a specific country or of the world in general.
A widely used index is the Gini coefficient, but there are also many other methods.

### Poverty

The concept of inequality is distinct from poverty and fairness.
There are several other different income inequality metrics, for example, the Gini coefficient or the Theil Index.

### Gini coefficient

Gini indexGiniequality
Among the most common metrics used to measure inequality are the Gini index (also known as Gini coefficient), the Theil index, and the Hoover index.
The Gini coefficient was proposed by Gini as a measure of inequality of income or wealth.

### Distribution (economics)

Classical economists such as Adam Smith, Thomas Malthus and David Ricardo were mainly concerned with factor income distribution, that is, the distribution of income between the main factors of production, land, labour and capital.

### Theil index

Among the most common metrics used to measure inequality are the Gini index (also known as Gini coefficient), the Theil index, and the Hoover index.
Dividing T T by \ln N can normalize the equation to range from 0 to 1, but then the independence axiom is violated: and does not qualify as a measure of inequality.

### Hoover index

Among the most common metrics used to measure inequality are the Gini index (also known as Gini coefficient), the Theil index, and the Hoover index.

### Pareto principle

This is slightly more unequal than the inequality in a system to which the "80:20 Pareto principle" applies.
Using the "A : B" notation (for example, 0.8:0.2) and with A + B = 1, inequality measures like the Gini index (G) and the Hoover index (H) can be computed.

### Lorenz curve

The reason for its popularity is that it is easy to understand how to compute the Gini index as a ratio of two areas in Lorenz curve diagrams.

### Atkinson index

The Theil index can be transformed into an Atkinson index, which has a range between 0 and 1 (0% and 100%), where 0 indicates perfect equality and 1 (100%) indicates maximum inequality.
