In the discrete case, an economic inequality index may be represented by a function I(x), where x is a set of n economic values (e.g. wealth or income) x={x 1,x 2,...,x n} with x i being the economic value associated with "economic agent" i.
The Atkinson index is defined as: (, …,) = {(=) / (=) / = (,...,) = +where is individual income (i = 1, 2, ..., N) and is the mean income.. In other words, the Atkinson index is the complement to 1 of the ratio of the Hölder generalized mean of exponent 1−ε to the arithmetic mean of the incomes (where as usual the generalized mean of exponent 0 is interpreted as the geometric mean).
This is a list of countries and territories by income inequality metrics, as calculated by the World Bank, UNU-WIDER, OCDE, and World Inequality Database, based on different indicators, like the Gini coefficient and specific income ratios.
In the framework of American federalism, states generally have wide latitude to enact policies within their borders, including state taxation and labor laws.Among the factors that may increase inequality in a state are regressive state tax policies [2] (taxation has played a growing role in diminishing inequality since the 1980s), [3] tax incentives for large companies, [4] corruption, [5 ...

Economic inequality is an umbrella term for a) income inequality or distribution of income (how the total sum of money paid to people is distributed among them), b) wealth inequality or distribution of wealth (how the total sum of wealth owned by people is ...
It's not just the top 1% that have disproportionate gains. Ratio for Each Income Percentile to Median Income In the U.S. Since 1970. The plot shows the increase in the relative gains of those above the median versus those below the median with the largest gains for those in the highest percentile.
Inequality is a state in which two or more things are not equal. In mathematics, inequality is a relation between two quantities when they are different. In other contexts, inequality is the unequal distribution of resources or rewards in an economy or society; specifically it may refer to:
The feasible regions of linear programming are defined by a set of inequalities.. In mathematics, an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions. [1]
