The Wealth Gini coefficients from 2008 are based on a working paper published by the National Bureau of Economic Research. [5] The Wealth Gini numbers for 2018, 2019, and 2021 come from the Global Wealth Databook by Credit Suisse. [6] [7] [8] * indicates "Wealth inequality in COUNTRY or TERRITORY" or "Income inequality in COUNTRY or TERRITORY ...
In economics, the Gini coefficient (/ ˈ dʒ iː n i / JEE-nee), also known as the Gini index or Gini ratio, is a measure of statistical dispersion intended to represent the income inequality, the wealth inequality, or the consumption inequality [2] within a nation or a social group.
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. Income from black market economic activity is not included.
Map of Gini coefficients by US state, 2019. The Gini coefficient is a measure of inequality of incomes (or sometimes wealth) across individuals. A score of "0" on the Gini coefficient represents complete equality, i.e. every person has the same income.
The Gini coefficient is a widely accepted statistic that applies comparisons across jurisdictions, with a zero indicating perfect equality and 1 indicating maximum inequality. Further, various public and private data sets measure those incomes, e.g., from the Congressional Budget Office (CBO), [ 2 ] the Internal Revenue Service, and Census. [ 8 ]
Gini: Higher Gini coefficients signify greater inequality in wealth distribution. A Gini coefficient of 0 reflects perfect wealth equality, where all wealth values are the same, while a Gini coefficient of 1 (or 100%) reflects maximal wealth inequality, a situation where a single individual has all the wealth while all others have none.
For example, the Gini coefficient for wealth inequality increased from 0.80 in 1983 to 0.84 in 1989. In the same year, 1989, the Gini coefficient for income was only 0.52. [56] The Gini coefficient is an economic tool on a scale from 0 to 1 that measures the level of inequality. 1 signifies perfect inequality and 0 represents perfect equality.
This is list of countries by their inequality adjusted income, as defined and measured by the United Nations Development Programme. [1] The income index is one component of the Human Development Index, but is also used separately. [2] The adjustment of income for inequality based on the Gini coefficient was first proposed by Amartya Sen in 1976 ...
