The Gini coefficient is a number between 0 and 1 or 100, where 0 represents perfect equality (everyone has the same income), while an index of 1 or 100 implies perfect inequality (one person has all the income and everyone else has no income).
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.
World Inequality Report is a report by the World Inequality Lab at the Paris School of Economics that provides estimates of global income and wealth inequality based on the most recent findings compiled by the World Inequality Database (WID).
Gini coefficients are simple, and this simplicity can lead to oversights and can confuse the comparison of different populations; for example, while both Bangladesh (per capita income of $1,693) and the Netherlands (per capita income of $42,183) had an income Gini coefficient of 0.31 in 2010, [72] the quality of life, economic opportunity and ...
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 ...
The adjustment of income for inequality based on the Gini coefficient was first proposed by Amartya Sen in 1976. [3] The adjustment was first applied by the UN on income data in 1993, before later being expanded to the general HDI. [4] All data is from 2013. [1]
This is a list of countries by inequality-adjusted Human Development Index (IHDI), as published by the UNDP in its 2024 Human Development Report.According to the 2016 Report, "The IHDI can be interpreted as the level of human development when inequality is accounted for", whereas the Human Development Index itself, from which the IHDI is derived, is "an index of potential human development (or ...
Compared to the Gini coefficient in practice, CV puts higher weight on the right tail of the scale, making it sensitive to the rich. Coefficient of variation may be a suitable choice of measure if the goal of a study is to analyze the wealth concentration at the top of the distribution. [17] [18]
