Editing Gini coefficient (section)

===Income Gini can conceal wealth inequality===
A Gini index does not contain information about absolute national or personal incomes. Populations can simultaneously have very low income Gini indices and very high wealth Gini indexes. By measuring inequality in income, the Gini ignores the differential efficiency of the use of household income. By ignoring wealth (except as it contributes to income), the Gini can create the appearance of inequality when the people compared are at different stages in their life. Wealthy countries such as Sweden can show a low Gini coefficient for the disposable income of 0.31, thereby appearing equal, yet have a very high Gini coefficient for wealth of 0.79 to 0.86, suggesting an extremely unequal wealth distribution in its society.<ref>{{cite journal|title=Inequality Trends in Sweden 1978–2004|first1=David|last1=Domeij|first2=Martin|last2=Flodén|journal= Review of Economic Dynamics|volume=13|issue=1|year=2010|pages=179–208|doi=10.1016/j.red.2009.10.005|citeseerx=10.1.1.629.9417}}</ref><ref>{{cite web|title=Accounting for Swedish wealth inequality|first1=David|last1=Domeij|first2=Paul|last2=Klein|date=January 2000|url=http://fmwww.bc.edu/repec/es2000/0883.pdf|archive-url=https://web.archive.org/web/20030519155531/https://www.econometricsociety.org/meetings/wc00/pdf/0883.pdf|archive-date=May 19, 2003}}</ref> These factors are not assessed in income-based Gini.
