The Gini coefficient has also been applied to analyze inequality in dating apps.[99][100]. The Gini coefficient can then be thought of as the ratio of the area that lies between the line of equality and the Lorenz curve (marked A in the diagram) over the total area under the line of equality (marked A and B in the diagram); i.e., G = A/(A + B). Economist David Giles argued that the standard error of the estimate of A can be used to derive the estimate of G directly without using a jackknife. y = Another limitation of the Gini coefficient is that it is not a proper measure of egalitarianism, as it only measures income dispersion. ) Guillermina Jasso[38] and Angus Deaton[39] independently proposed the following formula for the Gini coefficient: where When men and women are considered together, the Gini coefficient-based Shorrocks index trends imply long-term income inequality has been substantially reduced among all workers, in recent decades for the United States. And the Gini decrease: i ( n) = i ( n) p l i ( n l) p r i ( n r) So, for this example with 110 observations on a node: https://en.wikipedia.org/w/index.php?title=Gini_coefficient&oldid=1133007475, This page was last edited on 11 January 2023, at 20:46.
