How are concentration indices used to measure inequality?
Concentration indices can also be used to indicate health inequality. They use a similar methodology to Gini coefficient and control for the socioeconomic dimension of health ( Peterson, 2014 ).
How are income inequalities related to regional inequality?
This paper provides a new dataset of regional income inequalities within countries based on satellite nighttime light data. First, we empirically study the relationship between luminosity data and regional incomes for those countries for which regional income data are available.
How is the Theil index used to measure inequality?
However, the Theil index does not have a straightforward representation and lacks the appealing interpretation of the Gini coefficient ( Coudouel et al., 2002 ). A Pen’s Parade graph can be useful in showing how incomes, and income distribution, change over time.
Which is the best study of income inequality?
The Luxembourg Income Study (LIS) calculates income inequality statistics for a small number of richer countries ( Solt, 2009 ).
Concentration indices are frequently used to measure inequality in one variable over the distribution of another. Most commonly, they are applied to the measurement of socioeconomic-related inequality in health. We introduce a user-written Stata command conindexwhich provides point estimates and standard errors of a range of concentration indices.
What is the definition of the concentration index?
Background The concentration index is defined as twice the area between the concentration curve and the diagonal.
How is the command used to graph concentration curves?
The command also graphs concentration curves (and Lorenz curves) and performs statistical inference for the comparison of inequality between groups. The article offers an accessible introduction to the various concentration indices that have been proposed to suit different measurement scales and ethical responses to inequality.
