A possible solution might be the -somersd- package, which can be downloaded
from SSC and which can calculate confidence intervals for Gini coefficients
(which are a special case of Somers' D). The package includes a manual
-somersd.pdf-, which contains an example of the use of -somersd- to
calculate Gini coefficients with frequency weights.
I hope this helps.

Hello,
I have a problem regarding Gini Coefficient. I have data like this
region population income(total) income
source1 income source2
Beijing 1072 2000 1500 500

I want to calculate the Gini coefficient weighted by population. And I
want to decompose the contribution of each resource to the Gini
Coefficient. So which ado file I shoule use in STATA and how about the command?
I used inequal, and used command "inequal income(total)", but it seems
that it just calculated the gini index and did not take the population
into consideration. So could you help me?
Thanks very much!!
yours
Di Han
