Dividing a column by another

[Amir Moayeri]

Hello everyone,
I use the command below in Stata 17 to calculate the total income and total tax paid in each quintile (Q) and each group (Status). How can I add a column to this table calculating the tax column divided by the income column? In other words, how can I calculate the share of total tax in total income for each quintile and group?

table (Q Status)(), statistic(frequency) statistic (sum income) statistic (sum tax) statistic (percent tax) nformat(%12.0fc total) nformat(%12.2fc percent) sformat("%s%%" percent )
Thanks.

Dear Amir Moayeri

Would be much more helpful if you can provide a data example of your dataset using -dataex-
Plase, use

ssc install dataex

With an example I can better see what do you need
