st: Calculating percentages (proportions) of indicator variables

[rado645-bg@yahoo.de]

Dear all,

I hope that you would help me with the following technical problem.


I have a dataset based on a question with four different possible answers. The 
question takes the form of an indicator variable with 4 different numeric values 
(1,2,3,4).

I have data for individuals from several countries.  I need to generate a new 
variable that contains the fraction (i.e. percentage share) of each response  to 
the question within each country. However, I cannot find any online source on 
calculating percentages with mutliple responses in Stata (more than two).

Example:

country: response:

1               3
1               3
1               2
1               1
1               4
1               3
2               1
2               1
2               2
2               3
2               4
3               2
3               2
3               4
3               3
3               1
