Re: st: tabulate or other command?

Thanks Brian, but I think that I have expressed my question wrong.

The idea is to calculate the total person for each code.
For ex
id postcode region
1   1        2
1   1        2
1   2        2
1   3        2
2   1        4
3   1        5


So I have 3 people in postcode1 1 in postcode 3 and 1 in postcode2.
if use tab the result is 4 obs with post code 1, but I have only 3  
people, so because id
is not unique.
Thanks a lot.
