What's the study design and purpose, Daniel? Even if you don't have survey sample data, you can use -svy: tabulate- ******************************* sysuse auto, clear svyset _n [pw = trunk] //_n means primary sampling unit is individual observation svy: prop rep78 // no need for [pw = ] option svy: tabulate rep78, se ci svy: tabulate rep78 foreign, col se ci ************************* If you _do_ have survey sample data, then -svyset- according to the design. Note that 'pw' = 'probability weight', which reflects probability of selection and, informally, is the number in the population represented by each sampled observation.
