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.

Thank you all guys.
prop RRACE [pweight = RWEIGHT] and
tabulate RRACE [weight = RWEIGHT]
are both what I am looking for.
Thank you,
Daniel
