If you don't need the standard errors, you could try [fweight]
specification of -tabstat- and feed your sampling weights. Most of the
times, the computation of the point estimates is the same with
-fweights- and -pweights-, but standard errors are totally different,
and you really need to know what you are doing with each type of
weights.

Hello everyone,
Could someone help me on calculating quartiles from a survey data?
Specifically, I would like to run a command similar to
tabstat FVCZDJUI, by(Age2) stat(mean sd p25 p50 p75)

with survey data but don't know how.
Many thanks,
Noori
