Make variables that are defined only for your desired subsample, e.g.
webuse nhanes2, clear
g male=sex==1 if sex<.
g mblack=black if male==1
oaxaca bpsystol weight, by(mblack) svy
* not:
oaxaca bpsystol weight, by(black) svy
* compare :
svy, subpop(male): reg bpsystol black
svy: reg bpsystol mblack
