I have given this a try. The two sets of code should give the same results. Note however that I find it much easier to work with -svy:mean- rather than -svy:prop- but this requires your variable of interest to be coded 0/1. You would need to install Roger Newson's -parmest- (SJ, etc.). clear sysuse auto gen subgroup = 0 replace subgroup=1 if _n>15 statsby _b _se, by(rep78) saving(R:\tot.dta,replace):proportion foreign statsby _b _se, by(rep78) saving(R:\subgroup.dta,replace):proportion foreign if subgroup==1 clear use R:\tot.dta append using R:\subgroup.dta clear sysuse auto gen subgroup = 0 replace subgroup=1 if _n>15 gen wgt=1 svyset [pweight=wgt] parmby "svy: mean foreign,over(rep78)",saving("R:\tot.dta",replace) ev(_N _N_subp V_db) em(depvar) es(N) ylabel parmby "svy,subpop(subgroup): mean foreign,over(rep78)",saving("R:\subgroup.dta",replace) ev(_N _N_subp V_db) em(depvar) es(N) ylabel clear use R:\tot.dta append using R:\subgroup.dta I may have misunderstood what you are trying to do but maybe this will help.

Various other approaches e.g. Roger Newson's -parmest- (SJ, etc.), or so I imagine.
