Beginning in SAS 9.2 TS2M0, if you have a stratified survey design and wish to compute summary statistics within each stratum, you can specify the strata variable(s) in a DOMAIN statement in PROC SURVEYMEANS. For example:

      proc surveymeans data=dsn;
        var y;
        strata str;
        domain str;
        weight w;
        run;
