Declare the complex survey design like:
proc surveyfreq; stratum STRATUM; cluster CLUSTER; weight WEIGHT; table VOTE PARTY VOTE*PARTY ; run;
Or:
svyset CLUSTER [pweight=WGT], strata(STRATUM) vce(linearize) singleunit(centered)
Until the 2006 pilot, clusters and strata were published as a single variable. This could be broken apart like:
compute STRATUM = trunc(v040103/10). compute CLUSTER = v040103 ‐ (10*STRATUM)
