-svy- commands? Yes: if • You have differential non-response in identifiable subgroups, and want to compensate for that. • You want to adjust for known differences between known characteristics of the population and the sample. In that case you will want to re-weight the initially equal weights with post-stratification, or raked, weights. • You want to separate statistics for subgroups. In this case, you will not get correct standard errors without the survey commands. Otherwise, no.
