I don't know which CPS data set you are using. However without using Stata's survey commands you will not get correct standard errors. CPS supplies jackknife replicate weights for computing standard errors and you must identify them in a -svyset- statement, as at http://cps.ipums.org/cps/repwt.shtml. In general you would use pweights for survey sampling, but cps.ipums page specifies an [iweight=] statement, because the weights can be negative. If you do not use the replicate information than all of your standard errors will be incorrect.
