Following is a response from Senior DHS Stata Specialist, Tom Pullum:
As you may know, "_n", or "underscore n", is assigned by Stata to be the ordinal number of the case in the file you are currently using. That is, if you have N cases, then the first case has _n=1, the second case has _n=2, the last case has _n=N, etc. For most purposes, if you want to use or save that number, you have to give it another name, for example with "gen id=_n".
What you want in that position of the svyset command is the cluster variable. You can use v001 or v021 for that purpose. They are always (so far as I know) exactly the same. That's how to include the cluster adjustment.
Thus, instead of "svyset _n [pweight=v005], vce(linearized) singleunit(missing)", you probably want "svyset v001 [pweight=v005], vce(linearized) singleunit(missing)".
