Dear DHS - User,
in my repeated cross-sectional analysis, I am using IR files for surveys between 2000 - 2018 which were conducted in countries of SSA.
Thereby, I followed the DHS sample weights procedure:
gen wgt = v005/1000000
egen stratum = group (v024 v025)
svyset [pw = wgt], psu(v021) strata (stratum)
Now, I am wondering whether - due to the svy command - I am already controlling for region-fixed effects or whether I have to include a control variable for the region (v000 v024)? It is a rather trivial question but since it is my first time working with DHS data, I wanted to kindly ask you for your advice.
Thank you very much in advance!
Warm regards,
Bianca

Following is a response from DHS Research & Data Analysis Director, Tom Pullum:
No, you do not need to adjust or control for region. The strata are usually defined by combinations of v024 and v025, but not always. The attached file: "Survey_strata.do" gives the strata for each survey. I suggest that you add "singleunit(centered)" to the svyset command to prevent a type of problem that may cause a crash.
