		Hi, 
I wish to calculate proportion of stunted children for the micro-level administrative units like district and sub-districts with their standard errors. I followed the usual method of complex survey method in SPSS. The problem I found that for the sub-population having single cluster the design effect is zero and also the standard error is zero. The SPSS plan code is given below. 
 
 
COMPUTE WGT=V005/1000000. 
EXECUTE . 
 
* Analysis Preparation Wizard. 
CSPLAN ANALYSIS 
  /PLAN FILE='C:\Users\dell\Downloads\BDHS2011.csaplan' 
  /PLANVARS ANALYSISWEIGHT=WGT        
  /SRSESTIMATOR TYPE=WR 
  /PRINT PLAN 
  /DESIGN STRATA=V023 CLUSTER=V001  
  /ESTIMATOR TYPE=WR. 
 
 
May be I need the exact way for obtaining the standard error. If I avoid the sample design and use sampling weight only, I obtain the same estimates as I found using sampple design but the standard error is not now zero. Thus the issue is the design effect for the small sub-population. Is there any way to avoid such computation problem.  
 
If I am working correctly and the results are theoretically reasonable, can you please inform me the exact reasons. 
 
If there is any other technique, please suggest e hw can I solve the problem. 
 
Regards,

Following is a response from Senior DHS staff member, Tom Pullum: 
 
A standard error is calculated for an estimate, such as the estimated mean value of an indicator.  The procedure to calculate a standard error is the same for any subpopulation (unless you use Bayesian methods for nested populations).   
 
Are you trying to match a number in a DHS report?  Are you interested in some specific indicator?
