Thank you Steve,
Does that mean that if I want to get population estimates (with large standard errors of course) I have to normalize the weights to the population size as reported on the country final report?

According to the DHS Recode Manual (http://www.measuredhs.com/pubs/pdf/DHSG4/Recode1DHS.pdf), the weights are standardized to sum to sample size. You should be very familiar with this manual.

This is a question to anyone who has some familiarity with the DHS survey.

I am trying to use dhs survey data in stata, but am unsure on how to
parametrize it correctly,

So far, using the household members recode file, I have done the following

pweight: w3
VCE: linearized
Single unit: missing
Strata 1: hv022
SU 1: hv021
FPC 1:<zero>

where w3=hv005/1000000

Under this parametrization, when I issue an "svy: tab" command for any
variable, Stata reports a population size very similar to the number
of observations. This seems a little strange to me. I am doing
something wrong?

I would really appreciate your help.

Regards

Michele
