Based on my understanding, the sampling weight in DHS is provided based on the entire survey sample.
If I would like to study only a subset of population i.e. men with children.
Can the original sampling weight be applied?
Will the applied weight ensure national respresentativeness of subsetted data?

Or I will need to calculate the new sampling weights based on the subsetted data?

Hope someone can guide me for this.

Thanks :)

Yes, you can use the weights, but their sum should equal to the sample size for your subset. So you may have to rescale them. This is automatic with some commands and/or some software packages, but not all.
Best,

I have seen this in the internet regarding subsetting data.

https://stylizeddata.com/how-to-use-survey-weights-in-r/

is it appropriate to do so?
Use svydesign in R to declare surveydata and weights, then only i subset the data.
Will it fix the rescaling issue?

Following is a response from DHS Research & Data Analysis Director, Tom Pullum:

Are you asking whether it is appropriate to use weights with DHS data (it is!) or are you asking how to use weights with R? The link should provide all the information you need about the latter.
