Following is a response from Senior DHS Stata Specialist, Tom Pullum:
Regarding your second question, we do not have the sampling fractions or weights for households within clusters. The weight we provide is for the combination of sampling clusters and sampling households within clusters. There have been several earlier posts on this.
Regarding the first question, if you open the PR file and enter "tab1 hv117 hv118" you will see that this survey subsampled only half of the men. When you combine with women, you need to approximately double the weight for the men.
The following routine will calculate the correct weight for the men relative to the women
use e:\DHS\DHS_data\PR_files\NGPR6AFL.dta, clear
* Reduce the PR file to men who are eligible by age and are de facto
keep if hv105>=15 & hv105<=49
keep if hv103==1
keep if hv104==1
* Total hh weight for men who are eligible by age and are de facto
summarize hv005
scalar W=r(sum)
* Total hh weight for men who are eligible by age and are de facto and are subsampled
summarize hv005 if hv104==1 & hv118==1
scalar W1=r(sum)
* Calculate the ratio
scalar factor=W/W1
scalar list factor
use e:\DHS\DHS_data\MR_files\NGMR6AFL.dta, clear
* Multiply mv005 by the ratio and round to an integer
gen mv005_rewtd=round(mv005*factor)
* Then append the IR and MR files and use mv005_rewtd as the weight for men
