Hello, I am starting to work with DHS data and stata for the first time. I often read that DHS data must be weighted for every analyses. I am using the Namibian DHS 2013. I appended the men's file to the women's file and merged then this combined women's/men's file with the HIV file. At the beginning of my analysis I want to make some descriptive analyses. Now my question is, whether I have to weight the data for descriptive analyses of respondents background characteristics?

Following is a response from Senior DHS Stata Specialist, Tom Pullum:
If you have correctly merged the files, you will only be working with cases for which hiv03 (the test result) is not coded ".", and for those cases the correct weight to use is hiv05.
When you are checking recodes, checking data quality, doing some initial exploration of the data, you can omit the weights. Otherwise, we recommend that you use weights (in this instance, hiv05) for descriptive purposes, as well as for statistical models, because then your results will be representative of the household population.
