I am analysis a total of 40 datasets downloaded from IPMUS’s website. I read that for some countries (e.g. Mexico 2010, South Africa 2011) weights (PERWT in my case) must be used to generate representative statistics. I am using STATA which has many weighting options (fweight, iweight…) and I was wondering which one is suitable for my analysis.
In order to estimate the prevalence of disability (proportion of disabled people in the population) in South Africa, is it correct if I use the following codes: sum DISABLED [iweight=perwt]
