I’m using IPUMS international, specifically for South Africa and Brazil. I’m doing household level analysis so using wthh. My questions are- which type of weight should I be using in Stata (it can not be frequency weight, because the weights are not integers). aweight? pweight?
The second question-do I still use weights in the same way when dealing with subgroups- for example, I am looking at households headed by blacks only in South Africa for some of my analysis. Does it make sense to apply the weights when calculating statistics for only this subgroup?
