Subject:      Survey data analysis

Dear SAS-L experts,

I am trying to calculate the difference of variables of interest between 2 years of survey data. I have proc surveymeans in SAS and I also have a SAS compatible sofeware SUDAAN that specifically for survey analysis (never used). Now my question is how should I lay out the data? stack them with indicator of year 1 and 2? or put them side by side and calculate the differences first, then use proc surveymeans? I hate to do the 2nd way if I can avoid to do it. Any advices?

Thanks in advance.
