Understanding Society User Support

I am currently working on a project which is considering using Understanding Society data. Having looked extensively through your documentation I could not find any variable on the dataset indicating a respondent as the 'Household Reference Person'. On the BHPS there had previously been such a variable (wave then HG2, e.g. RHG2). Does an equivalent exist on USoc, or do you have some (SPSS) syntax or a method for deriving it?

Any help would be greatly appreciated. I look forward to hearing from you.

Best wishes,
