Hi,

I have individual data (see below) where r101 is the province code, r401 is Person ID, r403 is each person's relation to household head (1 = HH head, 2 = spouse, 3 = child, etc), and r601 is the person ID of each person's mother (similar to r403). I'd like to generate Household ID (hhid) given the PID. E.g. Row 1 - 7 is one family, so the hhid = 1. Row 8 - 9 is one family, so the hhid = 2. Row 10 - 14 is one family, so the hhid = 3. Does anyone have any idea on how to do such a thing?
Thank you!
