Hello Austin and Robert, thank you for your solutions. I'm sure they would work, but I have a very large dataset, so Austins solution would take hours, and for Roberts solution I would have to use SSC. But another Stata user sent me this solution: Von: "Fernando Rios Avila" <f.rios.a@gmail.com> Gesendet: 06.07.2011 15:18:00 An: "'Hans Meier'" <mr.hans.meier@web.de> Betreff: RE: st: Creating household id for groups of persons >Hi Hans, >I was playing around with a very small sample similar to yours, and come up with this small code. >Here hid3 would be the household id code. > > egen hid1=group (contract) > bysort id: egen hid2=min(hid) > bysort contract:egen hid3=min(hid2) > >Hope this is what u were looking for. >Best It works perfect, and very fast.
