Hi,
I was wondering if there was any guidance on university students in the sample. Are these generally considered as moved to a new household, if they are away for only part of the year? Are interviews conducted with university students who are living remotely on campus? Or is there a lower chance that university students would be included in the surveys since they are away from 'home'?
I haven't found much previous UKHLS work that focussed specifically on university students, so I'm wondering if there are some methodological reasons for this.
