my name is Daniele Guariso and I am a PhD student in Economics at the University of Sussex. For my research I am using the 6th wave of Understanding Society, but I would like to have some clarifications regarding how the survey was conducted. Were the self-completion questionnaires filled the same day as the one when the household's interview took place? And what is the difference between the household grid and interview date?
Thank you in advance for your clarification.
