For a longitudinal Study like SHARE, a compilation of a preload database is essential. Preload data are data which come from a previous wave of data collection and are loaded in the Sample Management System to steer the survey instrument of a new wave. The preload database includes mainly demographic information, interview status, information on household composition, eligibility status and selected content information. This project is about conceptualisation and compiling of the preload file. Conceptualisation is repeatedly necessary due to questionnaire changes affecting the set of variables to be preloaded. This needs to be done in close coordination with CentERdata. Thereafter, program routines have to be adapted accordingly to compile the preload data for all countries and all data collection phases (pretest, field rehearsal and main data collection). For this we also need input from survey agencies. We process and include information provided by survey agencies in our correction routines and preload programs to generate a proper preload file.
