The first UK Census Longitudinal Studies conference is being held at Queens University on 8th and 9th April 2019. This brings together the Northern Ireland Longitudinal Study (NILS), Scottish Longitudinal Study (SLS), and Office for National Statistics Longitudinal Study (ONS LS) for England and Wales, all based on the census, to explore their research power and develop their user base. The programme for the first day will focus on how the studies have been used and their special contribution to the UK’s population data landscape, and will consider the potential for comparative cross-UK research. There is a session for early-career researchers and posters and the programme for the first day will conclude with an international panel which will discuss how imaginative data linkage can facilitate research. The schedule for the second day gives a choice of three workshops: the first on SURE training, the second on the collective intelligence approach to impactful research, and the third on the NILS small grant research scheme – this is designed to provide seedcorn funding for research proposals using the NILS and at least one other of the UK LSs. There is no registration fee for the event.
