CeLSIUS has been supporting academic, voluntary and public sector users of the Office for National Statistics (ONS) Longitudinal Study (LS) in England and Wales since 2001. We are based at UCL and the ONS in London and are funded by the ESRC to provide free guidance and support. This includes answering initial enquiries, helping with applications to use the LS, supporting LS research projects and advising on publications and other LS research outputs.
