Supporting the ONS Longitudinal Study

About the talk

We are pleased to welcome Professor Stephen Jivraj from the Centre for Longitudinal Study Information and User Support (CeLSIUS) Team, University College London and Office for National Statistics (ONS). The CeLSIUS team were winners of last year’s ONS Research Excellence Award - Secure Data Creation Award.

CeLSIUS supports academic, voluntary and public sector researchers to use the ONS Longitudinal Study (LS) in England and Wales. The ONS Longitudinal Study (ONS-LS) is a longitudinal dataset that contains census and life events data linked between six successive censuses beginning in 1971 and updated at the 1981, 1991, 2001, 2011 and 2021 Censuses.

This talk will describe the ONS-LS, the CeLSIUS support service, and examples of research using the 2021 linked data.

This presentation aligns with our February research theme: Housing & Communities.

Learn more about the Research Excellence Series

Each year, the ONS hosts a collection of online events showcasing outstanding work from across the research community. The series celebrates projects that use secure data to generate new insights and drive impact, as well as innovative organisational initiatives that strengthen research capability and collaboration.

The 2026 series will take audiences on the full journey of these projects, from inception and methodology, through to dissemination and impact. Sessions will feature a diverse range of speakers and include winners of the ONS Research Excellence Awards 2025, which recognise excellence in analysis, collaboration, secure data creation, and impactful outcomes.

The events will take place through Microsoft Teams. They will also be recorded and available to watch later, on our ONS YouTube channel.
