Longitudinal studies follow the lives of individuals over a long period of time, showing us how people are affected by changes in society. The ONS Longitudinal Study (LS) contains the census data and some life events data of approximately one million sample members, collected over 40 years. CeLSIUS is funded by the ESRC to provide free support to researchers wishing to use this data.

Update from ONS on timescale of availability of 2021 LS data
The ONS previously reported that they were aiming for the updated LS research database to be available in the second half of 2024, dependent on data processing running smoothly. Unfortunately, this has not been the case and due to processing and resource issues they are having to delay the release of the 2021 LS research database until early Summer 2025. ONS apologises for any inconvenience this delay will cause and appreciates this is a significant change to the dates from those initially advertised.
