We enable research using the Office for National Statistics (ONS) Longitudinal Study - the largest nationally representative longitudinal dataset in the UK

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.

Timescales of availability of 2021 LS data

ONS has provided the following update:  

Beta testing of the 2021 LS data will not start before March 2024 and the 2021 LS research database is therefore not likely to be available before the latter half of 2024. 

Please contact celsius@ucl.ac.uk if you have any queries about this.
