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 contains the census data and some life events data of approximately one million sample members, collected over 40 years. This service is free to the user.
ONS Longitudinal Study joins CLOSER
CeLSIUS is delighted to announce that the ONS Longitudinal Study is one of eleven studies to have joined CLOSER. We very much look forward to collaborating with CLOSER, which brings together world-leading longitudinal studies to maximise their use, value and impact and improve understanding of key social and biomedical challenges.
Guides to using ONS LS data
A new guide to mortality data - our final guide - is now available, along with guides to births and fertility data, defining a study population, ethnicity data, events data and socio-economic indicators.
CeLSIUS funding to 2025
We are delighted to announce that we have secured funding from ESRC to continue to support the ONS Longitudinal Study until 30 September 2025. We are currently supporting users remotely - please see below. We look forward to continuing our work with our current LS users, and to welcoming many new researchers - please get in touch via email@example.com for more information.
SRS and CeLSIUS response to COVID-19
The ONS SRS Safe Settings and UCL offices were closed in March, in accordance with government guidelines, and will remain closed until further notice. CeLSIUS is able to offer remote user support for ONS LS projects - please contact us via firstname.lastname@example.org.
LS project support will be prioritised in the following order:
New x-file (restricted variables) requests may be submitted, but ONS can only review them and cannot prepare/provide access to them. If you have already been given access to an x-file dataset, however, you will still be able to access it.
Additionally, approved researchers can apply to access their existing projects from home subject to guidelines set out by ONS on accessing secure research data as an accredited researcher.
Thank you for your patience while this remote service is in place.
