Using the ONS Longitudinal Study
ONS Longitudinal Study data is available for free to researchers who can show that their work is in the public interest. The confidentiality of the individuals in the LS data sample is of paramount importance, however, so researchers must apply to use the data.
ONS SRS and CeLSIUS response to COVID-19
In normal circumstances, the data can only be accessed within ONS SRS Safe Settings at ONS offices in London, Newport (South Wales) and Titchfield (Hampshire). However, because of the COVID-19 pandemic the Safe Settings were closed in March 2020, in accordance with government guidelines, and will remain closed until further notice. CeLSIUS staff are working from home during the pandemic, but we can offer remote user support for ONS LS projects - please contact us via firstname.lastname@example.org.
Please note that LS project support is currently being prioritised in the following order:
- of immediate government interest - e.g. COVID-19
- examined work nearing deadline (in the following three months)
- work only using the LS nearing study period end (in the following three months)
- work using the LS nearing study period end (in the following three months)
- ongoing work only using the LS
- new work only using the LS
- other work
Please also note:
We are accepting and processing new applications to use the LS but we estimate that, from application submission to final approval, you should allow at least four months. Also, support for these once they are approved will be limited for the time being.
Large scale cross tabs and other work involving extensive manipulation to prevent disclosure will not be cleared.
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. If your organisation has an Assured Organisation Connectivity (AOC) agreement with ONS, please submit a homeworking request.
If necessary, you may send code to be run by us for you, or you may discuss with us the outputs that you require (perhaps constructing specimen tables or models) and we will write and run code for you. Also, you may specify an aggregated dataset (which will have a limited number of values) for you to analyse at your place of study/work.
Thank you for your patience while this remote service is in place.
