Doing your LS research

ONS SRS and CeLSIUS response to COVID-19

CeLSIUS staff are working from home during the pandemic, but we can offer remote user support for ONS LS projects - please contact us via celsius@ucl.ac.uk.

Please note that LS project support will be prioritised in the following order:

  1. of immediate government interest - e.g. COVID-19
  2. examined work nearing deadline (in the following three months)
  3. work only using the LS nearing study period end (in the following three months)
  4. work using the LS nearing study period end (in the following three months)
  5. ongoing work only using the LS
  6. new work only using the LS
  7. 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 in STATA 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.

Doing your LS research

Once your project has been approved, a CeLSIUS Support Officer will construct your dataset (and amend it if necessary as your study proceeds).

To maintain confidentiality of the individuals in the sample, this dataset can only be accessed from a Secure Research Service safe setting in an ONS office in London (Pimlico), Hampshire (Titchfield) or Wales (Newport). [Please see above regarding ONS SRS and CeLSIUS response to COVID-19]

To analyse your data, you may send code in STATA to be run in your absence, or discuss with CeLSIUS the outputs that you require (perhaps constructing specimen tables or models) and we will write and run code for you. Or, you may visit an ONS office and analyse your own data. Please email research.support@ons.gov.uk to book a visit in advance in case the safe setting is not available. [Please see above regarding ONS SRS and CeLSIUS response to COVID-19]

When you want interim research outputs to leave the safe setting, perhaps to work on them on your computer or to show them to other Accredited Researchers on the same project, they will be referred to as 'pre-publication' (formerly 'intermediate') outputs. To maintain the security of the LS all pre-publication outputs are checked by two Support Officers and encrypted before being emailed to users. Pre-publication outputs can only be shown to Accredited Researchers on the same project. Also, you may specify an aggregated dataset (which will have a limited number of values) as a pre-publication level output to help with your analysis outside the safe setting. Individual-level datasets will never be released.

Please note: when your project is complete, after disseminating your results, you should delete all pre-publication outputs from your computer. You may ask ONS to archive copies of your output files to be retrieved at your request at a later date.
