How to use the LS

It is the ONS' policy that the LS be used as easily as is consistent with maintaining the confidentiality of the data. The necessity for confidentiality means that all analysis of individual records must take place on the ONS computer and only statistical abstracts or tabulations can be released to the user. To ensure this, ONS monitors both requests to use the LS and the resulting analysis.

For this reason formal channels have been established for requests for access to the LS for research purposes, and two teams of support staff have been identified to assist users: the ONS LS Unit and CeLSIUS.

Potential academic and governmental users (i.e. those working or studying in the UK Higher Education sectors or government offices) are assisted and supported by the CeLSIUS team. ONS are currently implementing a new LS access procedure, please contact celsius@ucl.ac.uk if you are a current LS researcher and would like to become an Accredited Researcher, or someone who would like to start a new LS project.

Other users should contact the LS team at the ONS.

Where are the data accessible?

The LS databases are kept under high security at ONS. Only ONS or CeLSIUS staff can directly access the LS databases to produce data extracts. If you are staff or student in a UK higher education institution or governmental organisation, CeLSIUS staff can extract your data, run your analyses and release results to you. These results will be in the form of tabulations, models or aggregated datasets; individual-level data is never released.

Alternatively, users can go to ONS to analyse individual-level data directly. ONS or CeLSIUS staff will extract a dataset suitable for your purposes which you can analyse in the ONS office in Pimlico, London. It may be possible for users to visit ONS offices in Titchfield (Hampshire) or Newport (Wales) instead, but this is not guaranteed. Results which can be released from any ONS office will be subject to the same constraints as mentioned above - they may be tabulations, models or aggregated datasets but not individual-level data.

In both ways of working the process is iterative and fresh extracts can be made or fresh analyses carried out, as your research ideas develop.

How do I find out about the variables in the LS?

Most researchers begin by checking the questions asked in the census forms. The 2,800 plus variables available in the LS, up to and including the 2011 Census, are described in this online data dictionary. Additionally, CALLS-Hub have provided a dictionary that contains variable from across the UK LS'

The "metadata" (information about data) in the data dictionary include details of the range of each variable and relevant references to the LS Technical Volume (LS series no. 7) and other publications on the source and quality of the data.
