Microdata access conditions
General conditions

Data can be accessed for research, teaching and analysis purposes.

Conditions for non-resident researchers

Same as for national researchers.

Conditions for students

Same as for confirmed researchers, if working under the supervision of a tutor.

How to apply & modes of access
Public Use Files

A growing number of files are made available from the website of ONS.

Scientific Use Files

Highly anonymised files are available from the UK Data Service (UKDS) acting as agent for ONS. Registration is required and the user must sign an End User Licence. The data can be used only for research, teaching, or personal educational development.
More detailed data are also available from UKDS. Registration is required and the user must sign an End User Licence or, in cases in which data are more detailed or more sensitive, Special Conditions or even a Special License. Some data files are only accessible to users affiliated to institutions belonging to the UK Access Management Federation.

Secure Use Files

Available in onsite and remote secure environments from both ONS (through its Virtual Microdata Laboratory, VML) and to some extent UKDS (formerly SDS, Secure Data Service; now Secure Lab). Users must: i) apply to become an ONS-Approved or (for UKDS) an ESRC- Accredited Researcher; ii) complete a User Agreement, and iii) attend training.
ONS and other partners are currently setting up four Administrative Data Research Centres for England, Wales, Scotland and Northern Ireland. These centres aim to develop new linked data collections from administrative sources, provide access to them, make sure they are used safely and effectively, and develop research capacity. The England centre is expected to open in autumn 2014.
