The Office for National Statistics (ONS) produces statistics from data which are collected from surveys.
However, it is the underlying unpublished data, provided by survey respondents, that is a valuable resource sought after by researchers and analysts from both public and non-public organisations and academic institutions.
The data may take the form of microdata (also known as unit record information), aggregated tabular data, commissioned tables, or bespoke datasets.
ONS provides a range of services through which customers can apply to gain access to these data.
Access to microdata and disclosive data, that is, data which have the potential to identify an individual record, requires the approval of the ONS Microdata Release Procedure (MRP) before the data can be provided.
Information about the different formats in which data can be obtained and details of how to apply for access can be found in each individual service's description.
For further information or advice, please contact the individual service using the contact details provided or alternatively, refer to the Access to ONS data service.
