Questions about how to find and access data
Datasets can be found in Discover by using its facets/filters, and by entering specific information such as the study title, in the search box.
Each dataset in Discover is assigned one or more subject categories to reflect the overall subject area of the data at study level. The 'subject' facet can be used to browse our studies by broad subject area, e.g. education
Individual variables and questions can be found using the Variable and Question Bank. Coverage extends across most of the recent, major UK surveys and longitudinal studies but users should note that not all studies in the Discover data catalogue have had their variables added to this search. To check whether the survey you are interested in is covered, open up the 'Survey' filter and click 'Show more'.
Researchers, students and teachers from any discipline, organisation or country may register with the UK Data Service and obtain data. However, some datasets have restrictions on access due to the data redistribution licence agreements we have with our data providers.
