Questions about how to find and access data
Datasets can be found in our Data Catalogue using its search box and by using/clicking on its filters/facets (Topic, Data Type, Access, Country).
When you enter terms you want to search for, such as ‘health’, or ‘energy prices’, a list with strings and keywords will appear while you are typing.
Each study has been indexed using keywords which represent concepts used in social science research. The keywords are taken from our electronic HASSET thesaurus.
Spaces between words are interpreted as AND by default.
You can also use the Boolean operators OR, or NOT for complex searches.
There is also a link to our Variable and question bank and to our Qualibank.
You can use filters/facets to narrow down your search. For example, searching for ‘energy prices’ and filtering on the topic ‘health’ reduces the list of results and displays only those studies about energy prices in the topic area ‘health’. The same goes for the other filters Date from/Date to, Data Type, Access and Country.
Each dataset in our Data Catalogue is assigned one or more topic categories to reflect the overall topic area at study and series level. The 'topic' facet can be used to browse our studies by broad subject area, e.g. education or society and culture.
You can find individual variables and questions using the Variable and Question Bank. Coverage extends across most of the recent, major UK surveys and longitudinal studies but please note: not all studies in our Data Catalogue have had their variables added to this search. To check whether the survey you are interested in is covered, go to Variable and Question Bank (link is at the bottom of the search box), open up the 'Survey' filter and click 'Show more'.
You can sort your results by choosing a sorting order: most recently published studies, relevance, alphabetical order of the titles, and reversed alphabetical order of the titles.
For further details, click on the title of a study. This brings you to the Data Catalogue record which contains very detailed information (Details tab) about the Title, Study number (SN), PID, Series, Principal investigator(s), Sponsors and contributors, Topics, Abstract, Citation and copyright, Edition history. The Data Catalogue record also contains information about the documentation, the resources and access conditions.
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. Commercial use of data may also be restricted – further details are available from our Commercial users page. Details of the access conditions that apply are available in the individual records in our Data Catalogue: clicking on the title of the study/series takes you to the Data Catalogue record, then the Access tab.
You can use the filter Access to get an overview of datasets that are open, safeguarded or controlled.
