Who can access the data?

Researchers, students and teachers from any discipline, organisation or country may register with the UK Data Service and obtain data. Some datasets have restrictions on access due to the data redistribution licence agreements with the data providers. Commercial use of data may also be restricted – further details are available from our How can I use data from the UK Data Service for my project?. 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. There is further information on how to obtain data in How to download and order your data.


Who can access Census data?

Census aggregate data and census flow data are available to anyone under the Open Government Licence. Only registered users are able to access some of the data, such as boundary data. Census microdata has different access conditions depending on the dataset.


Who can use Secure Lab?

Access to Secure Lab is available to researchers who fulfil all the secure access requirements for the data required:

  • To apply for access to ONS data: researchers must be an Accredited Researcher under the Digital Economy Act (DEA), and the forms required to apply for this status will be made available during the application process.
  • To apply to access for non-ONS data: researchers must be based at a UK academic institution or an ESRC-funded research centre, and be an ESRC Accredited Researcher. PhD and research students can request access but will need to apply jointly with their supervisors. However, there are a few studies which are available to other users within the UK. Please refer to the ‘Access’ tab for the relevant Data Catalogue record for details.

Note: Civil servants should continue to use the ONS Secure Research Service (SRS).
After reviewing the checklist of criteria to apply for access to Secure Lab, please get in touch if you still have queries about your eligibility.


How do I access the data?

You need to register with the UK Data Service. We use federated access management (Shibboleth) user authentication, and you will need a username and password to register.

The majority of students and members of staff at UK institutions of further or higher education will be able to use the username and password issued by their institution. There are further details in Types of data access, Registration and the Login and Registration FAQs.

You don’t need to register for access to open datasets.


What formats are the data available in?

The majority of our survey datasets are available to download in SPSS, Stata and tab-delimited (suitable for use in MS Excel) formats.

Our international macrodata are available online via UKDS.Stat or the IMF eLibrary. Data/tables can be downloaded in MS Excel and comma-separated formats.

Access to census data is via bespoke tools that produce extracts online which can then be read into a spreadsheet or mapping package using boundary data in a variety of formats.

Take a look at the Online tools for exploring data page for more details.

Qualitative data formats include MS Excel, MS Word and RTF.
There is further information about the data formats we provide at What download and data formats are available.


How do I download/order data?

Once you have registered with the UK Data Service, you will have your own account that you can access by using the ‘Login’ link on each web page.

When you have located a study in the Data Catalogue that you require, go to the ‘Access’ tab and click ‘Add to account’ or ‘Download’. Open datasets and datasets in our ReShare repository can be downloaded directly. Other datasets must be added to your account first.

When you have all the data you require in your account, you can then add the studies to a ‘Project’. If you don’t have any projects you must create one first, providing details on your intended use of the data. Projects can be ‘Non-commercial’, ‘Commercial’ or ‘Teaching’ (if you intend to use the data in a classroom setting).

Once you have added the data to a project, click the ‘Request access’ button to view the steps required to gain access to this study. Click ‘Complete actions’ to start the application process. Use the ‘Next’ button to move through the steps.

There is further information on the download process on our Download and order pages.


How do I cite data correctly?

The Data Catalogue record page of a study contains a section about citation and copyright where you can find the correct citation. You can copy and paste that information.

Best practice guidance can be found in our Learning hub.


How much will it cost?

Data required for non-commercial purposes can be downloaded, or accessed, at no cost. Charges will apply if the data are to be used for a commercial purpose. See How can I use data from the UK Data Service for my project? for further details.


Can I check the contents of a dataset before I obtain it?

Our Data Catalogue contains a full study description (Details tab) for each dataset and also provides access to online documentation (Documentation), resources (Resources tab) and access conditions (Access tab).
The Details tab provides information such as Title, Study number (SN), PID, Series, Principal investigator(s), Sponsors and contributors, Topics, Abstract, Citation and copyright, Edition history.

The Documentation tab includes user guides on how to use the data, how the data were collected, and usually the original questionnaires or topic guides. Online variable lists provide the variable names and variable and value labels.

The Resources tab provides links to related studies and publications.

Nesstar provides details for all the variables within the datasets available via the Nesstar system, which includes the full question text, frequency counts and other summary statistics.

Access to the Data Catalogue and Nesstar does not require registration, but you do need to register to conduct online data analysis or download data.


Can I obtain data from other archives?

We can help users locate data from other archives in Europe and worldwide. We can also obtain data from the Inter-university Consortium for Political and Social Research (ICPSR) in the USA for UK users – this can be done by using the ‘Special request’ option available within a registered project.

You can find data for several key international series in the Data Catalogue. You can also search for data at individual archives via the Data archives page.
