Data access statements

Data access statements are used in publications to describe where supporting data can be found and under what conditions they can be accessed. Examples are given at the bottom of the page.

Why do you need a data access statement?

Data access statements are required for all publications arising from publicly-funded research. They are a requirement of many funders' data policies and are a requirement of the UKRI (Formerly RCUK) Policy on Open Access (pdf, Section 3.3 ii). Sometimes they are called data availability statements.

Some funders have indicated that they now check for the inclusion of data access statements in publications that acknowledge their support. In particular the requirement applies to all papers that acknowledge EPSRC funding with a publication date after 1 May 2015 (see our EPSRC guide).

Also, some journals encourage or require data access statements, for example PLOS or Springer Nature.

Does this mean all data needs to be published?

The aim of the data access statement is discoverability — the data referenced by the statement do not have to be openly available. There are many reasons why access to data should be restricted and if you are unsure about whether you should publish your data openly please contact for advice.

Where to provide the data access statement?

We recommend one of the following options:

  1. Some journals (for example PLOS) now provide a separate section in articles for the data access statement.
  2. You can include the data access statement with the acknowledgement of funder support.

If these options are not available you can include a data statement in your main reference section. Please email if you have any questions.

What to include in the data access statement?

Depending on if your data is openly available or not one of the following options will apply:

  • If data are openly available the name(s) of the data repositories should be provided, as well as any persistent identifiers or accession numbers for the dataset. The data repository could be Pure or an external data preservation archive.
  • If there are justifiable legal or ethical reasons why your data cannot be made openly available, these should be included in the data access statement. In this case, the data access statement must direct users to a permanent record that describes any access constraints or conditions that must be satisfied for access to be granted. You can do this in Pure.
  • If you did not collect the research data yourself but instead used existing data obtained from another source, this source should be credited.

 Please note that a simple direction to interested parties to contact the author would not normally be considered sufficient.

 When should I deposit data in order to get a DOI for my Data Access Statement?

The problem is that the paper has to reference the DOI of the dataset, but once a dataset has been given a DOI you cannot change the dataset. Therefore we recommend the following steps:

  1. In your draft paper's Acknowledgements, include a sentence like "The underlying data in this paper is available from" as it goes through the journal reviewing process.
  2. When the paper is accepted, generate and deposit the dataset. You will need to edit the paper's text to give the dataset DOI that you will receive from the Library when the dataset is validated. This version of your paper is the AAM (authors accepted manuscript), which you will also need to deposit in Pure to satisfy HEFCE's open access requirements.
  3. When the paper finally appears in print or online, update the dataset metadata to give the full details of the paper, including its DOI.

Commercial restrictions

"Supporting data will be available from Lancaster University research portal at after a 6 month embargo from the data of publication to allow for commercialisation of research findings."
