Research data policy

What should a data availability statement include?

Your data availability statement should describe how the data supporting the results reported in your paper can be accessed. 

• If your data are in a repository, include hyperlinks and persistent identifiers (e.g. DOI or accession number) for the data where available.  
• If your data cannot be shared openly, for example to protect study participant privacy, then this should be explained. 
• Include both original data generated in your research and any secondary data reuse that supports your results and analyses.

Read our detailed guidance on how to write an excellent data availability statement.

Citing data sources

You should cite any publicly available data on which the conclusions of the paper rely. This includes novel data shared alongside the publication and any secondary data sources. 

Data citations should include a persistent identifier (such as a DOI), should be included in the reference list using the minimum information recommended by DataCite (Dataset Creator, Dataset Title, Publisher [repository], Publication Year, Identifier [e.g. DOI, Handle or ARK]) and follow journal style.

See our further guidance on citing datasets.
