Data Availability Statements are brief statements about whether the authors of an article have made the materials supporting their findings available, and if so, where readers may access them. They help to promote transparency and reproducibility in research, and to increase the visibility of valuable data and other materials produced during the course of research.

As part of our commitment to supporting open research, some of our journals now require all manuscripts to include a Data Availability Statement in order to be accepted for publication.

Does this mean I have to make all my data publicly available?

No. We encourage all authors to make data available when possible, but a Data Availability Statement simply needs to state whether you have made materials available, and if so, where and how they can be accessed.

If your journal has additional requirements related to data sharing, these will be specified in the journal’s instructions for contributors.

What counts as “data”?

“Data” is interpreted in the broadest sense to mean any evidence or resources that would be necessary for others to fully evaluate the basis for your findings, and to verify or reproduce your work. This includes raw or processed data sets, code, and protocols, as well as qualitative resources such as images, audio, video, maps, interview transcripts, field notes, and public reports. It also includes any information necessary for others to access, interpret and process these resources.

What should I write in a Data Availability Statement?

The table below gives some illustrative examples.
