Data Sharing


We are committed to maximizing the use of Whitehall II data to advance scientific knowledge. 

We welcome proposals for collaborative and non-collaborative projects for bona fide research. We make data as widely and freely available as possible while strongly protecting confidentiality, and making sure that we maintain the reputation of the study, its funders and its participants.

For aggregate data, please contact the researcher you wish to collaborate with.

For individual-level data, we follow a controlled access model for sharing, which is described in our Whitehall II data sharing policy (PDF). This policy conforms to the MRC Policy on Research Data Sharing

For general data sharing enquiries, please contact Dr Aida Sanchez.
For projects involving genetics, please contact Dr Meena Kumari

Applying for data

For individual level data, please submit the following two documents:

  1. the WII Data Sharing Application Form (rtf, also in PDF).
  2. the WII Excel data dictionary with the list of variables needed for the project. Please highlight only the variable names needed for your project.

The WII research team meets monthly to evaluate all applications received. Upon approval of an application, applicants will be asked to sign the WII Data Sharing Agreement (last page of application form).

Within two weeks of the receipt of this document, the data manager will release an anonymised dataset, tailor-made for each project.

For aggregate data, please contact the researcher you wish to collaborate with.

Data Documentation for phases 1 to 9

You can obtain a detailed description of the WII variables in the following sources:

- Excel data dictionary

- Questionnaires

- Clinical Measures

On request, we can supply documentation such as copies of other WII questionnaires (FFQ, MMSE, GKQ, cortisol diaries, etc), clinical protocols and syntax of derived variables.

Data sharing in numbers

Over the last 10 years, the Whitehall II study has released aggregate and individual-level data for many research projects, including a large number of international consortia.

Up to end of 2016 we received 192 data sharing applications (Excel file) for individual level data. Many of these applications were for external projects, ie, not involving authorship of Whitehall II researchers.
