Data access

Access data from NDPH studies

We welcome requests from researchers who wish to access data from the department's major cohort studies, and aim to ensure that the information we have collected is used as widely as possible in order to maximise the value of these data for public health. Researchers may request access to raw data, summary tables and analyses that have not been released in publications or through online repositories. 

You may request access to data in one of the department's major cohort studies by following the links below.
