Access to register data?

As a researcher, you can gain access to the Danish registries at Sundhedsdatastyrelsen and Statistics Denmark.


Sundhedsdatastyrelsen  is responsible for different health registries which contain data related to the health of the population  and the services of the health system.  Statistics Denmark also offers access to the individual health registries but also to data on demography, socio-economic data (e.g. income and level of education), labour data, social data and data on accommodation and estate on personal level.


The difference between Sundhedsdatastyrelsen and Statistics Denmark

The two main differences between Sundhedsdatastyrelsen and Statistics Denmark are:

  • Sundhedsdatastyrelsen contains the newest data of the big health registries (Statistics Denmark are behind by aprox. one year)
  • Only at Statistics Denmark, you can access socio-economic data

OPEN Registry will guide you to more differences and to what is most relevant to your project.


To access register data at Sundhedsdatastyrelsen or Statistics Denmark, you need to apply through a research unit which holds an authorisation. OPEN will help your apply for an authorisation for Sundhedsdatastyrelsen or Statistics Denmark for your research unit, if you do not have one already.


Costs at Sundhedsdatastyrelsen and Statistics Denmark

Costs regarding data extraction from external registries at Sundhedsdatastyrelsen and Statistics Denmark will be held by the research project.
