When to apply for microdata

If you require access to microdata for use in statistical results and analyses, including for research purposes, you need to submit an application with the relevant attachments to Statistics Norway.

The research project must be conducted in a research institution that is approved by the Research Council of Norway or Eurostat. Other institutions can apply to Statistics Norway for approval.

Public authorities, see Section 1(1) of the Statistics Act, may apply for access to microdata for statistical and analytical purposes.

New application

To obtain data from Statistics Norway, an application form must be completed and submitted along with documentation to mikrodata@ssb.no.  

All approvals must cover the entire scope of the data requested from Statistics Norway.

The following attachments must be included with the application:

  • For research projects, a research protocol or project description must be included.

  • For public administration, a description of needs and purpose must be included.

  • Attach Statistics Norway’s variable lists where these exist.

  • You could also define the population and variables in microdata.no and attach the script. Further reading.

  • If there are no variable lists, or the project includes data that are not held by Statistics Norway, this must be detailed in the application.

In accordance with the General Data Protection Regulation (GDPR), all projects that intend to process personal data must have a basis for processing. The data protection officer at your institution will be able to help you with this.

The following documentation must be attached to applications for projects with a valid and comprehensive basis for processing dating back to before 20 July 2018:

  • Recommendation from the data protection officer, licence from the Norwegian Data Protection Authority or prior approval from the Regional Committees for Medical and Health Research Ethics (REC)
  • Specification of the legal basis in accordance with the GDPR
  • Statement confirming that the project protects the privacy of data subjects in accordance with the GDPR

Projects that have a valid and comprehensive basis for processing after 20 July 2018 require either a Data Protection Impact Assessment (DPIA) or an assessment of why the DPIA is not necessary (negative DPIA).

  • Reasons for using basic statistical unit, post code, date of birth and date of death.

Application for change 

An application for change must be submitted to Statistics Norway for all changes that are beyond the scope of previous decisions on access.

Updated documentation must be attached.
