Microdata is data that can be linked to individuals, businesses and addresses. Dutch universities, scientific organisations, public policy and research institutes in the Netherlands and some other EU countries can – under strict conditions – use microdata to conduct their own statistical research. The key principles in granting access to microdata are privacy safeguards and preventing people or businesses from being exposed. All research is carried out within the CBS microdata environment.
How does it work?
1. Authorisation for institutions
Institutions require authorisation in order to access CBS microdata. The head of the institution should submit a request to this effect. The application will then be assessed by CBS, based on whether the institution's main activity is statistical or scientific research and whether it publishes data for disclosure. Here is a list of institutions that have already been authorised.
2. Project request
Applications for a research project are submitted using four forms, which include questions about the purpose of the project, the research questions and the datasets that are required. The project request is assessed for feasibility and GDPR compliance, among other things. Next, representatives from the institution are invited for a meeting with CBS experts and CBS will prepare a breakdown of the costs. The cost will depend on the number of researchers involved, the number of different datasets, the length of the project, and other factors. During the contract period, CBS will send quarterly invoices. For more information, pleases see our Services Catalogue. Once an agreement has been reached, a project contract will be drawn up, as well as a confidentiality statement for each researcher.
3. Additional services
CBS will create a project environment for you, providing access to the necessary datasets. We can also create a customised dataset for you or use your external dataset and make it linkable to the relevant CBS microdata. Various software packages can be added to the environment by mutual agreement as well, in addition to the standard software offered. For more information, please see our Services Catalogue.
4. Carrying out your project
For access to our CBS microdata environment, you will receive an explanation on . You will also need to pass am awareness test. While working on the project, you can still make some changes, such as adding researchers or datasets. Statistics Netherlands will assess the results of your research for disclosure risks before they can be published. You can read more about this in our output guidelines.
5. Publication
After your project has been completed, it will be archived and your account will be closed. The research findings based on CBS microdata must be published immediately after your research has been completed. All publications must be shared with CBS and include accurate source citations.
