How does CBS handle your privacy?

Your personal data are safe with CBS. Individual persons are never identifiable or traceable in our statistics and publications. We also have measures in place to prevent theft, loss or misuse of personal data. CBS will never supply identifiable data at personal level to third parties, including other government institutions.

CBS protects your data with technical measures. In addition, data are protected under the organisation’s internal regulations. Following are the most important measures:

  • When you complete a survey or submit any data, this information is delivered to CBS in encoded form. At CBS, the data is then stored in a secure environment. Only properly authorised employees are granted access to this data. This happens when their work requires direct access.
  • Personal data will be removed from the files as quickly as possible. This means researchers do not see any data such as names, addresses or citizen service numbers (BSN) in the files.
  • Every CBS employee is required to observe the confidentiality obligation. Each employee signs a non-disclosure agreement to this effect.
  • CBS only uses the data for the purpose of statistical production and scientific research. Use of the data for any other purpose is excluded by law. In other words, CBS never uses the data for investigations, tax inspection, legal matters or marketing and advertising.
  • An independent body checks whether CBS complies with all privacy-related regulations and agreements.

About CBS

CBS responds to developments in Dutch society by providing statistical information as facts that matter, and communicates on these facts with the outside world. In doing so, CBS offers insights into current developments in society and helps answer policy questions. Research at CBS is focused on broad trends in society and how these are interrelated.

CBS has offices in The Hague, Heerlen and Bonaire with altogether approximately 2,000 staff. A society-oriented working attitude is essential to CBS. CBS provides figures which are relevant to society. Every year, CBS publishes around 600 statistical studies. Virtually every day, CBS data and figures are communicated to the outside world via news releases, video messages and through social media. This results in some 50,000 articles per year in daily newspapers and on news sites.
