How does CBS collect data?
CBS collects as much information as possible from existing government and business registries. The use thereof is regulated by law, with top priority given to privacy and reliability. Additionally, CBS collects data through its own surveys. New data sources such as big data are also increasingly forming the basis for statistics.
Three quarters from registers
Three quarters of the figures collected and analysed by CBS come from registers of other authorities, such as the Personal Records Database, the Tax and Customs Administration, the Employee Insurance Agency (UWV), the national police and the Social Insurance Bank (SVB). CBS’ statutory task is to compile and publish the statistics that are needed.
Ten percent of the figures are collected from businesses and citizens. This is done by means of surveys conducted either online, by phone or face-to-face, by means of so-called ‘smart surveys’ via an app on mobile phones, or sensors for example in smartwatches that measure certain activities of people for the time-use survey.
CBS is also increasingly working with new techniques to obtain information, constituting about 10 percent of the total. To this end, CBS uses artificial intelligence techniques such as web scraping and text mining to collect data from the internet and scanner data from supermarkets to determine consumer prices. New data sources such as traffic loops, social media and payment data provide about 5 percent of the information.
Combining all these data sources in an innovative and reliable way creates greater possibilities to produce new, up-to-date, society-oriented and more detailed statistics.
Facts that matter
CBS stands for a well-informed society, based on facts. As the designated statistical office of the Netherlands, CBS supplies reliable statistical information relevant to social issues. In doing so, CBS contributes to social debate, research, policy development and decision making. We have been doing so since 1899.
Sticking to the facts:
- 600 statistical surveys per year
- 2 thousand highly educated staff, working together from The Hague, Heerlen and Bonaire
- 70 thousand mentions in the media
- 14 billion figures in StatLine
