Q&A Data Storage – New file: Compressed population-scale network

On Tuesday, June 16, 2026, from 14:00 to 15:00, there will be a Q&A session about a new file in the CBS Data Storage. The session starts with a short explanation about offering and using files in the CBS Data Storage. After that, the creators of the file 'Compressed population-scale network' will give a presentation about the file and possibilities for its use. Following this, there will be time for questions.

The Q&A will be in English and is available for a maximum of 50 participants. You can register here. The zoom codes will then be sent to you a few days in advance.

CBS-Microdata Afternoon: Safety and crime (June 4th, 2026)

CBS is organizing the semi-annual CBS Microdata Afternoon on June 4, 2026. The event will take place from 12:00 to 17:30 at CBS in The Hague.

During this afternoon, we bring together researchers to inspire one another and share experiences, with various presentations being given. This edition focuses on Safety and Crime and is primarily intended for (prospective) researchers and project leaders working within the CBS microdata environment.

Participation is free of charge, and lunch is included. Please note that the working language during the afternoon will be Dutch.

New Service: Data Storage

The Data Storage has been introduced within the CBS microdata environment. This service is designed to enable researchers to share large analytical datasets with other researchers. Like catalog files, these are offered as read-only files. An advantage for providers of files is that they no longer incur storage costs in their own project environments. The pilot phase of this service runs until May 2025, and during this period, the storage costs will be covered by ODISSEI. Depending on interest levels, this service may become permanent.

Conditions for placing Files:

  • The file you wish to make available must have been created using only CBS microdata.
  • If you create a file, you are responsible for answering questions related to it.
  • A template for metadata can be found in the CBS microdata environment.
  • Export the script used to generate the files and the metadata describing them and submit both through ODISSEI to the ODISSEI Metadata Portal and Code Repository.

If you wish to place a file, fill out the 'Data Storage Request' form within the CBS microdata environment. This form is in the Utilities folder. Place the completed form on your H-drive in a folder named 'For Data Storage Facility', then email your advisor at Microdata Services that the form has been submitted.

Conditions for Using Files:

  • The requester must justify their request and explain how the file contributes to the research objectives.
  • The requesting party must apply and pay for the CBS microdata topics underlying the file in requested for.

Look in the metadata folder under Utilities within the CBS-microdata environment for more information, as well as in Extern Maatwerk in the OtherData folder for already available files.
