Access to CBS microdata

In November 2015 the University of Twente and Statistics Netherlands (CBS) signed a partnership agreement. Thanks to this agreement our researchers can now take advantage of the extensive data collections of CBS. The CBS data hold all data collected by Dutch government and a lot of public bodies.

There are two ways to make use the CBS data:

-

CBS StatLine database: more than 3400 freely and directly available statistical datasets, consisting mainly of tables and figures. These data are based on observations and can be used to gain insight into phenomena in Dutch society or to formulate, monitor and evaluate policies.

-

CBS Microdata: anonymized data at the level of private individuals or companies. These data are more detailed and more specific than the StatLine data, and can even be combined with your own datasets. The microdata can be used by researchers under strict conditions via a remote access terminal, available for UT researchers in the Ravelijn. More specific information on accessing Microdata can be found in the CBS service catalogue and the Microdata guidelines. An overview of available Microdata can be found in the Microdata catalogue (currently in Dutch only). To get permission to use the CBS Microdata, follow the steps described below.

Procedures

All microdata will remain in the secure CBS environment. Researchers only have access to the data needed for their own research. Researchers use the secure environment made available to them, in which they can store draft versions, syntaxes and output. If they wish to export (draft) results from the secured environment, the export will be carried out by CBS. CBS will verify that the results do not contain any identifiable data.

Please note:

-

The entire process (from handing in your first research proposal to actually accessing the data you required) may take a few weeks, depending on the exact request.

-

There are costs involved in using CBS Microdata (see “tariff structure”, service catalogue p.9-10). To promote the use of CBS Microdata, IGS Datalab offers to fund the first 10 research projects.

A maximum amount of €3.000,- per project applies, to be claimed at IGS Datalab within one month after receiving the invoice from CBS.

Request permission to use CBS Microdata:

1.

Hand in your research proposal (describing research design and questions) at IGS Datalab

2.

Plan an intake interview with Statistics Netherlands (via) to discuss:

-

the target and feasibility of the research project

-

which Microdata is required and which queries need to be run

-

what costs are involved

3.

Formulate the research project together with CBS, specifying the required datasets and costs

4.

Contact IGS Datalab to come to an agreement about the costs

5.

Get your fingerprints taken at CBS (The Hague or Heerlen) to get authorized to use the remote access terminal

Using the CBS remote access terminal:

When authorization is granted, UT researchers can use the CBS remote access terminal. This terminal is located at the secure Datalab room (room left to RA5432) in the Ravelijn. To use the terminal, follow the steps below:

1.

Check the availability of the Datalab room via the Outlook Calendar:

Ravelijn-Room-5432-IGS Datalab

2.

Reserve the room at your convenience by contacting the IGS secretary (Marcia Clifford, T: 053 489 3423, room RA1438)

On the reserved date and time:

3.

Sign the list at the IGS secretary and get the key to the room

4.

Read the house rules before starting your work

5.

Start the CBS terminal and connect to the CBS website using the fingerprint scanner

6.

Start/continue your research using CBS databases

Current projects

The IGS Datalab currently facilitates and supervises researchers of the OMD (Research Methodology, Measurement Methods and Data Analysis) and OWK (Educational Science) departments.

-

Stéphanie van den Berg (OMD) is researching the interaction between biological make-up and environmental influences on school performance. CBS has a rich dataset that she can easily analyze with the aid of the terminal, which saves lots of travelling to and from The Hague.

-

Hans Luyten and Ilona Veer (both OWK) are using the CBS terminal for their ‘Start Groups’ research. They are matching respondents from an experimental group and a control group based on background data (education, country of birth, etc.) obtained via CBS.

-

John Pritchard (CTW) is using the CBS terminal as part of the ASTRID project. He explores the job accessibility in the Netherlands as a way to study whether there are underprivileged clusters of individuals.
