Frequently asked questions about the CBS questionnaire

Target research

The Committee has spoken to dozens of adoptees in its investigation of the actual conduct of adoptions from abroad and the role of the Dutch government. In addition to questions about abuses, it has also been discussed how adoptees fare, how they have experienced their adoption, the extent to which they are looking for their origin and what problems they are experiencing. The Committee has also asked what would help them move forward.

The Committee cannot (unfortunately) speak directly to all adoptees when it considers it essential to give the fullest possible picture. That is why the Committee has asked CBS to carry out additional investigations. With this investigation, the Committee wants to examine the extent to which the image that has emerged from the discussions also lives with other adoptees. It helps the Committee to draw responsible conclusions and make recommendations to the Minister.

Finding truth is an important objective of the investigation. Moreover, the Committee would like to contribute to a solution for those who are experiencing problems due to the way in which their adoption has gone in the past. When many people fill out the questionnaire, a representative picture is created.

The CBS questionnaire is not intended to understand the actual role and responsibility of the government in intercountry adoption in the past. For the answer to this question, the Committee uses  interviews, document research and media analysis, among other things.

CBS reports on results at the grouplevel. Statistic information, reactions and data of individuals are not identifiable or traceable in this report.  The main results  from the CBS report are incorporated into the Committee’s reporting. The total CBS report is included in the report and is published on the CBS site.

Privacy

CBS used the Basic Registration of Persons (BRP) as tracked by municipalities in the sample.  CBS receives information from the BRP solely for the purpose of carrying out its legal task: ‘carrying out statistical research for the purposes of practice, policy and science and making public the statistics compiled on the basis of such research’.

The website https://www.rijksoverheid.nl/onderwerpen/privacy-en-persoonsgegevens/vraag-en-antwoord/wie-krijgen-mijn-persoonsgegevens-uit-brp lists organisations authorized to obtain information from the BRP, what data it is about and what they may be used for. CBS is included among Other organizations. All authorisation decisions are also listed there, so that it is also visible for what purpose or goals an organization obtains data.

It  is  not  known whether  anyone has been adopted- thereis also  no  adoption register. In order to be able to draw a sample of intercountry adopted persons in the Netherlands, CBS has made an approach based on well-known data. For this purpose, CBS has used the Basic Registration of Persons (BRP) as tracked by municipalities. As a first step, CBS has created a list of native countries known to be the ones that most intercountry adopted people born from 1970 to 1998 come from. Subsequently, it was checked whether the country of birth of the legal parents is the same as that of the person concerned. If this is not the case and at least one of the legal parents was born in the Netherlands, the person is included in the sample framework. A (large) chance-based sample was subsequently drawn from this group of people. At the beginning of the questionnaire, the question is asked whether one has been adopted or not, so that only adopted persons receive the questions about adoption. In addition to this ‘derivative’ sample, a (random) sample of persons from the BRP with years of birth from the same period was drawn, who – when they indicate at the beginning of the questionnaire that they were not adopted – are presented with the general, non-adoption-related questions.

No. See also the answer  above.

CBS uses the address data only to enroll people. However, once the answers are received, they are immediately completely stripped of this personal data. So even the researchers who analyze this data within CBS do not have access to the address data. In addition, CBS never releases statistical data that can be traced back to individuals. CBS only publishes data at group level. It is therefore impossible that the identity of someone who participated in the investigation will become known in any way. This obligation to confidentiality of personal data is strictly regulated in the Law of the Central Bureau of Statistics.

CBS handles your personal data very carefully and meets the highest data protection requirements. Very strict measures have also been taken against theft, loss or misuse of personal data. CBS shall only publish statistical information if the reactions and data of individuals are not identifiable or traceable. And everything CBS publishes is made public. So everyone in the Netherlands has access to the same information. CBS never provides recognizable or traceable data to third parties. Not even to other government agencies. This also means, for example, that the Committee does not receive individual data from CBS.

Participation research

Unfortunately that’s not possible. Only people from the randomly drawn sample can participate in the study. This is important for the representativeness of the research.

It is important in this study that both adopted persons and non-adopted persons participate, so that it is possible to compare the situations of both groups. People who have been approached for this study represent many other inhabitants in the Netherlands. In order to get a reliable picture, it is therefore important that as many people as possible participate.

For this survey, CBS asks both adopted and non-adopted adults to complete a questionnaire about living situation, well-being and views on adoption. It is important to know what they think and what they are experiencing and whether they differ. CBS does this on behalf of the independent Committee Investigating Intercountry Adoption in the past (the Joustra Committee).
You represent many other residents in the Netherlands. It is therefore important that you participate in this study. Only if enough people participate do we get a good picture.

Other

When sending, you send the information in encrypted form to CBS. At CBS the data ends up in a secure environment where the files are stripped of directly identifying personal data. This means that research files do not contain data such as names, addresses or Citizen Service Numbers. As an independent statistics agency, CBS analyzes and reports on this.

CBS only publishes statistical information if the reactions and data of individuals are not recognizable or traceable. Everything that CBS reports to the Committee is made public. Everyone in the Netherlands therefore has access to the same information. CBS never supplies recognizable or traceable data to third parties. This means that the Committee does not receive individual data from CBS. More information about how CBS handles personal data can be found at https://www.cbs.nl/nl-nl/over-ons/organisation/privacy.

The Committee processes the information from the CBS report in its own report to the minister. This report is also public.

Unfortunately, this is only possible in company investigations. Companies are legally required to cooperate with CBS investigations. The printing function is there so that the companies can store the data in their records to use it later for further operations. The questionnaires for the company studies are built in a different way than personal surveys. As a result, it is not possible to use the printing function in personal surveys. Such a printing function is not available in any other persons research.
