Focus on undermining

Municipality of The Hague

Several analyses are carried out in the Focus on Undermining project, see also website www.zichtopondermijning.nl. Work is ongoing to add insights and (new) analyses.

Goal and impact

In the analyses carried out for the Insight into Undermining dashboard, algorithms are regularly applied. Sometimes these are very simple algorithms. After all, where calculation rules are applied, in a strict sense there is already an algorithm. More methodologically complex algorithms are also used, such as a decision tree algorithm in the analysis of young recruitment and subgroup discovery in the group analysis of those involved in suspicious transactions. For the Focus on Undermining dashboard, algorithms are never applied to offer insights or draw conclusions at the level of individual addresses, companies, households or individuals. Individual data are pseudonymised and outcomes are always aggregated. Each analysis on the dashboard is described in detail in the In-depth Information section. There it is explained which analysis methods are applied, whether these are algorithms, which choices were made and which characteristics of addresses, companies, households or individuals were considered. Migration background is used in this dashboard as a characteristic in descriptive statistics of groups of households or persons only if there is sufficient justification for it. It is not used as a characteristic in classification algorithms applied to households or persons.

Considerations

The intended results and insights can only be achieved by working with CBS microdata within the frameworks of the CBS Act. For that reason, the City Deal 'Focus on Undermining' was drafted and signed in 2017 for that purpose. See also: https://zoek.officielebekendmakingen.nl/stcrt-2017-48699.html

Human intervention

Yes, before an analysis outcome is made public, CBS checks the insight for disclosure risk.

Risk management

The CBS needs significant oversight of the entire project and watches out for disclosure risks, among other things.

Legal basis

Processing for scientific and historical research, statistical purposes and archiving in the public interest are always considered compatible with the original collection purpose. But even if they are not further processing, personal data may be processed for these purposes, provided the requirements in the Regulation are met. The Regulation requires that appropriate safeguards be put in place for the protection of the rights and freedoms of data subjects. Those safeguards must, among other things, ensure that technical and organisational measures are in place to process as little personal data as possible, such as pseudonymisation or anonymisation. The processing of personal data for the purpose of the analyses to be carried out will be carried out in compliance with the Personal Data Protection Act (Wbp) and, with effect from 25 May 2018, the General Data Protection Regulation (AVG) and the General Data Protection Regulation Implementation Act as well as, depending on the nature of the personal data to be processed, other relevant legal provisions relating to the protection of personal data, such as the Police Data Act (Wpg), the Judicial and Criminal Records Act (Wjsg) and the Central Statistics Office Act (CBS Act).

Operations

Data

Because multiple algorithms are used, this is difficult to list in one field. CBS uses the BRP, BAG, WOZ, Kadaster.

Technical design

See previous comment, depends on type of analysis
