6.1. Institutional Mandate - legal acts and other agreements | |||
Enforcement of immigration legislation data (EIL statistics) contain statistical information based on Article 5 and 7 of the Regulation (EC) No 862/2007 as amended by the Regulation (EU) 2020/851 The Ministry of Justice and Security, including the migration agencies and the Police, and the Royal Marechaussee acting under the authority of the Ministry of Justice and Security, are responsible for the registrations in the field of immigration legislation; the data is collected by the Ministry of Justice and Security (Aliens Act 2000).
The "Wet op het Centraal bureau voor de statistiek, van 2 maart 2022" (the dutch Law on Statistics Netherlands, March 2, 2022) states in article 4 that CBS is responsible for the production of the EU statistics.
This comprises all (mandatory and voluntary) statistics mentioned in the several EU Regulations and Directives.
A convenant has been signed between the Ministry of Justice and Security and CBS (signed August 30, 2023) regarding the provision of data from the Ministry to CBS for the purpose of statistics, e.g. specifying and regulating all data transfers between the Ministry (and its agencies and institutions) and CBS.
|
|||
6.2. Institutional Mandate - data sharing | |||
Data sharing is conform the convenant between the Ministry of Justice and Security and CBS (of August 30, 2023) regarding the provision of data from the Ministry to CBS for the purpose of statistics. The Ministry of Justice and Security is responsible for data collection in the field of immigration legislation. They compile all EIL statistics, and send the (aggregated) tables to CBS. CBS has set up a safe and automated data processing system to receive the tables from the data supplier, to process the data, and send the statistics via Edamis to Eurostat. This system includes the "database EU Asylum and managed Migration", plus a monitoring system, and several automated procedures for receiving and sending data. All procedures are in accordance with the CBS standards in the field of data collection and processing. |
|
|||
7.1. Confidentiality - policy | |||
The General Data Protection Regulation applies in The Netherlands, and therefore to CBS and the Ministry of Justice and Security. Moreover, the "Wet op het Centraal bureau voor de statistiek, van 2 maart 2022" (the dutch Law on Statistics Netherlands, March 2, 2022) states in article 37 that CBS will not disclose any data that might identify a person, household or economic entity, either directly or indirectly. [wetten.nl - Regeling - Wet op het Centraal bureau voor de statistiek - BWBR0015926 (overheid.nl) ] |
|||
7.2. Confidentiality - data treatment | |||
In general, CBS defines a confidential cell as a cell where the number is lower than 7. Usually this cell is suppressed, however, depending on the statistic, also controlled rounding can be used, for example to the nearest fivefold or tenfold. CBS checks in general for residual disclosure, with methods depending on the statistic. In the publications in Statline based on the EIL data, the data is treated in the same manner, data are rounded to the nearest fivefold to prevent disclosure. As Eurostat itself has confidentiality rules for publications (rounding to nearest fivefold for the EIL data), and because of the secured process of sending data via Edamis to Eurostat, there is no rounding in the supplied tables. |
|
|||
8.1. Release calendar | |||
Besides by Eurostat, EIL data is also published by CBS in four annual Statline tables: StatLine - Datasets via thema (cbs.nl) In each of these tables there is an Explanation, stating when the data of the new period will be published. These tables and Explanation are publicly accessible. |
|||
8.2. Release calendar access | |||
The Statline tables concerning the EIL data can be reached via: StatLine - Datasets via thema (cbs.nl) The moment of publication of the new data can be found under "tabelinformatie - tabeltoelichting" (Explanation). |
|||
8.3. Release policy - user access | |||
The general release policy of CBS is to publish all regular statistics via Statline and Open Data: StatLine (cbs.nl) This is accessible to the general public via the website of CBS. The policy for publishing incidental statistics is via incidental publications on the webpage at www.CBS.nl: Overzicht aanvullend statistisch onderzoek per jaar | CBS. This is also accessible to the general public. In addition, statistics may be presented by dashboards, or other visuals. Moreover, any newly published statistic may be accompanied by a written 'news item' which gives some highlights of the data or a longer analysis. Every part of a publication is available on www.CBS.nl. By these methods of publication, CBS provides for the dissemination of statistical data to all users at the same time. The publicatieplanning on the CBS-website gives an overview of the dates and moments that statistics are made publicly available through an 'news item' . Other statistics (without news item) are made publicly available from 0:00 h (at night) in our databank StatLine. CBS publishes its release policy on its website : Publicatiebeleid | CBS. This policy provides for the dissemination of statistical data to all users at the same time. CBS may send new publications under embargo, in advance of the release of the data, to government organisations and agencies, and to the press. For the press, the maximum embargo period is 24 hours before publication. For the governmental organisations, the maximum embargo period is from 12:00 h in the afternoon on the working day before publication.

CBS disseminates the statistics related to the EIL tables on an annual basis. |
|
|||
10.1. Dissemination format - News release | |||
Each year, based on the EIL data, 4 tables are published in Statline : StatLine - Datasets via thema (cbs.nl). These were last updated on September 1, 2023, with data on reference year 2022, and will be updated in June 2024 by adding the data regarding reference year 2023. |
|||
10.2. Dissemination format - Publications | |||
The publication of statistics based on EIL data has been, for the last couple of years, mostly in the form of Statline tables : StatLine - Datasets via thema (cbs.nl). CBS sometimes issues a publication in the form of an 'news item' , for example in 2021 on the topic of persons refused at the border StatLine - Datasets via thema (cbs.nl). |
|||
10.3. Dissemination format - online database | |||
Based on the EIL data, 4 tables are published in Statline : StatLine - Datasets via thema (cbs.nl). 1) Third Country Nationals refused at the border: StatLine - Derdelanders, geweigerd aan de grens; nationaliteit (cbs.nl) 2) Third Country Nationals who have actually left: StatLine - Derdelanders; aantoonbaar vertrek (cbs.nl) 3) Third Country Nationals with illegal presence: StatLine - Derdelanders; illegale aanwezigheid vastgesteld, nationaliteit (cbs.nl) 4) Third Country Nationals ordered to leave: StatLine - Derdelanders; verplichting tot vertrek (cbs.nl)

|||
18.2. Frequency of data collection | |||
All source data are collected and processed continuously by the Ministry of Justice. In order to submit the data to Eurostat, compilations of the data are made on a quarterly or annual base. |
|||
18.3. Data collection | |||
General procedure for recording Non-EU citizens refused entry at the external borders: After detection at a Border Crossing Point (BCP) of a TCN with insufficient papers for entering the Schengen Borders a registration is made in VBS, the registration system of the RNM and the SPP.
General procedure for recording Non-EU citizens found to be illegally present: After detection of a illegally staying TCN during mobile security monitoring by the RNM a registration is made in VBS. When National Police detects an illegally staying TCN a registration is made in PSH-V.
General procedure for recording Non-EU citizens ordered to leave:
General procedure for recording Non-EU citizens returned following an order to leave: Return is registered by multiple partners, RNM, Police and R&DS. Each organization uses its own primary registration system. Each organization sends its data on to the Ministry of Justice and Security where the data is collected and processed in KMI+. |
|||
18.4. Data validation | |||
The following checks are performed in the systems: When there are more than one record for a person in the reference period (with identical foreignernumbers), these are deduplicated in KMI+. Plausibility checks are performed by comparing the data with previous periods. Deviating increases or decreases in numbers are investigated and explanations are sought, in order to ensure it is not caused by an omission or error in the data or query. A check of consistency between Y2 and Y3 does not seem very useful in the Dutch context as most orders to leave/return decisions are issued when a application is refused or a permit is withdrawn. A check of consistency between "TCNs subjects to an obligation to leave" and "TCNs who actually left the territory" seems only possible if this can be done based on a cohort of persons obligated to leave taking into consideration the time that can elapse between the moment that the obligation started and return and all other possible outcomes (such as abscondment and issuance of a permit). |
|||
18.5. Data compilation | |||
Table Y 6.1: The country of destination is sometimes not known although the type of return is assisted voluntary or forced return. In those cases, the destination country is assumed to be the country of citizenship. This annually applies to 10-20 returns. In case of unassisted voluntary return, the country of destination is reported as unknown in the majority of cases.This is due to the process at the border, where country of destination is not registered. Efforts are made by the RNM and the Ministry to improve this process and decrease the number of unknown countries of destination. |
