Reference metadata describe statistical concepts and methodologies used for the collection and generation of data. They provide information on data quality and, since they are strongly content-oriented, assist users in interpreting the data. Reference metadata, unlike structural metadata, can be decoupled from the data.
Data collection on the residence permits (RESPER) statistics contains statistical information based on the principles stated in the Union legislation on migration Regulation (EC) No 862/2007 as amended by the Regulation (EU) 2020/851 and the Commission Regulation (EU) No 216/2010 implementing the categories of reasons for residence permits.

Residence permits issued on the occasion of changing the immigration status or reason to stay,
Residence permits valid at the end of the year,
Long-term residence permits valid at the end of the year,
Long-term permits issued during the year.

The law on Statistics Denmark, "Bekendtgørelse af lov om Danmarks Statistik", LBK nr 610 of 30 May 2018, is the main national legal act regarding official national and international statistics.
All statistics on asylum are collected and processed by the statistical unit at the Danish Immigration Service. The unit provides statistics on behalf of all migration authorities in Denmark including the Ministry of Immigration and Integration.
6.2. Institutional Mandate - data sharing
Not applicable.
7.1. Confidentiality - policy
Regulation (EC) No 223/2009 on European statistics (recital 24 and Article 20(4)), stipulates the need to establish common principles and guidelines ensuring the confidentiality of data used for the production of European statistics and the access to those confidential data with due account for technical developments and the requirements of users in a democratic society.

7.2. Confidentiality - data treatment
The Danish Immigration Service treats personal information in line with the General Data Protection Regulation, supplemented by the national "Databeskyttelsesloven" LOV 289 of 08 March 2024. More information on processing of personal data can be found here: New to Denmark (nyidanmark.dk)
8.1. Release calendar
Statistical information is published in accordance with an approved release calendar.
Apart from providing data on residence permits to Eurostat, the Danish Immigration Service provides weekly, monthly and yearly publications in Danish on its website: Tal og statistik (us.dk). A release calendar can be found under each publication.

Ad-hoc press releases are usually published by the Ministry of Immigration and Integration.
10.2. Dissemination format - Publications
Weekly, monthly and yearly publications are released on the website of the Danish Immigration Service: Tal og statistik (us.dk) (in Danish)
Data checks and data validation are performed regularly. The Statistical Unit is in constant contact with the specialist offices for consultation on suspicious/unusual registrations (outliers or obvious mistakes such as a negative age) and feedback on the plausibility of the numbers. Case managers have access to statistics with a delay of maximum one day and can thereby follow the development of the numbers almost in real time. Finally, there are more extensive checks performed at the end of a year and in connection with regular publications, such as the delivery of data to Eurostat.
11.2. Quality management - assessment
Residence permits statistics are based on administrative sources which allows a good quality of the data.
12.1. Relevance - User Needs
Users of Eurostat residence permits statistics are:
various policy DGs in the European Commission, like DG Migration and Home Affairs for designing, funding and implementing migration related policies in the EU,
European Parliament,
national authorities (Ministries of Interior, Ministries of Justice, immigration agencies) who use migration data to monitor or project the development of their national asylum procedures,
European Migration Network (EMN) which uses the migration data as a basis for its annual EU and national level statistical and analytical reports,
researchers and students conducting analysis and research in the field of residence permits,
journalists and international organisations in the area of migration.
12.2. Relevance - User Satisfaction
The Danish Immigration Service does not conduct user satisfaction surveys per se. Instead, the user satisfaction is monitored on a constant way through informal and formal contacts and communications with users and through requests and comments received by users.
12.3. Completeness

18.3. Data collection
By default, the Danish Immigration Service records administrative data on all residence permits.
The collected data of the original electronic file system is transferred to the data warehouse overnight in the form of statistic-relevant data records. Each data record is clearly identifiable via the person id already assigned in advance.
The data on valid residence permits are retrieved once a year through Statistics Denmark.
18.4. Data validation
The statistics are carried out annually as a complete survey on the basis of an electronic file system. Consequently, sample-related errors are excluded. The input data is continuously validated during the process and subjected to a plausibility check. Errors due to incorrect information in the input data cannot be ruled out. As a result, the data on residence permits are generally of high significance, quality and validity.
18.5. Data compilation
The processing and compilation of the residence permit statistics are solely based on administrative records – from ECDH. As a main rule, the compilation of statistics is based on figures directly retrieved from the ECDH system by using a Business Intelligence (BI) solution– no cell rounding of the data is applied. The data material undergoes validation on a regular basis.
