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 Dublin statistics contains statistical information based on the Article 4.4 of Regulation (EC) No 862/2007 on Community statistics on migration and international protection.

3.3. Coverage - sector
Migration and asylum – Dublin statistics.
3.4. Statistical concepts and definitions
See table 3.4. in annex ‘Quality report tables Dublin 2024’.
3.5. Statistical unit
The text of Art.4 of the Regulation (EC) 862/2007 on Migration and international protection refers in general to statistics based on the number of persons and not on the number of applications. However, the article describing the 'Dublin' statistics (Art.4.4) refers to statistics based on the number of requests. Commission services recommend that Art.4.4 (more precisely 4.4.a, 4.4.c and 4.4.d) is interpreted as referring to the number of persons concerned by each request, decision and transfer.
3.6. Statistical population
See table 3.6. in annex ‘Quality report tables Dublin 2024’.
3.7. Reference area
Sweden.
3.8. Coverage - Time
See table 3.8. in annex ‘Quality report tables Dublin 2024’.
3.9. Base period

6.1. Institutional Mandate - legal acts and other agreements
The compilation of Dublin statistics is based on Article 4.4 of Regulation (EC) 862/2007 of 11 July 2007 which depicts in details the data provisions Sweden are bound to supply Eurostat with. The Swedish Migration Agency is not a national authority for the national statistics. The Official Statistics Act (2001:99) and the Official Statistics Ordinance (2001:100) are therefore not applicable.
6.2. Institutional Mandate - data sharing
The Swedish Migration Agency collects information about applicants via various sources. Through investigations and conversations with applicants at the agency´s offices in Sweden and at the embassies abroad. Through electronic applications where applicants fill in information themselves. Through coordination with other national authorities' databases (the Swedish Tax Agency, the Swedish Public Employment Service, Statistics Sweden) and through coordination with international databases (DublinNet, Visa Information System).
7.1. Confidentiality - policy
Statistical confidentiality is guaranteed by law, in chapter 24 article 8 in the Public Access to Information and Secrecy Act (OSL 2009:400) and article 7 in the Public Access to Information and Secrecy Ordinance (OSF 2009:641). The provision refers specifically to secrecy for the protection of individuals.
All staff at Swedish Migration Agency (SMA) sign legal confidentiality commitments stating that they have taken note of the relevant confidentiality provisions. Breaches of confidentiality are punishable by The Swedish Penal Code (1962:7800) in chapter 20 article 3.
7.2. Confidentiality - data treatment
There are physical, technological and organisational provisions in place to protect the security and integrity of the data at SMA. Organisational provision are laid out according the legislation outlined in chapter 24 article 8 OSL and article 7 in OSF. Microdata are protected by absolute confidentiality by above mentioned articles in OSL and OSF. Only authorised staff, and as few as possible, are given access to sensitive data concerning statistical activities. For access to the statistics systems, there is an eligibility model based on process, role and eligibility. In order to meet the legal requirements of the Data Protection Regulation (GDPR), the possibility of gaining access to the operational views have been severely limited for the majority of the staff at the agency.

12.1. Relevance - User Needs
The statistics collected under Regulation (EC) 862/2007 are used by a wide range of users at national, European and International level to cover various usersʼ needs.
Users of Dublin statistics : Eurostat, EUAA (European Union Agency for Asylum), Department of Justice, national authorities.
Unmet user needs (on statistics) and reasons why these needs cannot be satisfied (at national and international level) : Data in some cases exhibits various aspects of quality issues from events such as faulty registrations to uncertain unit definition to query limitations.
12.2. Relevance - User Satisfaction
User satisfaction not collected.
12.3. Completeness
See table 12.3. in annex ‘Quality report tables Dublin 2024’.
12.3.1. Data completeness - rate
Not applicable.
13.1. Accuracy - overall
The Swedish Migration Agency has developed a new data warehouse, which generates more quality-assured statistics. The content of the data warehouse is based on information from the central database, but with a logic that makes it easier to handle data for follow-up. In connection with the data warehouse, applications have also been created to make it easier for the business to produce relevant statistics.
13.2. Sampling error
Not applicable.
13.2.1. Sampling error - indicators
Not applicable.
13.3. Non-sampling error
The Swedish Migration Agency (SMA) ensures, through manual and automatic tests, that transformations of the data processing sent to Eurostat are correct. The SMA’s statistics are preliminary because the data is not final. The agency continuously revises previously sent out statistics on changes in data. In SMAs central database, in principle, all statistics relating to information about the applicant and their cases are stored and SMA does not use surveys for data collection.
13.3.1. Coverage error
The Swedish Migration Agency does not use surveys for data collection.
13.3.1.1. Over-coverage - rate
Not applicable.
13.3.1.2. Common units - proportion
Not applicable.
13.3.2. Measurement error
The Swedish Migration Agency bases European statistics on data stored in the agency's central database. The database is based on case and individual information that is registered in the internal processing system. The central database also contains information from other authorities. Since the agency registers information about the applicant and his / her process, from application to decision, the database contains thorough information.
13.3.3. Non response error
Not applicable.
13.3.3.1. Unit non-response - rate
Not applicable.
13.3.3.2. Item non-response - rate
Not applicable.

15.2.1. Length of comparable time series
Not applicable.
15.3. Coherence - cross domain
Incoherence between subannual and annual statistical outputs is mainly due to post registrations.
The data history is not “locked”, which means that improvement work is carried out continuously, even on historical data. If definitions change over time, the definitions of historical data also change so that it becomes comparable over time. Statistical data from different data sources and different time periods are compared and adjusted.
15.3.1. Coherence - sub annual and annual statistics
Variables pertaining to the individual refer to the most recent registration at the date of data extraction, reporting of the same month can thus vary depending on the date of data extraction.
