This metadata information is provided by the Danish Immigration Service to ensure compliance with the requirements of Article 4.4 (Dublin statistics) of Regulation (EC) 862/2007 on Migration and International Protection as amended by the Regulation (EU) 2020/851.

As required by Article 9 of the Regulation (EC) 862/2007, Member States must report to Eurostat on the data sources used, the reasons for the selection of these sources and the effects of the selected data on the quality of the statistics. Member States shall provide Eurostat with all the information necessary to evaluate the quality, comparability and completeness of the statistical information.

The reference document used for assessing the compliance of the concepts and definitions in this metadata file is the document Dublin statistics - Eurostat Technical guidelines to Dublin statistics (see Annex).

All statistics 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.
There are two separate institutions from where data is collected under article 4.4 - the Danish Immigration Service and Home Return Agency. Both are using the same electronic case handling system (ECDH).

The processing and compilation of Dublin statistics are solely based on administrative records from ECDH as per August 1, 2020. Before August 1, 2020 statistics about incoming and outgoing transfers were collected from The Danish National police.
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.

Migration and international protection – Dublin statistics

See below.

The text of article 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.

Third country nationals concerned by each request, decision and transfer under Dublin Regulation III.

All statistics 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.

There are two separate institutions from where data is collected under article 4.4 - the Danish Immigration Service and Home Return Agency. Both are using the same electronic case handling system (ECDH).

The processing and compilation of the residence permits 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. Lists with erroneous registrations are produced and sent to the relevant authorities for further action. Despite the care taken in registering, updating and compiling the statistics, there are some challenging/known issues, such as length of validity, the registration of which in the systems is not compulsory. However, in general the data is of “Good” quality and reliable.

• Good quality (extensive quality) - all quality requirements are met according to the standard quality criteria and in line with the Technical Guidelines for the data collection of Dublin statistics (Annex).
• Sufficient quality (acceptable quality) - minimum quality requirements are met: minor issues exist which need to be improved.
• Poor quality (inadequate quality) - the data do not meet the minimum quality requirements: important/many issues exist which affect the quality of the data and which need to be solved.

 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 : The figures from Eurostat are not published at the national level. However, the Danish Immigration Service is aware that both journalists and politicians use numbers from   Eurostat's databases in their daily work. 

 Unmet user needs (on statistics) and reasons why these needs cannot be satisfied (at national and international level) : There has not been any surveys regarding user needs or   satisfaction at the national level.

However, in general the data is of “Good” quality and reliable.

Accuracy is the closeness of the data to the exact or true values that the statistics were intended to measure. Reliability is the closeness of the initial provided value to the subsequent (revised) value.

Assessment of the accuracy of the national Dublin statistics, at dataset level

• High = 100 % accuracy. The reported statistics measure accurately the target population, as foreseen by Regulation (EC) 862/2007 (as amended by Regulation (EU) 2020/851) and as defined in the Technical Guidelines for Dublin statistics (Annex)
• Good = 95 - 99 % accuracy. The reported statistics do not cover accurately the target population and a small part of the targeted population is missing, or a small part of non-targeted (erroneous) population is included in the reported statistics; the bias/error in the reported statistics is expected to be small
• Low = 80 - 94 % accuracy. The reported statistics do not cover accurately the target population and a large part of the targeted population is missing, or a large part of non-targeted (erroneous) population is included in the reported statistics; the bias/error in the reported statistics is expected to be large
• Very low = less than 80 % accuracy. The reported statistics do not cover accurately the target population and a very large part of the targeted population is missing, or a very large part of non-targeted (erroneous) population is included in the reported statistics; the bias/error in the reported statistics is expected to be very large

Assessment of possible sources of lack of comparability between countries, due to discrepancies from Eurostat concepts, definitions or due to differences in methods.

See below.

The totals are comparable throughout the period 2008 until the reference year.

The information about legal provision is comparable from the year 2014 until the reference year.

Asylum statistics collected under Article 4 of the Regulation (EC) 862/2007 are based on persons, while Dublin statistics may refer to requests in a few cases.

Not applicable.

Persons reported under 'Decisions on outgoing requests' will not necessarily be reported under outgoing transfers in the same year.
Persons reported under 'Decisions on incoming requests' will not necessarily be reported under incoming transfers in the same year.

The data material undergoes validation on a regular basis. The Danish Immigration Service will send revised data to Eurostat if significant changes occur. 

Denmark will provide Eurostat with reviewed data if changes occur in the reported data.

The main source of revisions is changes in registrations made in the electronic case and document handling system.

When the Danish Immigration Service become aware of significant changes in the registrations in the electronic case handling system (ECDH), revised data will be send to Eurostat with an explanation of the change.

The size of revision gives an idea of the stability of the data while direction is important to understand whether preliminary data tend to overestimate or underestimate the real target population.

Database based on administrative records from ECDH as per August 1st, 2020. Before August 1st, 2020 statistics over incoming and outgoing transfers were collected from The Danish National police.
