2.1. Data description

1. Introduction

This metadata information is provided by Greece's authorities to ensure compliance with the requirements of Articles 5 and 7 of Regulation 862/2007 on Community Statistics on Migration and International Protection.

As required by Article 9 of the Regulation 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 it with all the information necessary to evaluate the quality, comparability and completeness of the statistical information.

The reference terms for the assessment of quality compliance are provided by Eurostat in the EIL technical guidelines (See section 3.4 Statistical concepts and definitions from the EIL ESMS file).

 

2. General description of the statistical domain at national level

EIL National System (level of development, main changes that affected the system in the last years and further development)

 

The national system of Greece for the generation of the EIL-statistics consists of two different Divisions of the Aliens & Border Protection Branch of Hellenic Police HQs.  For the collection of the EIL statistics Border Protection Division is the responsible authority, which takes over the unification and the upload of the data on behalf of the Hellenic Police/HQs. This system is unchanged since introduction of the EIL-statistics.

 

Legal national framework relevant for EIL statistics

Presidential decree 178/2014

Institutional infrastructure (list of the institutions involved in managing the EIL registers and the institutions involved in the production of the EIL statistics)

Border Protection Division and Migration Management Division of Hellenic Police HQs

 

General procedure for recording Non-EU citizens refused entry at the external borders

All available relevant data registered electronically, prepared for reporting, in specific applications of our national IT system “Police on Line” such as “Mapping of Migrants”. In addition, our division receives, compares and evaluates the collected data, which are reported in a daily base by our regional Services.

 

General procedure for recording Non-EU citizens found to be illegally present

All available relevant data registered electronically, prepared for reporting, in specific applications of our national IT system “Police on Line”, such as “Mapping of Migrants”.

8. Coherence and comparability Top
8.1. Comparability - geographical

1. Provision of data using the Eurostat EIL Technical Guidelines and exceptions applied

Full compliance with EIL technical guidelines.

 2. Details on categories of Non-EU citizens difficult to be classified using the reference definitions from EIL technical guidelines and the categories excluded from these reasons (excluded from the statistics reported)

Full compliance with EIL technical guidelines.

3. Description of records related to "Unknown" country of citizenship category

Full compliance with EIL technical guidelines. 

4. Description of records related to "Unknown" age category

Persons whose current age is not identified. 

5. Description of records related to "Unknown" sex category

Persons whose sex is not identified.

6. Establishing the reported ground in case of “multiple grounds” for the same refusal and the impact on double counting of the person in the same dataset

The methodological procedure of "one ground per refused person", is applied, as laid down in EIL Technical Guidelines (procedure of "higher ground overrules the lower ground for refusal).

There is no impact on double counting.

Land boarder, Sea border and Air border

 8. The definition of “refused Non-EU citizens” applied

The Schengen Borders Code's refusal definition is applies for the Statistics reported to Eurostat

10. The definition of “Non-EU citizens found to be illegally present” applied

The number of third-country nationals who have been detected by authorities while not fulfilling, or no longer fulfilling, the conditions for stay or residence, either when they are detected inland or while trying to exit the territory. 

11. The definition of “Non-EU citizens ordered to leave” applied

The number of third-country nationals subject to an obligation to leave the territory of the Member State as a result of an administrative or judicial decision or act stating or declaring that the stay of the third-country national was illegal according to a return decision/order issued in accordance with national law.

Not applicable

8.2. Comparability - over time

Methodological changes between the present reference year and previous year(s)

There are no changes in the method of collecting and checking the data over the years.

Justification of the important changes in figures reported for the present reference year and previous year(s)

Significant changes in the number of third country nationals 'found to be illegally present' are explained by the unprecedented increase of irregular migration in Greece through the GRC-TUR borders, during the migration crisis in 2015.

1. Links between the statistics on refused Non-EU citizens and the statistics on Non-EU citizens found to be illegally present.

There is no direct link between the statistics on refused Non-EU citizens and the statistics on Non-EU citizens found to be illegally present. The statistics on refused Non-EU citizens refer to the number of third-country nationals refused entry at the external borders. The statistics on Non-EU citizens found to be illegally present refers to the number of third-country nationals who have been detected by Member State authorities while not fulfilling, or no longer fulfilling, the conditions for stay or residence in the Member State during the reference month, whether they were detected inland or while trying to exit the territory. 

2. Links between the statistics on Non-EU citizens found to be illegally present and the statistics on Non-EU citizens with obligation to leave.

There are links between the statistics on Non-EU citizens found to be illegally present and the statistics on Non-EU citizens with obligation to leave. More specifically, our regional Services were issuing return decisions/orders (obligation to leave) to Non-EU citizens found to be illegally present according to our national law. 

EIL-Statistics and Asylum statistics are reported by different authorities.

[Not requested]

8.5. Coherence - National Accounts

[Not requested]

8.6. Coherence - internal

1. Links and differences between the Non-EU citizens with obligation to leave and Non-EU citizens who actually left the territory

There are links between the statistics on Non-EU citizen with obligation to leave and Non-EU citizens who actually left the territory. More specifically, a Non-EU citizen who actually left the territory is a person who actually left the territory while he had already the obligation to leave the territory (a return decision/order issued in accordance with national law). 

2. Links and differences between the Non-EU citizens who actually left the territory and Non-EU citizens who left the territory to a third country

The following classification is used for data availability at Eurostat level:

The term "not applicable" relates to the categories of permits which do not exist in national legislation/administrative procedures and therefore such statistics cannot be issued.

The term "not available" relates to categories of data that exist in the national legal/administrative system but cannot be delivered under EIL data collection for various reasons (e.g. data cannot exist, data exist but are not collected, data are unreliable, etc.).
