3.1. Data description | ||||||||||||||||||||||||||||||
Eurostat's annual collections of statistics on international migration flows are structured as follows:
The aim is to collect annual mandatory and voluntary data from the national statistical institutes. Mandatory data are those defined by the legislation listed under ‘6.1. Institutional mandate — legal acts and other agreements’. The quality of the demographic data collected on a voluntary basis depends on the availability and quality of information provided by the national statistical institutes. For more information on mandatory/voluntary data collection, see 6.1. Institutional mandate — legal acts and other agreements. The following data on migrants are collected under unified demographic data collection:
a. Country of citizenship; b. Country of birth; c. Country of previous residence.
a. Country of citizenship; b. Country of birth; c. Country of next residence. |
||||||||||||||||||||||||||||||
3.2. Classification system | ||||||||||||||||||||||||||||||
For GEO (reporting country), CITIZEN (citizenship), C_BIRTH (country of birth) and PARTNER (country of previous/next residence) classifications, the two-letter ISO (International Organisation for Standardisation) 3166 alpha-2 code is used. However, Greece and the United Kingdom are exceptions to this, for which the abbreviations EL and UK are used. |

3.4. Statistical concepts and definitions | ||||||||||||||||||||||||||||||
Immigration: the action by which a person establishes his or her usual residence in the territory of a Member State for a period that is, or is expected to be, of at least 12 months, having previously been usually resident in another Member State or a third country. Emigration: the action by which a person, having previously been usually resident in the territory of a Member State, ceases to have his or her usual residence in that Member State for a period that is, or is expected to be, of at least 12 months. Usual residence: the place where a person normally spends the daily period of rest, regardless of temporary absences for purposes of recreation, holidays, visits to friends and relatives, business, medical treatment or religious pilgrimage or, in default, the place of legal or registered residence. The following persons alone are considered to be usual residents of the geographical area:
Immigrant: a person undertaking an immigration. Emigrant: a person undertaking an emigration. Citizenship: the particular legal bond between an individual and his/her State, acquired by birth or naturalization, whether by declaration, choice, marriage or other means according to national legislation. Foreigner: recipient of a citizenship different to the citizenship of the country that person is living in. A foreigner is either a citizen of another Member State or a citizen of a non-EU country. Non-national: recipient of citizenship other than the citizenship of the country that person is living in, or a stateless person. A non-national is either a citizen of another Member State or a citizen of a non-EU country, or a stateless. Stateless: A stateless person is not considered as a national by any State under the operation of its law, as set out in article 1 of the 1954 Convention relating to the status of stateless persons. Recognised non-citizens: Persons who are not citizens of the reporting country, nor of any other country, but who have established links to the reporting country, which include some but not all of the rights and obligations of full citizenship. This category consists mainly of former Soviet citizens living in the Baltic States who have not applied for the citizenship of their current country of usual residence. Country of birth: the country of residence (in its current borders, if the information is available) of the mother at the time of the birth or, in default, the country (in its current borders, if the information is available) in which the birth took place. Countries by inclusion/exclusion of live births occurred outside the reporting country in Immigration flow for 2013-2020
* If registered in the reporting country. ** CZ: If live birth is registered in the reporting country later than February T+1, and within 3 years after birth. *** NL: If the child enters the country later than 8 days after his birth. Age reached: age at the end of the year. Age completed: age on the last birthday. Historical age definition of migration statistics under Article 3 of Regulation (EC) 862/2007
Notes:
Albania, Serbia, Turkey, Andorra, Armenia, Azerbaijan, Republic of Bosnia and Herzegovina, Belarus, Georgia, Monaco, Republic of Moldova, Russian Federation, San Marino, Ukraine and Kosovo (under UNSCR 1244) are not included in the analysis because their data are not disseminated online from 2008 onwards due to definitional problems or lack of data availability. Level of development: the relative degree of development of a country as defined by statistical measures of three basis dimensions - health, education and standard of living. The list of countries and citizenships to be included in each groups by level of development is given in Annexes. Refugee: person granted refugee status (as defined in Art.2(e) of Directive 2011/95/EC within the meaning of Art.1 of the Geneva Convention relating to the Status of Refugees of 28 July 1951, as amended by the New York Protocol of 31 January 1967) or person granted subsidiary protection (as defined in Art.2(g) of Directive 2011/95/EC and person covered by a decision granting authorisation to stay for humanitarian reasons under national law concerning international protection. Asylum seeker: First-time asylum applications are country-specific and imply no time limit. Therefore, an asylum seeker can apply for first time in a given country and afterward again as first-time applicant in any other country. If an asylum seeker lodge again an application in the same country after any period of time, (s)he is not considered again a first-time applicant. Countries by inclusion/exclusion of asylum seekers and refugees in the data on population reported to Eurostat in the framework of the Unified Demographic data collection Reference Year 2015-2022
(1) Asylum seekers and refugees without residence permit are not included. Countries by inclusion/exclusion of asylum seekers and refugees in the data on migration reported to Eurostat in the framework of the Unified Demographic data collection Reference Year 2015-2022

15.1. Comparability - geographical | |||||||||||||||||||||||||||||||||||||||
The recommended definition of population, in line with Regulation (EC) No 862/2007, is the ‘usually resident population’, meaning all the people usually resident in a Member State on the reference date. On the basis of this definition, the following people alone are considered usual residents of the geographical area in question: those who have lived in their place of usual residence continuously for at least 12 months before the reference date or those who arrived in their place of usual residence during the 12 months before the reference date with the intention of staying there for at least 1 year. If the circumstances described above cannot be established, ‘usual residence’ can be taken to mean the place of legal or registered residence. According to Regulation (EC) No 862/2007, migrants should be defined the same way as population. For example, if population is defined in terms of usual residence, then the number of immigrants should be the number of those who establish their usual residence in the territory of a Member State for a period that is, or is expected to be, of at least 12 months, having previously been usually resident in another Member State or a non-EU country. The metadata provided by the countries in question confirm that migration statistics are calculated according to the harmonised definition given above. Countries by time criteria used for the definition of migration and typology of flow for 2013-2022:

|||||||||||||||||||||||||||||||||||||||
15.2. Comparability - over time | |||||||||||||||||||||||||||||||||||||||
Breaks in data series could compromise comparability over time. The breaks in migration series due to methodological changes, data processing changes or revisions in migration counts reported by the countries in question are documented in Eurostat’s database with the flag b (break in series). The reason the migration flows data available between reference years 2008 and 2009 is flagged as a break in the series is a change in methods of production, described as a first shift from the national definition of migration to the 12-month definition. The migration data for 2011 and thereafter take into account the results of the population census held in 2011. By the end of 2013 some of the countries had revised the time series for migration between the previous census and 2011, taking into account Eurostat’s recommendation to provide more information about data revision per country, (see also 17. Data revision). Following Eurostat’s recommendations to ensure consistency of statistics over time, several Member States (Bulgaria, Germany, Ireland, Greece, Spain, France, Croatia, Italy, Cyprus, Lithuania, Hungary, Malta, Poland, Portugal, Norway) have revised or are in process of revising their population or migration time series between the reference years of the population and housing censuses held in 2011 and 2021. Improvements in and changes to administrative systems and statistical methodology may also cause breaks in the time series. There is more information on methodology by country in the annex. |

15.3. Coherence - cross domain | |||||||||||||||||||||||||||||||||||||||
First residence permits statistics issued to third country nationals are often considered by the general public as equivalent to long term international immigration of third country nationals' statistics. However, the two data sources are not fully coherent. Main reasons are differences in concepts and methods. In particular, there are two main types of effects from those differences: 1. A residence permit is also considered as a first residence permit if it is a renewal permit issued for the same reason but with a time gap of at least 6 months between expiry of the old and the start of the validity of the new permit, irrespective of the year of issuance. Therefore, first residence permits statistics include cases who were already present in the country and have been issued a renewed residence permit after an expiry of their previous permit. In addition, a person whose initial residence permit may be valid for less than 12 months, is however included in the immigration flow, if their residence permits (or consecutive residence permits) are extended to a total of 12 months during the year. 2. Data on migratory events should be provided with reference to the time of occurrence, unlike data on residence permits where the date of reference is that of the administrative act. Most likely, there is a time gap between the two events (factual migration and issuance of the residence permit), and the closer the factual migration is to the end of the year, the higher the probability that the two events will be reported in two different reference years. This is also the case in periods where there are high inflows which put the regular administrative system under unusual burden. For conceptual variations, please refer to 3.4."Statistical Concepts and definitions" in "International migration and Residence Permit statistics metadata". For details regarding methods and errors, please see in 18 "Statistical processing" and in 13. "Accuracy" in "International migration and Residence Permit statistics metadata". There is more information on the difference in the annexes. |

15.4. Coherence - internal | |||||||||||||||||||||||||||||||||||||||
The datasets [migr_imm8] and [migr_emi2] are based on the unified demographic data collection (UNIDEMO). From 2008 onwards the annual migration data fall under the requirements of Regulation (EC) No 862/2007 of the European Parliament and of the Council on Community statistics on migration and international protection. This means that these statistics are collected by countries according to harmonised definitions listed in 3.4. Statistical concepts and definitions. For the annual demographic balance data collection (DEMOBAL), Eurostat produces net migration figures by taking the difference between total population change and natural change. This is referred to as net migration plus statistical adjustment. In other words: Net migration plus statistical adjustments (T-1) = population change (T-1) — natural change (T-1), where: Population change (T-1) = population as of January T — population as of 1 January (T-1) Natural change (T-1) = live births (T-1) — deaths (T-1) The statistics on ‘net migration plus statistical adjustment’ might therefore be affected by statistical inaccuracies or by methodological differences in the two components of this equation. From one country to another ‘net migration plus statistical adjustment’ may cover, besides the difference between inward and outward migration, other changes observed in the population figures between 1 January in 2 consecutive years that cannot be attributed to births, deaths, immigration or emigration. This explains the difference between the calculation of net migration by the user, using harmonised definitions, and ‘Net migration plus statistical adjustment’ presented in the dataset [demo_gind] using the national definition and as the difference between the population and natural change. See the reference metadata Population change — Demographic balance and crude rates at national level. |

17.1. Data revision - policy | |||
The policy of Eurostat is to update the information it provides as soon as data are received and at any time during the year. To further specify the general Eurostat revision policy, the following revision policy has been established for demographic and migration statistics (as available in Commission Implementing Regulation (EU) No 205/2014, art 5): 1. Member States shall inform the Eurostat of any planned revision of the data already supplied no later than one week before the release of the revised data in the Member State concerned. 2. Member States shall provide any revised data to the Eurostat no later than one week after the release of these data. 3. Member States shall ensure that any revised data provided to the Eurostat is consistent with the whole set of data already provided. For more information please see also in the Eurostat dedicated sub-section on international migration, citizenship. The policy of Eurostat is to make updates as soon as data is received and at any time during the year. |
|||
17.2. Data revision - practice | |||
Migration statistics are revised on a continuous base according to the most recent data released and transmitted to Eurostat by the National Statistical Institutes. The geographical aggregates and the indicators are accordingly revised. The status of the data is indicated using flags (p = provisional data; e = estimated; b = break in time series). The revision practice effectively corresponds to the revision policy of the domain listed under sub‑concept 17.1 (data revision – policy). All reported errors (once validated) result in corrections of the disseminated data. Reported errors are corrected in the disseminated data as soon as the correct data have been validated. Data may be published even if they are missing for certain countries or flagged as provisional or estimated for certain countries. They are replaced with final data once transmitted and validated. European aggregates and indicators are updated for consistency with new country data. Whenever new data are provided and validated, the already disseminated data are updated and European aggregates and indicators are accordingly revised. Data are usually revised for the last period. Countries however may choose the length of the revisions depending on the need. The impact of major revisions is analysed in working documents produced for experts' meetings held with representatives of National Statistical Institutes. Major revisions are pre-announced and documented in the metadata files available in dissemination. |

18.1. Source data | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Eurostat collects migration data from national statistical institutes who remain free to use any appropriate data sources, according to national availability and practice, as long as they adhere to the harmonised definitions of migration statistics in Regulation (EC) No 862/2007. Member States generally base their migration flow data on administrative sources, sample surveys, census data, mirror data, mathematical methods or a combination of data sources.

18.2. Frequency of data collection | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Data are collected annually. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
18.3. Data collection | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
National statistical institutes collect the statistics and send them to Eurostat. Data are requested from national statistical institutes as part of the unified demographic data collection. The unified demographic data collection contains both mandatory and voluntary data (see section 3.1. Data description). |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
18.4. Data validation | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
The validation checks carried out on raw data sent to Eurostat by the national statistical institutes are either checks of internal consistency within each table, or checks of external consistency between different tables reporting the same data differently disaggregated. Eurostat also asks data providers to supply specific metadata describing the definitions used and the quality of the statistical outputs to assess uniform standards. To ensure the consistency and comparability of the statistics produced, Eurostat checks if the data it receives are consistent internally and over time, and if they are in line with the principles of the European Statistics Code of Practice and Regulation (EC) No 223/2009 on European statistics. For more information on data validation by Eurostat see http://ec.europa.eu/eurostat/data/data-validation. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
18.5. Data compilation | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Migration variables In the context of the annual demographic balance, Eurostat produces net migration figures by taking the difference between total population change and natural change at EU level. This is referred to as net migration plus statistical adjustment. The statistics on ‘net migration plus statistical adjustment’ are affected by the impact of adjustments (statistical inaccuracies, or methodological differences in the two components of this equation), as compared to ‘net migration’ (immigrants minus emigrants) that are affected by the impact of mirror errors (comparison between two independent measurements of the same migration flow, one reported by the receiving and one by the sending country). In theory, intra-EU migration statistics based on the 12-month time criterion should be fully comparable among reporting countries. The number of emigrants from Member State A to Member State B, as reported by A, should be almost equal to immigrants into B from A, as reported by B. However, care should be taken when comparing intra-EU migration statistics. National data suppliers can have different practices and are free to use any appropriate data sources available. There may therefore be discrepancies. Migration flow data are largely based on administrative data sources. Population register systems recording migration movements of people into and out of the countries concerned differ greatly from country to country. The propensity to register and de-register is also an issue. |
