Reference metadata Information message

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.

Short metadata
Full metadata

These summary metadata refer to the first results on the main demographic developments in the year of reference.

Member States send to Eurostat the first results on the main demographic developments in the year of reference (T), containing the total population figure on 31 December of year T (further published by Eurostat as Population on 1 January of year T+1), total births and total deaths during year T. This data collection is defined  under Regulation 1260/2013 on European demographic statistics. Countries may also transmit to Eurostat, on voluntary basis,  provisional data on total immigration, emigration and net migration during the year (T).

Eurostat's data collection on the above figures is called DEMOBAL and it is carried out in June of each year. Eurostat publishes these first demographic estimates in July of each year in the online database, in the table Population change - Demographic balance and crude rates (demo_gind).

These first demographic estimates may either be confirmed or updated by Eurostat's demographic data collection taking place in December each year (called Unidemo), whereby countries submit detailed breakdowns (e.g. by age and sex) of their yearly population data, including data on migration, both at national and at regional level. The online table Population change - Demographic balance and crude rates (demo-gind) will be accordingly updated. This table includes the latest updates on total population, births and deaths reported by the countries, while the detailed breakdowns by various characteristics included in the rest of the tables of the Eurostat database (Demography domain and Migration, for example the Population by citizenship and by country of birth table) may be transmitted to Eurostat at a subsequent date.

The online table Population change - Demographic balance and crude rates (demo-gind) contains time series going back to 1960; data before 2013 were collected by Eurostat from the national statistical offices on voluntary basis.

The individual metadata files reported by the countries are attached to this metadata file.

Population on 1 January

Eurostat aims at collecting from the EU Member States data on population on 1 January. The recommended definition is the 'usually resident population' and represents the number of inhabitants of a given area on 1 January of the year in question (or, in some cases, on 31st December of the previous year). The population transmitted by the countries can also be either based on data from the most recent census adjusted by the components of population change produced since the last census, either based on population registers. (More detailed information is available in the national metadata files.)

Usual residence means 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. The following persons alone are considered to be usually residents of the geographical area in question:

  • those who have lived in their place of usual residence for a continuous period of at least 12 months before the reference time; or
  • those who arrived in their place of usual residence during the 12 months before the reference time with the intention of staying there for at least one year.

Average population

The average population is calculated as the arithmetic mean of the population on 1st January of two consecutive years. The average population is further used in the calculation of demographic indicators, like the crude rates per 1000 persons.

Population change

The difference between the size of the population at the end and the beginning of the period Specifically, it is the difference in population size on 1 January of two consecutive years. A positive population change is also referred to as population growth. A negative population change is also referred to as population decline.

The population change consists of two components: natural change and net migration.

Natural change of population

The difference between the number of live births and the number of deaths during the year. A positive natural change, also known as natural increase, occurs when live births outnumber deaths. A negative natural change, also named as natural decrease, occurs when live births are less numerous than deaths.

Net migration plus statistical adjustment

Net migration is the difference between the number of immigrants and the number of emigrants. In the context of the annual demographic balance however, Eurostat produces net migration figures by taking the difference between total population change and natural change; this concept is referred to as net migration plus statistical adjustment. The statistics on 'net migration plus statistical adjustment' are therefore affected by all the statistical inaccuracies in the two components of this equation, especially population change. From one country to another 'net migration p statistical adjustment' may cover, besides the difference between inward and outward migration, other changes observed in the population figures between 1 January in two consecutive years which cannot be attributed to births, deaths, immigration and emigration.

Population turnover

The total magnitude of changes in membership experienced by a population. It shows the 'gross' effect of the population components, by adding up gains (births and immigration) and losses (deaths and emigration) in a population, as compare to the population change which shows their 'net' effect. The population turnover consists of two components: natural turnover and migration turnover plus statistical adjustment.

Natural turnover

The sum of births and deaths numbers.

Migration turnover plus statistical adjustment

The sum of immigration, emigration numbers and the statistical adjustment reported in the population.

Crude rates

A crude rate is calculated as the ratio of the number of events to the average population of the respective area in a given year. For easier presentation, it is multiplied by 1000; the result is therefore expressed per 1000 persons (of the average population).

The table below presents a summary with the reported reference populations based on which statistics on population, births and deaths are tranmsitted by the national statistical institutes to Eurostat. Several countries place themselves in two categories, with justification in the national metadata files.

1'Usually Resident Population' as stated in Article 2 of Regulation 1260/2013.

2 'Legal Residence Population' is composed of those persons who are entitled to be settled in the country at the reference date, either by holding the national citizenship or by other authorization issued by national authorities.

3 'Registered Residence Population' is composed of those persons who are listed on one or more registers owned by national authorities at the reference date. Each registered person shall be counted only once.

4 only events occurring in the country

5 only events occurring in the country

Th statistical unit used is ''person'' as indicated in the online database or deductible from the title of tables or of the indicator.

Statistical population is total population as defined in 3.4. Statistical concepts and definitions.

The population statistics are disseminated by single country, by region and by aggregates of countries, as follows:

a) The Member States of the European Union and their regional structure as defined in the Nomenclature of territorial units for statistics

b) The EU candidate countries and their agreed Statistical Regions following the same rules as the Nomenclature of territorial units for statistics

c) The EU potential candidate countries and their agreed Statistical Regions following the same rules as the Nomenclature of territorial units for statistics

d) The EFTA countries and their agreed Statistical Regions following the same rules as the Nomenclature of territorial units for statistics

e) Other countries: Andorra, Armenia, Azerbaijan, Belarus, Monaco, Russian Federation, San Marino and United Kingdom.

f) The geographical aggregates European Union and Euro Area, on which the dissemination covers at least the current and the previous version of their composition, the European Economic Area (EEA) and the European Free Trade Association (EFTA).

For details on geographical changes over time see the notes by country under 15.2 Comparability over time.

National refers to the territory of a Member State within the meaning of Regulation (EC) No 1059/2003 applicable at the reference time.

Regional refers to NUTS level 1, NUTS level 2 or NUTS level 3 as defined in the Regulation (EC) No 1059/2003 and available according to the classification in force at the reference time; where this term is used in connection with countries that are not members of the European Union, "regional" means the Statistical Regions at level 1, 2 or 3, as agreed between those countries and the Commission (Eurostat), at the reference time.

Statistics from the UK are available only until the withdrawal of the country from the EU.

Data referring to population on 31 December of the reference year are transmitted by the EU Member States to Eurostat under the Regulation (EU) No 1260/2013 on European demographic statistics. The data are conventionally published by Eurostat as 1 January of the following year (reference year + 1).

The reference period for vital events data is the calendar year in which the events occurred.

The reference period for migration flow data is the calendar year in which the migration occurred.

Eurostat collects data from the National Statistical Institutes. Information on data accuracy by country is available in the country metadata files. Please see the summary table below.

Population and Migration Estimates

The population and migration estimates are subject to revision following the publication of the Census of population.  Ireland conducts a Census every 5 years and the most recent detailed results are available from April 2022.  Following the publication of Census 2016 the 2022 population estimate required an upward adjustment of 52,300 (see table below). Note that this table details information on the revisions to the April reference time and for the first time includes people from households that were fully absent temporarily and outside Irealnd on Census night. 

 See national metadata for more information. 

Births must be registered within 3 months.

Deaths must be registered within 3 months but there may be delays if a corenor is involved.

ES

Population is compiled in the Continuous population statistics, based on the information provided by the administrative data of the Municipal Register and by other statistics already compiled, such as the population censuses and the statistics relating to births and deaths, and therefore, the accuracy of its results depends on the accuracy of the information sources used. 

Delays in the delivery of the information from some Civil Registers and lack of information in some variables from the register bulletin. This produces a non-response rate of approximately 0,1%

This non-response is treated through information from the Ministry of Justice

Live births data are fully comprehensive and reliable. The proportion of unknown data of mothers is low (except for their occupation). This share among fathers is higher, especially in case  of extramarital live births. On live births abroad only basic data are available.

Data related to deaths in Hungary are fully comprehensive and accurate. Deaths of persons with address in Hungary occured abroad are also registered, but in a less detailed manner.

Immigration data of foreign and national citizens is comprehensive and reliable, containing all persons legally entering and residing in the country. Return migration of nationals might be underestimated due to the lack of registration.

Data of national emigrants might be underestimated due to the lack of deregistration.

There are three sources of errors to figures in the National Register of Persons on 31 December: late notifications of change of residence, late death certificates, and late birth reports. In a survey of delayed reports over the past five years it emerged that the greatest uncertainty was caused by late notifications of change of residence, due to which an average of 80 persons are under- or overestimated in the National Register of Persons on 31 December. Late death certificates cause the number of persons to be overestimated by around 10 persons in the National Register of Persons on 31 December, while late birth reports cause the number of persons to be underestimated by one individual about every two years.

Delayed birth reports were for a short period the main cause of errors in birth figures. In a review of delays to birth reports over the last five years it emerged that no birth report was missing.

Information on the number of deaths published in the tables of Statistics Iceland is accurate; it can be considered certain that information on all deaths reaches Statistics Iceland.

Late registration of change of residence is the main cause of errors in migration figures.

Migration is calculated for each month and thus a final figure is available for each month on its own; the figures for that month are not changed at any point after that. If a change of residence is registered a month or more late it is added to the month during which it was received.

When considering all moves over the past five years (from 1996-2000) only around 55% of registrations were received within a month of moving. After two months 96% of all registrations had been received by Statistics Iceland and within six months 98% had been received.

Errors in published migration data appear due to delays in registration of change of residence.

NO


Some errors made during the collecting and processing of the data are unavoidable and include coding, revision and data processing errors etc. Extensive efforts have been made to minimize these errors, and we regard these types of errors to be relatively insignificant.

Dropout errors will be found to the extent there are persons staying in Norway not being registered as residents according to the regulations. We refer to point 4.1. Definitions of the main concepts and variables.

None because all the material rather than samples is used.

The quality of the basic data from the National Population Register is generally very good for statistical purposes. One minus is nevertheless residence registration - in part because too many are registered as residents, but also because certain groups are registered as having another domicile than where they actually live. This is particularly true because according to the rules unmarried students are listed as residing with their parent(s).



The quality of the birth reports is generally very good and there is very little delay in the reporting process.

 The quality of the death  reports is generally very good and there is very little delay in the reporting process.

 

Few reasons for unreliability.

 

Missing or delayed emigration notifications make the statistics less reliable in the short run.  In the long run all emigrants will be discovered and registers as such.

Emigration to a Nordic country is caught by the country of immigration and reported to Norway.

Due to lack of data on international migration, which should certainly be included in calculation of annual population estimates, it may be supposed that population estimates are not completely reliable data. But, the experience shows that population estimates from the intercensus period follows the trend of population.

Population, births and deaths figures are disseminated in integer numbers.

A crude rate is calculated as the ration of the number of events to the average population of the respective area in a given year. For easier presentation, it is multiplied by 1000: the result is therefore expressed per 1000 persons (of the average population).

Based on the national detailed figures on population and other demographic events transmitted by the National Statistical Institutes, Eurostat derives/calculates demographic variables and geographical aggregates by applying common calculation method.

Geographical aggregation

For population data expressed in number, the geographical aggregation is done by arithmetical sum, when there are no missing values among the components of the respective geographical aggregate. Otherwise, they are not calculated.

Demographic data are collected by Eurostat from the National Statistical Institutes.

For a summary of the national sources of data please see the countries' individual metadata files or the summary table in annex.

Population 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 demographic indicators are accordingly revised.

Dissemination is made in line with the 8.1 Release calendar and with 17.1 Data revision-policy.

For timeliness of data release see 8.1 Release calendar.

The recommended definition of the 'population' for the statistics on population reported under Article 3 of the Regulation 1260/2013 and under Article 3 of the Regulation 862/2007 is the 'usually resident population' meaning all the persons having their usual residence in a Member State at the reference time. Where the circumstances described above cannot be established, 'usual residence' can be taken to mean the place of legal or registered residence.

Comparability over time could be disturbed by breaks in data series. The breaks in population series due to methodological, data processing changes or revisions in population counts reported by the countries are documented in Eurostat’s database with the flag b (break in series).

The population data for the year 2021 and after take into account the results of the latest population census (held in 2021-2022). Following Eurostat’s recommendations to ensure consistency of statistics over time, several Member States (Bulgaria, Germany, Ireland, Greece, Spain, Croatia, Italy, Cyprus, Lithuania, Hungary, Malta, Poland, Portugal) have revised or are in process of revising their population time series between the reference years of the population and housing censuses held in 2011 and 2021. The revisions are expected to be published in Eurostat's tables by end of 2024. While the processing of population revisons is ongoing, it may happen that EU aggregates are not fully syncronised with the corresponding sum of countries. For more information about data revision per country, see also 17. Data revision and the national metadata reported by each country.

Over time there have been methodological and geographical changes for certain countries, see the notes below:

  • FX stands for Metropolitan France, including Corsica, excluding the overseas departments (DOM).
  • FR stands for the whole France, including the overseas departments (DOM). Data on Saint Barthelemey are excluded starting with 1.1.2012. Data on Mayotte are included starting with the statistics on vital events for the reference year 2014 and with the statistics on population on 1.1.2014.
  • The European geographical aggregates (EU, EA and EEA) include FX until 1997 and FR from 1998 on. This change is indicated by a flag b (break in series) in the EU statistics for 1998.
  • The time series for Germany (DE_TOT) refer to the Federal Republic within its frontiers after 3 October 1990.
  • Starting with 1.1.1975, data for Cyprus (CY) refer to the government-controlled area.
  • Up to 1.1.2000, population data for Malta (MT) refer to the Maltese population only while, starting with 2001, figures include also foreign residents. This is indicated by a flag b (break in series) in the figures for 2001.
  • Starting with 1.1.2010, the statistics on the permanent resident population of Switzerland (CH) includes all persons in the asylum process who have been residing in Switzerland since 12 months or more. The change appears in Eurostat population figures starting with population reported for 1.1.2011.
  • Starting with 1.1.2010, Poland (PL) revised the methodology used to estimate the usually resident population. This is indicated by a flag b (break in series) in the figures for 2010.
