Eurostat, The Statistical Office of the European Union

F2: Population

European Commission, 2920 Luxembourg LUXEMBOURG

The annual Eurostat's collections on population are structured as follows:

Data referring to population on 31st December of the reference year are transmitted by the Member States to Eurostat under the Regulation 1260/2013 on European demographic statistics. The data are conventionally published by Eurostat as 1 January of the following year (reference year + 1).

The annual demography data collections aim at collecting from the National Statistical Institutes both mandatory data and voluntary data. The mandatory data are those defined by the legislation listed on "6.1. Institutional Mandate - legal acts and other agreements".

The demographic data collected on voluntary basis depend on the availability and on the completeness of information reported by the National Statistical Institutes.

For more specific information on mandatory/voluntary data collection see 6.1. Institutional Mandate - legal acts and other agreements.

The following population statistics are available:

Population on 1 January split by:

- broad age group, sex and NUTS3

- 5 year age group, sex and: citizenship, country of  birth, NUTS2 (under regional data), NUTS3 (under regional data)

- single age, sex and: educational attainment, marital status, broad group of citizenship, broad group of country of birth

- sex and: citizenship and broad group of country of birth, country of birth and broad group of citizenship, NUTS2 (under regional data)

Population structure statistics: median age of population, proportion of population by various age groups, old age dependency ratio.

Following classification systems are used:

- International standard classification on education (ISCED)

- Nomenclature of territorial units for statistics (Nuts-2013)

- Human development index classification (http://hdr.undp.org/en)

Population on 1 January

Eurostat aims at collecting from the EU-28's 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). However, 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.

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.

Citizenship denotes 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.

Country of birth is 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.

Young age dependency ratio is the ratio of the persons aged 0-14 years old (1^st variant) or 0-19 years old (2^nd variant) divided by the number of persons conventionally considered of working age (respectively aged 15-64 (1^st variant) or 20-59 years old (2^nd variant)).

Old age dependency ratio is the number of persons of an age when they are conventionally considered economically inactive (aged 65 years and over (1^st variant) or 60 years and older (2^nd variant) to the number of persons conventionally considered of working age (respectively aged 15-64 (1^st variant) or 20-59 years old (2^nd variant)).

The total age dependency ratio is the sum of the young and old age dependency ratios. 

Median age of population

The age that divides a population into two numerically equal groups, meaning half the people are younger than median age and half are older.

Open-ended age class concept (Y_OPEN code) is a solution for presenting different open-ended age classes for data on population that are reported by the countries.

The open-ended age classes for data on population are the following: 85 and over (+), 90+, 95+, 99+, 100+ with the exceptions:

• Bulgaria: 80+ for the years 1994, 1995 and 1996
• Cyprus: 80+ for the years 1990, 1991 and 1992
• Turkey: 75+ for the years 2009, 2010 and 2011

Open-ended age class contains all the people aged more than the last single age for which a country can report. For example, if a country can provide data on its population by single year of age up to 94 years old, the ''open ended age class'' contains population 95 years old and over.

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

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

d) Other countries: Andorra, Armenia, Azerbaijan, Belarus, Bosnia and Herzegovina, Georgia, Moldova, Russian Federation, San Marino, Kosovo (under UNSCR 1244) and Ukraine.

e) 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.

The available time series collected and published in Eurostat database varies with the population breakdowns, with the longest time series starting in 1960 for national data and 1990 for regional data, and continuing to the latest available reference year.

The completeness of the time series of the demography and migration statistics collected on voluntary basis before the entering into force of the regulations listed in "6.1 Institutional mandate – legal acts and other agreements" and of the statistics which continue to be supplied to Eurostat on voluntary basis today depends on the availability of data transmitted by the national statistical institutes.

Not applicable.

Population figures are disseminated in integer numbers and also as shares of various age groups in total population (see dataset on population structure indicators).

Data referring to population on 31 December of the reference year are transmitted by the 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).

Quality assurance is part of data processing. Statistical products and processes are systematically reviewed in compliance with Quality Assurance Framework of the European Statistical System.

According to Art. 12 of the Regulation (EC) No 862/2007, "starting August 2012 and every three years thereafter, the Commission shall submit a report to the European Parliament and the Council on the statistics compiled pursuant to this Regulation and on their quality".

Therefore, information about overall assessment of data quality procedures carried out by Eurostat on the implementation of Regulation (EC) No 862/2007 on Community Statistics on Migration and International Protection is comprised in the Report from the Commission to the European Parliament and the Council, from 30.7.2015. This report documents the degree of progress that has been made by Member States, together with the Commission (Eurostat), in the implementation of the Regulation (EC) No 862/2007 since the first report.

In addition, Art. 11 of Regulation (EU) No 1260/2013 states that the Commission shall also submit reports on its implementation, to the European Parliament and the Council as follows:

- first report by 31 December 2018

- second report by 31 December 2023

These reports are to evaluate quality of data transmitted by Member States and EFTA countries and data collection methods used and, if appropriate, should be accompanied by proposals designed for future improvement of legal framework for population and vital events statistics under this Regulation.

Population statistics are widely used for planning actions, monitoring and evaluating programmes in a number of policy areas in the social and economic fields, such as:

• Analysis of population ageing and its effects on sustainability and welfare
• Evaluation of fertility as a background for family policies
• Evaluation of the economic impact of demographic change
• Calculation of 'per capita' indicators
• Key input for the EU decision-making process, as population defines the weight of each Member State in the Qualified Majority Voting of the Council of the EU

No user' satisfaction surveys are carried out.

Statistical data completeness depends on the availability of raw data transmitted by the National Statistical Institutes.

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.

Note: The table above is based on statistics and metadata on population reported by the countries for 1 January 2015.

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 2011 and after take into account the results of the latest population census (held in 2011). The time series of populations between the previous census and 2011 was revised by end 2013 by some of the countries, taking into account Eurostat’s recommendation (for more information about data revision per country, see also 17. Data revision).

Over time there have been geographical changes for certain countries, as seen in notes by country:

• 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 1.1.2015.
• 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 1.1.2011, Belgium (BE) population figures at national level refer to all registered persons including asylum seekers.
• 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.
• Starting with 1.1.2012, the reported Estonian (EE) population includes the migration component, whereas this was not included before.
• Starting with 2010, Poland (PL) revised the methodology used to estimate the usual resident population. This is indicated by a flag b (break in series) in the figures for 2010.

The population figures transmitted by the national statistical offices to Eurostat in the framework of Demography domain may differ from those available in other domains such us National Accounts, Labour Force Survey or in the survey on Income and Living Conditions. The difference is given by the population coverage (see metadata specific to each domain).

See 8.1. Release calendar.

• The policy of ESTAT is to make updates as soon as data is received and at any time during the year.
• In conformity with Regulation (EC) No 205/2014 Member States shall inform the Commission (Eurostat) of any planned revision of the data supplied no later than one week before the release of the revised data in the Member State concerned.
• For Urespop collection see specific metadata: URESESMS

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.

The status of the data is indicated by using flags (flag p = provisional data; flag e = estimated; flag b = break in time series; flag f = forecast).

Population data are collected by Eurostat from National Statistical Institutes.

Data are collected annualy.

The annual population data collections are carried out by Eurostat from the National Statistical Institutes in order to collect updated data. The demographic data collections contain both mandatory and voluntary data (see 3.1. Data description).

Controls are carried out on raw data transmitted by the NSIs to check if the total of a variable is consistent with the breakdown by different variables. Consistencies between different breakdowns of the same variable are verified by cross validations.

Based on the detailed collected data, Eurostat is computing a series of demographic statistics. The regular calculated demographic indicators are further submitted to several validations concerning the most updated annual value but also the available time series. These validations include checking on the plausibility of the most updated annual value and on two consecutive annual values. Mathematical verifications using standard deviation and weighted average are applied, for example for breakdowns of the life expectancy by educational attainment.

For more information on data validation see: http://ec.europa.eu/eurostat/data/data-validation .

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.

For population structure statistics the geographical aggregates are calculated by applying the same method applied to an individual country. The input for calculation is the aggregated data described above. Therefore, for statistics like ''median age'' of EU is not the average of median age for individual countries. Instead, it is computed as median age across all Member States, meaning that 50% of the total EU population are younger and 50% of the total EU population are older than the median age.
