Data on marriages and divorces at national level are transmitted by the National Statistics Institutes on voluntary basis in the context of the annual demographic data collections in the field of demography carried out by Eurostat as follows:

The UNIDEMO questionnaire collects annual mandatory and voluntary demographic data from the National Statistical Institutes.

The completeness of the demographic data collected on a voluntary basis depends on the availability and completeness of information provided by the National Statistical Institutes.

 The following statistics on marriages and divorces are collected from the National Statistical Institutes:

• Marriages by previous legal union status of marrying persons;
• First-time marrying persons by age, year of birth and sex;
• Marriages by country of citizenship of marrying persons;
• Marriages by country of birth of marrying persons;
• Divorces by duration and year of the marriage;
• Divorces by country of citizenship of spouses;
• Divorces by country of birth of spouses.

Statistics on marriages and divorces: based on the different breakdowns of data on marriages and divorces received, Eurostat produces the following:

• Statistics available in the online table Marriage indicators (demo_nind):

- Total number of marriages;

- Crude marriage rate;

- Mean age at first marriage – male;

- Mean age at first marriage – female;

- Total first marriage rate – male;

- Total first marriage rate – female;

- Proportion of first marriages – male;

- Proportion of first marriages – female.

• Statistics available in the online table Divorce indicators (demo_ndivind):

- Total number of divorces;

- Crude divorce rate;

- Divorces per 100 marriages.

Not applicable.

Not applicable.

Crude marriage rate : the ratio of the number of marriages during the year to the average population in that year. The value is expressed per 1000 inhabitants.

Crude divorce rate: the ratio of the number of divorces during the year to the average population in that year. The value is expressed per 1000 inhabitants.

Legal marital status: marital status is the legally defined marital state.

Mean age at first marriage: the mean age of men and women when they get married for the first time.

First marriage rates: the ratio of the number of first time marrying person of age x to the average population of age x, separately for men and women.

Total first marriage rate: it is computed by adding the first marriage rates by age in a given year, separately for men and women.

Proportion of first marriages: the ratio of the number of first time marriages in the total number of marriages in a given year, by sex.

Divorces per 100 marriages: the ratio between the number of divorces (independently of the duration) and the number of marriages in a given year.

Age and duration definition:

Most National Statistical Institutes of the EU Member States provide data on the number of first marriages by both dimensions: age and year of birth of the first-time marrying persons. First marriage statistics are compiled and disseminated, based on the data collected, only by age at last birthday (also referred as age completed).

Most National Statistical Institutes of the EU Member States provide data on the number of divorces by both dimensions: duration and year of marriage. Divorces are compiled and disseminated, based on data collected, only by duration of marriage reached during the year.

Eurostat uses the concept of age completed when calculating marriage indicators.

The statistical unit used is ''number'', as indicated in the online database or by the title of tables.

The statistical population is the total population. For more information on the population concepts used, please see the reference metadata on Population.

Marriage and divorce statistics are disseminated as available by single country and by aggregates of countries, as follows:

a) EU member countries

b) EU candidate countries.

c) European Free Trade Association (EFTA) countries

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 (dissemination covers at least their current and previous form), the European Economic Area (EEA) and the EFTA.

For details on geographical changes that have taken place over time, see the notes by country under 15.2 Comparability over time.

The time series compiled and published in the Eurostat database varies, depending on the breakdowns, with the longest time series starting in 1960 and continuing through to the latest available reference year.

The completeness of the time series for marriage and divorce statistics collected on a voluntary basis depends on the availability of data sent to Eurostat by the National Statistical Institutes.

Not applicable.

Data on marriages and divorces are disseminated as integer number and as rates.

The reference period for marriage and divorces data is the calendar year in which the events occurred.

Data are collected on voluntary basis.

Not applicable.

Regulation (EC) No 223/2009 on European statistics (recital 24 and Article 20(4)) of 11 March 2009 (OJ L 87, p. 164), stipulates the need to establish common principles and guidelines ensuring the confidentiality of data used for the production of European statistics and the access to those confidential data with due account for technical developments and the requirements of users in a democratic society and Amending Regulation (EU) No 2015/759 of 29 April 2015 as regards the violation of statistical confidentiality.

Marriage and divorce data are based on the legal civil status as recognised by the law of each country.

Breaks in data series could compromise comparability over time. Any breaks in data series due to changes in methodology and data processing or revisions to data counts reported by the countries in question are documented in the Eurostat database using flag b (break in series).

The population data for 2011 and beyond 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 some countries at the end of 2013, taking Eurostat’s recommendation into account (for more information about data revision per country, see 17. Data revision).

Over time, certain countries have been subject to geographical changes (see below):

• FX stands for Metropolitan France, including Corsica and excluding the overseas departments (DOM).
• FR stands for France as a whole, including the overseas departments (DOM). Data on Saint Barthelemey are excluded as of 1.1.2012. Data on Mayotte are included, starting with the statistics on vital events for the reference year 2014 and the statistics on population on 1.1.2015.
• The European geographical aggregates (EU, EA and EEA) include FX up to 1997 and FR from 1998 onwards. This change is indicated by flag b (break in series) in the EU statistics for 1998.
• The time series for Germany (DE_TOT) refer to the Federal Republic of Germany after 3 October 1990.
• As of 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. However, as of 2001 figures also include foreign residents. This is indicated by flag b (break in series) in the figures for 2001.
• As of 1.1.2010, the statistics on the permanent resident population of Switzerland (CH) include all people in the asylum process who have been residing in Switzerland for 12 months or more. The change is reflected in Eurostat population figures starting with populations reported on 1.1.2011.
• As of 1.1.2011, Belgium (BE) national population figures refer to all registered people, including asylum seekers.
• As of 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.
• As of 1.1.2012, the reported Estonian (EE) population includes the migration component, whereas this was not included before.

These changes may affect also the statistics on marriages and divorces and are signalled by the flag b.

Eurostat’s policy on demographic statistics is to carry out updates as soon it receives data and at any time during the year.

Marriage and divorce statistics are continuously revised according to the most recent data released and sent to Eurostat by the National Statistical Institutes. The geographical aggregates and the demographic indicators are revised accordingly.

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

Data are collected by Eurostat from the National Statistical Institutes.

Data are collected annually.

The annual data collections are carried out by Eurostat using data provided by the national statistical institutes in order to publish updated statistics. The demographic data collections contain both mandatory and voluntary data (see 3.1. Data description).

Eurostat checks raw data sent by the national statistical offices to see if the total of a variable is consistent with the breakdown by different variables. It also does cross-checks to see if different breakdowns of the same variable are consistent.

Based on the detailed collected data, Eurostat calculates a series of demographic statistics. The demographic indicators calculated in the standard way are validated in the context of the available time series. The validation rules include checking the plausibility of the most up-to-date annual value and two consecutive annual values. Mathematical checks are carried out using standard deviations and the weighted average.

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

Based on the detailed national figures on population and other demographic events sent to Eurostat by the National Statistical Institutes, Eurostat derives/calculates demographic indicators and geographical aggregates using common calculation methods.

Geographical aggregation

For statistics on live births expressed in numbers, geographical aggregation is done by arithmetical sum if no values are missing from the components of the geographical aggregate in question. Otherwise the geographical aggregates are not calculated.

For rates, the geographical aggregates are calculated using the same method as for an individual country. The input for calculation is the aggregated data described above.
