Basic data of the statistics
Data description
The statistics on changes in marital status describe the numbers of marriages, divorces, registered partnerships and divorces from a registered partnership as well as the change of each marital status with the help of indicators. The statistics also contain some data on becoming widowed. The statistics cover the beginnings and ends of marriages and registered partnerships in which at least one of the spouses or parties resides permanently in Finland at the time of the event according to the Population Information System maintained by the Digital and Population Data Services Agency and the State Department of Åland. The annual compiling of statistics on registered partnerships ends with the year 2017, given that as of 1 March 2017, same-sex couples entered into marriage due to an amendment made to the Marriage Act. The marital statuses are unmarried, married, divorced, widowed, in a registered partnership, divorced from a registered partnership and widowed from a registered partnership.
Statistical population
The statistical population consists of all marriages, divorces and divorces from a registered partnership in which at least one of the spouses or parties resided permanently in Finland at the time of the event according to the Population Information System.
Statistical unit
Vital events, which include a marriage contracted, divorce, divorce from a registered partnership and the individuals involved in the aforementioned events. The individuals involved in a vital event have a personal identifier. The personal identifier is an identifier in personal data sets. The personal identifier allows for linking background information to the individual from other data sets.
Unit of measure
The number of vital events.
In indicators per mil, i.e. the number of vital events or individuals involved in such an event proportioned to the mean population of the part of population susceptible to the event per 1,000 individuals.

Reference period
The reference period of statistics is a calendar year.
Reference area
Data on Finland are available on a countrywide level and according to various regional divisions based on Finland’s division into municipalities.
The classification into regions and the statistical grouping of municipalities have been used since 1997. Prior to this, provinces were used instead of regions and forms of local government instead of the statistical grouping of municipalities. As of 1999, the statistics on changes in marital status have used the regional division which has entered into force at the beginning of the calendar year following the statistical year.

Sector coverage
As of 2017, the statistics include all marriages, divorces and divorces from registered partnerships in which at least one of the spouses or parties resided permanently in Finland on the date of the event according to the Population Information System.
From 2002 to 2017, the statistics also included the registered partnerships which began each year in which at least one of the parties resided permanently in Finland on the date the partnership was confirmed.
The statistics contain several universal details on the individuals whom the aforementioned vital events concern, such as age, marital status and previous marital status, native language, municipality of residence, municipality of birth, country of birth, country of residence, nationality, number of children and the sequence number of the marriage or registered partnership. They also contain data on the date related to each change in marital status, such as the date on which a couple entered into marriage or registered a partnership, or the date on which a marriage or registered partnership ended in divorce. In addition, the statistics include data related to a particular change only, such as the manner in which a marriage was entered into and the date on which a previous marriage was dissolved.

Time coverage
Comparable regional vital event time series are available free of charge as of 1990. The tables always indicate the regional division used.
Data on the number of marriages entered into per year are available as of 1749. Data on divorces began to be collected annually following the statistical reform in 1877.
The amendment to the Marriage Act, as of which same-sex couples have married and the registration of partnerships ended, came into force on 1 March 2017. Among other things, the amendment meant that, as of 2017, the total number of annually contracted marriages is composed of marriages in which the couples may be of the opposite sexes or of the same sex. The aforementioned also applies to divorces.
The total number of marriages entered into annually from 1980 to 2016 was composed of marriages in which the wife resided permanently in Finland. Starting from 2017, the total number of opposite-sex marriages contracted also includes marriages entered into where only the husband is permanently residing in Finland at the time the marriage was contracted. When applying the new calculation method it is possible to tabulate comparable numbers of opposite-sex marriages contracted retrospectively starting from 1990. The aforementioned also applies to divorces.

Frequency of dissemination
Unless otherwise mentioned, a calendar year’s final statistics are completed in April or May of the following calendar year. The final statistics are published on the website of Statistics Finland.
Preliminary data on the numbers of marriages and divorces are released monthly on Statistics Finland’s website under Preliminary population statistics.

Concepts
Age
In connection with vital events, age data refer to the age on the day the event took place. Average age is obtained by adding up the ages of all persons involved in the same event at the time of the event, after which the sum is divided by the number of these persons. As the used age of a person is given in full years at the time of the event, it is not the exact age of that person. For this reason, it is assumed when computing average age that the persons were aged x+0.5, on average, at the time of the event.
Age-specific marriage rate
The age-specific marriage rate indicates the number of married women per 1,000 non-married women of the mean population in the age group in question.
Age-specific remarriage rate
The age-specific remarriage rate indicates the number of second or higher order marriages contracted by women per 1,000 women that have previously been married in the age group in question.
Crude divorce rate
The crude divorce rate refers to the number of divorces per 1,000 persons of the mean population.
Crude marriage rate
The crude marriage rate refers to married women per 1,000 of the mean population.
Crude remarriage rate
The crude remarriage rate refers to the number of second or higher order marriages contracted by women per 1,000 previously married women of the mean population.
Divorce
The divorce statistics are based on data on granted decrees of divorce transmitted to the Digital and Population Services Agency (former Population Register Centre) by courts of law. The statistics also include cases where a permanent resident of Finland is granted a divorce by a foreign court. If the divorce is granted abroad, it must be reported to the register keeper for registration of divorce. Exceptions are divorces granted to Finnish citizens in Sweden, on which the Swedish register keeper notifies the Finnish counterpart directly.
In 1980 to 2016, divorces referred to divorces of women living permanently in Finland unless otherwise stated. Starting from the statistical reference year 2017, divorces where at least one of the spouses has resided permanently in Finland on the day the divorce was granted are included in the statistics as divorces. The amendment to the Marriage Act that entered into force on 1 March 2017 enabled same-sex couples to enter into marriage (156/2015). Since 2017, the total number of divorces consists of the number of divorces of marriages between opposite-sex and same-sex couples.
The amendment to the Marriage Act (411/1987), effective from 1 January 1988, simplified divorce proceedings. Divorce figures began to rise towards the end of 1988, when the first divorces (after a reconsideration period of six months) became effective under the new legislation. The Marriage Act no longer has regulations on 'cancellation of marriage' or 'nullification of marriage'. Before the new act came into force in 1988 these were in separate groups, now among divorces.

Language
Information on language is obtained from the Population Information System. At the same time as parents register the name of their new-born, they also indicate the child's mother tongue. That language is retained in the Population Information System unless it is changed upon separate application.
Languages are classified by the Population Register Centre according to the ISO 639 standard. The future language classification ISO-639-1 was already adopted for the 2000 population census.

Marriage
Starting from the statistical reference year 2017, contracted marriages refer to marriages where at least one of the spouses has resided permanently in Finland on the day when the marriage was contracted. The amendment to the Marriage Act that entered into force on 1 March 2017 enabled same-sex couples to enter into marriage (156/2015).
The number of marriages contracted annually is, thus, the number of marriages entered into by same-sex and opposite-sex spouses.
In 1980 to 2016, contracted marriages referred to marriages of women living permanently in Finland unless otherwise stated.
As a result of the amendment to the Marriage Act, starting from 1 June 2019, a person under 18 years of age shall not marry in Finland (351/ 2019).

Mean population
The notion of mean population (or average population) refers to the average of the populations of two consecutive years. When a ratio describing some phenomenon is calculated for the statistical year, the number of events in the phenomenon in question is usually expressed as a proportion of the mean population of the people or the groups subject to the event. The figures relating to population events are generally given as per 1,000, that is, the result of the division is multiplied by one thousand.
Registered partnership
Registered partnership of two persons of the same sex aged 18 or over (Act on Registered Partnerships of 9 Nov. 2001/950). Partnership is registered by an authority entitled to perform civil marriage ceremonies. Registered partnership is dissolved when one partner dies or is declared dead, or when it is dissolved by court order.
The possibility to register partnerships started in Finland on 1 March 2002 and ended on the last day of February 2017 (Act to amend the Act of Registered Partnerships 250/2016). Starting from the beginning of March 2017, same-sex couples have been able to enter into marriage (156/2015).
As a result of the amendment to the Marriage Act, parties to a partnership registered in Finland can convert their partnership into a marriage by making a joint notification of this to the Digital and Data Services Office. A registered partnership continues as a marriage from the day on which the Digital and Data Services Office has received the notification.
In the statistics, registered partnerships that have been converted into marriages based on such notification are not included as contracted marriages in the annual statistics.

Sex
The information about sex has been obtained from the Population Information System.
Sex/gender
Data on sex are obtained from the gender entry in the Population Information System maintained by the Digital and Population Data Services Agency.
According to the Act that entered into force on 3 April 2023, the gender entry in the Population Information System can be changed upon application including an explanation that a person permanently identifies as the gender they seek recognition for (Act on Legal Recognition of Gender 295/2023).
In Finland, only male or female can be entered as gender in the Population Information System. If a person who moves to Finland from abroad has a third or unspecified gender, the person is recorded as female in the Population Information System.

The probability of divorce
The probability of divorce for women’s first marriages where the spouses are of opposite sexes is produced by applying multistate life tables. The life tables are based on women's age-group specific marriage, mortality, widowhood and divorce rates in the statistical reference year regardless of the husband's age or whether the marriage is the first one or not for him.
Total marriage rate
The total marriage rate describes the proportion of women (generally per 100 or 1,000 persons) that contract marriage in their lives, on condition that none of them die and that the marriage rate in the pertinent cohort remains constant throughout the period when these women belong to the age groups of 15 to 49 years. It is computed by adding up the age-specific marriage rates of first marriages in the whole age period. For the age-specific marriage rate a ratio is calculated between the number of women contracting marriages and all the women in the age group and not only the non-married ones.
Accuracy, reliability and timeliness
Overall accuracy
The data of the statistics on changes in marital status represent total data. The data are as good as the quality of the Population Information System maintained by the Digital and Population Data Services Agency. This means that all marriages, divorces and registered partnerships ending in divorce in which at least one of the spouses or parties resided in Finland permanently on the day of the marriage or the day on which the divorce was granted are recorded in the system. The individual officiating at a wedding must inform the Population Information System of the marriage without delay. (Decree 820/1987)
Courts of law enter data on the divorces they grant and on registered partnerships ending in divorce in the Population Information System.
The Population Information System maintained by the Digital and Population Data Services Agency and the State Department of Åland can be regarded as very exhaustive in terms of persons. For an individual to receive a personal identity code, they must be registered in the Population Information System. Living in Finland without a personal identity code is practically impossible. Legal employment, the opening of a bank account, taking care of affairs with the authorities, etc. all require a personal identity code.
Following the discontinuation of census registration as of 1989, the Population Information System has been maintained solely with reports on vital events. The accuracy of these is indicated by the address reliability survey carried out within the Population Information System.
The Population Register Centre has commissioned a sample survey on the accuracy of addresses from Statistics Finland. Approximately 11,000 individuals are contacted and inquired whether their address in the Population Information System is accurate. In the latest survey, in 2012, the address of 98.9 per cent of the respondents was accurate.
In connection with municipal elections, returned notifications of voting sent to foreigners usually reveal around 1000 persons who have moved from the country without giving notice and are thus still included in the Finnish population.

Timeliness
The data are published approximately four months after the reference period.
Punctuality
The data are almost invariably released on the target date, due to which there has been no time delay. If the release of statistical data is significantly delayed from the announced point of time, information about the delay is posted on the statistics’ home page.
Comparability
Comparability - geographical
Comparisons based on numbers can be made regionally between different years when the effect of regional mergers are considered. It is common practice that the entire time series is updated to the temporally most recent regional division. The marriage rate or divorce rate in different areas can be compared when the numbers are set in proportion to the population. Statistics describing regional marriage rates and divorce rates within the country are comparable once the effect of the regions’ different age structures has been removed by means of age standardisation.
The definitions of entering into marriage and divorce comply with international recommendations. However, there may be some differences between countries, due to which the definitions must be reviewed before comparison between countries. The age at which marriage can be entered into can differ between countries, for example.
In addition, different countries may have different definitions for compiling statistics on marriages and divorces as having taken place in the country. In one country, for instance, all cases in which both spouses resided in the country permanently when they married or divorced can be included in the statistics. In another country, the definition may be broader, in which case all cases in which at least one of the spouses resided in the country permanently when they married or divorced are included in the statistics.

Comparability - over time
Vital event data on the number of people entering into marriage are available as of 1749. Data on divorces began to be collected annually following the statistical reform in 1877.
Following an amendment to the Marriage Act, same-sex couples have been permitted to get married and the registration of partnerships was abandoned as of 1 March 2017. This meant that, as of 2017, the total number of annually contracted marriages is composed of marriages in which the couples may be of the opposite sexes or of the same sex. Likewise as of 2017, the total number of divorces consists of divorces in which the spouses may be either of the opposite sexes or the same sex.
The total number of marriages or divorces annually from 1980 to 2016 was composed of marriages or divorces in which at least the wife resided permanently in Finland. As of 2017, the total number of marriages or divorces by couples of opposite sex have also included those in which only the husband resides permanently in Finland at the time the marriage is entered into or the divorce is granted. By applying the new computing method, it is nevertheless possible to retroactively tabulate comparable numbers of marriages entered into or divorces by opposite-sex couples as of 1990.
When tabulating data on changes in marital status by area, such as by municipality, cases in which the couple resides permanently in Finland, but the spouses’ or partners’ municipalities of residence at the time of the event are not the same, the municipality of residence selected in a vital event between opposite sexes is the woman’s, and in a vital event between a same-sex couple, the younger spouse’s or partner’s municipality of residence. The principle of the procedure is the same as before. In other cases, the municipality of residence selected is that of the spouse or partner who resides permanently in Finland.
Data on the number of registered partnerships confirmed and divorced from are available from 2002 to 2017 and from 2002, respectively. Data on the number of same-sex marriages and divorces are available as of 2017.

Coherence - cross domain
The data of the population statistics are used as basic data for population in the other statistics of Statistics Finland. Thus, different statistics of Statistics Finland are consistent with each other as regards population data.
Coherence - internal
Preliminary data on vital events in the population statistics have been published since the 1970s. The preliminary statistics serve as an important point of reference with regard to the final statistics. The number in the final statistics does not usually differ from the preliminary statistics in a material way. On the one hand, there is demand for preliminary data when monitoring the phenomenon’s development, and on the other, society uses the data in its operations.
The final statistics depart from the preliminary statistics mainly in that the data in the final statistics are reviewed in more detail than those in the preliminary statistics and in that the final statistics contain more variables describing the phenomenon.

Source data and data collections
Source data
The data of the statistics on changes in marital status represent total data. They are based on data obtained from the Population Information System on a weekly basis. The Digital and Population Data Services Agency and the State Department of Åland maintain the Population Information System by storing the data they receive on changes in the population living in the country there.
The data stored in the Population Information System are specified in the Act (21 August 2009/661) on the Population Information System and the certificate services of the Digital and Population Data Services Agency.

Data collection
As of 1975, Statistics Finland has obtained population data weekly in machine-executable form from the Population Information System maintained by the Digital and Population Data Services Agency and the State Department of Åland. The acquisition of data is based on Statistics Finland's position as a statistical authority as decreed in law.
Frequency of data collection
The data for the statistics are collected annually.
Methods
Data compilation
The statistics on changes in marital status represent total data.
The data include underlying variables from which data may be missing.
Insofar as possible, the data are filled in using population data and the Population Information System.

Data validation
The number of marriages contracted, divorces and the divorces of registered partners are compared with the corresponding figures in the preliminary statistics.
The data are checked for double rows.
The data are checked for cases which would have been included in the data of previous years.
The direct distributions of variables are verified and the values of variables are examined to check whether they accord with classifications.
Missing cases are investigated. Data are searched for in other population data sets and ultimately in the direct access service of the Population Information System.
The logic of variables is checked by cross-tabulation.

Legal acts and other agreements
The compilation of statistics is guided by the Statistics Act. The Statistics Act contains provisions on collection of data, processing of data and the obligation to provide data. Besides the Statistics Act, the Data Protection Act and the Act on the Openness of Government Activities are applied to processing of data when producing statistics.
Statistics Finland compiles statistics in line with the EU’s regulations applicable to statistics, which steer the statistical agencies of all EU Member States.
Further information: Statistical legislation
Confidentiality - policy
The data protection of data collected for statistical purposes is guaranteed in accordance with the requirements of the Statistics Act (280/2004), the Act on the Openness of Government Activities (621/1999), the EU's General Data Protection Regulation (EU) 2016/679 and the Data Protection Act (1050/2018). The data materials are protected at all stages of processing with the necessary physical and technical solutions. Statistics Finland has compiled detailed directions and instructions for confidential processing of the data. Employees have access only to the data essential for their duties. The premises where unit-level data are processed are not accessible to outsiders. Members of the personnel have signed a pledge of secrecy upon entering the service. Violation of data protection is punishable.

Confidentiality - data treatment
In population statistics, the identification data of an individual are pseudonymised, that is, the data of a person can no longer be linked to a specific person without additional information. In accordance with data protection practices, rules concerning less detailed data are applied when distributing data by area if the table contains variables specified as sensitive. In such cases, figures remaining below the limit value are not reported or divided into the categories of the sensitive variable.
According to the Statistics Act, data released for research use must be edited into a form from which statistical units cannot be identified directly or indirectly. To prevent indirect identification, variables key to identification must be modified with statistical data protection methods suitable for the situation.
The most important data protection method is the disclosure of a sample rather than the total data.
In addition to samples, the data limiting methods used by Statistics Finland include aggregating the classification of variables, removing variables and hiding the variable values of a single unit.

Data sharing
Statistics Finland’s task is to compile statistics and reports describing conditions in society (Statistics Finland Act of 24 January 1992/48). These also include population statistics, one of which is the statistics on changes in marital status. The compiler of the population statistics is determined by Statistics Finland’s valid rules of procedure.

Accessibility and clarity
Statistical data are published as database tables in the StatFin database. The database is the primary publishing site of data, and new data are updated first there. When releasing statistical data, existing database tables can be updated with new data or completely new database tables can be published.
In addition to statistical data published in the StatFin database, a release on the key data is usually published in the web service. If the release contains data concerning several reference periods (e.g. monthly and annual data), a review bringing together these data is published in the web service. Database tables updated at the time of publication are listed both in the release and in the review. In some cases, statistical data can also be published as mere database releases in the StatFin database. No release or review is published in connection with these database releases.
Releases and database tables are published in three languages, in Finnish, Swedish and English. The language versions of releases may have more limited content than in Finnish.
Information about changes in the publication schedules of releases and database tables and about corrections are given as change releases in the web service.
Data revision - policy
Revisions – i.e. improvements in the accuracy of statistical data already published – are a normal feature of statistical production and result in improved quality of statistics. The principle is that statistical data are based on the best available data and information concerning the statistical phenomenon. On the other hand, the revisions are communicated as transparently as possible in advance. Advance communication ensures that the users can prepare for the data revisions.
The reason why data in statistical releases become revised is often caused by the data becoming supplemented. Then the new, revised statistical figure is based on a wider information basis and describes the phenomenon more accurately than before.
Revisions of statistical data may also be caused by the calculation method used, such as annual benchmarking or updating of weight structures. Changes of base years and used classifications may also cause revisions to data.
