Basic data of the statistics
Data description
Statistics Finland produces official statistics on municipal elections containing key data on the candidates, elected councillors, those entitled to vote, those who voted and support gained by the parties. Statistics Finland’s statistics pages on municipal elections also provide analyses on the backgrounds of the candidates and the elected, on those who voted in advance, and as separate services the election map service and the StatFin service (database tables / most detailed level is voting district).
Statistical presentation
Municipal elections are held every four years. Statistics Finland produces official statistics on municipal elections. Preliminary statistics are published on the Internet, in the StatFin database and on the Municipal Statistics page. The second data, i.e. the final data, are submitted to Statistics Finland after the confirmation of the election result. After the confirmation of the election result, the confirmed data will be published on the statistics page and the StatFin database tables will be updated.
Information on municipal elections can be found on the website of the statistics and in the StatFin database on Statistics Finland's website.
Statistics Finland receives the basic data for the elections from the Ministry of Justice.

Statistical population
The population of the statistics is the candidates nominated for the elections and persons entitled to vote in the elections.
Statistical unit
Statistical units are:
- candidate (person)
- elected councillor (person)
- party
- person entitled to vote (person)
- candidate (person)
- elected councillor (person)
- party
- person entitled to vote (person)
Unit of measure
The measurement units in the statistics are the number of persons (candidates, elected councillors and persons entitled to vote), the number of votes cast and the number of persons who voted, as well as the percentage shares.
Base period
No indices are published in the statistics.
Reference period
The statistics describe the year 2025 (April).
Reference area
The data materials cover entire Mainland Finland, on the level of constituencies, municipalities and voting districts.
Sector coverage
The data produced in the statistics have no connection with economic activities and thus cannot cover them at all.
Time coverage
The data materials of the statistics cover only the time of the elections concerned. Time series are published in the statistics on support for the parties and voting turnout by combining data materials.
Data published after the control calculation are final.
Data published after the control calculation are final.
Frequency of dissemination
The frequency of dissemination of the data is dependent on the frequency of elections. According to the normal schedule, municipal elections are held at four-year intervals, so the dissemination frequency of the statistics is every four years. It is also possible that elections are held more often than this, in which case the dissemination frequency of the statistics is correspondingly shorter than four years.
Concepts
Advance polling stationsExternal link
Advance polling stations include:
1) general advance polling stations in Finland laid down in a Decree
2) Finnish diplomatic missions set out by a decree
3) hospitals and prisons (institutions)
4) Finnish ships
5) a voter's residence (subject to certain preconditions)
6) Postal voting (Persons living or staying abroad during the entire advance voting period and on election day may vote by post from abroad in general elections)

Advance votesExternal link
The valid and invalid ballots taken into account in the advance voting.
As a rule, advance votes are counted on the actual election day, Sunday, at 15.00 pm. The count may be advanced in large electoral districts; the earliest possible starting time is at 12 noon. The objective is to finish the counting of advance votes by 20.00 pm, from which time onwards advance data can be released.

Advance votingExternal link
Advance voting is conducted in all general elections both in Finland and abroad. The Election Act (section 46, subsection 1) decrees that every enfranchised person is entitled to vote in advance in the general advance voting polling stations in Finland and in the Finnish diplomatic missions abroad. On election day an enfranchised person may vote only in the polling station of his/her own voting district. A voter need not give grounds for advance voting, but may freely choose between voting in advance or voting on the election day.
Advance voting commences on the 11th and ends on the 8th day before the election day both in Finland and abroad.
Advance voting commences on the 11th and ends on the 8th day before the election day both in Finland and abroad.
Advance voting percentageExternal link
The percentage of voters who voted in advance = their share of all voters.
In Statistics Finland statistics the share is calculated from all persons who voted. On the Ministry of Justice's Internet pages the percentage is calculated from all persons entitled to vote.

Comparative indexExternal link
Parliamentary elections, European Parliamentary elections, municipal elections and county elections: The order of candidates belonging to a party that is not in an electoral alliance or to a joint electoral list is determined by the number of votes cast for them personally. The candidates are assigned a comparative index. For the first candidate on a party list or a joint electoral list the comparative index is the total number of votes cast for the party or joint electoral list, the second candidate's comparative index is one-half of that and the third candidate's one-third etc. The comparative indices of the candidates from parties belonging to an electoral alliance are based on the total number of votes cast for the electoral alliance. The comparative index of a candidate not belonging to a joint electoral list is the total number of votes cast for him/her personally.
ConstituencyExternal link
The division into constituencies refers to the regional division of seats to be filled in the election.
County elections:
In county elections the constituency is the wellbeing services county.
Parliamentary elections:
For the purpose of parliamentary elections, the country has been divided into constituencies on the basis of regions. In parliamentary elections the seats in parliament are allocated to constituencies according to a Government decision. According to law, one representative is elected from the Ahvenanmaa constituency and the remaining 199 seats are allocated proportionally to the other constituencies according to their population of Finnish citizens.
Other elections:
The whole country is one single constituency in Presidential elections and in the European Parliamentary elections. Municipalities are the constituencies of municipal elections. Therefore, when counting the votes in these elections, seats are not allocated to different regions. All statistics do, however, present results also by constituency in order to maintain the comparability of different elections.

Constituency associationExternal link
The basic unit (in addition to political parties) for nominating candidates in parliamentary elections, European Parliamentary elections, the Presidential election, municipal elections and county elecions. (See nomination of candidates.)
Council (council seats)External link
The number of seats in the council depends on the size of the municipality (population). The smallest number of councillors is 17 (maximum population 2,000) and the highest 85 (population of over 400,000).
Councillor (elected)External link
A candidate in his/her home municipality who has been elected from among the municipal election candidates on the basis of the votes cast.
Election ActExternal link
The new comprehensive Election Act was approved in the Presidential Session of 2 October 1998. The Act contains both the common procedural provisions on different elections and the specific provisions on all general elections. The Act replaced the earlier separate Acts on parliamentary elections, the Presidential Election, municipal elections and the European Parliamentary elections.
The new Election Act was applied for the first time in the Parliamentary elections of 1999. The new division into constituencies based on the division into regions was applied for the first time in the Parliamentary elections held in spring 2003.
In all elections related concepts the date of ratification is considered to be the first day of being in force. After its entry into force, the new Act has been applied to all general elections.

Municipal electionsExternal link
Finland is divided into local authorities where the autonomy of residents is safeguarded in the constitution. In general elections, the residents elect a council, which makes binding decisions and forms the organs responsible for preparatory work, enforcement and other administrative functions (municipal executive board and committees).
Elections are held, i.e. the council is elected, every four years on the third Sunday of October. This size of the council varies according to the population of the municipality.

Parties are voluntary associations whose main purpose is to influence the handling of the affairs of the state. Membership is usually gained through the party's local association.
Proportional electionsExternal link
In proportional elections each party (or other group) gains representative seats in relation to the number of votes cast for it compared with the votes cast for other groups. If, for instance, a party gains 20 per cent of the votes cast, it should also gain 20 per cent of the available seats.
Presidential elections are not proportional, as the votes are cast for individual candidates and not for parties.

Voting turnoutExternal link
Voting percentage = proportion of voters of persons entitled to vote.
Statistics on general elections include four different voting percentages:
1) the voting percentage of Finnish citizens resident in Finland
2) the voting percentage of Finnish citizens resident abroad
3) the total voting percentage which includes both of the above
4) a separate percentage for persons belonging to group 2 above and living in Sweden.
In European Parliamentary elections a voting percentage is calculated also for citizens of other EU Member States.
In municipal elections the right to vote is not based on Finnish citizenship, but on municipality of residence (See Entitled to vote).
In municipal elections voting percentages by nationality of foreign voters are presented in addition to the total voting percentage: EU Member State, Iceland and Norway, Other country. (See also Advance voting percentage).
The right to vote in county elections is determined in the same way as in municipal elections, their municipality of residence is a municipality belonging to the wellbeing services county.

Accuracy, reliability and timeliness
Overall accuracy
The main possible sources of error in the statistics are errors in the source data or errors in the processing of the data.
Timeliness
In terms of preliminary data, the delay between the event described by the data and the availability of the data is one to two days. The time lag between final, confirmed data and the availability of data is usually less than one week.
The time lag between the data released on the candidates and the availability of data is usually around two weeks, the time lag between the background data published on voting turnout and the availability of data is usually two to four weeks, and it takes several weeks to a few months to complete the data on sex.
Considering the exceptional nature of the statistics not only in terms of the phenomenon they describe but also in terms of the time dependency of the phenomenon, such as the external factors affecting the mid-week holidays of the year in question may have an effect on the delay between the availability of data and the phenomenon.

Punctuality
As regards the Municipal elections 2025, the data were produced and published within the planned timetable.
Comparability
Comparability - geographical
Different areas within the country are comparable so that the legislation affecting the phenomenon is uniform.
The statistics are comparable between different countries to such extent that at the general level the statistics describe the selection of representatives related to the country's regional democracy. The practices, structures and legislation of different countries differ considerably in this respect, which affects the comparability of the data.

The practices, structures and legislation of different countries differ considerably in this respect, which affects the comparability of the data.
Comparability - over time
In principle, the statistics are comparable for the entire time series (starting from 1921). At conceptual level, matters related to the selection of candidates, support for the parties, voting turnout, and other key factors have not essentially changed.
In practice, several changes have taken place in the legislation in the time series (1921 to 2025) (e.g. changes related to voting rights and mergers and abolishment of municipalities), which may limit the comparability of data.

Coherence - cross domain
There are no other statistics relating to the matter and no other statistics are produced on it.
Source data and data collections
Source data
The data set is based on administrative sources.
Data collection
The data derive from different registers. The main source of the data is the Ministry of Justice and the Legal Register Centre operating under it. The voting register is received through the Ministry of Justice, its original source being the Digital and Population Data Services Agency.
There are well-established practices for delivering the data to Statistics Finland between the Ministry of Justice, the Legal Register Centre and TietoEVRY, which is responsible for the technical implementation of the election information system. The details of data delivery are always agreed on in connection with each election.
The data are delivered to Statistics Finland as line transfer.

Frequency of data collection
Basic data are collected in connection with the municipal elections, that is, in the normal cycle at intervals of four years.
Methods
Data compilation
In the statistics the data are processed by summing up, statistics on the phenomenon described in the statistics do not require editing or imputation, for example.
Data validation
The data are validated in the production process by comparing the data published by other data producers and by examining the internal logic of the data.

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 legislationExternal link
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.
Further information: Data protection | Statistics Finland (stat.fi)External link
Confidentiality - data treatment
Data are protected in the statistics for voting districts where the number of persons entitled to vote/who voted is below the threshold set. In the case of such voting districts, persons entitled to vote/who voted in the area in question are presented in connection with another voting district in the same municipality.
Release policy
Statistics Finland publishes new statistical data at 8 am on weekdays in its web service. The release times of statistics are given in advance in the release calendar available in the web service. The data are public after they have been updated in the web service.
Further information: Publication principles for statistics at Statistics FinlandExternal link
Data sharing
The data are not shared between other statistical offices or units.
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.
Quality assessment
The quality of the statistics on municipal elections is assessed continuously in connection with the production of the statistics. The produced data are compared with the data produced by other data producers and the materials and the produced data are controlled for logic.
Quality assurance
Quality management requires comprehensive guidance of activities. The quality management framework of the field of statistics is the European Statistics Code of Practice (CoP). The quality criteria of Official Statistics of Finland are also compatible with the European Statistics Code of Practice.
Further information: Quality management | Statistics Finland (stat.fi)External link
User access
Data are released to all users at the same time.
