Mass media statistics: documentation of statistics
Basic data of the statistics
The statistics describe mass media from several different perspectives, including the economy, enterprise structures, imports and exports, labour force, contents as well as supply, use and consumption.
The data describe the whole of Finland. The statistics do not include regional reviews.
The statistics also include international reference data.
The mass media statistics are based on a number of different sources. A majority of the primary sources are statistics, surveys and other data produced by external parties (including trade associations in the media sector and market research institutions). Some of the sources are surveys and other data of Statistics Finland (including the Business Register, Household Budget Survey, international trade statistics, Time Use Survey and Leisure Survey). No separate data collection has been carried out for the purpose of the statistics.
The statistics have been compiled for the use of many different operators, such as administration, researchers, businesses, educational institutions in the field, organisations and mass media.
Calculations estimating the size of the media market are released in connection to the statistics’ annual release. Other data are released in the regularly updated Mass media statistics’ table service on the website of Statistics Finland. The table service is available in Finnish and English.
The data content of the mass media statistics is assessed and renewed on a continuous basis.
Unit of measure
The primary source data are primarily released elsewhere. However, external parties produce some of the data from their own registers upon request.
A significant portion of the tables on the mass media statistics have undergone further processing.
Frequency of dissemination
Accuracy, reliability and timeliness
Any possible errors are corrected and the users are informed about them as quickly as possible. Statistics Finland informs about significant errors to the same extent and through the same channels as in the releasing of the original data.
Notations about corrections and their points of time are added to the corrected releases. If possible, the original, erroneous data are also left visible.
Typographical and other form errors in statistics are corrected as fast and flexibly as possible and no separate notifications are made of them on the web pages.
Information about changes made to statistical databases is posted on the ‘Revisions in the database’ page. Only the latest data are updated in databases.
Deviations from timetables are also regarded as errors. If the release of statistical data is significantly delayed from the announced point of time, information about the delay is posted on Statistics Finland’s home page.

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.

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
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.

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 management requires comprehensive guidance of activities. The quality management framework of the field of statistics is the European Statistics Code of Practice (CoP). The frameworks complement each other. The quality criteria of Official Statistics of Finland are also compatible with the European Statistics Code of Practice.

Data are released to all users at the same time. Statistical data may only be handled at Statistics Finland and information on them may be given before release only by persons involved in the production of the statistics concerned or who need the data of the statistics concerned in their own work before the data are published.
