Statistical processing

Source data

Activity, association and membership information is based on an extract from the Central Association Register, drived by the The Sports Confederation of Denmark, DGI and the Danish federation of Company Sports. See [dif.dk/medlemstal](https://www.dif.dk/en/politik / we-are / memberships) for the overall association sport and dif.dk/forbund for detailed numbers for each federation.

Results from the Sports Research Institute's studies of the population's sport habits are received in the form of special data delivers.

Individuals' use of sport activities within the past three months by sport activity and age and sex (IDRKVU01) is based on the Cultural Habits Study, which is why reference is made to its source documentation. https://www.dst.dk/da/Statistik/dokumentation/statistikdokumentation/kulturvaneundersoegelsen/statistisk-behandling

Memberships of sports organizations (share of population) by region, sex, age and time (IDRAKT02) is constructed from IDRAKT01 and FOLK1A, why reference is made to the documentation of these two tables. Population are extracted from FOLK1A in the fourth quarter of the relevant year.

The attendances statistics are based on several data prepared by the federations within the individual sports. Some data are collected by Statistics Denmark at the individual federations.

Attendance numbers and number of home matches for national team statistics in football are registered in (Dansk Boldspil Union database) [https://www.dbu.dk/landshold/landsholdsdatabasen/landsholdsdatabasen.aspx]

The reports to the attendances statistics include the total number of matches and attendances for the individual sports by league and gender.

The medal statistics are based on the The Sports Confederation of Denmark's medal overview, which has been prepared on the basis of reports from approx. 60 special federations. More detailed information about activities, disciplines, tournaments and medalists can be found at https://www.dif.dk/idraetten-i-tal/medaljestatistik. Data regarding the Danish medals are reported to DIF from the special federations, where the requirement is, that there must be four participating countries in an official championship as a minimum. The Federation of Danish Sports search for duplicates in the reports. The medal statistics does not include junior and veteran medals. The statistics include 'European Games', which was held the first time in 2015, and corresponds to a kind of "Continental Olympic Games".

The rank tables IDRRES01, IDRRES02 are IDRRANG1 are based on special extracts from a relative medal table comparing international sports performance established by Gracenote - A Nielsen Company. The population numbers of the countries taken from the UN website.

Frequency of data collection

Yearly, however, results regarding the population's sports and exercise habits are made every four years.

Data collection

Data for the members' activities of the sports associations and the medal overview are sent as special features from the Sports Confederation of Denmark. Selected results from IDAN's studies of the population's sports and exercise habits are received in the form of special extracts. Data for the attendances is collected from the federations or by registering data from the websites of those organizations. Data about medals and rang are collected by special extracts from DIF and Gracenote. These are ranked and from this validated by comparison with previous years.

Data validation

Data regarding sports associations' members and medals are validated by comparison with previous years' results. In case of larger fluctuations, the data provider is contacted for confirmation and, if necessary, correction of errors. Results from IDAN's studies of the population's sports and exercise habits are compared to the published results. The attendance numbers are checked by comparing with the attendance figures for the previous years. Account is also taken of restructuring of league structures where fewer / more matches and thus fewer / more attendances may occur. Data about medals and rang are checked by comparing medals and sporting events the year in question and in previous years.

Data compilation

The data process includes coding, tabulation, checking and debugging of detailed register extracts to the level of publication as well as validation of results in comparison with the results of previous years.

The statbank table IDRKVU01 is based on the Cultural Habits Survey, which is why reference is made to its data processing documentation. https://www.dst.dk/da/Statistik/dokumentation/statistikdokumentation/kulturvaneundersoegelsen/statistisk-behandling

The processing of the data includes coding, tableing and checking of detailed registry extractions to the level of publication as well as validation of results compared to the previous year's results.

Summing up the municipalities in The statbank table IDRFOR01 doesnt give "All Denmark". This is because associations / memberships outside the municipalities are not included in any specific municipality, but only in "All Denmark" (Whole Country).

For the attendances statistics, specifically, play-off matches between clubs for promotion, relegation and qualification in handball and football are not included in the total number of matches and attendances. This is because the clubs in these cases represent different leagues or qualify for another league.

In the attendance statistics, "matches" is considered as home games played in Denmark. The away games for the national teams are therefore not included in the statistics.

The statbank tables IDRRES01, IDRRES02 and IDRRANG1 compare the Danish results internationally with the other athlete nations over a given year, based on the official Olympic disciplines for the upcoming Olympics. The disciplines in these tables will change every four year, depending on which ones are added and subtracted. The Olympic-disciplines, which are in the program during the Summer- and Winter-Olympics, is a measure Team Denmark (TD) and the Danish Sports Federation (DIF) normally use, when studying Denmark's performance internationally.

The disciplines of the summer- and winter-Olympics typically change at a new Olympic. Information regarding the relevant disciplines a specific year, refer to the official Olympics website https://www.olympic.org/sports

When it is not an Olympic year, the results from the World Championships in the Olympic-disciplines are used instead. In disciplines where there is no World Championship,results from the World Cup will be used instead. In other cases, results are included from the latest World Championship in the specific discipline. The results are processed, so that the number of medals and the number of participants per nation is similar to the one at the Olympics.

Performance are calculated in gold medals, podium (number of medals) and based on the top-8 places within a discipline (tTp-8). The Top-8 provides and larger database, hereby securing a more robust goal when nations performances between are compared. This is necessary with smaller nations winning a limited amount of medals at the Olympics or World Championship.

If a team or athlete does not represent a nation, the medal in the statistics will be considered undisclosed. This can e.g. be independent Olympic athletes.

Members and population of Christiansø are summed with Bornholm in IDRAKT01 and IDRAKT02.

From 2022, it has been possible to report a gender identity other than male and female under a new category 'other' to the Central Register of memberships, which is the basis for these statistics. The information is based on the members' own reporting in the association's membership system. There may be uncertainty about what the category 'other' covers in the report, as it is not defined in more detail. The number of members in the new gender category will only appear from the table's total. Neither the handling of the new gender category in the data source nor the rounding has any effect on the applicability of the statistics compared with previously.

Membership numbers are listed as unique memberships in sports associations. A person who is a member of two associations will count twice in the statement. Membership numbers in the IDRAKT01 table are lower than in Table IDRFOR01, as non-sporting activities such as theater, politics, etc. are not in IDRAKT01.
