Comparability

Comparability - geographical

The statistics are not based on EU legislation or other international guidelines, but other countries collect and publish similar data. For example, the Norwegian Sports Confederation collects and publishes figures for sports associations, memberships and activities on their website and in [key figures reports](https://www.idrettsforbundet.no/contentassets/9f94ba79767846d9a67d1a56f405okk20194c2. pdf). In Sweden, the Swedish Research Council for Sport Science runs a website on sports statistics, which i.a. shows membership and association figures based on reports from special unions. In the Netherlands, the National Bureau of Statistics periodically publishes survey data on sports associations, memberships, volunteers and use of facilities

Comparability over time

These statistics are comparable through the entire published period.

There are some discrepancies in the membership for 2019 compared to 2018, which relates to the table IDRFOR01. This is due to the fact that it is the local business sports associations that register how many people exercise at work in their local areas. It is a practice that is underway, with some of the local corporate sports associations registering exercise at the workplace to a greater extent than before. This applies, for example, in the municipality of Lemvig. In addition, the relocation of members between municipalities can be a cause of large member fluctuations, which is the case for Brønderslev and Albertslund in 2019. This is due to the fact that larger national associations during corporate sports are registered under the municipalities where the companies are headquartered.

Coherence - cross domain

Certain results can be compared to other publications from the original sources, such as the Central Association Register, Facility Database and results from the Sports Institute's studies of Danish sports and exercise habits.

Coherence - internal
