Accuracy and reliability

Overall accuracy

Information about the economic environment is characterized by a degree of uncertainty, since not all theaters are able to distribute income on a seasonal basis; Instead, information on financial / calendar year. This means that the statistics do not always have consistent information about the performances, which are always based on seasonal inventories and economic sizes.

In connection with touring theaters is not always possible to quantify the number of spectators precisely; When this is the case used estimates, for example, can be based on the maximum number of audience in sales contracts, etc.

Reporting for the Performing Arts statistic is voluntary. Therefore, choosing some theaters not to report. All large and medium state-subsidized and non-subsidized theaters, participate in the study and all the theaters with fixed scene also participate in all seasons.

Sampling error

No sampling error has been calculated for this statistics. As regards the large and medium-sized state-funded theaters, the response rate is close to 100%. Since these categories of theaters cover the vast majority of activity in the sector, the sampling error is considered to be limited.

Non-sampling error

Until the 2008/2009 season, the statistics were called "Theatre Statistics". At that time, only theatres and producers of theatre performances were asked about their activities. This meant that the genres included in the statistics were only covered if they were produced by the theatres or producers that were part of the population. For example, the genre "revue/cabaret" only included revues and cabarets from the theatres and producers that participated, meaning that genres such as revue and circus are not fully represented in the statistics. In the 2015/2016 season, a new genre classification was introduced, and from the 2020/2021 season onwards, an expanded version of this genre classification has been applied.

The statistics have precise coverage for state-subsidized theatres, as information is provided annually by the Danish Agency for Culture. Coverage for non-state-subsidized theatres is based on other sources, such as the Terebas database (since the 2017/2018 season) and reporting history. In connection with the 2018/2019 season, the Terebas database was cross-referenced with the Business Register. There are no duplicates in the population, as theaters and producers are assigned unique IDs. Measurement errors may occur, for example, due to rounding, co-productions, or estimates of audience numbers. Only theaters with reported activity are included in the statistics.

Quality management

Statistics Denmark follows the recommendations on organisation and management of quality given in the Code of Practice for European Statistics (CoP) and the implementation guidelines given in the Quality Assurance Framework of the European Statistical System (QAF). A Working Group on Quality and a central quality assurance function have been established to continuously carry through control of products and processes.

Quality assurance

Statistics Denmark follows the principles in the Code of Practice for European Statistics (CoP) and uses the Quality Assurance Framework of the European Statistical System (QAF) for the implementation of the principles. This involves continuous decentralized and central control of products and processes based on documentation following international standards. The central quality assurance function reports to the Working Group on Quality. Reports include suggestions for improvement that are assessed, decided and subsequently implemented.

Quality assessment

Not all theaters are able to distribute income on a seasonal basis and instead gives information on financial / calendar year. That means that there not always are compliance between goals based on seasonal inventories and economic sizes.

In connection with touring theaters it is not always possible to quantify the number of spectators precisely; When this is the case estimates are used. Reporting for the performing arts statistic is voluntary. Therefore, the statistics are not fully comprehensive. Several of the non-state-subsidized theaters report that they do not have resources to cooperate in the investigation. Furthermore, performing arts statistics comprises a lot of small theater producers / project theaters that receive government subsidies to develop a single production for whom it's hard to do the reporting. Yet it is estimated that performing arts statistics cover the majority of activities in performing arts, as all large and medium state-subsidized and non-subsidized theaters, participate in the study.

Data revision - policy

Statistics Denmark revises published figures in accordance with the Revision Policy for Statistics Denmark. The common procedures and principles of the Revision Policy are for some statistics supplemented by a specific revision practice.
