The statistics contain data on the Danish archives' conventional collections' size and the accession of records, number of visitors in the reading rooms and number of queries via letters or email. Additionally, manpower is listed by the number of full-time employees, distributed by regular employees, voluntary employees and subsidized employees. For the national archives, the electronic collections' size and homepage visits are also included.

Data description

An archive collects, registers and preserves archive material such as documents, photographs, films, maps etc. from a defined local area such as one or more parishes, a city or an entire municipality. The statistic contain information about the activities in the archives. For example, there is information about the size of the collections, archives received, visitors, employees, etc. The statistics illuminate the activity at the state archives, the member archives of the Organization of Danish Archives (ODA) and the City and Local Archives (SLA) and a few larger archives.

There may be a discrepancy between changes in the size of the collection and the growth in the form of received archives. This may be due to cleaning up the archives. Fluctuations may occur in the number of guests for a region, for example, if an archive has not been active for a period due to relocation, restructuring or the like.
