In its current form, the statistics are comparable from 2007 onwards for the National Archives, and from 2011 onwards also for town and local archives. The time series are comparable without data breaks from these years, although only from 2011 for National Archives' electronic records. Older figures for the National Archives are available in the Statistical Yearbook back to 1980. There are no directly comparable international statistics in this area.
Comparability - geographical
No comparison to international sources has been made.
Comparability over time
There are no data breaks in the tables for the National Archives and the time series begins in 2007. However, the electronic holdings are only accounted for since 2011. The time series for town and local archives begins in 2011. Older time series can be found in the Statistical Yearbook.
There may be inconsistency between the changes in collection size between the two years and growth in the form of accessed records for the same period. This may be due to the remediation of the archives and discarding of material (if deviation is negative) or result from delays in the processing of incoming material (if deviation is positive).
From 2014, data on size of holdings, accessed records and written enquiries are not specified by individual national archives but are presented in aggregate under the National Archive in Copenhagen. Also from 2014, the Provincial Archives, Danish Business Archive and Danish Data Archive have changed their names to National Archives.
The statbank table ARKIV02B replaces the table ARKIV02 from 2019. This is due to a new model for imputing values into the statistics.
In the reference year 2023, the delivery of archives has been postponed at some larger archives, which is why "increase of archives / Received archives (shelf meter)" has decreased compared to 2022. The fluctuation is expected to be balanced with the publication of the reference period 2024, which is published during august.
