The compilation is consistent over time and comparable to similar compilations for other countries.
Comparability - geographical
The International Ship Register, IHS, compiles statistics on all ships over 100 GT. The information is primarily based on national ship registers and is thus comparable to the statistics compiled by Statistics Denmark.
Comparability over time
For the overall calculations, the statistics are comparable to those of previous years. Before 1993, the Faroese fleet was included in the statistics, as well as approximately 90 ships just below 20 GT.
Coherence - cross domain
The Danish Shipowners' Association publishes detailed statistics on Danish registered, Danish owned, and Danish operated ships, based on part of the International Ship Register (IHS), the Association's own data, and the Danish ship registers at the Maritime Authority. The information on Danish registered ships is practically comparable to the statistics compiled by Statistics Denmark. Minor discrepancies may occur due to differences in reporting periods.
Coherence - internal
There is a high degree of consistency between the sources, as all entities in the Shipowners' Association's compilation can be found in the ship registers.
