Comparability

Comparability - geographical

No known statistics on trade in IPR exists.

Comparability over time

The statistics are calculated for the so-called Resource areas, which are coherent business areas. The resource area definition is based on the Danish Activity classification, Dansk Branchekode 2007 (DB07. For 2008 the statistics can also be calculated on basis of DB03.

Renewal of reference period: With the objectives of reducing the response burden and at the same time obtain higher precision in the calculations, it has been decided that from the reference year 2009 and onwards only information on trade during the last calendar year will be collected. The 2008-statistics are therefore a transition year for which information on trade in IPR is asked both for 2003-2007 and for 2008.

In conclusion, the comparability are high from 2008 an onwards.
