Comparability

Comparability - geographical

To Eurostat the data are provided only for enterprises with less 20 person employed (according to EU's regulation). In the Statistics Database of Eurostat the distributions of the turnover by services and residence of client are published on EUROSTAT's homepage. It is considered that there are good comparability across countries, because the statistics should be produced by common guidelines and principles.

Comparability over time

The statistics is comparable from 2023 and onwards, where it only covers enterprises with at least 20 employees. The questionnaire used for the current timeseries is directly comparable to the one used between 2012 and 2022.
The survey was conducted for the first time in 2001. Between 2004 and 2005 changes were made to the classification of products by activity (CPA) thus the two years are not comparable. The years 2005 and 2007 are not comparable because of a shift to NACE Rev. 2 activity classification. The years 2007 and 2009 are not directly comparable because of changes in the products in the questionnaire to the EC-questionnaire. From the reference year 2013 the method is changed so the enumeration is based on a new data from the Central Business Register. That means the results before the year 2013 are not directly comparable to the results from 2013 onwards.

In Statistics Bank the data can be found back to 2004. Due to the differences in methods and units the data for the earlier years can't be expected to compare with the previous data beginning with the year 2013, nor with the current data beginning with year 2023.

Coherence - cross domain

At national level the data for the survey are grossed up to the provisional turnover from the Accounts Statistics for Non-Agricultural Private Sector. At European level the data for the statistics are grossed up to the level for the final version of the Danish Accounts Statistics for Non-Agricultural Private Sector.

Coherence - internal
