The statistics has been compiled since 2001. Before the survey year 2004 the sector Business and management consultancy activities has been studied with Accounting, bookkeeping and auditing activities. It can be problems in comparing figures over time. The questionnaire, the sample design and the calculation method have been adjusted a few time, latest in 2013, where data for 2012 has been backcasted using new method.
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
It can be problems in comparing figures over time. The survey was conducted for the first time in 2001. For the reference year 2006 the questionnaire has been changed in accordance with the Eurostat questionnaire. In the reference year 2008 the sample changes from consisting all enterprises with or over 10 employees to consisting of all enterprises with 20 or more employees, a part of enterprises with 5-19 employees and no enterprises with 1-4 employees.
From the reference year 2013 the method is changed so the enumeration is based on a new data from the Central Business Register. Data are back calculated for 2012. Which means that the results before the year 2012 are not directly comparable to the results from 2012 onwards.
In Statistics Bank the data can be found back to 2001. Due to the differences in methods and units the data for the earlier years can't be expected to compare with the current data beginning with year 2012.
Coherence - cross domain
At national level the data for the survey are grossed up to the provisional turnover from the statistic Purchases and sales by enterprises. The final turnover is not available at the time when data are grossed up. The Purchases and sales by enterprises statistics provides the total turnover in the sector for Legal Activities, whereas the survey in addition to the total turnover also indicates the breakdown of the turnover by different services.
At European level the data for the statistics are grossed up to the level for the Danish Accounts Statistics. As in the Purchases and sales by enterprises statistics the breakdown of the turnover by various services doesn't exist in the accounts statistics but only in this survey.
Coherence - internal
