Comparability

Comparability - geographical

The statistics is carried out in collaboration with the EU-commission, and the same survey is carried out in other EU-countries. Please refer to DG ECFIN.

Comparability over time

The Tendency survey in Retail trade was launched in May 2011 by Statistics Denmark. Data is comparable over time with similar tendency survey data up until April 2011 provided by the EC Business and Consumer Surveys programme and managed by Directorate-Generale for Economic and Financial Affairs, DG ECFIN.

As of August 2014 some phrasings in the questionnaire have been revised in order to harmonize fully to the guidelines of DG ECFIN. Previous, questions of this type: "Regarding Sales, how was the development the last 3 month (e.g. May-July) as compared to the previous 3 month (e.g. February-April)? please tick either less; unchanged or bigger". Now there are no comparison between two 3-month periods, and instead is asked: "How has your Sales developed over the past 3 month? please tick either decreased, unchanged or increased" The results are believed to be the same, and no data break has been detected. The same change has been made for questions concerning the future development over the next 3 month. Furthermore the answer possibilities regarding Current volume of stock has been changed from less; unchanged or bigger to too small; adequate or too large. This may have led to break in data.

Coherence - cross domain

Data from the Tendency survey in Retail trade supplements the other short-term statistics relating to this area. Similar surveys are conducted by the other EU member states through the EC Business and Consumer Surveys programme managed by Directorate-Generale for Economic and Financial Affairs (DG ECFIN).

Coherence - internal

The data set of the survey is consistent.
