Monthly

Data collection is by post and via the internet over a period that extends from the end of the month preceding the survey month to the survey publication date, i.e. 4 business days before the end of the current month.

Survey results are sent to the European Commission 4 business days before the end of the month.

The collection period runs from the end of the month preceding the reference month of the survey to the date of publication of the results (between the 20th and 25th of the reference month).

Survey of a sample of 4,500 enterprises in services and road haulage of goods.

All road haulage companies having annual turnover in excess of €30 million are surveyed systematically.

For other service enterprises, this threshold is €45 million.

4,500 units

The survey is conducted every month but not all questions are asked every month. Some questions are only asked to enterprises in road haulage of goods.

In practice, three models of questionnaires were created to take into account these specificities:
- the first questionnaire corresponds to the months of January and July;
- the second one is sent in February, March, April, May, June, August, Septembre, November and December;
- the last one is sent in April and October.
