Documentation on methodology
The observed and surveyed unit is the establishment because it is the closest to the expense and better located unit.
Since the observation year 2009, the survey is conducted by internet (a paper questionnaire can be sent on request). More than 80% of the surveyed establishments do respond. In 2019, response rate was lower due to Covid crisis (74 %).
