collected in 2019, via an online questionnaire proposed by the internet-based data
collection system developped by Insee.
The annual data on the year N is collected in several waves between February and June

Above given size thresholds (thresholds on tunover and on number of employees), which are variable according to the economic sector, the strata are take-all strata.
