Data collection

The survey is historically conducted by mail. It is possible to respond by internet since 2013, via a fillable PDF questionnaire. The internet data collection mode is expected to grow in the future, with the forthcoming integration of the survey in Coltrane, the internet-based data collection system currently developped by Insee.

The annual data on the year N is collected in several waves between February and June of the year N+1  in order to take account of businesses' different financial year end dates.

Sampling method

The sampling design is a two-stage stratified clustered simple ramdom sampling, according to strata defined by the size classes crossed with the economic sectors. 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.

120 000 legal units (principaly) and enterprises

Data collection documents

As the scope of the survey in terms of sector is very wide (see § on sector coverage), there are different models of questionnaires, adapted to the different main sectors covered by the survey.

Data validation

The data and resultats are checked and validated by the ESANE teams in Nantes and Paris.

Data compilation

A specific data editing procedure has been implemented. This procedure  also ensures the consistency of the survey data with admistrative data.
