Strengthened exploitation of two administrative sources:

- the files of income annual statements of enterprises: Industrial and Commercial Profits System (BIC), Non-Commercial Profits system (BNC) or Agricultural Profits (BA), coming from the DGFiP;

- the annual declarations of social data (DADS).

These two administrative sources are completed by statistical surveys : the annual production survey (EAP) on industry, and the annual sectoral survey (ESA) for other sectors of activity.
