Activity and turnover indices calculation answer to a national and a European imperative. They are used to measure the monthly changes in sales of companies in the sectors concerned. As such, they are a primary information to monitor the business cycle in France. Turnover indices fall under the European regulation on short-terms statistics -- the Regulation (EU) 2019/2152 of the European Parliament and of the Council on European business statistics (EBS-Regulation).

The turnover indices are calculated by INSEE from a tax source, the CA3 form (, which companies fill in every month for the payment of VAT.
