This information is recorded in the Sirene (Computer system for the business and establishment register) administrative directory.

The Sirus statistical register is the statistical complement to the Sirene administrative register. It includes statistical information, particularly of an economic nature, relating to businesses and their establishments.

The Business Demography Information System (SIDE) draws on these two registers to provide information useful for monitoring the active population of businesses, legal units and establishments.

This source of information - the Business Demography Information System (SIDE) - is used for the creation of business birth series.

The main aggregates are reviewed and validated during the preparation of the Informations Rapides publication.

Business creations are based on an exhaustive count.

The series are adjusted for seasonal and working-day variations.

To be able to compare the number of births between different months, the number of business births in each month is adjusted for seasonal variations (SA) and working days (WDA), via the X13-Arima procedure.

Business birth series (excluding microentrepreneurs and micro-entrepreneurs registration series) are seasonally adjusted independently, for each sector. The SA-WDA “total” series is the sum of SA-WDA sectoral series.
