Flores is built from the "All employees database". The "All employees databases" itself is the result of a synthesis of administrative sources: personal social declarations (DSN), including payroll files specific to the State and declarations specific to individual employers.

Flores is therefore a "secondary" statistical source, derived from a first statistical file and not directly from administrative declarations.

Annual

Geographical and sectoral location information is taken from the Statistical business register (Sirus) and the Business Register Identification System (Sirene) when available, and from the "All employees database" otherwise.

Additional processing is applied to improve the quality of the location (geographical and sectoral) of paid employment.
