Source data

The data needed to calculate this index is collected from:

  • the Nominative Social Declarations (DSN) data for the wage bill and the hourly volume of work, since the first quarter of 2020;

  • the short-term data of the URSSAF Caisse nationale, relating to social charge exemptions;

  • the labour cost component of the Labour Cost Survey (LCS) to measure certain costs associated with the employment of employees, over and above wages and employer contributions (e.g. payroll tax).

Before 2020,
- the hourly volume of work is calculated from the quarterly surveys on labour activity and employment conditions (ACEMO) conducted by DARES (statistical service of the Ministry of Labour). The (paid) hours measured in the DSN better reflect variations in the volume of work than those previously obtained from the ACEMO surveys, which only recorded collective working hours and excluded individual variations such as overtime or partial activity ;
- the wage bill is calculated from URSSAF Caisse nationale data.
