The sampling method is a stratified plan by the nomenclature Nace rev 2, workforce
bands, and region.
Allocations are optimised on the Nomenclature x workforce bands, and on energy consumption,
taking into account the average dispersion per stratum over the last 3 years. The
allowances are exhaustive above the threshold of 250 employees, big consumers of energy
and for strata of less than 10 units.
Sample size
The sample includes approximately 8 500 establishments.
