Définition
The underlying (or standardised) employment rate is the arithmetic average of the detailed age-specific employment rates. It makes it possible to neutralise the unequal demographic weight of the age groups included in the employment rate.
For example, from the 2000s onwards, the underlying employment rate of older people (50-64 years) makes it possible to measure an employment rate that does not take into account the fact that the baby-boom generations are gradually reaching retirement age and inflate the weight of the inactive age groups among the 50-64 year old.
