Définition
Unemployed persons for the purposes of the population census are persons (aged 15 or over) who declared themselves to be unemployed (either registered or not with Pôle Emploi) unless they have also explicitly declared that they were not looking for work ; and on the other hand the persons (of 15 or more years old) who declared themselves spontaneously neither in employment, nor unemployed, but who nevertheless declared to look for an employment.
Remarque
An unemployed person (population census) is not necessarily an unemployed person in the sense of ILO.
