The source states: "It should be noted that the classification of an individual in one or the other of the professional categories is carried out for each film. Thus, the same individual can be counted several times, since he occupies jobs of different categories on several films. On the other hand, it is counted only once in total employment. It follows from this method of calculation that the sum of the numbers by category of employment is not necessarily equal to the total workforce. "
