Specific Approaches to the Methodology of the Industrial Production Index Calculation at County Level

Industrial production index is an extremely important statistical indicator, which should reflect as faithfully as possible the actual variations of the industrial production volume evolution, both at the national level and in each self-governing territorial unit.Considering the high number of mainly theoretical approaches to the study of these methodologically complex issues, this paper aims at describing the theoretical aspects in a logically structured manner, while referring in a consistent manner to the main practical steps that need to be taken. The final goal is to disseminate statistical indicators that satisfy the information needs of all categories of beneficiaries. At the same time, one should also bear in mind that the statistical information about the short-term evolution of this industrial indicator must be provided in a consistent manner for all the European Union member states. In our paper, special emphasis is laid on ensuring an adequate sample representativeness level, both from the viewpoint of the number, structure and value of the industrial products composing it, seen through the eyes of families (CAEN Rev. 2 and PROD1), and from the viewpoint of the reporting businesses, mainly as concerns their turnover percentage in the self-governing territorial unit under consideration, in the year used as reference reporting year.
