Methodological explanation for the news release:
Industrial production volume indices
Calculation method
The industrial production index, in accordance with the National Classification of Activities, is calculated in two steps: in the first step the indices are calculated by weighting the individual indices of quantity data of industrial products, and in the second step by weighting with adequate weights for different activity levels (groups, divisions, sections and total).
The monthly industrial production index is calculated by the Laspeyres formula and is used for calculation of other indices.
Weighting coefficients for the products from the Nomenclature of industrial products, used for the calculation of the industrial production index, is calculated based on the share of the production values of those products in the “"Annual Report of Industry"" and Value Added (the last weighting coefficients are calculated from the ""Annual report for industry"" IND.21 for 2022 and the value added in industry in 2022). The structure of industrial activities (structure by divisions) is calculated based on the value added for 2022 and is reviewed at the beginning of each year for the calculation of indices for the current year.
The structure of industrial activities (division structure) was calculated on the basis of the value added for 2022 and is updated at the beginning of every year for the calculation of indices for the current year.
Classifications
Classifications used for collecting data in the Monthly Report on Industrial Production and for publishing results are: the National Classification of Activities Rev.2 (Official Gazette No. 147/2008) and the National Nomenclature of Industrial Products (Official Gazette No. 136/2018).
Recommendations
The industrial production index is based on EUROSTAT’s recommendations in the Methodology of Short-Term Business Statistics from 2021 and is harmonized with Commission Implementing Regulation (EU) 2020/1197 of 30 July 2020 laying down technical specifications and arrangements pursuant to Regulation (EU) 2019/2152 of the European Parliament and of the Council on European business statistics repealing 10 legal acts in the field of business statistics.
