Industrial production - January 2025

The industrial production indices are calculated using the chaining method introduced starting from the publication of the data relating to the month of January 2022. From January 2025, the calculation base is set to the year 2024, while the reference base, in line with the other short term indicators, remains the year 2021. Indices are produced according to Ateco 2007 classification (Italian edition of Nace Rev. 2). The purpose of this review and any resulting updates is to guarantee that the indices remain robust and to adapt them to economic or technical developments, in particular by including the monitoring of new products and by eliminating those whose production has become irrelevant. Furthermore for the branches monitored in working hours, productivity coefficients have been revised. Finally, the seasonal and working day adjustment (SA-WDA) models have also been revised over the recent past to improve the quality of the indices. The methodological aspects connected to the update of the 2024 calculation base are illustrated in the Information Note released together with this flash statistic.

In January 2025 the seasonally adjusted industrial production index increased by 3.2% compared with the previous month. The change of the average of the last three months with respect to the previous three months was unchanged.

The calendar adjusted industrial production index decreased by 0.6% compared with January 2024 (calendar working days being 21 versus 22 days in January 2024).

The unadjusted industrial production index decreased by 3.6% compared with January 2024.
