Three-month change: decrease within the industry for food products

According to In order to facilitate the interpretation of the short-term development, the index of production publishes three-month moving averages of the seasonally-adjusted figures. We normally compare the latest non-overlapping three-month periods. Seasonally-adjusted monthly changes must be interpreted with caution., manufacturing output had a decrease of 0.3 per cent in the fourth quarter of 2022 compared to the previous quarter. The industry for food products contributed the most to overall output with a decrease of 1.8 per cent.
