Monthly change: decrease within refined petroleum, chemicals and pharmaceuticals

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 an decrease of 0.5 per cent from October to November 2022. The industry grouping refined petroleum, chemicals and pharmaceuticals contributed the most to overall output fall with an decrease in production of 6.1 per cent.

On the other hand, the overall output decrease was dampened by a growth of 2.9 per cent within production of non-ferrous metals.
