New seasonal adjustment software adopted

Starting from the January 2015 data, a new seasonal adjustment software J-Demetra+ will be adopted in the indices of turnover. The software change does not affect the used seasonal adjustment method. The change does not influence the interpretation or use of the time series either. You can read more about the implementation of the new seasonal adjustment software in Statistics Finland's press release.

In connection with the adoption of the new seasonal adjustment software, the seasonal adjustment models of the time series are also updated. Due to the updating of the models, the seasonally adjusted series and the trend series may change. As a rule, changes caused by the updating of the models are minor but in some industries the changes are more clearly visible.
