New seasonal adjustment software adopted

Starting from the January 2015 data, a new seasonal adjustment software J-Demetra+ will be adopted in the Volume Index of Industrial Output. 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.

The final index for 2013 will be released in connection with the February data on 10 April 2015. The gross and added value data for 2013 used in the calculation of the final annual volume index could not be completed by the time of the January release on 10 March 2015.
