Information about revisions to the Volume Index of Industrial Output

Final index for 2012

The data on the Volume Index of Industrial Output for the year 2012 are final. The final annual volume index is based on the regional and industrial statistics on manufacturing. In order to calculate the final annual changes, the changes in gross value at the 3-digit level of the industrial classification have been divided by changes in the producer price index of the industries concerned. The preliminary annual change of the monthly index has been revised with the obtained coefficient. Calculation of the final annual volume index influences the index point figures and change percentages for 2012.

Below is a table showing annual changes of the preliminary monthly index and the final annual index by industry.

Revisions affecting calculation in 2014

Industry-specific weights for value added and gross value weights for each stratum have also been changed to correspond to the situation in 2012. The value added share of mining and quarrying decreased in 2012 compared with 2011. The value added share of the electrical and electronics industry decreased from 2011. The value added share of the food industry grew by nearly one percentage point compared with 2011.

The table below shows the industry-specific shares for value added of the value added of total industries (BCDE) in 2010, 2011 and 2012.

Table 2. Value added shares in industry in 2010, 2011 and 2012

TOL 2008 Value added share 2010 (%) Value added share 2011 (%) Value added share 2012 (%)
Total industries (BCDE) 100.0 100.0 100.0
Mining and quarrying (B) 1.7 3.8 2.0
Manufacturing (C) 83.7 82.9 83.9
Food industry (10-11) 7.8 7.5 8.4
Forest industry (16-17) 13.6 13.1 13.3
Chemical industry (19-22) 13.1 13.1 13.7
Metal industry (24-30, 33) 41.4 40.8 39.5
Electrical and electronics industry (26-27) 13.4 10.2 8.5
Manufacture of motor vehicles (29-30) 2.0 2.6 2.8
Electricity, gas, steam and air conditioning supply (D) 12.0 10.2 10.7

Seasonal adjustment models updated

The seasonal adjustment models for the Volume Index of Industrial Output are updated once a year. The updating of the models has effects on the industry-specific working day and seasonally adjusted series and trend series.
