Information about revisions to the Volume Index of Industrial Output

Final index for 2009

Statistics Finland has calculated the final index for 2009. The final annual volume index is calculated from the regional and industrial statistics on manufacturing compiled from structural statistics on manufacturing. More detailed description of the statistics is available at 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 2009.

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

TOL 2008 Annual Index 2009, percentage change
Preliminary Final
Total industries (BCDE) -20,9 -18,1
Manufacturing ( C ) -23,3 -20,3
Food industry (10-11) -1,2 -3,3
Forest industry (16-17) -20,3 -19,5
Chemical industry (19-22) -13,4 -9,4
Metal industry (24-30) -30 -25,3
Electrical and electronics industry (26-27) -33,7 -23,1
Metal industry (24-30) excl. (26-27) -27,1 -26,6
Electricity, gas, steam and air conditioning supply (D) -7,4 -0,6


Revisions to January-July 2010

In accordance with the chain index principle, the value added weights of industries have been changed to correspond to the situation in 2009. Establishment-specific weights have also been changed to correspond to the situation in 2009. In addition, the deflators used in industry 26-27, electrical and electronics industry, have been reviewed. These revisions have influenced the point figures and change percentages for the early part of the year.

In Its release on 10 September 2010 Statistics Finland indicated that the growth figure for January to July for total industries (TOL BCDE) would be 8.2 per cent. The final data for 2009 and the revised value added and establishment-specific weights put the growth for total industries (TOL BCDE) in the January to July period at 2.7 per cent. The lowered growth percentage in the early part of the year is due, among other things, to the fact that the final index for 2009 (-18.1%) did not fall by as much as the preliminary index (-20.9%). The lowered growth percentage is also explained by changed weight structure between industries. The value added shares of especially the forest industry, and the electrical and electronic industry diminished considerably in 2009. Respectively, the value added shares of e.g. the food industry and the chemical industry grew.
