An error has been detected in the calculation of the Volume Index of Industrial Output, which has an effect on the previously published volume index figures for January to April 2011. The erroneous figures for the early part of the year have now been corrected to the statistical releases and databases and to the data files delivered to customers.
The error has no effect on the image of economic trends given by other statistics, such as the Quarterly National Accounts or the Trend Indicator of Output.
The error is caused by that the revision in the weight structure at the turn of the year has not become updated to the calculation system. For that reason, enterprises' weights by size category inside three-digit industries have remained erroneous in the calculation of the index.
The table below contains the corrected and previously published erroneous data of the most important industries.

Statistics Finland has made revisions to the Consumer Price Index. The base period of the Consumer Price Index is updated every five years because changes take place in household consumption. The base year of the revised Index is 2010. At the same time the weight structure of the Index and the commodity basket of the price monitoring have been updated to correspond with consumption in the new base year.

The data on rents of office and business premises (6820) have been supplemented since the 4th quarter of 2008, and this influences the overall point figure of the producer price index for services starting from the 4th quarter of 2008. The revision also influences the point figures for the activities of Rents of office premises (6820A), Rents of office and business premises (6820) and Real estate activities (68 and L) starting from the same reference period.
Statistics Finland has calculated final indices for the years 2007 and 2008. The preliminary monthly volume index is calculated using data obtained from a sample of approximately 1,000 establishments or enterprises. The final annual volume index is calculated from the regional and industrial statistics on manufacturing calculated from structural statistics on manufacturing. More detailed description of the statistics is available at http://tilastokeskus.fi/meta/til/atoi_en.html. Changes in gross value at the most detailed classification level have been divided by change in the producer price index of each industry concerned. The preliminary annual change of the monthly index has been revised with the obtained coefficient.
The Bulletin of Statistics Internet database service data has been revised to match with the Bulletin of Statistics Publication. In consequense of this revision the amount of data in some of the tables in Bulletin of Statistics has been reduced.
