Data of the Volume Index of Industrial Output for January to April 2011 have been corrected

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.
