Errors found at the CPA1 and CPA 2 level of the foreign trade indexes 2010 = 100
The foreign trade indexes 2010 = 100 published by the Finnish Customs, i.e. unit value index and volume index, have contained incorrect figures. Errors have been located both in the export and the import unit value and volume indexes for the period of December 2012 to December 2015 at the CPA1 level and for the period January 2013 to December 2015 for imports at the CPA2 level. The incorrect figures were due to a reference error in the new chain linking method used in the statistical production process. The corrections substantially affect the monthly point figures of these indices.
The incorrect figures have been published in the Monthly statistics on the foreign trade of goods publication from January 2013 to December 2015. The errors have been present in the following tables of the publication:
Table 9. Volume index, exports 2010=100
Table 10. Volume index, imports 2010=100
Table 11. Unit value index, exports 2010=10
Table 12. Unit value index, imports 2010=100
The errors have been present at the point figures and the point figure averages only at the CPA2 level for imports. Consequently, the indicators for these point figures have also been incorrect at CPA2 level. The point figures of all general indexes and CPA3 level indexes have been correct.
These monthly CPA2 level figures and their averages as well as the indicators published in the Uljas database were also erroneous under the same time period. Incorrect point figures and averages was furthermore published at CPA1 level for both exports and imports from December 2012 to December 2015. Also, the Uljas database contained errors in the indicators relating to these point figures. The erroneous data was first published in March 2013. The data of all the other indexes have been correct. The Uljas statistical database has been updated with the corrected figures 31.3.2016
The website of the Finnish Customs also has Excel spreadsheets, which contain the point figures of the indexes. In these tables there has been incorrect information for the above mentioned period. The errors have been corrected. The tables are available from the link below:
