Base year of the wage and salary indices changes

Starting from data concerning January 2018, the base year 2015=100 will be introduced in wage and salary indices. Data will be released for the first time with the new base year on 13 March 2018.

The indices are re-calculated from the beginning of 2015 in connection with the change of the base year. In this context, the data may have become revised and there the latest changes in the classification data are taken into consideration. The effects are of qualitative nature and are visible as revisions to data in some of the published industries. However, the changes are not significant and have no effect on the interpretation of the time series or the image of economic trends. In the following, database tables published with the old base year (2010=100) will no longer be updated.

The time series calculated with the new base year will be released in database tables whose structure has been renewed. In future, the tables will be formed by time variables, which means that the monthly, quarterly, semi-annual and annual data will be in separate database tables. In the same connection, the underlying metadata of the published industries have been changed. Renewing of the structure enables better machine readability of data and, for example, saving of automatically updated table selections and figures, as well as selection of key figures.

In connection with the base year change, the following alterations will be made to the published industries:

• The new industry group Retail sale in specialised stores total (TOL 474-477) is added to the statistics. The data of the industry are calculated starting from the data for January 2010.
• The new industry group Retail sale in specialised stores total (TOL 474-477) is added to the statistics. The data of the industry are calculated starting from the data for January 2010.
• The industry mentioned above is combined to the industry group Other retail trade, which in future includes the Standard Industrial Classification categories: 47595, 47630, 47650, 47764, 47781, 47784-5, 47789, 4779, 478, 4791, 47990. The data of the industry are calculated starting from the data for January 2010.
