Base shift for index series
Weights updated
In the calculation of index figures, weighting factors are used to reflect the share of underlying results in a publication group. At the same time as the base shift, these weights are updated so that they represent the present situation as accurately as possible. The year these weights refer to depends on the available data. In most cases it will be 2010 or later. All index series are subsequently rescaled to reference year 2010 (2010 = 100).
New tables
The index series based on 2010 = 100 will be published in new StatLine tables. Once these new tables are published, the present StatLine tables based on 2005 = 100 will no longer be updated, but will remain available. Most series based on 2010 = 100 will start with figures for 2005.
When?
The index series based on 2010 = 100 will become available at the time of publication of the first reporting period of 2013. For monthly statistics this means that index figures for January 2013 will be published in February or March 2013. The index figures for quarterly statistics will be published in May or June 2013.
