Definitions and explanations
Total retail trade refers to NACE 47, excluding 47.3.
Trade in consumables here refers to NACE 47.11 and 47.2.
Durables here refer to NACE 47.19 and 47.4-47.7.
All time series use the year prior to the year of the survey as their base year. Contact HUI Research for more detailed reports of the retail trade activities.
When the Retail Trade Index for a new month is published, the index for previous months is also revised. For the last month a new calculation has been made but other months may also be revised. The material is normally revised for twelve months retroactively. This is mainly due to new and revised information that has been received. Working day adjusted figures, seasonally adjusted figures and trend figures are always revised from January 1991 onwards.
Important message - a new model for seasonal adjustment and working day adjustment as well as a change in the reference year have been introduced as of January 2013
Seasonal adjustment and working day adjustment
The Retail Trade Index is one of the key indicators in the economic short-term statistics. The transfer to the new model for seasonal adjustment and working day adjustment means that the Retail Trade Index is handled according to principles in other surveys at Statistics Sweden. The new model follows the principle for seasonal adjustment at Statistics Sweden, which is designed according to guidelines and recommendations from Eurostat.
For more information about this new model, please contact Statistics Sweden at firstname.lastname@example.org.
Change of reference year
According to Eurostat requirements, the reference year for index series is to be changed every fifth year. This does not involve any changes in the development figures for the Retail Trade Index, because a chain index method is used.
