For indices for refuse collection and slurry pump, the index series for 2nd quarter of 2014 have been corrected. Older index series can be obtained by contacting Statistics Denmark. Please notice: As of quarter 1 of 2016 the base year for indices for refuse collection and slurry pump have been changed to 2015 = 100. This affects the index levels on the historical indices but not the development rates. The base period for the index for freight transport by road is 2nd quarter of 2022 = 100. This is also the case for index numbers from before this base period.
