Comparability

Comparability - geographical

If the overall national index is compared with the rent development in the consumer price index (CPI) and the EU harmonized consumer price index (HICP), the developments in 2021 and 2022 will not necessarily be identical. This is due to several conditions. 1. Following the calculation of the rent development for CPI and HICP, we have received additional data for 2021 for the private part of the rental housing market. This new data are used in the calculation of this statistics. 2. This statistic are calculated quarterly for 2021 and onwards, which could also cause some differences in relation to the rent development included in CPI and HICP, as this is only calculated quarterly from 2022. 3. Differences in the price reference periods will cause differences in the developments between the rent development in this statistic and the rent development calculated for the CPI and HICP.

From 2023, the developments in house rents in the CPI and HICP will be identical to the developments calculated in this statistic.

If the rent developments for the social housing part of the rental housing market in this statistic are compared with the publication from The National Building Fund (Landsbyggefonden) on rent statistics, where developments can also be found, the reported developments will not be identical, as there is difference in calculation method.

Comparability over time

The statistics have been compiled in the same way since 2021. The statistic are quarterly with reference period January, April, July and October.

Coherence - cross domain

Comparisons of this statistics with the rent statistics published by The National Building Fund will find that the resulting statistics differ due to differences in calculation methods.

Coherence - internal

The data are consistent.
