Comparability

Comparability - geographical

The Danish HICP is directly comparable with HICPs from other European countries that have been compiled according to the same EU regulations.

Comparability over time

In principle, the statistics are fully comparable over time. When making comparisons over longer periods, however, account should be taken of the fact that due to the weight changes and the continuous update of the sample, it is not the same basket of goods and services that is compared.

Before January 2001 was private hospitals not included in the HICP. Before January 2000, there are several differences as regards the coverage of goods and services over time.

A comprehensive list of weights for the consumer and net price indices as well as the harmonized index of consumer prices (HICP) from 1991 to today can be found on the Danish documentation page. The current division of goods and services can be seen in the list of weights for 2024.

Coherence - cross domain

The statistics can be compared directly with other countries' HICPs. The Danish HICP is also related to the national consumer price index. From January 2001 the only difference between the national consumer price index and the HICP is the coverage of goods and services, as owner-occupied dwellings is only recorded in the consumer price index and not in HICP. From January till December 2000, the only difference between the national consumer price index and the HICP is that both owner-occupied dwellings and private hospitals are only recorded in the consumer price index and not in the HICP. Before January 2000, there are differences in calculation and methodology between the two indices as well as several differences as regards the coverage of goods and services.

Coherence - internal

The data are consistent.
