|||
15.2. Comparability - over time | |||
Construction Cost Index (for dwellings) statistics are provided quarterly, annually and are comparable. Time series for CCI (for dwellings) exists from the reference year 1993. (The base period has changed: 1993=100, 10 fourth quarter 1999=100, first quarter 2011=100 and actually it is fourth quarter 2020=100). However, when comparing the two indices it should take in account that it is not the development of prices for similar buildings that are compared but different kinds of buildings that are constructed using different techniques, materials and in periods with different legal demands. This means that not only the weighting scheme but also the methods for collecting prices and calculating the indices are different. In order to make comparisons over time the indices can be chained to compare with previous calculations of the index. The average construction cost index is available from 1994 to 2010 referring to the statistical database providing a time comparability of 17 years (CC2 = Jlast-Jfirst + 1 = 17). Construction Cost Index by Expenditure Groups are available from 1994 to 2020 providing a time comparability of 27 years (CC2 = Jlast-Jfirst + 1 = 27). Construction Cost Index by Quarters by Expenditure Groups, Variables and Quarters are available from 2002 to 2023 referring to the statistical database providing a time comparability of 22 years (CC2 = Jlast-Jfirst + 1 = 22). The data are constantly checked to ensure their comparability over time. |
