Please note! With the publication of the Construction cost index for residential buildings for the 1st quarter of 2024, the base year has been changed to 2021 = 100 and the weight basis has been updated. Going forward the statistic will be published in the table BYG43, which replaces BYG42 (2015 = 100). BYG42 is discontinued, and users are referred to BYG43 for future updates of Construction cost index for residential buildings. In BYG43, all indices have been rescaled to 2021 = 100. This affects historical index levels, but not quarterly or yearly development rates, although due to the rounding of decimals during the switch, development rates may differ in a magnitude of +/- 0.1 percentage points compared to previous listings.
