The Index of production in construction is a monthly statistic that contains an overall production index for the building and construction sector in total, as well as two sub-indices for construction and civil engineering respectively. The indices show the cyclical developments in the sector and are based on hours worked in the construction and civil engineering sector from the Working Time Accounts (ATR).

The index for Total construction covers the entire section F, i.e. groups F41, F42 and F43.

The index for Construction covers the construction of buildings, i.e. implementation of construction projects, demolition and preparatory site works, electrical installation and plumbing, as well as other building installation activities, etc.

The index for Civil engineering covers construction work, i.e. construction of roads and railways and construction of cable networks, etc.

These statistics follow the industrial groupings in NACE Rev. 2 which is a statistical classification that categorize enterprises by their most important economic activity.

The statistic covers construction.

Construction: The sector consist of section F in NACE Rev. 2.

The statistic covers hours worked in firm that produce construction services.

The population consist of firms in construction with employment.

The statistic covers Denmark as a whole.

These statistics covers the time period from January 2000 and onwards.

The index is has 2015 as its base.

The statistic is an index with 2015 as it's base year.

The statistic references months.

Section 8 of the Act on Statistics Denmark secures the legal ground for collecting the data.

The statistics fall under the following regulations:

Regulation (EU) 2019/2152 of the European Parliament and of the Council of 27 November 2019 on European business statistics

Commission Implementing Regulation (EU) 2020/1197 of 30 July 2020

Data Confidentiality Policy at Statistics Denmark.

There is no need to apply confidentiality in the published figures since the IPC is based on aggregated data.

The publication date appears in the release calendar. The date is confirmed in the weeks before.

The Release Calender can be accessed on our English website: Release Calender.

Statistics are always published at 8:00 a.m. at the day announced in the release calendar. No one outside of Statistics Denmark can access the statistics before they are published.

The statistic is published monthly

The statistics are published in the StatBank under Index of production in construction (IPC) in the following table:

• BYGPRO: Index of production in Construction (IPC) by industry

These statistics micro-data are not available.

Data are transmitted to Eurostat monthly.

There is no separate documentation on methodology for these statistics.

Results from the quality evaluation of products and selected processes are available in detail for each statistics and in summary reports for the Working Group on Quality.

Statistics Denmark follows the principles in the Code of Practice for European Statistics (CoP) and uses the Quality Assurance Framework of the European Statistical System (QAF) for the implementation of the principles. This involves continuous decentralized and central control of products and processes based on documentation following international standards. The central quality assurance function reports to the Working Group on Quality. Reports include suggestions for improvement that are assessed, decided and subsequently implemented.

The index is based in the WTA.

The objective with the statistic is to give interested users a quick overview of the cyclical trend in the construction sector.

The index is a requirement from Eurostat an has formerly only been send to Eurostat. After an improvement of the method is it decided to published it in Denmark. This decision has been discussed in the contact group for construction and dwelling statistics, which had approved the project.

The Index for Production in Construction complied with the recommendations and demands in Regulation (EU) 2019/2152 of the European Parliament and of the Council of 27 November 2019 on European business statistics, and Commission Implementing Regulation (EU) 2020/1197 of 30 July 2020 regarding short-term-statistics.

The margins of statistical uncertainty associated with the IPC are related to the statistical uncertainty of WTA.

In the long run (12 months), there is a good agreement with the National Accounts gross value added for the construction sector.

The index is based on the WTA and has no independent uncertainty. See the Documentation of the WTA.

Monthly data is published approximately two months after the end of the reference month.

Data is transmitted to Eurostat and published i Statbank within two months after the reference month.

All EU member states are obliged to provide the IPC under the guidelines in Regulation (EU) 2019/2152 of the European Parliament and of the Council of 27 November 2019 on European business statistics. These statistics can thus be compared internationally through Eurostat, where indices from the various EU member states are disseminated. However, international comparison must be made with that in mind, that there are two different recommended methods for compiling the statistics, which the EU member states can choose from.

Until autumn 2014 the IPC was calculated on basis of the quarterly gross value added in Construction from the National Account. There are no major breaks in the series from 2001 until 2014. From autumn 2014 the IPC has been calculated on the basis of working time account - corrected for productivity. The time series is calculated back to January 2000 with the new method.

Since the indices are based on working hours from the Working Time Accounts (WTA), there is a high degree of coherence with these statistics.

In connection with the change of method there was a comparison with index for gross value added in Construction from National Account. In the long run (12 months), there is a good agreement with the National Accounts gross value added for the construction sector.

In the former method there has been few problems of coherence between CC1, CC2 and the total. These problems seems not existing in the new method.

These statistics are based on administrative data. There is thus no direct response burden, in relation to the compilation of this statistic.

Statistics Denmark revises published figures in accordance with the Revision Policy for Statistics Denmark. The common procedures and principles of the Revision Policy are for some statistics supplemented by a specific revision practice. The revision is applied to both national data and the data transmitted to Eurostat.

Since the Danish IPC is calculated on the basis of hours worked from the Working Time Accounts (WTA) statistics the revisions follow the same pattern. The first publications of the production in the first and second month of any quarter, is partly estimated, which means that for every publication of data for the third month in a quarter, when all data is actually available, the published figures for the first two months of that quarter is revised.

In addition to these quarterly revisions there are annual revisions on the hours worked from the WTA which also means revisions in the IPC. The structural data is first available more that 15 months after the year of reference, and the revisions will therefore cause revisions to the WTA and hence the IPC over two years back in time.

The mean absolute revision (MAR) is calculated being 1,93 and the mean revision (MR) is calculated being 0,51 for the time series index Total construction.

The IPC is based on WTA, which are exclusively based on existing data sources, which are subsequently converted to the concepts used in the WTA.

Data is complied on a monthly basis.

The data is collected from the Working Time Accounts

Input to this statistic comes from the WTA, where quality of data is insured.

The monthly data from WTA are divided into building, civil engineering and total for Construction, which is a sum of hours worked for building construction and civil engineering.

Then the figures are compiled into an index with 2015 as base year. Followed this the figures are seasonally adjusted.

The statistic is adjusted for seasonal and calendar effects
