New dwellings; input price indices building costs, 2015 = 100

Nace rev2

Activities covered:The ‘New dwellings; input price indices building costs 2015 = 100’ covers the whole residential building construction sector. It does not cover site preparation, repair and maintenance. The covered activities fall under NACE Rev. 2 section F, Construction, Groups 41.20.

Size classes covered:The price index covers all newly built houses in the Netherlands.

List and definition of variables: The input price index shows the evolution of the building costs of residential buildings. There is no breakdown by region. The used variables are indices of buildingmaterials as used in an average dwelling and labour costs.

Planned changes in information collected: There are no planed changes in data collection.

Accounting conventions: The average of building costs of the year 2016 is calculated to be the base period. The input price index is calculated every month and indicates the flow during the month.

Reporting unit:There is no Reporting unit. We're using data that's already avialable at Statistics Netherlands.

Observation unit(s):The observation unit is a newly built dwelling.

Newly built dwellings.

The geographical area covered is the Netherlands.

The first year the indicator out was 1995.

The base year is 2017. This is the year the weightingschemes are based on.

The reference year is 2015.  This is the year the average of the figures is 100 (2015=100)

Input price indices building costs

The reference year is at present 2015. Once every five years the index will be revised.

Statistics Netherlands is fully independent in terms of its statistical operations with respect to methodology and publications. Independence was granted by the Royal Act of 1899 and reconfirmed by law in 1996 and 2003. Data provision was made compulsory by law in 1936. Confidentiality is guaranteed. Individual data are never published without consent. The Royal Act of 1899 and the Law of 1996 have been repealed by the Law of 20 November 2003. This Law on the Central Bureau of Statistics describes the independence of the director-general of Statistics Netherlands: “The director general shall determine the methods by which the studies included in the work programme and the multi-annual programme will be carried out and the manner in which the results of those studies will be published”. The Law of 2003 established the Central Bureau of Statistics and the Central Commission for Statistics. Section 3 states: “The task of the CBS is to carry out statistical research for the government for practice, policy and research purposes and to publish the statistics compiled on the basis of such research".

The price indices are not confidential.

A rolling 5 months-ahead release calendar is published in the schedule by date of Statistics Netherlands. When approximate release dates are given, the precise dates are announced on the last working day of the week prior to the release.

https://www.cbs.nl/en-gb/publication-calendar

Simultaneous release to all interested parties: Data are released simultaneously to all interested parties by issuing a press release through the internet website of Statistics Netherlands (https://opendata.cbs.nl/statline/#/CBS/nl/dataset/83887NED/table?dl=B48E).

Identification of internal government access to data before release: There is no internal government access to the data before their release to the public.

Transmission to Eurostat and further use of the statistics: As soon as the figures are published on the internet, they are also provided to Eurostat.

Monthly

There is no ministerial commentary on the occasion of the release of the data.

Further there is no news release.

Name of national paper publications: The indices are not published in paper publications.

Name of national electronic dissemination: The indices are published on the internet (https://opendata.cbs.nl/statline/#/CBS/en/).

You can find the online database by using the link: https://opendata.cbs.nl/statline/#/CBS/nl/dataset/83887NED/table?dl=B48E

There is no user access to microdata.

The data are transmitted monthly to Eurostat and disseminated monthly to national users by our online database Statline.

Dissemination of documentation on methodology and sources used in preparing statistics: Documentation of the used methodology is published on the internet (https://www.cbs.nl/nl-nl/onze-diensten/methoden/onderzoeksomschrijvingen/korte-onderzoeksbeschrijvingen/nieuwbouwwoningen-inputprijsindex-bouwkosten-2015-100)

Description of standard tables produced: The first release of the indices is published on the internet. The published indices are Material costs, Labour costs an Total building costs. They have no level of breakdown by region. They are published for the Netherlands as a whole.

There are internal quality reports that are used for the validation of the data to be published every month. There is no general report available describing the different quality indicators of these statistics.

There are different policies and procedures guarantying quality. Statical improvements are reviewed by an independent department. There is also a list of methods that have been accepted as best practice. New statistics should use these methods or only deviate with good reasons. Every month the results of STS statistics are validated by a independent stastistician.

The quality of the STS statistics are considered good. All quality aspects for STS statistics have been covered.

STS provide statistical information necessary to monitor the competitiveness and performance of the business community in the EU. The STS are used by different users (European Commission and ECB, national governments and central banks, economic analysts in private companies and financial institutions) and serve different purposes.

 Not available

The index is complete. There are no gaps or missing data parts and the series are according to the requirements of Eurostat.

The statistical errors are considered small. However it is an external source.

It is a census. We have 8 representative projects which represent all newly built dwellings in the Netherlands.

Response rate : There is no non-response as data from existing sources are used.

Actions to speed up or increase the rate of response : Not available.

Timeliness: The figures are published on the internet approximately 1 months after the end of the reference period.

Timetable of data collection: For this series we have no questionairs. We use data that is already available at SN. The data becomes available for calculations of the index approximately 4 weeks after the end of the reference month.

 All releases are published according to the release calendar.

The STS Regulations and the STS methodological guidelines are applied by the countries transmitting STS data. This ensures a good comparability between national data and good-quality European aggregates. However, the data are not 100% comparable with other countries. Each country may apply different collection methods (surveys, use of administrative sources) and different calculation procedures for the data. Within the Netherlands, no seperate geographical data is compiled, thus there is no comparability between regions.

The time series from 2012 on (2015=100) should be comparable over time, since no major changes in methodology or sources have been implemented in that period.

Before 2012 there are other series with another base year. All the series are linked to one historical series with reference year 2000.
https://opendata.cbs.nl/statline/#/CBS/nl/dataset/80444ned/table?dl=BDAF
These time series shoould also be comparable over time.

Dissemination of information that support statistical cross-checks and provide assurance of reasonableness: Not available

Confrontation with other data sets: Not available

The labour and material costs are coherent with the total.

The persons hour per year for SN is about 500 hours.

Data of the wages component become definite after aproximately 4 to 16 months. The material component becomes definite after 5 months.

The data are first published 4 weeks after the period under review. There is no database for revisions and corrections

Major changes in methodology are communicated centrally in advance. They are also briefly explained in the press releases and table explanations of the web-database (Statline) at the moment of publication using the new methodology.

The revisions are in practice conform the policy. This is also for the frequency.

Type of source: The index is based on at SN available data. The index uses Producer Prices indices and the index of Wages.

Frame on which the source is based: The Producer prices indices are based on a sample. The indices of the wages are based on the collectively negotiated wages rates (CAO).

Sample or census: Not applicable

Criteria for stratification: Not applicable

Threshold values and percentages: Not applicable

Frequency of updating the sample: The series is based on model pricing. The weighting sceme is updated every five year.

The data collection is monthly.

Questionnaires used in the survey: The index is based on already at SN available data.

Planned changes in national questionnaires: Not applicable

Data collection media: Not applicable

Planned changes in data collection methodology: Not applicable

The data is directly accessed by the database where we extract the data necessary on a regular base.

Is done by the ones who are making the Producer Prices Index and Index of Wages.

The data file structure is validated by the SDMX-converter. The results of STS construction are presented in excel-datatables and graphs. The validity of the results is done by examing the tables and graphs.

Estimates for non-response: Not applicable

Estimates for grossing-up to population levels: The results are not grossed up.

Type of index: It's a Laspeyres index

Method of weighting and chaining: The used variables are indices of wages and materials. These indices are weighted with their share in each of the representative dwellings in the base period (2017). Each dwelling is weighted with its share of the total numbers of new dwellings in the base period.

Planned changes in production methods: There are no changes planed.

There are no manipulations made on the data. Three indices are compiled, Materials, Labour and Total building costs.
