What does the survey comprise?
The computation of price index numbers to measure the development of the rent increase for dwellings in the Netherlands. The price movements are calculated as the rent change in July compared to July in the previous year expressed as a percentage.
Rented dwellings in the Netherlands.
Year survey started
The figures form part of the Consumer price index in the Netherlands. The figures over July when first published are provisional. A month later the definite publication is realized.
How is the survey conducted?
The study is based on an annual observation of rents charged by landlords of dwellings in Netherlands
The data are collected by means of an electronic survey among landlords of dwellings in the Netherlands. In addition, integral registers of rental properties from different landlords are used. The CBS will extend the use of integral data in the coming years.
Housing corporations, businesses, municipal housing institutions, corporations, private landlords and corporate investors.
The study consists of an integral part and a sample part. The integral part includes approximately 370,000 homes among 190 housing corporations and foundations. The sample comprises approximately 15,500 homes and covers approximately 2,800,000 dwellings administered by housing corporations, foundations and other reporters. The integral part and the sample part form the micro data from which the results are calculated
Checking and correction methods
Statistics Netherlands carries out checks for completeness and plausibility of incoming data. If data are incomplete or implausible more information is requested. When calculating the price movements, price changes as a result of housing improvement (renovation) adjusted. The renovation effect is the change in rent accounted for, by improved quality of housing. Unlike the renovation effect, the harmonization effect is included in the price development. The harmonization effect is the rent change caused by tenancy succession.
The sample for the rent survey is drawn from the basic registration addresses and buildings (BAG). The sample is stratified by region, type of owner and the Real Estate Appraisal Act. Per cell are the results levelled up to the population totals
Quality of the results
The large size of the sample of the rent survey, together with the integral part contribute to a high degree of accuracy of the results for the whole of Netherlands. The results on a more detailed level have a greater uncertainty
The results for the Netherlands are comparable in time.
Some methodological changes have taken place in 2015. The BAG is used as a sampling frame. For a part of the reporters integral data was used and the sample part has been extended. This has resulted in enhancing the accuracy of the results which will make it possible to publish at a more detailed level starting in 2015..
The data are checked for internal consistencies and completeness. When necessary, action is taken to verify the data. If the data are correct, the calculation of the price indices takes place and the results are verified and validated. The results are validated by staff who are not involved in compiling the figures.
