What does the survey comprise?
The computation of price index numbers for the calculation 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 a registration of rented dwellings and data from a stratified random survey. The composite panel of rented dwellings is taken from the registration of rental dwellings in the Netherlands.
The data are collected through a written survey of a fixed panel. Statistics Netherlands also uses an external digital registration.
Housing corporations, businesses, municipal housing institutions, corporations, private landlord and corporate investors.
Over 13,500 rental dwellings.
Checking and correction methods
Statistics Netherlands performs checks for completeness and plausibility of incoming data. If data are incomplete or implausible more information is requested. When calculating the price movement, the data are corrected for the effects of housing improvement (renovation). 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 change of tenancy.
The price movement is a weighted average of the changes in rent levels in different regions. The weighting for each region is determined by the number of dwellings in that region.
Quality of the results
The accuracy and representativeness of the rental movement is guaranteed by measuring prices for a very large and diverse number of dwellings. If the data are incomplete or implausible, more information is requested.
The method of calculation is unchanged and the figures are comparable.
The data are checked for internal consistency 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 from a different department than where the figures are compiled.
