House Price Index (HPI) 2015=100

What does the survey comprise?

Purpose

The HPI measures the price development of dwellings purchased by households. The dwelling is located on Dutch territory and sold to a private person.

Target population

Sold dwellings, newly built and existing owner-occupied dwellings

Statistical unit

Owner-occupied dwellings, newly built and existing owner-occupied dwellings

Date/year survey started

The HPI is a weighted aggregate of the price index for newly built dwellings (PND) and the price index for existing dwellings (PED). The PED is calculated on a monthly basis and available from 1995. The PND is calculated on a quarterly basis and available from 2015. The HPI is therefore calculated on a quarterly basis and starting in 2015. The longer series for the PED before 2015 is published in the table Existing own homes; purchase price indices by type of dwelling 2015=100.

Frequency

Quarterly

Publication strategy

The price index figures of the HPI and PND are for one-quarter provisional figures. The number of sold dwellings are four quarters provisional. All figures of the PED are definite. Approximately 3 months after the reporting month, the figures will be published.

How is the survey conducted?

Survey type

To HPI is a weighted aggregate of the PND and PED. The weights represent the annual total value of purchase prices of newly built dwellings and existing dwellings. The weight is calculated by summing up the selling prices of all dwellings sold in a year. Each year new weights are calculated. A detailed description of the method can be found in the document ‘Survey method House Price Index '.
The PND is based on a sample of developers who sell newly built dwellings. The number of sold dwellings and the total value purchase prices associated with the PND are based on an integrated perception of housing transactions at the Land Registry. A detailed description of the method can be found in the document ‘Price index newly own homes 2015=100’.

The PED is based on an integrated perception of housing transactions at the Land Registry. A detailed description of the method can be found in the document ‘Price index existing own homes 2015=100'.
