3.1. Data description | |||
The OOHPI is based on the ‘net acquisitions’ approach, which measures changes in prices paid by households for the acquisition of dwellings that are new to the household sector and changes in other costs related to the ownership, and transfer of ownership, of dwellings. |
|||
3.2. Classification system | |||
The OOHPI is broken down into the following expenditure categories:
|
|||
3.3. Coverage - sector | |||
Households which are owner occupiers. |
|||
3.4. Statistical concepts and definitions | |||
The main statistical variables are price indices. |
|||
3.5. Statistical unit | |||
The basic unit of statistical observation are transaction prices of dwellings new to the household sector and of other products that the households acquire in their role as owner-occupiers. |
|||
3.6. Statistical population | |||
The OOHPI covers all prices paid by consumers for the acquisition of dwellings that are new to the household sector as well as other costs related to the ownership, and transfer of ownership, of dwellings. The weights of the sub-indices are equal to the total value of housing expenditure category involved, based on the Net Acquisitions Approach. |
|||
3.7. Reference area | |||
The OOHPI covers the entire country. A regional OOHPI is not available. |
|||
3.8. Coverage - Time | |||
The time series on OOHPI starts in the first quarter of 2010. |

|||
11.2. Quality management - assessment | |||

|
|||
12.1. Relevance - User Needs | |||
Eurostat and other European institutions (ECB) are the only known OOHPI users. The needs of this users are not fully met. A shortcoming of het OOHPI is the frequency. A monthly frequency is desired. We are currently exploring the possibilities. |
|||
12.2. Relevance - User Satisfaction | |||
There are frequent expert group meetings on construction and housing statistics. |
|||
12.3. Completeness | |||
We consider that the OOHPI fully meets the specifications set out in the Regulation. |
|
|||
13.1. Accuracy - overall | |||
The HPI for newly built dwellings as part of the OOH data collection is based on a sample survey for newly built dwellings. The types of survey, sampling, and price collection methods are designed to ensure sufficient coverage and timeliness. The accuracy of the HPI for newly built dwellings is assured by structurally monitoring confidence intervals (developed as part of grant number 801923). As the HPI for newly built dwellings has a major weight in OOH, this mostly determines the overall accuracy of the OOH. |
|||
13.2. Sampling error | |||
Not available. |
|||
13.3. Non-sampling error | |||
Not available. |
|
|||

The OOHPI is published 85 days after the end of the period to which the OOHPI relates. |
|||
14.2. Punctuality | |||

|
|||
15.1. Comparability - geographical | |||
There are no regional figures available for the OOHPI. |
|||
15.2. Comparability - over time | |||
In 2015 the OOHPI suffers from a break in continuity, due to an improvement in the price index for newly built dwellings. The observation data has changed as well as the method (simple stratified mean -> hedonic regression). |
|||
15.3. Coherence - cross domain | |||
The HPI for newly built dwellings and the HPI for existing dwellings show similar trends. |
|||
15.4. Coherence - internal | |||
Internal coherency is checked by visual comparison. |
|
|||
Statistics Netherlands is not able to provide information. |
|
|||
