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 | |||
Owner occupied dwellings |
|||
3.7. Reference area | |||
Data are available for the country as a whole, there is no regional analysis. In comparison, the national HPI is published for different regions. |
|||
3.8. Coverage - Time | |||
The time series of OOHPI start in 2010. |
|||
3.9. Base period | |||
2015=100 |
|
|||
The following units are used: - Index point; |
|
|||
OOHPI is a quarterly statistics. |
|
|||
6.1. Institutional Mandate - legal acts and other agreements | |||
The basic act providing for the compilation of the harmonised indices of consumer prices (HICP) is the European Parliament and Council Regulation (EU) 2016/792 of 11 May 2016. The basic act is implemented by Commission Regulation (EU) 2023/1470 of 17 July 2023. |
|||
6.2. Institutional Mandate - data sharing | |||
None. |
|
|||
7.1. Confidentiality - policy | |||
Data is published up to the level of detail described in the Commission Regulation. |
|||
7.2. Confidentiality - data treatment | |||
Not relevant. |
|
|||
8.1. Release calendar | |||
There is no national publication of the OOHPI. The OOHPI is an aggregate of different existing statistics that is published separately at Statistics Norway’s website such as the national HPI, construction cost index for residential buildings and labour cost indices. |
|||
8.2. Release calendar access | |||
Not relevant. |
|||
8.3. Release policy - user access | |||
Not relevant. |
|
|||
Quarterly (OOHPI) and annually (weights) |
|
|||
10.1. Dissemination format - News release | |||
Not relevant. |
|||
10.2. Dissemination format - Publications | |||
Not relevant. |
|||
10.3. Dissemination format - online database | |||
Not relevant. |
|||
10.4. Dissemination format - microdata access | |||
Micro-data is not disseminated. |
|||
10.5. Dissemination format - other | |||
Not relevant. |
|||
10.6. Documentation on methodology | |||
As there is no national dissemination, no documentation on methodology is published. |
|||
10.7. Quality management - documentation | |||
It is written an internal documentation/publication of the establishment of the OOHPI. |
|
|||
11.1. Quality assurance | |||
OOHPI is to a large degree based upon already existing statistics which are all checked for completeness and consistency on their own. The aggregation of the different components is following basic HICP procedures and practices. The indices are calculated in SAS and treated consistently. All indices are controlled and reviewed before transmitted to Eurostat. Separate consistency checks are performed. |
|||
11.2. Quality management - assessment | |||
Not available. |
|
|||
12.1. Relevance - User Needs | |||
As there is no national dissemination of the data, there is no information on user needs, but the published HPI is widely used by the public sector (the Ministries, Norges Bank, etc) and the financial industry. It is also used by people with an interest in the housing market, for instance private persons, research institutions and the media. The index is an important indicator for sellers and buyers of dwellings as well as for valuation and estate agencies. |
|||
12.2. Relevance - User Satisfaction | |||
No information. |
|||
12.3. Completeness | |||
The OOH price indices do not fully meet the specifications set out in the Regulation as the OOH price index of self-built dwellings and major renovations is based on the construction cost statistics and is not consumer prices. |
|
|||
13.1. Accuracy - overall | |||
There are no estimates of overall accuracy of the OOH price indices. |
|||
13.2. Sampling error | |||
Sampling errors are not calculated. |
|||
13.3. Non-sampling error | |||
No quantitative assessments of non-sampling errors are made. |
|
|||
14.1. Timeliness | |||
There is no national dissemination of the OOHPI. The time lag between the end of the period to which the different OOH price indices relate and the production of OOHPI differ according to the different sub-indices. The HPI for new dwellings is available no later than 85 days after the quarter in question. The HPI for existing dwellings can be calculated 2-3 weeks after the quarter in question. The construction cost index is monthly, published normally approx. 10 days after the month in question. 'Major repairs & maintenance' is partly based on labour cost index statistics which is available at the latest approximately 70 days after the quarter in question. Prices of materials are available at the end of the month in question. |
|||
14.2. Punctuality | |||
Data is delivered to Eurostat on target date. |
|
|||
15.1. Comparability - geographical | |||
The OOHPI has no regional breakdown. |
|||
15.2. Comparability - over time | |||
The OOHPI has not suffered any breaks in continuity since the start of production. As of 2 quarter 2016 the OOHPI is revised back to 2011 due to a new HPI for new dwellings. Earlier the HPI for existing dwellings has been used as a proxy. |
|||
15.3. Coherence - cross domain | |||
There are no other national statistics or sources of OOH data. |
|||
15.4. Coherence - internal | |||
The HPI for new dwellings is used for OOHPI for new dwellings. Consistency checks (controls of rates of change) are made throughout the editing and calculation process. |
|
|||
The OOHPI is mainly based on already existing statistics. It does involve respondent burden, but data is used for multiple statistics. The time used to fill out web questionnaires (consumer prices of materials) is estimated to approx. 10 minutes per month, more for the construction cost indices. The annual cost for working on the OOHPI in the Division of price statistics is low. |
|
|||
17.1. Data revision - policy | |||
General HICP data revision policy is followed. |
|||
17.2. Data revision - practice | |||
The OOHPI data is not subjected to periodic and systematic revisions. As of 2 quarter 2016 the OOHPI is revised back to 2011 due to a new HPI for new dwellings. Earlier the HPI for existing dwellings has been used as a proxy. |
|
|||
