3.1. Data description
The Owner-Occupied Housing Price Index (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:
- O.1. Owner-occupiers’ housing expenditure;
- O.1.1. Acquisitions of dwellings;
- O.1.1.1. New dwellings;
- O.1.1.1.1. Purchases of newly built dwellings;
- O.1.1.1.2. Self-build dwellings and major renovations;
- O.1.1.2. Existing dwellings new to households;
- O.1.1.3. Other services related to the acquisition of dwellings;
- O.1.1.1. New dwellings;
- O.1.2. Ownership of dwellings;
- O.1.2.1. Major repairs and maintenance;
- O.1.2.2. Insurance connected with dwellings;
- O.1.2.3. Other services related to ownership of dwellings.
- O.1.1. Acquisitions of dwellings;
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 is available for Denmark.
3.8. Coverage - Time
Data is available for 2002 and onwards.
3.9. Base period
2015=100.
The following units are used:
- Index point;
- Percentage change on the same period of the previous year (rates);
- Percentage change on the previous period (rates);
- Percentage share of the total (weights).
OOHPI is a quarterly statistics.
6.1. Institutional Mandate - legal acts and other agreements

None.
11.1. Quality assurance
All data are checked for completeness and consistency with OOH statistical concepts and definitions. The quality of the OOH index is routinely reviewed using a framework that is based on the OOH Manual and the European Statistical System (ESS) definition of quality.
11.2. Quality management - assessment
See under 11.1.
12.1. Relevance - User Needs
Eurostat/ECB.
12.2. Relevance - User Satisfaction
Not available.
12.3. Completeness
OOH is still under development and therefore some minor areas may not be fully covered. Furthermore, information is not included because of lack of data.
13.1. Accuracy - overall
Given the available data the OOH is perceived to be accurate and to reflect the overall market.
13.2. Sampling error
Not applicable.
13.3. Non-sampling error
With the exception of surveys on insurance companies, lawyers and on estate agents, all OOHPI indexes are based on administrative sources that cover the universe of dwelling transactions. However indices based on the Construction Cost Index are also partly based on samples as the Construction Cost Index partly relies on prices sampled in the Producer Price Index (PPI). The insurance survey was done using a cut-off sample, with the 5 most important insurance companies being surveyed. These companies accounted for almost 80% of all insurance provided to private households. The estate agents survey was done using a cut-off sample, with the 5 most important chains of estate agents being surveyed. These companies accounted for almost 70% of the market. The survey on lawyers is based on a random sample of approx. 25 law-firms.
15.1. Comparability - geographical
There is no geographical division of the data.
15.2. Comparability - over time
Figures for major repairs and maintenance plus prices for legal work in relation to the acquisition of dwellings has been introduced at a later stage causing breaks in the figures.
15.3. Coherence - cross domain
Not available.
15.4. Coherence - internal
The HPI and OOHPI are produced at the same time in the same system to ensure consistency between the two.
There is no burden on respondents as the data is sourced from administrative data sources.
The cost of production is app. 1500 euros per annum.
17.1. Data revision - policy
Data is revised one time after the first dissemination.
17.2. Data revision - practice
The OOH price indices for the last quarter are currently being revised with every new publication to include more and more transactions that have been added to the data register with considerable delay.
18.1. Source data
See below.
18.1.1. Prices
The major data sources are construction statistics, CPI data and administrative data from the tax authorities.
18.1.2. Weights
Weights are based on National Accounts data.
18.2. Frequency of data collection
The frequency of data collection is:
Weekly: Data on existing dwellings new to households.
Monthly: Data on purchase of new dwellings, data on insurance and data on other services related to acquisition of dwellings.
Quarterly: Data on self-build dwellings, data on major renovations and data on major repairs and maintenance.
18.3. Data collection
Most data is collected via electronic databases.
18.4. Data validation
Data used for the OOH indices comes from the systems of other statistics. So the validation process has already been performed in these systems.
18.5. Data compilation
See below.
18.5.1. Calculation and Aggregation
See below.
18.5.1.1. Index formulae
OOHPI is a Laspeyres-type price index.
18.5.1.2. Aggregation method
The sub-indices are weighted in the aggregation.
18.5.1.3. Derivation of sub-index and elementary aggregate weights
Sub-indices and elementary aggregate weights are based on national accounts data.
The current weight reference period is 2024, and this period is updated on an annual basis.
18.5.1.4. Price updating
Weights are available t-1 year for transactions and t-2 years for national accounts data. Currently we are not price updating to the fourth quater of t-1.
18.5.1.5. Chaining and linking method
The calculated indices are linked with the fourth quarter of the preceding year which is then chained with respect to the index reference period.
18.5.2. Other processing issues - OOH sub-indices for purchases of newly built dwellings and existing dwellings new to households
See below.
18.5.2.1. Timing for pricing
Date of the transfer of ownership from 2015Q1 onward. Data for periods before 2015Q1 are based on first binding contracts.
18.5.2.2. Treatment of VAT
VAT is not included in the price of newly built dwellings because purchases of dwellings are exempt from VAT.
18.5.2.3. Treatment of other taxes
Other taxes are not included in the price of dwellings.
18.5.2.4. Treatment of government subsidies
Not relevant.
18.5.2.5. Treatment of land
Land is included.
It is not possible to separate the price of land and property in the data sources.
18.5.2.6. Housing cooperatives
Housing cooperatives are not included in the OOHPI as very close to all cooperative housing units are existing dwellings. Extremely few units are newly built and none transformed from other sectors.
18.5.2.7. Treatment of non-market transactions
Not applicable.
18.5.2.8. Treatment of multi-object transactions
Multi-object transactions are not included.
18.5.2.9. Treatment of fractional transactions

See below.

Sub-indices are based on calculated indices from other statistics.
18.5.3.2. Replacements
