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.

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.1.2. 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.

Households which are owner occupiers.

The main statistical variables are price indices.

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.

The target population is the set of all transactions of new dwellings to the sector purchased by households plus all relevant transactions connected to owner occupied dwellings.
HPI data for the purchases of new and existing dwellings are compiled on the basis of full transaction prices.
The HPI covers all transactions of dwellings made by households regardless of their final use. The weights for the two sub-indices are equal to the total value of dwelling transactions for new and existing dwellings, respectively. Both prices and weights include land value, as recommended by the Technical manual on Owner-Occupied Housing and House Price Indices.

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.

Commission Regulation (EU) no 2023/1470 of 17 July 2023 on methodological and technical specifications in accordance with Regulation (EU) 2016/792 on harmonised indices of consumer prices and the house price index.
No legal acts

At this time OOH price indices are not published by Statistics Denmark.

Quarterly (OOHPI) and annually (weights)

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.

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.

There is no geographical division of the data.

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.

Data is revised one time after the first dissemination.

The OOH price indices for the last two quarters 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. The revisions are also being carried out when appraisal values become available for newly built dwellings and when the weights are being updated with new information from National Accounts (Weight figures are annually revised for the latest years).

See below.

The major data sources are construction statistics, CPI data and administrative data from the tax authorities.

Weights are based on National Accounts data.

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.

Most data is collected via electronic databases.

Data used for the OOH indices comes from the systems of other statistics. So the validation process has already been performed in these systems.

See below.

See below.

OOHPI is a Laspeyres-type price index.

The sub-indices are weighted in the aggregation.

Sub-indices and elementary aggregate weights are based on national accounts data.

The current weight reference period is 2022, and this period is updated on an annual basis.

Not applicable.

The calculated indices are linked with the fourth quarter of the preceding year which is then chained with respect to the index reference period.

First binding contract.

VAT is not included in the price of newly built dwellings because purchases of dwellings are exempt from VAT.
