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 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.

The OOHPI covers the entire country. A regional OOHPI is not available.

The time series on OOHPI starts in the first quarter of 2010.

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.

Statistics Netherlands is assigned responsibility and authority to produce and provide the OOHPI data by the Dutch Statistics Act. Relevant EU legal act: Commission Implementing Regulation (EU) 2023/1470.

Not applicable.

Following the Statistics Netherlands Act, Statistics Netherlands cannot reveal any information which can be related to individual persons, households, enterprises or institutions.

Data is treated as other statistical data in compliance with the Dutch Statistics Act. In the dataset no data is available that can be related to individual persons or households.

There is a release calendar which is publicly accessible. New figures are released approximately 3 months after the end of the quarter.

There are no users with pre-publication access to the data.

Quarterly (OOHPI), annually (weights) and also monthly dissemination to Eurostat of items O.1.1.2 (Existing dwellings new to households) and O.1.2.1 (Major repairs and maintenance).

Statistics Netherlands does not publish articles for the OOHPI.

All data are checked for completeness and consistency with statistical concepts and definitions.

There is no national quality certification for the OOHPI available.

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.

There are frequent expert group meetings on construction and housing statistics.

We consider that the OOHPI fully meets the specifications set out in the Regulation.

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.

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

The OOHPI is normally transmitted before the deadline.

There are no regional figures available for the OOHPI.

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).

The HPI for newly built dwellings and the HPI for existing dwellings show similar trends.

Internal coherency is checked by visual comparison.

Statistics Netherlands is not able to provide information.

New figures for the most recent quarter will be provided as provisional data, which will be revised and finalised, if necessary, in time for the following publication and in compliance with Commission Implementing Regulation (EU) 2023/1470. 

Not applicable.

See below.

Administrative data, survey data, statistical domains (national accounts and construction statistics) and other sources are used for the compilation of the indices and the weights. 

Administrative data, survey data, statistical domains (national accounts and construction statistics) and other sources are used for the compilation of the indices and the weights. 

All data are collected quarterly except for 'Existing dwellings new to households' and 'Major repairs & maintenance'. The frequency of data collection for these last two is monthly.

The OOHIP source data are obtained by electronic databases which are provided to and by the central NSI office.

No planned changes in data collection in near future.

There is a systematic method for checking and validating the source data only for sub-indices: 'Purchase of new dwellings' and 'Existing dwellings new to households'. All unreliable observations are removed from the database.

See below.

 See below.

OOHPI is a Laspeyres-type price index.

Chain linked Laspeyres aggregation

Elementary aggregate weights for sub-indices are based on national accounts data. The weight reference period is t-2. The frequency of updating the OOHPI weights is yearly.

The weight reference t-2 is price-updated to the fourth quarter of t-1.

The chain linked Laspeyres method described by Eurostat is implemented.

See below.

Purchase of new dwellings: First binding contract (exact date is available).

Self build: Construction index is used as proxy. A new index-method is being developed.

Existing dwellings new to households: Transfer of ownership (exact date is available).

VAT is included in the price of newly built dwellings.

Other taxes are not included in the price of dwellings.

Government subsidies are included but unknown.

Land value is excluded from the weights for newly-built dwellings.

All dwellings sold by housing cooperatives to households are covered in the OOHPI.

Dwellings transacted by gifts are excluded from OOHPI coverage since there is no actual transaction price. New dwellings which are not sold to natural persons are excluded. Also moveable dwellings, such as houseboats and mobile homes, are excluded.

The source data only contains transactions of one property.

The source data only contains transactions of a whole property.

See below.

 The elementary aggregate formulae differ per sub-aggregate:

O.1.1.1.1 Purchase of new dwellings - Fisher Hedonic Double Imputation

O1.1.1.2a  Self build - Hedonic Laspeyres Characteristic 

O.1.1.1.2b Major renovations - Hedonic Laspeyres Characteristic 

O.1.1.2 Existing dwellings new to households - SPAR

O.1.1.3 Other services related to the acquisition of dwellings - Jevons

O.1.2.1  Major repairs & maintenance - Jevons

O.1.2.2 Insurance connected with dwellings - Dutot

O.1.2.3 Other services related to ownership of dwellings - Not applicable

Not applicable

Purchase of new dwellings: Stratification by dwelling type and region

Self build: Stratification by dwelling type and region

Major renovations:  Stratification by dwelling type and region

Existing dwellings new to households: By Sales Price Appraisal Ratio method

We use existing statistics for sub-aggregates 'Other services related to the acquisition of dwellings' (Service Price Indices) and 'Major repairs & maintenance' (Producer Price Indices).

There is no quality adjustment for 'Insurance connected with dwellings' as the index is a unit value index.

Not applicable

Vat is included only for sub-indices Purchase of new dwellings', 'Self build', 'Major renovations' and 'Major repairs & maintenance'.

No special adjustment methods are used.

Considered other changes for this year or next year to the coverage or compilation of OOH, that were not mentioned above: 

The OOH will be realigned in accordance with the new implementing act.

Purchase of new dwellings: Adaptive reuse dwellings will be added to the population

Self build: the compilation will be adjusted

Existing dwellings new to households: The direct calculation will be replaced with an aggregation of strata.
